Charcot-Marie-Tooth Disease Caused by Mutation in SPG11

Charcot-Marie-Tooth disease caused by mutation in SPG11 is a very rare, inherited nerve disease. Doctors also call it autosomal recessive Charcot-Marie-Tooth disease type 2X (CMT2X). In this condition, both copies of the SPG11 gene are damaged, so the body cannot make a normal form of a protein called spatacsin. This protein is important for the health and repair of long nerves in the legs and arms. When the protein does not work, the long “wire-like” parts of nerves slowly degenerate. This leads to weakness and wasting of muscles in the feet and hands, loss of feeling, and walking problems.MalaCards+2Monarch Initiative+2

Charcot-Marie-Tooth (CMT) disease caused by a mutation in the SPG11 (also called ALS5/KIAA1840) gene is a very rare inherited nerve disease. It belongs to the big CMT family, which is a group of genetic diseases that slowly damage the long nerves to the feet and hands. These nerves control movement and feeling. When SPG11 is mutated, the nerve fibers (axons) in the legs and arms gradually stop working properly, which leads to weakness, wasting of muscles, and loss of feeling, especially in the feet and lower legs.NCBI+2OUP Academic+2

SPG11 mutations more often cause a condition called hereditary spastic paraplegia, but some specific SPG11 changes can also cause an axonal CMT type (sometimes described as CMT type 2 with SPG11/ALS5 mutation). In real life, this means a person may have a mixture of problems: tight and stiff leg muscles (spasticity), weakness and wasting of distal muscles, foot deformities (like high arches and hammertoes), and numbness or burning pain.MDPI+2MalaCards+2

CMT2X due to SPG11 is an axonal neuropathy. This means the main damage is in the central part of the nerve fiber (axon), not mainly in the myelin covering. Nerve conduction tests usually show axonal damage with only mild slowing of conduction speed. The disease is slowly progressive, and most people remain able to walk for many years, although they may need braces or support.MalaCards+1

SPG11 mutations more commonly cause hereditary spastic paraplegia with thin corpus callosum, and sometimes juvenile ALS-like illness. In some families, however, the main problem is a CMT-type axonal neuropathy, which is why this form is described as Charcot-Marie-Tooth disease caused by mutation in SPG11.OUP Academic+2Springer Link+2

Other names

This condition appears in medical books and databases under several names. All of them refer to the same or very closely related disease pattern:

Charcot-Marie-Tooth disease, axonal, type 2X (CMT2X) – This name highlights that it belongs to type 2 CMT (axonal type) and uses “X” only as a subtype label, not related to the X chromosome.

Autosomal recessive Charcot-Marie-Tooth disease type 2 due to SPG11 mutation – This longer name explains that the disease is inherited in an autosomal recessive way and is caused by changes in the SPG11 gene.

Autosomal recessive axonal Charcot-Marie-Tooth disease type 2X (AR-CMT2X) – This form stresses both the recessive inheritance and the axonal damage pattern.

Charcot-Marie-Tooth neuropathy type 2X – Here the word “neuropathy” is used instead of “disease,” but it means the same thing: a disorder of peripheral nerves.

SPG11 Charcot-Marie-Tooth disease – This short name directly links the clinical picture of CMT to the causative gene SPG11.MalaCards+1

Types

Doctors do not yet have a strict, universal classification only for “SPG11-CMT.” However, based on reported patients, several clinical patterns can be described:OUP Academic+2Springer Link+2

1. Pure peripheral axonal CMT pattern
Some patients mainly have a typical CMT type 2 picture: slowly progressive weakness and thinning of the muscles in the feet and lower legs, high-arched feet (pes cavus), and reduced feeling in the feet and hands. There is little or no obvious stiffness or spasticity in the legs, and brain MRI may be normal or only mildly abnormal.

2. CMT with spastic paraplegia pattern
Other patients have both features of CMT and hereditary spastic paraplegia. They show distal weakness and sensory loss like CMT, but they also develop stiffness and increased reflexes in the legs. Walking becomes awkward due to a combination of foot drop and spasticity.

3. CMT with thin corpus callosum and cognitive changes
In some families, SPG11 mutations cause a complex picture with CMT-like neuropathy, spastic paraplegia, and thinning of the corpus callosum (the band that connects the two brain hemispheres). These patients may also have mild learning difficulties, slowed thinking, or behavior changes on top of peripheral nerve symptoms.

4. Early-onset childhood CMT2X
A group of patients show symptoms early in childhood, often around school age. They may have toe-walking, frequent falls, and delayed motor milestones. The disease progresses slowly, but disability can become more obvious in teenage years.

5. Later-onset adolescent or adult CMT2X
Other individuals remain fairly well until adolescence or early adulthood. They then start to notice foot weakness, tripping, or difficulty running. In these cases, the course is usually slower, and they may remain able to walk independently for decades.MalaCards+2PubMed+2

Causes

Remember that the main cause of this disease is always a pathogenic mutation in both copies of the SPG11 gene. The list below breaks down this cause into specific mechanisms and contributing factors:OUP Academic+2OUP Academic+2

1. Biallelic SPG11 loss-of-function mutations
Most patients have “loss-of-function” variants (nonsense, frameshift, or splice-site changes) in both copies of SPG11. These changes prevent the cell from making a full, working spatacsin protein, which directly leads to nerve damage.

2. Missense mutations in SPG11
Some patients have missense variants, where a single amino acid in spatacsin is changed. This can alter the protein’s structure, reduce its stability, or disturb its interaction with other proteins, causing similar clinical problems.

3. Autosomal recessive inheritance
Because the disease is recessive, a person must inherit one mutated SPG11 gene from each parent. Parents are usually healthy carriers but have a 25% chance in each pregnancy of having an affected child.

4. Consanguinity (marriage between relatives)
In families where parents are related (for example, cousins), the chance of both parents carrying the same rare SPG11 mutation increases. This is why SPG11-related disorders are often reported in populations with higher consanguinity rates.OUP Academic+1

5. Spatacsin protein dysfunction
SPG11 encodes spatacsin, which is involved in membrane trafficking and lysosome-related pathways in neurons. When spatacsin does not work properly, long axons cannot handle waste and membrane recycling efficiently, leading to axonal degeneration.OUP Academic

6. Impaired axonal transport
Neurons are very long cells, and they depend on transport systems to move nutrients and organelles down the axon. SPG11 mutations disturb these transport pathways, so the distal parts of nerves in the feet and hands are the first to suffer and degenerate.OUP Academic+1

7. Abnormal lysosomal and autophagy pathways
Studies from patient-derived neurons show accumulation of abnormal membranous bodies and defective autophagy. This means the cell’s “recycling system” is not working well, leading to build-up of toxic material and nerve injury.OUP Academic+1

8. Progressive axonal degeneration in peripheral nerves
Over time, the cumulative stress from transport and recycling problems leads to loss of axons in motor and sensory nerves, especially in the lower limbs. This is the direct anatomical cause of muscle wasting and loss of feeling.OUP Academic+1

9. Thin corpus callosum and central nervous system involvement
In many SPG11-related disorders, MRI shows thinning of the corpus callosum. Even in patients presenting mainly with CMT, subtle central changes may contribute to gait disability and cognitive slowing.MDPI+1

10. Neuroinflammation and microglial activation
Recent work suggests that inflammatory responses within the nervous system may modify disease severity in SPG11. Microglial activation and altered immune signaling may worsen neurodegeneration over time.Springer Link

11. Modifier genes for neuropathy
Other genes related to neuropathy or spastic paraplegia may act together with SPG11. Variants in such genes can change the age of onset or severity, even when SPG11 is the primary cause.OUP Academic+1

12. Environmental stress on long nerves
Factors such as repeated mechanical stress to the feet, long-standing poor footwear, or injuries do not cause the disease by themselves, but they may aggravate symptoms because already fragile nerves and muscles have less reserve.

13. Nutritional deficiencies as aggravating factors
Lack of vitamins important for nerves (for example, vitamin B12) does not cause SPG11-CMT, but if present, it can further damage peripheral nerves and make the genetic neuropathy worse.

14. Co-existing metabolic diseases (diabetes)
Diabetes mellitus can cause a separate neuropathy. If a person with SPG11-CMT develops diabetes, the nerve damage may progress faster, and symptoms may become more disabling.

15. Physical inactivity
When muscles are weak, people naturally move less. Reduced activity leads to secondary muscle wasting, joint stiffness, and poorer balance. This does not cause the original disease but strongly contributes to disability.

16. Contractures and skeletal deformities
Over time, chronic imbalance of muscles around the ankles and spine causes deformities such as pes cavus and scoliosis. These structural changes further limit mobility and add mechanical strain to nerves.MalaCards+1

17. Delay in diagnosis and rehabilitation
If the condition is not recognized early, patients may miss out on physiotherapy, orthotics, and other supportive care. Long periods without support allow avoidable muscle and joint problems to develop.

18. Inadequate symptom control (pain, spasticity)
Untreated neuropathic pain or leg spasticity can reduce sleep quality and daily activity. This constant stress indirectly worsens function and may speed up apparent decline.PubMed+1

19. Emotional stress and depression
Living with a chronic progressive disease can lead to anxiety and depression. Low mood can reduce motivation for exercise and self-care, which indirectly worsens mobility and quality of life.

20. Lack of access to specialist care
Because SPG11-related CMT is very rare, many regions lack experienced clinicians. Without specialist input, misdiagnosis or limited monitoring may occur, which again contributes to poor long-term outcomes.

Symptoms

Not every person will have all of the symptoms below. However, they are commonly reported in CMT2X due to SPG11 mutations:MalaCards+2PubMed+2

1. Distal muscle weakness in the feet and lower legs
The earliest sign is often weakness of the small muscles in the feet and ankles. People may struggle to lift the front of the foot (foot drop), have trouble running, or feel that their ankles “give way.”

2. Muscle wasting (atrophy) in the calves and feet
Because weak muscles are not used fully, they become thin and wasted over time. The lower legs may look very slim compared with the thighs, a typical “inverted champagne bottle” appearance seen in CMT.

3. High-arched feet (pes cavus) and toe deformities
Muscle imbalance pulls the foot into a high arch, with clawing of the toes. This makes shoes uncomfortable, increases pressure on certain areas, and may cause calluses, pain, or skin breakdown.MalaCards+1

4. Difficulty walking and frequent tripping or falling
Weakness and foot deformities make it hard to place the foot flat on the ground. People often lift the knees higher to avoid catching the toes, and they may trip more often on uneven surfaces.

5. Distal sensory loss (numbness and reduced feeling)
Many patients lose the ability to feel light touch, vibration, or position in the feet and sometimes in the hands. This numbness can increase the risk of injuries because small cuts or pressure sores may not be noticed.

6. Neuropathic pain or burning sensations
Some individuals describe burning, tingling, or shooting pains in the feet or legs. This is neuropathic pain, caused by damaged nerves sending abnormal signals to the brain.PubMed

7. Reduced or absent tendon reflexes
On examination, doctors often find that ankle jerks and sometimes knee jerks are weak or absent. This is a classic sign of peripheral neuropathy affecting the reflex pathway in the legs.OUP Academic+1

8. Weakness in the hands and intrinsic hand muscle wasting
As the disease progresses, the hands can also be affected. Fine movements like buttoning clothes, writing, or using small tools become more difficult, and the small muscles between the fingers may become thin.

9. Tremor or subtle shaking of the hands
Some patients develop a mild tremor when holding objects or trying to do precise movements. This can be due to both peripheral nerve damage and central involvement in SPG11-related disease.MalaCards

10. Gait disturbance from spasticity (in overlap forms)
In people who also have spastic paraplegia features, the legs may feel stiff with “scissoring” movement. This combines with foot drop to produce a very characteristic, effortful gait.MDPI+1

11. Balance problems and unsteady standing
Loss of proprioception (sense of joint position), weakness, and sometimes cerebellar signs make it hard to keep balance, especially in the dark or with eyes closed.

12. Fatigue and reduced stamina
Walking requires more effort because the muscles and nerves are not efficient. People often feel tired after short distances and may need frequent rest breaks.

13. Skeletal deformities (kyphosis, scoliosis, ankle contractures)
Long-standing muscle imbalance may lead to curvature of the spine or fixed positions of the ankles (contractures). These deformities can cause pain and further limit mobility.MalaCards+1

14. Bladder or urogenital dysfunction (in some patients)
A minority of patients have difficulties with bladder control or other autonomic symptoms, reflecting involvement of autonomic nerve fibers or central pathways described in SPG11-related disease.MalaCards+1

15. Mild cognitive or behavior changes (especially with thin corpus callosum)
Although many patients have normal intelligence, some may show slowed processing speed, attention problems, or mild behavioral changes due to central nervous system involvement typical of SPG11-related disorders.MDPI+1

Diagnostic tests

Doctors use a combination of clinical examination, bedside functional tests, laboratory and genetic tests, electrodiagnostic studies, and imaging to diagnose SPG11-related CMT and to distinguish it from other neuropathies.

Physical examination tests

1. Comprehensive neurological examination
The neurologist carefully checks muscle strength, tone, coordination, sensation, and reflexes in all limbs. In SPG11-CMT, this exam usually shows distal weakness and wasting in the legs and sometimes hands, reduced reflexes, and sensory loss. In overlap cases, there may also be increased tone and brisk reflexes in the legs, suggesting spasticity.OUP Academic+1

2. Muscle strength and tone testing (MRC grading)
Strength of each muscle group is graded using the Medical Research Council (MRC) scale from 0 to 5. In CMT2X, distal muscles of the feet and ankles are weakest, and tone may be normal or increased if spastic features are present. This structured testing helps track progression over time.

3. Detailed sensory examination
The doctor tests touch, pain, temperature, vibration, and joint position sense using simple tools like cotton wool, tuning forks, and safety pins. SPG11-CMT typically shows reduced vibration and position sense in the feet, which matches axonal sensory neuropathy.MalaCards+1

4. Reflex testing
Tendon reflexes at the ankles and knees are checked with a reflex hammer. Many patients with axonal CMT have weak or absent ankle reflexes. In those with strong spastic paraplegia components, knee reflexes may be brisk while ankle reflexes are absent, reflecting mixed central and peripheral involvement.OUP Academic+1

5. Gait and posture assessment
The clinician watches the patient walk on a flat surface, on heels and toes, and turn quickly. They look for foot drop, high-stepping gait, toe-walking, stiffness, and balance loss. Observing how the patient stands from a chair and maintains posture provides extra information about proximal strength and central involvement.

Manual bedside tests

6. Romberg test
The patient stands with feet together and then closes their eyes. If they sway or fall when the eyes are closed, it suggests that they rely heavily on vision to maintain balance because proprioceptive input from the feet is poor. This is common in sensory neuropathies like CMT.

7. Heel-to-toe (tandem) gait test
The patient walks in a straight line placing one foot directly in front of the other. Difficulty performing tandem gait, especially with eyes closed, indicates problems with balance and coordination, often due to sensory loss or cerebellar involvement seen in some SPG11 cases.MDPI+1

8. Foot and ankle range-of-motion assessment
The examiner manually moves the ankles and toes through their range. Limited movement, stiffness, or fixed deformities indicate contractures and structural changes. This helps decide whether orthotics, splints, or surgery might be needed to improve function.

9. Functional hand tests (grip and pinch)
Simple tools like a hand dynamometer measure grip strength, while timed tasks such as picking up small objects or buttoning simulate daily activities. In SPG11-CMT, these tests detect early hand involvement and allow monitoring of progression in a quantitative way.

10. Spasticity assessment (e.g., Modified Ashworth-type evaluation)
In patients with overlap spastic paraplegia, the examiner quickly moves the leg joints to feel resistance. Increased resistance that varies with speed suggests spasticity. Grading this helps to decide on physiotherapy, stretching, and possible antispastic medication.MDPI+1

Lab and pathological tests

11. Targeted SPG11 genetic testing
If clinical and electrodiagnostic findings suggest axonal CMT with possible central features, a targeted SPG11 gene test can be ordered. This looks for known or novel pathogenic variants across the gene. Finding biallelic pathogenic variants confirms the diagnosis.OUP Academic+1

12. Next-generation sequencing neuropathy or HSP panel
Many clinicians now order broader gene panels or exome sequencing that include SPG11 and many other neuropathy and spastic paraplegia genes. This approach is efficient, especially when the clinical picture is complex or overlapping. It also helps rule out other genetic causes of CMT2.ScienceDirect+1

13. Nerve biopsy (usually sural nerve)
In selected cases where genetic testing is inconclusive, a small piece of nerve from the leg can be examined under the microscope. In SPG11-related axonal CMT, biopsy typically shows loss of large myelinated fibers and signs of axonal degeneration, with relatively preserved myelin compared with demyelinating forms.OUP Academic+1

14. Routine blood tests to exclude acquired neuropathy
Blood tests such as complete blood count, glucose, thyroid function, vitamin B12 level, autoimmune markers, and others are done to rule out other causes of neuropathy. Although they do not diagnose SPG11-CMT, it is important to exclude treatable acquired causes that might coexist and worsen nerve damage.

Electrodiagnostic tests

15. Nerve conduction studies (NCS)
NCS measure how fast and how strongly nerves conduct electrical signals. SPG11-CMT usually shows reduced amplitudes of motor and sensory responses (due to axonal loss), with normal or only mildly reduced conduction velocities, a typical pattern for axonal CMT type 2.OUP Academic+1

16. Electromyography (EMG)
EMG uses a fine needle electrode to record electrical activity from muscles. In this disease, EMG often reveals chronic denervation changes, such as large motor units and reduced recruitment, especially in distal leg muscles. This supports the diagnosis of chronic axonal neuropathy.

17. Somatosensory evoked potentials (SSEPs)
In some centers, SSEPs are used to test the integrity of sensory pathways from the limbs to the brain. Abnormal SSEPs can show combined peripheral and central pathway involvement, which helps in understanding the full impact of SPG11 mutations.MDPI+1

Imaging tests

18. Brain MRI with corpus callosum evaluation
Magnetic resonance imaging of the brain is used to check for thin corpus callosum and other white-matter changes, which are characteristic of many SPG11-related disorders. Even when the main symptoms are peripheral, these MRI findings support the diagnosis and can help distinguish SPG11-CMT from other types of CMT.MDPI+1

19. Spinal MRI
Spinal imaging is usually normal or shows only mild changes in SPG11 disease, but it is often done to exclude other structural causes of spasticity or weakness, such as compression of the spinal cord. A normal spine with central and peripheral signs supports a hereditary neurodegenerative cause.

20. Peripheral nerve ultrasound or MR neurography
In some specialized centers, ultrasound or MR imaging of the peripheral nerves is used. In axonal CMT, nerves may appear relatively normal in size compared with demyelinating forms, but these techniques can document nerve anatomy, exclude compressive lesions, and add supportive information for complex cases.Charcot-Marie-Tooth Disease

Non-Pharmacological Treatments (Therapies and Others  Items)

Each item includes a short description, its purpose, and its basic mechanism (how it helps) in very simple words.

1. Physiotherapy (Physical Therapy)
   Physiotherapy uses exercises and stretches designed by a specialist to keep muscles as strong and flexible as possible. The purpose is to slow down contractures (permanent tightening) and help you keep walking independently for longer. The mechanism is simple: gentle, regular movement keeps joints mobile, maintains muscle strength, and improves blood flow, which together delay weakness and stiffness in CMT.nhs.uk+2Physiopedia+2

2. Occupational Therapy
   Occupational therapists focus on daily activities like dressing, writing, typing, cooking, and using the bathroom safely. The purpose is to help you stay independent in everyday life even if your hands and feet are weak. The mechanism is to teach simpler ways to do tasks and use adaptive tools (like special pens, grips, and cutlery) so that you need less force and less fine control from weak muscles.Physiopedia+1

3. Ankle-Foot Orthoses (AFOs) and Bracing
   AFOs are light plastic or carbon braces that support the ankle and foot, especially when there is “foot drop.” The purpose is to prevent tripping and falls and reduce ankle sprains. The mechanism is mechanical: the brace holds the foot in a more normal position during walking, which improves stability, corrects gait, and reduces energy use so you get less tired.ScienceDirect+1

4. Custom Footwear and Insoles
   Special shoes and insoles are shaped to fit cavus (high-arched) or other deformed feet. The purpose is to spread body weight evenly and protect the skin from pressure and blisters. The mechanism is to give strong support to the arches, cushion bony points, and improve foot alignment so the load on nerves, muscles, and joints is reduced, which lowers pain and slows deformity.ScienceDirect+1

5. Stretching Programs
   Daily stretching of calves, hamstrings, hands, and feet is simple but powerful. The purpose is to keep tendons and muscles long, so joints keep their normal range of movement. The mechanism is that slow, repeated stretches rearrange the collagen fibers inside muscles and tendons, which stops them from shrinking and reduces the risk of contractures and joint deformity.Muscular Dystrophy Association+1

6. Strengthening and Resistance Exercises
   Gentle strengthening with bands, light weights, or water exercises is often used. The purpose is to keep the muscles that still work as strong as possible without over-tiring them. The mechanism is that low-to-moderate resistance training increases muscle fiber size and improves nerve-muscle communication, which helps you walk and stand better and may delay muscle wasting.Physiopedia+1

7. Balance and Proprioception Training
   These exercises train the brain to use vision, inner ear, and remaining sensory signals to stay steady. The purpose is to cut down on falls and injuries. The mechanism is that standing on foam, using balance boards, or doing single-leg stance with support stimulates balance centers in the brain and improves the body’s automatic corrections when you start to fall.ScienceDirect+1

8. Gait Training and Walking Aids
   Physiotherapists can teach a safer way to walk and may suggest walking sticks, crutches, or a walker. The purpose is to make walking more energy-efficient and reduce stress on weak ankles and knees. The mechanism is that walking aids share body weight with the arms or device, improve symmetry of stepping, and reduce the risk of falls on uneven ground.ScienceDirect+1

9. Podiatry and Regular Foot Care
   Podiatrists (foot doctors) can trim nails, remove calluses, and treat small ulcers early. The purpose is to prevent serious infections and deformities. The mechanism is that careful skin and nail care reduces pressure points, prevents cracks in numb feet, and picks up wounds early, when they are small and easy to treat.ScienceDirect+1

10. Pain Psychology and Cognitive-Behavioral Therapy (CBT)
    Chronic nerve pain can affect mood, sleep, and school or work life. CBT and pain psychology help people change thoughts and behaviors around pain. The purpose is to reduce suffering, even if pain is still present. The mechanism is that coping strategies and relaxation techniques change how the brain processes pain signals and can reduce the intensity and emotional impact of pain.U.S. Food and Drug Administration+1

11. Hydrotherapy (Water-Based Exercise)
    Hydrotherapy uses pools for exercise and stretching. The purpose is to give a safe, low-impact way to move weak legs and arms. The mechanism is that water supports the body, reduces joint load, and provides gentle resistance in all directions, which helps strengthen muscles and improve flexibility without high risk of falls.Physiopedia+1

12. Respiratory Therapy (If Needed)
    Some people with advanced CMT or overlapping SPG11-related problems may develop breathing or cough weakness. The purpose of respiratory therapy is to maintain good lung function and prevent chest infections. The mechanism is that breathing exercises, assisted cough devices, and sometimes non-invasive ventilation at night keep the lungs inflated and clear of mucus.NCBI+1

13. Nutritional Counseling and Weight Management
    Extra body weight makes walking much harder for weak legs. The purpose of nutritional counseling is to reach and keep a healthy weight, support muscle health, and control other risks like diabetes. The mechanism is that balanced meals with appropriate calories, protein, and micronutrients reduce strain on joints and nerves and may improve energy and mood.NCBI+1

14. Fall-Prevention Education and Home Modifications
    Therapists may suggest removing loose rugs, improving lighting, and adding handrails at home. The purpose is to prevent serious injuries like fractures or head trauma. The mechanism is that a safer environment lowers the chance that weak ankles and numb feet will cause tripping, especially at night or on stairs.ScienceDirect+1

15. Vocational and School Rehabilitation
    Specialists can help you choose school subjects and later job roles that fit your physical abilities. The purpose is to maintain participation in study or work without worsening symptoms. The mechanism is to adapt tasks, tools, and schedules so you can use your strengths and avoid repetitive stress or heavy lifting that could speed up disability.Taylor & Francis Online+1

16. Assistive Technology (Keyboards, Voice Software, Splints)
    Tools such as ergonomic keyboards, speech-to-text programs, wrist splints, and special mice make hand work easier. The purpose is to reduce strain and pain in weak hands while you type or write. The mechanism is that these devices change the angle of joints, reduce the force needed, and spread pressure across a wider area so nerves and joints are less irritated.Charcot-Marie-Tooth Association+1

17. Psychological Counseling and Peer Support
    Living with a chronic genetic disease can cause sadness, anxiety, or isolation. The purpose of counseling and support groups is to protect mental health and build resilience. The mechanism is that talking with professionals and peers normalizes feelings, teaches coping skills, and can reduce depression and improve adherence to rehab plans.NeurologyLive+1

18. Genetic Counseling
    Because SPG11-related CMT is inherited (often autosomal recessive), families can benefit from genetic counseling. The purpose is to understand inheritance patterns, recurrence risk in future children, and options like carrier testing. The mechanism is careful collection of family history and genetic testing, followed by clear explanation so families can make informed decisions.MedlinePlus+1

19. Avoidance of Neurotoxic Medications and Toxins
    Some chemotherapy drugs (like vincristine) and certain toxins can worsen neuropathy. The purpose is to protect already fragile nerves. The mechanism is simple: by checking medicine lists and avoiding known nerve-toxic drugs when possible, the total damage to peripheral nerves can be kept lower over a lifetime.NCBI+1

20. Participation in Clinical Trials (When Available)
    For some CMT subtypes, including axonal forms, clinical trials may test new drugs, gene therapies, or cell-based therapies. The purpose is to access new treatments and help science move forward. The mechanism is that volunteers, under very strict safety rules, receive investigational interventions, allowing researchers to measure safety and any benefit over time.CMT Research Foundation+2PubMed+2

Drug Treatments

There is no approved drug that cures SPG11-related CMT. Medicines are mainly used to treat neuropathic pain, spasticity, mood problems, and general pain. Many are FDA-approved for other neuropathic conditions (like diabetic neuropathy or post-herpetic neuralgia) and are used off-label in CMT under specialist guidance.Springer Link+2diabetesresearchclinicalpractice.com+2

Safety note: Dose ranges below are typical adult ranges from FDA labeling and guidelines. Children and teens need different doses, so your doctor must decide the exact dose for you. Never start or change these drugs by yourself.

1. Pregabalin (Lyrica) – Anti-seizure/neuropathic pain drug
   Pregabalin is FDA-approved for neuropathic pain due to diabetes, post-herpetic neuralgia, and spinal cord injury. Typical adult doses are 150–300 mg/day, split into 2–3 doses, adjusted for kidney function. Its purpose in CMT is to reduce burning, shooting, or tingling pain from damaged nerves. The mechanism is binding to the α2δ subunit of voltage-gated calcium channels, reducing release of pain neurotransmitters in the spinal cord. Common side effects are dizziness, sleepiness, weight gain, and swelling.FDA Access Data+2FDA Access Data+2

2. Gabapentin (Neurontin and generics) – Anti-seizure/neuropathic pain drug
   Gabapentin is used for post-herpetic neuralgia and seizures and often for neuropathic pain in general. Adult doses usually range from 900–3,600 mg/day split into three doses, started low and increased slowly. The purpose is to calm overactive pain nerves in feet and hands. The mechanism, similar to pregabalin, is binding to calcium channel subunits and lowering excitatory neurotransmitter release. Side effects include dizziness, fatigue, and sometimes swelling or weight gain.Springer Link+2aan.com+2

3. Duloxetine (Cymbalta) – Serotonin–norepinephrine reuptake inhibitor (SNRI)
   Duloxetine is FDA-approved for diabetic peripheral neuropathic pain at 60 mg once daily in adults. The purpose in CMT is to reduce nerve pain and also treat anxiety or depression if needed. The mechanism is that increasing serotonin and norepinephrine in the spinal cord enhances descending anti-pain pathways, reducing pain signal strength. Side effects can include nausea, dry mouth, sleepiness, sweating, and, rarely, liver problems or increased blood pressure.FDA Access Data+2FDA Access Data+2

4. Amitriptyline – Tricyclic antidepressant
   Amitriptyline is widely used off-label for neuropathic pain, often at low doses such as 10–25 mg at night, slowly increased. The purpose is to improve sleep and reduce burning or stabbing nerve pain. The mechanism is blocking reuptake of serotonin and norepinephrine and blocking certain pain-related receptors in the spinal cord. Side effects include dry mouth, constipation, dizziness, and, in some people, heart rhythm changes, so careful monitoring is needed.Physiopedia+2diabetesresearchclinicalpractice.com+2

5. Venlafaxine – SNRI antidepressant
   Venlafaxine is sometimes used off-label for neuropathic pain at doses around 75–225 mg/day in adults. The purpose is to relieve nerve pain and depression together. The mechanism is similar to duloxetine: raising serotonin and norepinephrine levels, which strengthens the brain’s natural anti-pain pathways. Side effects may include nausea, headache, increased blood pressure, and withdrawal symptoms if stopped suddenly.aan.com+1

6. Topical Lidocaine 5% Patch (Lidoderm and similar)
   Lidocaine patches are FDA-approved for pain from post-herpetic neuralgia and are applied to painful skin for up to 12 hours in 24 hours. The purpose in CMT is to numb focused areas of burning pain without affecting the whole body. The mechanism is blocking sodium channels in local nerve endings, which stops pain signals from starting. Side effects mainly include mild skin irritation; serious side effects are rare if used as directed.FDA Access Data+2FDA Access Data+2

7. Capsaicin High-Strength Patch or Cream
   Capsaicin, from chili peppers, is used in creams or high-dose patches for neuropathic pain. The purpose is to reduce pain in a specific patch of skin, such as the top of the foot. The mechanism is that repeated exposure depletes substance P and desensitizes pain fibers, so they send fewer signals. Side effects include a strong burning feeling at first, which usually decreases over time.aan.com+1

8. Tramadol – Weak opioid with SNRI activity
   Tramadol is sometimes used as a second-line option for severe neuropathic pain when first-line medicines fail. Typical adult doses are 50–100 mg every 4–6 hours as needed, with a maximum daily limit and strict monitoring. The purpose is short-term control of strong pain. The mechanism combines weak opioid receptor action with serotonin and norepinephrine reuptake inhibition. Side effects include nausea, dizziness, constipation, and risk of dependence or withdrawal; misuse can be dangerous.aan.com+1

9. Standard Opioids (e.g., Oxycodone, Morphine – Carefully Selected Cases)
   In rare, severe cases, stronger opioids may be used under specialist care. The purpose is to treat severe pain that does not respond to other options. The mechanism is strong stimulation of opioid receptors in the brain and spinal cord to block pain transmission. Side effects are serious and include constipation, sleepiness, nausea, hormonal changes, and high risk of dependence and overdose, so they are usually last-resort and short-term.aan.com+1

10. Baclofen (oral) – Muscle relaxant for spasticity
    Baclofen is FDA-approved for spasticity from multiple sclerosis and spinal cord diseases. Adult oral dosing often starts at 5–10 mg three times daily and is slowly increased as needed. In SPG11-related disease with spasticity, the purpose is to reduce stiffness and spasms. The mechanism is acting as a GABA-B agonist in the spinal cord, lowering excitability of motor neurons. Side effects include sleepiness, dizziness, and, if stopped suddenly, serious withdrawal symptoms.FDA Access Data+2FDA Access Data+2

11. Tizanidine – Alpha-2 adrenergic agonist muscle relaxant
    Tizanidine is used for spasticity at doses titrated from 2–4 mg up to a maximum under medical supervision. The purpose is to reduce muscle tone and spasms, especially in stiff legs. The mechanism is reducing excitatory signals in the spinal cord through alpha-2 receptor stimulation. Side effects include sleepiness, dry mouth, low blood pressure, and possible liver enzyme changes.aan.com+1

12. Non-Steroidal Anti-Inflammatory Drugs (NSAIDs – e.g., Ibuprofen, Naproxen)
    NSAIDs are used for general musculoskeletal pain, joint strain, and headaches, not for neuropathic pain itself. The purpose is to reduce inflammation in joints and soft tissues stressed by abnormal gait. The mechanism is blocking COX enzymes and lowering prostaglandin production, which decreases inflammation and pain. Side effects include stomach irritation, kidney strain, and, with long-term use, higher cardiovascular risk.Springer Link+1

13. Acetaminophen (Paracetamol)
    Acetaminophen is a simple pain reliever used for mild to moderate aches. The purpose is to treat background pain or headaches without affecting platelets or the stomach. The mechanism is still partly unclear but involves action in the brain that reduces perception of pain and fever. Side effects are usually mild but overdose can cause severe liver damage, so daily limits must not be exceeded.Springer Link+1

14. Selective Serotonin Reuptake Inhibitors (SSRIs – e.g., Sertraline)
    SSRIs are not first-choice pain drugs, but they can help treat depression and anxiety that often go with chronic CMT. The purpose is to improve mood, energy, and coping. The mechanism is increasing serotonin in the brain, which lifts mood and may slightly influence pain perception. Side effects include nausea, sleep changes, and, rarely, increased suicidal thoughts in young people, so careful monitoring is essential.U.S. Food and Drug Administration+1

15. Botulinum Toxin Injections (Specific Use)
    In selected patients with severe focal muscle over-activity, botulinum toxin injections may be used. The purpose is to temporarily relax very tight muscles that cause deformity or pain. The mechanism is blocking acetylcholine release at the neuromuscular junction, causing local muscle relaxation for several months. Side effects include weakness in the injected muscle and, rarely, spread of toxin effects to nearby muscles.ScienceDirect+1

16. Sleep Medicines (Short-Term Use Only)
    Short-term sleep aids may sometimes be used in adults for severe insomnia linked to pain. The purpose is to restore a normal sleep pattern so the body and brain can recover. The mechanism depends on the drug (often enhancing GABA activity), making it easier to fall asleep. Side effects include daytime drowsiness, dependence, and falls, so they must be used very carefully, especially in people with weak legs.U.S. Food and Drug Administration+1

17. Vitamin B12 Injections (If Deficient)
    If blood tests show B12 deficiency, injections can be given. The purpose is to correct a reversible vitamin lack that can worsen neuropathy. The mechanism is that B12 is needed for myelin and DNA synthesis in nerves; replacing it allows better nerve repair. Side effects are usually mild, like local pain at the injection site, but doses must be guided by labs.NCBI+1

18. Antispasmodic Bladder Medicines (If Bladder Involvement)
    Some people with SPG11-related disease have bladder urgency or incontinence. Drugs like oxybutynin or newer agents may be used. The purpose is to reduce urgency and accidents. The mechanism is blocking muscarinic receptors in the bladder muscle to reduce involuntary contractions. Side effects include dry mouth, constipation, and blurred vision.NCBI+1

19. Antidepressants/Anxiolytics (Individualized Choice)
    Other antidepressants or anti-anxiety drugs may be chosen when mood symptoms are strong. The purpose is to stabilize mood, reduce anxiety, and improve adherence to therapy and exercise. The mechanism differs by drug but generally involves adjusting brain neurotransmitters. Side effects vary widely and must be monitored by a psychiatrist or neurologist.U.S. Food and Drug Administration+1

20. Medications for Co-existing Conditions (e.g., Diabetes, Thyroid Disease)
    If a person with SPG11-related CMT also has diabetes, thyroid disease, or vitamin deficiencies, medicines for those conditions are essential. The purpose is to prevent extra nerve damage from these common diseases. The mechanism is that good control of blood sugar, thyroid hormones, and other factors reduces additional harm to peripheral nerves.NCBI+2MedlinePlus+2

Dietary Molecular Supplements

Supplements should never replace medical care. Always ask your doctor before starting them, especially as a teenager. Evidence in CMT is limited; most data come from studies in other neuropathies.

1. Alpha-Lipoic Acid
   Alpha-lipoic acid is an antioxidant used in some countries for diabetic neuropathy at doses like 300–600 mg/day in adults. Its purpose is to reduce oxidative stress around nerves and support better blood flow. The mechanism is scavenging free radicals and improving endothelial function, which may slightly improve nerve conduction in some patients. Possible side effects include nausea and low blood sugar, especially when combined with diabetes medicines.Government of British Columbia+1

2. Acetyl-L-Carnitine
   Acetyl-L-carnitine helps move fatty acids into mitochondria for energy production. Doses in studies often range around 1–3 g/day in adults. The purpose is to support nerve energy metabolism and possibly nerve regeneration. The mechanism is improving mitochondrial function and increasing nerve growth factor levels in some models. Side effects may include mild nausea or restlessness.ej-med.org+1

3. Omega-3 Fatty Acids (Fish Oil)
   Omega-3 fats from fish oil (EPA/DHA) are anti-inflammatory. Typical adult doses in studies are 1–3 g/day of combined EPA/DHA. The purpose is to reduce low-grade inflammation and support cardiovascular health, which indirectly protects nerves. The mechanism is changing cell membrane composition and reducing production of inflammatory eicosanoids. Side effects include fishy taste and, in high doses, increased bleeding risk.ej-med.org+1

4. Vitamin D
   Vitamin D supports bone, muscle, and immune function. If blood levels are low, doctors may give doses like 800–2,000 IU/day or short high-dose courses. The purpose is to prevent bone weakness and muscle pain that can add to disability. The mechanism is improving calcium handling and modulating immune and muscle cells. Too much vitamin D can cause high calcium and kidney problems, so lab monitoring is needed.NCBI+1

5. B-Complex Vitamins (especially B1, B6 in Safe Doses, and B12)
   B vitamins help nerve metabolism. The purpose is to avoid deficiencies that worsen neuropathy. The mechanism is supporting myelin synthesis, energy production, and neurotransmitter formation. However, high-dose B6 over long periods can cause neuropathy, so doses must stay within safe limits set by a doctor. Side effects at proper doses are usually mild.NCBI+1

6. Coenzyme Q10 (CoQ10)
   CoQ10 is a mitochondrial cofactor involved in energy production. Adult doses used in studies vary from 100–300 mg/day. The purpose is to support muscle and nerve energy metabolism and reduce oxidative stress. The mechanism is shuttling electrons in the mitochondrial respiratory chain and acting as an antioxidant. Side effects are usually mild, such as stomach upset.ej-med.org+1

7. Curcumin (Turmeric Extract with Piperine)
   Curcumin is a plant compound with anti-inflammatory and antioxidant effects. Doses vary widely in supplements, often 500–1,000 mg/day with piperine to improve absorption. The purpose is to reduce chronic inflammation that might worsen nerve pain. The mechanism is blocking NF-κB and other inflammatory pathways. Side effects include stomach discomfort and, rarely, interactions with blood thinners.ej-med.org+1

8. Magnesium (In Safe Doses)
   Magnesium supports nerve and muscle function. The purpose is to prevent cramps and improve muscle relaxation if levels are low. The mechanism is stabilizing cell membranes and acting as a natural calcium blocker at some receptors. Too much magnesium from supplements can cause diarrhea and, in kidney disease, dangerous levels, so dosing must be guided.ej-med.org+1

9. N-Acetylcysteine (NAC)
   NAC is a precursor of glutathione, a major antioxidant. The purpose is to raise antioxidant defenses and reduce oxidative stress that can damage nerves. The mechanism is supplying cysteine to help cells make more glutathione. Side effects may include nausea and, rarely, allergic reactions. Evidence in hereditary neuropathy is limited and mostly experimental.ej-med.org+1

10. Probiotics (Gut Microbiome Support)
    Probiotics are live “good” bacteria given in capsules or foods. The purpose is to support gut health, which may indirectly affect inflammation and immune balance. The mechanism is improving gut barrier function and modulating immune responses. Side effects are usually mild gas or bloating; they should be used carefully in people with severe immune problems.ej-med.org+1

Drugs for Immunity Support, Regenerative and Stem-Cell-Related Concepts

There are no approved stem-cell or gene-therapy drugs for SPG11-related CMT as of late 2025. All options in this section are research concepts or clinical-trial-level ideas, not treatments you can buy or use on your own.PubMed+2PubMed+2

1. Gene Therapy Targeting CMT Genes
   Gene therapy aims to correct or silence faulty genes using viral or non-viral vectors. The purpose for CMT is to fix the underlying mutation and stop further nerve damage. The mechanism can be adding a normal gene copy, silencing a toxic gene, or editing the gene sequence. Early trials in other CMT types and reviews show promise but also major challenges with safety, delivery, and cost. No approved SPG11 gene therapy exists yet.PubMed+2Institut Myologie+2

2. HDAC6 Inhibitors (e.g., AGT-100216 – Investigational)
   HDAC6 inhibitors are small molecules being tested in CMT to improve axonal transport and nerve health. The purpose is to protect and possibly repair long peripheral axons. The mechanism is changing acetylation of proteins involved in axonal transport, which may help nerves clear damaged components and maintain function. Early phase human trials are underway, but dosing and long-term safety are still being studied.Charcot-Marie-Tooth Disease+1

3. Mesenchymal Stem Cell (MSC) Therapy (Experimental)
   MSC therapy uses stem cells from bone marrow, fat, or umbilical cord, given by injection or infusion. The purpose in neuropathy research is to support nerve repair and reduce inflammation. The mechanism includes release of growth factors, modulation of immune cells, and possibly direct differentiation into support cells. Trials in diabetic neuropathy show some improvement in nerve conduction, but this is not standard care and carries unknown long-term risks.MDPI+3ClinicalTrials.gov+3ScienceDirect+3

4. Neurotrophic Factor-Based Therapies (e.g., IGF-1, BDNF, NT-3 – Experimental)
   Neurotrophic factors are natural proteins that help neurons survive and grow. The purpose of using them as therapy is to directly support damaged nerves and promote regeneration. The mechanism is binding to specific receptors on nerve cells and triggering growth and survival pathways. Animal and early human studies in peripheral neuropathies show promise, but delivering these proteins safely and effectively over time is still a major challenge.ScienceDirect+3PubMed+3PubMed+3

5. Immune-Modulating Drugs in Overlapping or Misdiagnosed Cases
   In some patients initially labeled as hereditary neuropathy, later tests show an immune-mediated neuropathy like CIDP, where treatments like IVIG or steroids can help. The purpose in those cases is to calm an over-active immune system attacking nerves. The mechanism depends on the drug (antibodies supply, immune cell suppression, etc.). For clear SPG11-related CMT, routine immune-suppressing drugs have no proven benefit and can cause serious side effects.NCBI+1

6. Participation in Regenerative Clinical Trials (Various Agents)
   Different experimental agents, including muscle-targeted drugs (like NMD670) and plasmid-based gene medicines, are being tested in CMT adults. The purpose is to preserve strength and function longer than standard rehabilitation alone. The mechanism varies (improving neuromuscular junction function, altering gene expression, or boosting regeneration signals). These are only available in controlled trials, where doses and safety are closely monitored.Taylor & Francis Online+3Charcot-Marie-Tooth Disease+3ClinicalTrials.gov+3

Surgeries

1. Tendon Transfer Surgery for Foot Drop
   In tendon transfer surgery, a stronger working tendon (for example from the back of the leg) is moved to help lift the front of the foot. The purpose is to correct persistent foot drop that braces alone cannot manage and to improve walking safety. The mechanism is mechanical: the transferred tendon now pulls the foot upward, helping clear the ground while walking and reducing tripping.ScienceDirect+1

2. Osteotomy for Cavovarus Foot Deformity
   Osteotomy involves cutting and reshaping foot bones to correct high arches and inward turning of the heel. The purpose is to improve foot alignment, reduce pain, and prevent pressure sores. The mechanism is changing the bone angles so that weight is spread more evenly across the foot, which makes walking more stable and less painful.ScienceDirect+1

3. Achilles Tendon Lengthening
   If the Achilles tendon becomes very tight, surgeons can lengthen it through small cuts or more open surgery. The purpose is to allow the heel to touch the ground properly and reduce toe-walking. The mechanism is giving extra length to the tendon so the ankle can bend upward more easily, improving gait and reducing forefoot pressure.ScienceDirect+1

4. Correction of Hammertoes and Toe Deformities
   In some people, bent toes cause pain, calluses, and difficulty finding shoes. Surgery may straighten the toes, fuse small joints, or remove bone pieces. The purpose is to relieve pain, reduce ulcer risk, and allow comfortable footwear. The mechanism is mechanical realignment of the toe bones and tendons so the toes lie flatter and function better.ScienceDirect+1

5. Spinal Surgery for Severe Scoliosis (Selected Cases)
   If CMT and associated muscle imbalance lead to severe spinal curvature, spinal fusion or other corrective surgery may be considered. The purpose is to prevent progression of scoliosis that could affect breathing or cause major pain. The mechanism is stabilizing the spine with rods and screws so it stays in a more normal shape.NCBI+1

Preventions

Here “prevention” means preventing complications, not the gene mutation itself.

1. Keep a healthy body weight to reduce strain on weak legs and feet.NCBI+1

2. Do regular, gentle physiotherapy and stretching to prevent contractures and joint deformity.nhs.uk+1

3. Use orthoses and proper footwear early to lower the risk of falls and ankle injuries.ScienceDirect+1

4. Inspect feet daily for blisters, sores, or color changes, and treat problems early.ScienceDirect+1

5. Avoid smoking and excess alcohol, which can worsen circulation and nerve health.NCBI+1

6. Manage other diseases like diabetes, thyroid problems, and vitamin deficiencies carefully.MedlinePlus+1

7. Avoid neurotoxic medicines when possible (for example, vincristine) and always tell doctors you have hereditary neuropathy.NCBI+1

8. Make home safety changes (handrails, good lighting, no loose rugs) to prevent falls.ScienceDirect+1

9. Keep vaccinations up to date, especially flu and pneumonia shots, to reduce infection risk if mobility or breathing is limited.NCBI+1

10. Attend regular follow-up with neurology, physiotherapy, and orthopedics so changes can be picked up early and treated quickly.Taylor & Francis Online+1

When to See Doctors

You should see your doctor or neurologist regularly for routine check-ups, but there are times when you should seek help as soon as possible:

• When you notice rapid worsening of weakness, new severe pain, or a sudden drop in walking ability, as this may signal an extra problem on top of CMT (for example, infection, injury, or another type of neuropathy).NCBI+1

• If you develop shortness of breath, frequent chest infections, or morning headaches, which can mean breathing muscles are getting weaker and you may need respiratory tests.NCBI+1

• When you find ulcers or infected wounds on your feet, especially if they do not heal quickly, because deep infections and bone involvement are serious complications.ScienceDirect+1

• If you have severe mood changes, sadness, anxiety, or thoughts of self-harm, you need urgent mental health support; chronic illnesses strongly increase this risk.U.S. Food and Drug Administration+1

• Before starting any new medicine, supplement, or intense exercise plan, you should confirm it is safe for someone with hereditary neuropathy, especially as a teenager.Springer Link+1

Because you are under 18, it is important that a parent or guardian and your doctor make decisions together about medicines, supplements, and therapies.

What to Eat and What to Avoid

1. Eat plenty of colorful vegetables and fruits
   These foods provide vitamins, minerals, and antioxidants that support general nerve and muscle health. Try to fill half of your plate with vegetables and fruits most days. Limit sugary drinks and desserts that give calories without nutrients.NCBI+1

2. Choose lean protein at each meal
   Fish, eggs, beans, lentils, and lean meats provide amino acids needed to maintain muscle and repair tissues. Very high-fat processed meats should be limited because they add unhealthy fats and salt that stress the heart and blood vessels.NCBI+1

3. Prefer whole grains over refined grains
   Brown rice, whole-wheat bread, and oats help keep blood sugar steady. This is important because diabetes and big blood-sugar swings can damage nerves further. Try to avoid large amounts of white bread, pastries, and sugary cereals.MedlinePlus+1

4. Use healthy fats and limit trans fats
   Olive oil, nuts, seeds, and avocado provide healthy fats that support cell membranes and reduce inflammation. Fried fast foods and packaged snacks often contain trans fats and too much omega-6, which can increase inflammation and weight gain.ej-med.org+1

5. Stay well hydrated with water
   Water is important for circulation, digestion, and muscle function. Aim for regular water intake through the day. Sugary sodas and energy drinks should be rare because they add sugar and may worsen weight gain and energy crashes.NCBI+1

6. Get enough calcium and vitamin D from food
   Low-fat dairy, fortified plant milks, tofu, and green leafy vegetables can support bone strength. Strong bones are vital when muscles are weak and falls are more likely. Very high-dose supplements without blood tests should be avoided because they can cause harm.NCBI+1

7. Limit alcohol (or avoid it completely as a teen)
   Alcohol can directly damage nerves and worsen balance and judgment, increasing fall risk. Because you are under legal drinking age and have a nerve condition, avoiding alcohol is the safest choice.NCBI+1

8. Avoid crash diets and extreme fasting
   Very low-calorie diets can cause muscle loss and make weakness worse. Instead, follow a steady, balanced eating plan designed with a dietitian if you need to lose weight. Avoid strong appetite-suppressing pills or unverified “fat-burners,” especially bought online.NCBI+1

9. Be cautious with herbal products and “miracle cures”
   Many advertised herbal mixes claim to “regrow nerves” or “cure neuropathy,” but most have no solid scientific proof and some can harm the liver or interact with medicines. Any supplement should be checked by your doctor first.ej-med.org+1

10. Plan meals around energy needs and therapy times
    Eating enough before physiotherapy helps you train well without feeling weak, but very heavy, high-fat meals right before exercise can make you sluggish. Organizing small, balanced meals and snacks around your rehab schedule can support better performance and recovery.Physiopedia+1

Frequently Asked Questions

1. Is SPG11-related CMT curable?
   No, at present SPG11-related CMT is not curable. Treatments focus on easing symptoms, protecting function, and preventing complications. Research on gene therapy, stem cells, and new drugs is active and promising, but these options are still in trials and not available as routine treatment yet.PMC+2PubMed+2

2. Will physiotherapy really make a difference if my genes are the problem?
   Yes. Physiotherapy cannot change your genes, but it can slow down stiffness, maintain strength in muscles that still work, and delay joint deformities. Over years, this can mean the difference between walking independently and needing a wheelchair much earlier.nhs.uk+2Muscular Dystrophy Association+2

3. Can medicines like pregabalin or duloxetine stop the disease?
   No. These drugs treat pain, not the underlying genetic process. They help reduce burning or stabbing sensations and can improve sleep and mood, which is still very important for quality of life. They do not stop nerves from slowly degenerating.FDA Access Data+3Springer Link+3diabetesresearchclinicalpractice.com+3

4. Are pain medicines addictive?
   Most first-line neuropathic pain drugs, like gabapentin, pregabalin, duloxetine, and amitriptyline, have low addiction potential when used as prescribed. Opioids and tramadol carry clear dependence and misuse risks, especially with long-term use, so doctors try to avoid or limit them and monitor closely.aan.com+2U.S. Food and Drug Administration+2

5. Will braces and orthoses make my muscles weaker?
   When fitted correctly, braces usually protect joints and reduce strain instead of causing weakness. They help you walk more safely and allow you to do more activity, which maintains strength. Physiotherapists will still encourage active exercises so muscles do not “switch off.”ScienceDirect+2www.slideshare.net+2

6. Can I play sports if I have SPG11-related CMT?
   Many people with CMT can do low-impact sports like swimming, cycling on a stable bike, and carefully chosen gym exercises. Very high-impact sports, contact sports, or those with high fall risk may not be safe. Your rehab team can help choose and adapt sports that match your balance and strength.Physiopedia+2Charcot-Marie-Tooth Disease+2

7. Will this disease affect my brain or thinking?
   SPG11 mutations can sometimes be linked with cognitive changes or features of hereditary spastic paraplegia. Some people have mild learning or thinking problems, but others do not. Regular review with neurology and, if needed, neuropsychology can track these areas and offer support strategies.MDPI+2NCBI+2

8. Can diet alone fix my neuropathy?
   No diet can fix the gene mutation or fully repair nerves. However, a balanced diet supports overall health, keeps weight in a healthy range, and prevents extra damage from diabetes or vitamin deficiencies. So, food is a helpful support, not a cure.NCBI+2MedlinePlus+2

9. Is stem cell therapy ready for routine use in CMT?
   No. Stem cell and regenerative therapies for peripheral neuropathy are still in the research and clinical trial phase. Some studies in diabetic neuropathy and nerve injury show early benefits, but risks, long-term safety, and best protocols are not yet clear. Such treatments should only be taken inside approved clinical trials.MDPI+3ClinicalTrials.gov+3PMC+3

10. Could I pass this condition to my children in the future?
    SPG11-related CMT is usually autosomal recessive, meaning both parents carry one mutated copy. Future child risk depends on your partner’s genes. Genetic counseling can estimate this risk and explain options like carrier testing or prenatal diagnosis in the future.MedlinePlus+2NCBI+2

11. What age do symptoms usually start?
    In SPG11-related neuropathies, symptoms often begin in childhood or adolescence with clumsiness, foot drop, and frequent tripping, but exact timing varies widely. Some people show signs later in adult life. regular follow-up helps track progression from early stages.OUP Academic+2ScienceDirect+2

12. Will I definitely need a wheelchair?
    Not everyone with SPG11-related CMT needs a wheelchair, and the age at which mobility changes occur is very variable. Good rehab, braces, surgery when needed, and prevention of secondary problems can help many people stay on their feet longer.ScienceDirect+2Muscular Dystrophy Association+2

13. How often should I see my neurologist and rehab team?
    Most people benefit from at least yearly reviews with neurology and more frequent physiotherapy and orthotic checks, especially during periods of growth or change. Your schedule may be more frequent if symptoms progress quickly or if new treatments are being tried.Muscular Dystrophy Association+2ScienceDirect+2

14. Is there anything my family should avoid saying or doing?
    Supportive families are very important. It helps when relatives avoid blaming you for limitations, pushing you to do unsafe activities, or promising “miracle cures” they saw online. Instead, they can listen, attend appointments with you, and help you follow safe, evidence-based plans.U.S. Food and Drug Administration+1

15. What is the most important thing I can do now?
    The most important steps are: stay in regular contact with your medical team, follow your physiotherapy and foot-care programs, keep a healthy lifestyle, and ask questions whenever you are unsure. Learning about your condition, like you are doing now, is a powerful way to protect your health and plan for the future.NCBI+2Muscular Dystrophy Association+2
