Autosomal Recessive Axonal Charcot-Marie-Tooth Disease with Pyramidal Features

Autosomal recessive axonal Charcot-Marie-Tooth disease with pyramidal features is a very rare, inherited nerve disease. It mainly affects the long “wires” of the nerves (axons), which carry signals from the brain and spinal cord to the muscles and back from the skin. Because the nerves are damaged, the muscles in the feet, legs, hands and sometimes other parts slowly become weak and thin, and feeling (sensation) can be reduced. “Pyramidal features” means there are extra signs that the upper motor neurons in the brain and spinal cord are also affected, such as stiff muscles, brisk reflexes and sometimes spasticity. This disease is autosomal recessive, so a person becomes sick when they inherit a faulty copy of the gene from both parents; the parents are usually healthy carriers. Researchers have linked some cases to mutations in genes such as SPG11 and LMNA, which are known to cause autosomal recessive axonal Charcot-Marie-Tooth disease. pfmjournal.org+3NCBI+3OUP Academic+3

Autosomal recessive axonal Charcot-Marie-Tooth disease with pyramidal features is a very rare inherited nerve disease that affects both the long peripheral nerves (to the feet and hands) and, to a milder degree, the “pyramidal” pathways in the brain and spinal cord that control movement. In simple words, it is a genetic problem of the nerves that causes slowly progressive weakness and wasting in the feet and hands, with extra signs of stiff or over-active reflexes in the legs.MalaCards+1

In this condition, the main damage is to the axons, which are the long “wires” of the nerves, so it is grouped with axonal Charcot-Marie-Tooth diseases (CMT2). The specific subtype most often linked with the name “autosomal recessive axonal Charcot-Marie-Tooth disease with pyramidal features” is called Charcot-Marie-Tooth disease, axonal type 2H (CMT2H).MalaCards+1

The inheritance is autosomal recessive, which means a child usually becomes affected only when both parents carry a faulty copy of the disease gene and both pass it on. The disease usually begins in childhood, often in the first decade of life, and progresses slowly over many years.MalaCards+1

Clinically, children or young adults develop distal muscle wasting, weakness of the feet and lower legs, walking problems, high arched feet (pes cavus), and loss of feeling in the feet and hands. At the same time, they may show “pyramidal” signs such as brisk knee reflexes and mild stiffness, because the corticospinal (pyramidal) tracts are also involved.orpha.net+1

Because this condition is rare and overlaps with many other types of inherited neuropathy, doctors rely on a combination of clinical examination, nerve tests, and genetic testing to confirm the exact subtype. Correct naming is important for prognosis, family planning, and possible future treatments.NCBI+1

Other names

This disease has several other names in medical databases. All of them refer to the same or very closely related conditions and can appear in different articles or reports.MalaCards+1

Commonly used other names include:

• Charcot-Marie-Tooth disease, axonal, type 2H (CMT2H)

• Charcot-Marie-Tooth disease axonal type 2H

• Charcot-Marie-Tooth disease, type 2H (CMT2H / CMT4C2)

• Autosomal recessive axonal CMT with pyramidal involvement

• Axonal Charcot-Marie-Tooth disease with pyramidal involvement

• Autosomal recessive axonal Charcot-Marie-Tooth neuropathy with pyramidal features

These different labels reflect how the disease was first described in specific families, the chromosome region (8q21.3), and the pattern of nerve and pyramidal tract involvement.MalaCards+1

Types (clinical patterns)

There is only one formal genetic subtype named “CMT2H,” but in practice doctors often describe patterns of the disease rather than strict types. These patterns help to explain how the same basic disease can look slightly different from one person or family to another.Europe PMC+1

• Childhood-onset classic CMT2H pattern
  In this pattern, children develop weakness and wasting in the feet and lower legs in the first decade of life, with high-arched feet, ankle instability, and mild sensory loss. Pyramidal signs, such as brisk knee reflexes, are present but not very severe. Walking problems progress slowly over many years.orpha.net+1

• More pyramidal-dominant pattern
  Some patients show stronger signs of corticospinal (pyramidal) tract involvement, such as leg stiffness, increased muscle tone, or a slightly spastic gait, in addition to the peripheral neuropathy. In these people, the “upper motor neuron” features may appear earlier or be more obvious than in typical CMT.Practical Neurology+1

• Overlap pattern with other axonal CMT genes
  Mutations in several axonal CMT genes, such as GDAP1 or SPG11, can produce autosomal recessive axonal neuropathy with pyramidal signs that closely resemble CMT2H. Clinicians sometimes group these together as “autosomal recessive axonal CMT with pyramidal features,” even though the exact gene and locus may differ.MalaCards+2Europe PMC+2

These are descriptive clinical patterns, not official separate disease codes, but they help in counseling families and deciding which genes to test.ScienceDirect+1

Causes

1. Pathogenic variants at the CMT2H locus (8q21.3)
The original Tunisian family with this disorder showed linkage to a region on chromosome 8q21.3, called the CMT2H locus. A harmful genetic change in this region disrupts normal nerve function and leads to axonal sensorimotor neuropathy with pyramidal features.MalaCards+1

2. GDAP1 gene mutations
Changes in the GDAP1 gene can cause autosomal recessive axonal CMT (CMT2K and related forms) and may be associated with pyramidal signs in some patients. GDAP1 is involved in mitochondrial function in neurons, so its disruption weakens long peripheral axons.MalaCards+1

3. SPG11 (ALS5) gene mutations
Mutations in the SPG11 gene, usually known for hereditary spastic paraplegia, have also been shown to cause autosomal recessive axonal Charcot-Marie-Tooth disease with pyramidal signs. This explains why some patients show both peripheral neuropathy and strong corticospinal tract involvement.MalaCards+1

4. MORC2 gene mutations (related overlapping phenotype)
Pathogenic variants in MORC2 cause an axonal CMT subtype (CMT2Z) that often presents with pyramidal signs, such as spasticity and brisk reflexes. Although CMT2Z is often autosomal dominant, its biology illustrates how single-gene changes in axonal CMT can also affect central motor pathways.MalaCards+1

5. Other axonal CMT genes (MFN2, NEFL and others)
Several other genes that cause axonal CMT (for example MFN2, NEFL, GARS, DNM2) can, in rare families, be associated with upper motor neuron signs, creating a phenotype that overlaps with autosomal recessive axonal CMT with pyramidal involvement, even if the inheritance pattern is different.Europe PMC+1

6. Autosomal recessive inheritance pattern
The underlying cause at the family level is autosomal recessive inheritance: both parents carry one faulty copy of the gene but are usually healthy. When a child inherits two faulty copies, the disease appears. Consistent autosomal recessive transmission has been documented for CMT2H and related AR-axonal CMT syndromes.MalaCards+1

7. Consanguinity or marriage within a small gene pool
When parents are related, or come from a small, genetically isolated community, there is a higher chance that they share the same rare mutation. This increases the risk of autosomal recessive diseases such as CMT2H appearing in multiple siblings.orpha.net+1

8. Axonal “dying-back” degeneration of long nerves
The disease process mainly affects the long axons to the feet and hands. Metabolic and structural stress makes these long fibers gradually degenerate from the ends backward (“dying-back”), leading to distal weakness and sensory loss. This axonal pattern is typical of CMT2.NCBI+1

9. Mitochondrial dysfunction in neurons
Genes such as GDAP1 are important for mitochondrial dynamics in nerve cells. When these genes are mutated, mitochondria cannot maintain energy supply along the long axons. Over time, this lack of energy contributes to axonal degeneration and neuropathy.MalaCards+1

10. Oxidative stress vulnerability
Studies in cell models of GDAP1-related CMT suggest that nerve cells become more sensitive to oxidative stress, meaning they are more easily damaged by reactive oxygen species. This extra vulnerability may speed up the loss of peripheral axons.MalaCards+1

11. Disrupted axonal transport
Many CMT-related genes influence microtubules, mitochondria, or vesicle transport along the axon. When these processes fail, essential proteins and organelles cannot reach the nerve endings, which contributes to gradual axonal breakdown.Europe PMC+1

12. Subtle myelin support problems
Even though CMT2H is an axonal neuropathy, the interaction between axons and Schwann cells (myelin-forming cells) is important. Mild abnormalities in myelin support, secondary to the genetic defect, may worsen axonal stress and make nerves more fragile.Radiopaedia+1

13. Pyramidal tract susceptibility
For reasons that are not fully understood, the corticospinal (pyramidal) tracts can also be affected in this disease. The same gene defect or shared cellular pathways may damage upper motor neuron axons, leading to brisk reflexes and mild spasticity in some patients.MalaCards+1

14. Genetic modifiers affecting severity
Other genes and variants in the patient’s genome can act as “modifiers,” making the neuropathy and the pyramidal signs milder or more severe. This helps explain why even within the same family, some people are more disabled than others.Europe PMC+1

15. Random chance in which neurons are most affected
Even with the same mutation, random biological differences between nerve cells influence exactly how quickly they degenerate. This natural variability contributes to different patterns of weakness, balance problems, and pyramidal features between individuals.NCBI+1

16. Co-existing acquired neuropathy (e.g., diabetes)
If a person with this genetic disease also develops an acquired nerve problem, such as diabetic neuropathy or vitamin deficiency, the overall neuropathy can become more severe and symptoms appear earlier, even though the root cause remains genetic.NCBI+1

17. Co-existing spinal cord or brain lesions
Rarely, another condition affecting the spinal cord, such as mild cervical degeneration, may add extra pyramidal signs on top of the inherited neuropathy. This combined effect can make leg stiffness and brisk reflexes more prominent.Practical Neurology+1

18. Limited nerve regeneration capacity with age
As people age, axons regenerate less easily. In a person already carrying a harmful mutation, this limited repair ability means that damage accumulates and weakness slowly worsens over time.NCBI+1

19. Founder mutations in specific populations
The first description of CMT2H came from a large Tunisian family with a shared ancestral mutation. In such “founder” situations, a single mutation passed down through generations leads to many affected relatives in that region.MalaCards+1

20. Lack of disease-modifying treatment (currently)
At present, no proven disease-modifying drug exists to protect the axons in CMT, so the underlying genetic and cellular problems continue unchecked. Research into gene-targeted and mitochondrial-targeted therapies is ongoing but is still experimental.NCBI+1

Symptoms

1. Slowly progressive weakness in the feet and ankles
The earliest and most common symptom is weakness in the small muscles of the feet and ankles. Children may struggle to run, hop, or climb stairs. This happens because the longest motor axons are damaged first, so the muscles they supply become weak.NCBI+1

2. Distal muscle wasting (“thin calves” and small feet muscles)
As the disease continues, the muscles in the lower legs and feet shrink and look wasted, sometimes giving a “stork leg” appearance with thin calves. This is a direct result of chronic denervation from the axonal neuropathy.NCBI+1

3. High-arched feet (pes cavus)
Many affected people develop high-arched feet, often with clawed or hammer toes. This fixed foot deformity is caused by long-term imbalance between weak and stronger muscles in the feet, and it is a classic sign of inherited neuropathies such as CMT.NCBI+1

4. Frequent tripping and falls
Drop-foot (difficulty lifting the front of the foot) and poor ankle control make the toes drag on the ground. Patients often trip on small obstacles or uneven surfaces and may fall, especially when tired or walking fast.NCBI+1

5. Weakness in the hands and fingers
With time, weakness may spread to the hands, causing difficulty doing up buttons, writing for long periods, or holding small objects. This reflects the spread of axonal degeneration to the nerves of the upper limbs.NCBI+1

6. Numbness or tingling in the feet
Damage to sensory axons causes reduced feeling, pins and needles, or burning sensations in the feet and, later, in the hands. Loss of protective sensation increases the risk of unnoticed skin injuries and pressure sores.NCBI+1

7. Reduced vibration and position sense
People often lose the ability to sense vibration from a tuning fork or to know exactly where their joints are without looking. This “proprioceptive” loss contributes to poor balance and difficulty walking on uneven ground or in the dark.NCBI+1

8. Absent or reduced ankle reflexes
On examination, ankle jerks are usually absent because the distal part of the reflex arc is damaged. This is very typical for length-dependent peripheral neuropathy and helps distinguish CMT from pure upper motor neuron disorders.orpha.net+1

9. Brisk knee and upper-limb reflexes (pyramidal sign)
Despite absent ankle reflexes, the knee and sometimes upper-limb reflexes can be brisk, and a doctor may see a pyramidal pattern of reflexes. This combination—distal neuropathy with brisk more-proximal reflexes—is a hallmark of CMT with pyramidal involvement.orpha.net+1

10. Mild spasticity or stiffness in the legs
Some patients show increased muscle tone and mild spasticity in the legs. The gait may look slightly stiff or scissoring. This reflects involvement of the corticospinal (pyramidal) tracts in addition to the peripheral nerves.MalaCards+1

11. Gait imbalance and difficulty with tandem walking
Because of weakness, sensory loss, and pyramidal signs, patients often struggle to walk in a straight line or to balance on narrow surfaces. Tandem gait (heel-to-toe walking) is especially hard and is commonly abnormal in clinical examination.Orphan Anesthesia+1

12. Fatigue and reduced endurance in the legs
Walking long distances, standing for a long time, or climbing stairs can cause heavy fatigue and aching in the legs. Muscles have to work harder to compensate for weakness, deformity, and inefficient gait patterns.NCBI+1

13. Foot and ankle pain
Joint stress from abnormal foot posture and tight tendons can cause pain in the feet, ankles, and sometimes the knees. This pain is often mechanical but can also be neuropathic (burning or shooting).NCBI+1

14. Hand clumsiness and difficulty with fine tasks
When hand muscles become weak and sensory feedback is reduced, tasks like typing, fastening jewelry, or drawing become slow and clumsy. This loss of fine motor control can affect schoolwork and daily activities.NCBI+1

15. Mild postural changes or scoliosis
Over many years, muscle imbalance and foot deformities may alter posture and contribute to mild scoliosis or curvature of the spine in some patients, though this is not universal.NCBI+1

Diagnostic tests

Doctors use a combination of physical examination, manual bedside tests, laboratory and pathological studies, electrodiagnostic tests, and imaging to diagnose this disease and to distinguish it from other neuropathies or pure spastic disorders.NCBI+1

Physical examination tests

1. Full neurological examination
The neurologist carefully checks muscle bulk, strength, reflexes, tone, and all sensory modes in the arms and legs. The key pattern is distal wasting and weakness, absent ankle reflexes, sensory loss in a stocking-glove pattern, and relatively brisk knee reflexes, suggesting both peripheral and pyramidal involvement.NCBI+1

2. Gait and posture assessment
The doctor watches the patient walking normally, on heels and toes, and turning quickly. They look for foot drop, high-stepping or slapping gait, and signs of spasticity. This visual assessment helps document the combination of neuropathic and pyramidal gait features.Orphan Anesthesia+1

3. Deep tendon reflex testing
Reflexes at the ankles, knees, biceps, and triceps are tested using a reflex hammer. In autosomal recessive axonal CMT with pyramidal features, ankle reflexes are often absent, while knee and sometimes upper-limb reflexes are exaggerated, revealing the mixed involvement.orpha.net+1

4. Muscle tone and spasticity evaluation
The examiner gently moves the patient’s legs and arms to feel for increased resistance that suddenly gives way (a spastic “catch”). Mild spasticity in the legs, together with distal weakness, supports pyramidal involvement rather than pure peripheral neuropathy alone.Practical Neurology+1

5. Sensory examination
Light touch, pinprick, vibration (with a tuning fork), and joint position sense are checked in a distal-to-proximal pattern. Reduced sensation in the feet, especially vibration and joint position, is typical and helps confirm the axonal sensorimotor neuropathy.NCBI+1

Manual bedside tests

6. Manual muscle strength testing (MRC scale)
The clinician grades muscle strength in specific groups, such as ankle dorsiflexors, toe extensors, and finger abductors, using a standard 0–5 scale. Distal weakness with relatively preserved proximal strength supports a length-dependent inherited neuropathy.NCBI+1

7. Heel-walking test
The patient is asked to walk on their heels. Difficulty or inability to keep the toes off the ground suggests significant weakness of ankle dorsiflexors (foot-lifting muscles), a common early sign in CMT.NCBI+1

8. Toe-walking test
Walking on toes checks the strength of the calf muscles. Some patients with axonal CMT have relative weakness in toe walking as the disease progresses, and this is recorded in the exam to track severity over time.NCBI+1

9. Romberg balance test
The patient stands with feet together, first with eyes open, then with eyes closed. Worsening sway or loss of balance with eyes closed indicates impaired proprioception from sensory nerve damage, which is common in CMT.Orphan Anesthesia+1

10. Tandem gait (heel-to-toe walking)
The person walks in a straight line placing one foot directly in front of the other. Difficulty or stepping out of line indicates impaired balance from combined weakness, sensory loss, and pyramidal signs, and is often abnormal in this condition.Orphan Anesthesia+1

Laboratory and pathological tests

11. Basic blood tests to exclude acquired causes
Blood tests such as full blood count, vitamin B12, thyroid function, and glucose are often done to rule out common acquired neuropathies. In CMT2H these tests are usually normal, which supports a hereditary cause but does not prove it.NCBI+1

12. Serum creatine kinase (CK)
Some patients with inherited neuropathies have mildly raised CK due to ongoing muscle denervation and re-innervation. A normal or slightly raised CK can be seen in axonal CMT and may help exclude primary muscle disease.Europe PMC+1

13. Nerve biopsy (sural nerve)
In selected cases, a small sensory nerve near the ankle (sural nerve) is removed and examined under the microscope. In axonal CMT, biopsy usually shows loss of myelinated fibers with relatively preserved myelin thickness, confirming axonal neuropathy rather than demyelinating disease.Wikipedia+1

14. CMT gene panel testing
Modern diagnostic practice uses multigene panels that test many known CMT genes at once. When a pathogenic variant at the CMT2H locus, GDAP1, SPG11, or another relevant gene is found, it provides a precise genetic diagnosis and confirms the autosomal recessive inheritance.ARUP Consult+1

15. Expanded or exome sequencing
If a standard panel is negative but the clinical picture strongly suggests inherited neuropathy with pyramidal features, whole-exome or whole-genome sequencing can be used to search for rarer or novel mutations, including variants linked to CMT2H-like phenotypes.Europe PMC+1

Electrodiagnostic tests

16. Nerve conduction studies (NCS)
NCS measure the speed and size of electrical signals along the nerves. In axonal CMT, conduction velocities are often normal or only mildly slowed, but the response amplitudes are reduced, reflecting loss of axons. This pattern supports a diagnosis of CMT2 rather than demyelinating CMT1.NCBI+1

17. Needle electromyography (EMG)
EMG looks at electrical activity in muscles. In CMT2H, EMG often shows signs of chronic denervation and re-innervation in distal muscles, confirming that weakness comes from nerve problems rather than primary muscle disease.Wikipedia+1

18. Somatosensory evoked potentials (SSEPs)
In some centers, SSEPs are used to test the integrity of sensory pathways from the limbs up through the spinal cord to the brain. Delayed central responses can provide additional evidence of pyramidal or central pathway involvement in addition to the peripheral neuropathy.Practical Neurology+1

Imaging tests

19. MRI of the brain and spinal cord
Magnetic resonance imaging may be performed to exclude other causes of pyramidal signs, such as multiple sclerosis or structural spinal cord lesions. In some patients with CMT and pyramidal features, subtle corticospinal tract changes may be seen, but MRI can also be normal.Practical Neurology+1

20. Foot and ankle X-rays or other musculoskeletal imaging
X-rays of the feet and ankles show fixed deformities such as pes cavus, claw toes, and joint instability. Documenting these changes helps orthopedic planning and supports the diagnosis of long-standing neuropathic foot deformity due to CMT.NCBI+1

Non-pharmacological treatments

1. Physiotherapy strengthening exercises
   A physiotherapist teaches gentle, regular exercises for the legs, arms and trunk to keep muscles as strong as possible without over-tiring them. The purpose is to slow muscle wasting, maintain movement and improve walking. The main mechanism is repeated, low-impact muscle activation, which helps preserve remaining nerve-muscle connections and prevents joints from becoming stiff. Evidence from CMT rehabilitation reviews shows physiotherapy is a central part of management. MDPI+3Physiopedia+3ScienceDirect+3

2. Stretching and contracture prevention
   Daily stretching of calves, hamstrings, hips and hand muscles helps keep joints straight and flexible. The purpose is to prevent contractures, where muscles shorten and joints become fixed in a bent position. The mechanism is simple: regular stretching lengthens muscle fibres and soft tissue, reducing the pull that causes deformity over time. Physiotherapy guidelines for CMT recommend early stretching for feet and ankles to limit deformity. nhs.uk+2Pod NMD+2

3. Balance and gait training
   Special balance exercises, such as standing on different surfaces, tandem walking or using balance boards, can improve stability and reduce falls. The purpose is to train the brain and remaining sensory pathways to better sense body position (proprioception). The mechanism is repeated practice of balance tasks, which helps the nervous system adapt and compensate for lost sensation in the feet. CMT studies show that targeted gait and balance programmes can improve walking safety. ScienceDirect+2www.elsevier.com+2

4. Occupational therapy for daily activities
   An occupational therapist teaches easier ways to dress, write, cook and manage personal care, sometimes using adapted tools (for example, built-up pens or special cutlery). The purpose is to keep the person independent at home, school or work. The mechanism is changing the environment and tools so that weaker muscles and poor sensation cause fewer problems in everyday tasks. NCBI+2PM&R KnowledgeNow+2

5. Ankle-foot orthoses (AFOs)
   AFO braces support weak ankles and help lift the toes during walking so the person does not trip. The purpose is to improve walking pattern, prevent falls and slow foot deformity. The mechanism is external support: the brace holds the ankle in a more normal position and replaces some lost muscle power. Clinical resources for CMT show that flexible AFOs are often helpful for foot drop. Pod NMD+3ScienceDirect+3Charcot-Marie-Tooth Association+3

6. Custom shoe inserts and supportive footwear
   Soft insoles, arch supports and extra-depth shoes can spread pressure under the foot and support high arches (pes cavus). The purpose is to reduce pain, prevent skin damage and improve balance. The mechanism is pressure redistribution and stabilisation of the foot shape so that walking feels more secure and less painful. Reviews of foot orthoses in CMT show improved foot function and less pain in many patients. www.elsevier.com+2Pod NMD+2

7. Hand splints and fine-motor aids
   Lightweight splints for wrists and fingers can support weak hand muscles, while tools like jar openers, button hooks and special keyboards reduce strain. The purpose is to keep hand function for writing, typing and self-care. The mechanism is mechanical support of joints plus task simplification so weak muscles do not have to work as hard. NCBI+1

8. Mobility aids (cane, walker, wheelchair)
   Using a cane or walker at the right time can prevent serious falls and injuries. Some people later need a wheelchair for long distances. The purpose is safety and energy saving, not giving up. The mechanism is sharing the load between the body and the device so that weak muscles and bad balance cause less risk and fatigue. Muscular Dystrophy Association+1

9. Home and school fall-prevention changes
   Simple changes like removing loose rugs, adding grab bars in bathrooms, improving lighting and arranging classrooms or desks for easier access can greatly cut the chance of falls. The purpose is to make the environment match the person’s balance and strength. The mechanism is hazard reduction: fewer tripping and slipping risks mean fewer accidents even when the nerves are weak. www.elsevier.com+1

10. Speech and swallowing therapy (if needed)
    If pyramidal features affect bulbar muscles, a speech-language therapist can help with swallowing strategies and safe eating positions, and may train clearer speech. The purpose is to avoid choking, weight loss and communication problems. The mechanism is teaching specific movements and compensations that help weak or stiff muscles work more safely. NCBI+1

11. Respiratory physiotherapy (in advanced cases)
    In rare, more severe cases where breathing muscles weaken, respiratory therapists can teach breathing exercises, coughing techniques and sometimes non-invasive ventilation. The purpose is to maintain lung function and reduce chest infections. The mechanism is assisting weakened respiratory muscles and keeping airways clear. NCBI+1

12. Pain psychology and cognitive behavioural therapy (CBT)
    Long-term neuropathic pain and disability can cause stress, low mood and anxiety. A psychologist using CBT can teach coping skills, relaxation and pacing. The purpose is to reduce suffering and improve quality of life even if some pain remains. The mechanism is changing thoughts and behaviours around pain to lower its impact on daily life. U.S. Food and Drug Administration+1

13. Energy conservation and fatigue management
    Learning to plan the day, rest between tasks, sit instead of stand and use tools that save effort helps manage fatigue. The purpose is to make energy last longer so study, work and family life are still possible. The mechanism is balancing activity and rest to prevent “over-doing it” that worsens weakness and tiredness. Muscular Dystrophy Association+1

14. Sleep hygiene and management of sleep problems
    Some people with CMT have sleep issues, sometimes related to pain, muscle cramps or restless legs. Good sleep habits—regular bedtime, low screen use before sleep, quiet dark rooms—plus treatment of pain or cramps can help. The purpose is deeper, more refreshing sleep. Better sleep improves mood, energy and pain tolerance. NCBI+1

15. Nutritional counselling
    A dietitian can design a balanced diet to maintain healthy weight, support muscles and avoid constipation. The purpose is to give the body the best chance to cope with weakness and limited mobility. The mechanism is steady supply of protein, vitamins and minerals that nerves and muscles need, while avoiding excess weight that makes movement harder. Charcot-Marie-Tooth Association+1

16. Patient and family education
    Clear explanations about the disease, inheritance pattern and realistic expectations help families feel more in control. The purpose is to reduce fear and confusion and support shared decision-making. The mechanism is knowledge: understanding what is happening and why makes it easier to follow treatment plans and notice warning signs early. www.elsevier.com+1

17. Genetic counselling
    Because this condition is autosomal recessive, genetic counselling can explain carrier risk, options for future pregnancies and testing of other family members if appropriate. The purpose is informed family planning and early detection. The mechanism is using genetic information to estimate the chance of affected or carrier children and to discuss possible choices in a sensitive way. Charcot-Marie-Tooth Association+1

18. School and vocational support
    Educational and workplace adjustments—extra time for exams, ergonomic chairs, flexible schedules or remote work—can keep people in school and jobs. The purpose is full social participation despite disability. The mechanism is changing the demands of the environment rather than expecting the person’s body to do more than it can. U.S. Food and Drug Administration+1

19. Peer support groups and patient organisations
    National CMT associations and online communities let people share experiences, tips and emotional support. The purpose is to reduce isolation and give real-world advice from others living with the same condition. The mechanism is social connection and shared problem-solving, which can improve mental health and motivation. Charcot-Marie-Tooth Disease+1

20. Regular follow-up in a neuromuscular clinic
    Scheduled visits with specialists help track progression, update braces and exercises, and adjust treatment for pain, spasticity or mood. The purpose is early detection of new problems and ongoing optimisation of care. The mechanism is continuous monitoring plus timely changes in the care plan based on current needs, as recommended in modern CMT guidelines. Ciència i Salut+2www.elsevier.com+2

Drug treatments

⚠️ Because you are a minor, it is very important not to start, stop or change any medicine based on online information. All of the medicines below require a doctor’s decision and follow-up. Doses are individual, so only your own doctor can decide what is safe for you.

1. Gabapentin
   Gabapentin is an anticonvulsant medicine that is widely used to treat neuropathic pain, such as burning, shooting or electric-shock pain in damaged nerves. It works by changing how certain calcium channels in nerve cells release excitatory transmitters, which can calm over-active pain pathways. The FDA label for Neurontin notes its role in neuropathic pain syndromes, though it is not specific to CMT. FDA Access Data+2FDA Access Data+2

2. Pregabalin
   Pregabalin is related to gabapentin and is approved by the FDA for neuropathic pain in conditions like diabetic nerve damage and spinal cord injury. It binds to the α2δ subunit of voltage-gated calcium channels, reducing release of pain-signalling chemicals. In CMT, doctors may use it off-label to ease nerve pain and improve sleep. The dose is carefully increased and adjusted based on effect and side effects. FDA Access Data+3FDA Access Data+3FDA Access Data+3

3. Duloxetine
   Duloxetine is a serotonin-noradrenaline reuptake inhibitor (SNRI) approved for diabetic peripheral neuropathic pain and fibromyalgia. It increases levels of these neurotransmitters in brain and spinal cord pain pathways, which can dampen pain signals and also improve mood. For people with CMT and significant pain plus low mood or anxiety, specialists sometimes consider duloxetine after careful review of risks, including nausea and sleep changes. FDA Access Data+3FDA Access Data+3FDA Access Data+3

4. Amitriptyline
   Amitriptyline is a tricyclic antidepressant often used in small doses for nerve pain and poor sleep. It blocks reuptake of serotonin and noradrenaline and also acts on other receptors that modulate pain. In people with CMT, it may reduce burning or tingling sensations and help with falling asleep, but it can cause dry mouth, dizziness and daytime drowsiness, so it must be started and adjusted carefully by a doctor. ScienceDirect+1

5. Carbamazepine or oxcarbazepine
   These anticonvulsants can be used in some types of nerve pain and muscle spasms. They work by stabilising sodium channels in nerve membranes, reducing abnormal firing. In CMT with pyramidal features, where spasticity or painful spasms occur, a neurologist may consider these drugs, but they require blood tests and monitoring because of possible side effects such as low sodium or allergic reactions. ScienceDirect+1

6. Baclofen (oral)
   Baclofen is a muscle relaxant that acts on GABA-B receptors in the spinal cord to reduce spasticity. In autosomal recessive axonal CMT with pyramidal features, increased muscle tone and stiffness may be helped by baclofen under specialist supervision. An oral combination including baclofen, naltrexone and sorbitol has even received FDA orphan designation for CMT1A, showing ongoing research interest, although it is not yet an approved treatment for CMT. FDA Access Data+2ScienceDirect+2

7. Tizanidine
   Tizanidine is another antispastic medicine that works as an α2-adrenergic agonist in the central nervous system, reducing the release of excitatory transmitters that cause muscle tone to increase. In people with pyramidal signs, it can ease stiffness and improve movement, but it may cause sleepiness and low blood pressure, so doctors adjust the dose slowly and check liver function. www.elsevier.com+1

8. Botulinum toxin injections
   For very focal spasticity or muscle over-activity, such as in specific calf or thigh muscles, botulinum toxin can be injected into the muscles. It blocks acetylcholine release at the neuromuscular junction, temporarily weakening the over-active muscle and improving posture or gait. The effect lasts a few months and must be done by trained specialists, often together with physiotherapy and bracing. www.elsevier.com+1

9. Non-steroidal anti-inflammatory drugs (NSAIDs)
   Medicines like ibuprofen or naproxen are used for general musculoskeletal pain, joint strain and headaches. They work by blocking cyclo-oxygenase enzymes, which reduces inflammatory prostaglandins. In CMT, they do not fix nerve damage but may ease pain after over-use or minor injuries. They can irritate the stomach or kidneys, so doses and duration must follow doctor or pharmacist advice, especially in young people. Muscular Dystrophy Association+1

10. Paracetamol (acetaminophen)
    Paracetamol is widely used for mild to moderate pain and fever. It likely acts both in the brain and spinal cord on prostaglandin pathways, but its exact mechanism is not fully understood. For people with CMT, it can be part of a simple pain plan for mild discomfort, but total daily dose must stay within safety limits to protect the liver, and medical advice is essential if pain is frequent. Muscular Dystrophy Association+1

11. Topical lidocaine patches or gels
    Lidocaine patches placed on painful areas can reduce local nerve firing by blocking sodium channels in skin nerves. The purpose is to relieve focal neuropathic pain without causing many body-wide side effects. This can be helpful when pain is limited to certain spots on the feet or legs. Doctors check skin condition and other medications before recommending this option. ScienceDirect+1

12. Topical capsaicin cream
    Capsaicin cream, made from chilli pepper extract, can reduce pain after repeated use by depleting substance P and desensitising certain pain fibres. For some people with nerve pain from CMT, it may reduce burning sensations, but it can cause local burning or redness at first. It must be applied exactly as instructed and kept away from eyes and mucous membranes. ScienceDirect+1

13. Selective serotonin reuptake inhibitors (SSRIs)
    Medicines like sertraline or citalopram can treat depression and anxiety, which are common in chronic neurological illness. They increase serotonin in the brain, which helps mood and sometimes improves pain coping. In CMT, treating depression can make it easier to stay active in therapy and manage symptoms, but SSRIs must be chosen and monitored by a doctor, especially in teenagers. U.S. Food and Drug Administration+1

14. Other SNRIs (for example venlafaxine)
    Like duloxetine, venlafaxine increases serotonin and noradrenaline and can be used for anxiety, depression and sometimes neuropathic pain. In carefully selected patients, it may help when other options fail, but it can raise blood pressure and cause withdrawal symptoms if stopped suddenly. It should only be used under close medical supervision. FDA Access Data+1

15. Magnesium supplements (for cramps, when deficient)
    Magnesium is not a specific drug for CMT, but if blood tests show low magnesium and the person has cramps, supplements may be used. Magnesium helps regulate muscle contraction and nerve signalling. When levels are corrected, cramps may improve. However, too much magnesium can upset the stomach or affect the heart, so doses must follow medical advice. Charcot-Marie-Tooth Association+1

16. Vitamin D and calcium (if low)
    Weak mobility and indoor life can lead to low vitamin D and weaker bones. Supplementing vitamin D and calcium when blood tests show deficiency can strengthen bones and reduce fracture risk in falls. The mechanism is improved calcium absorption and bone mineralisation. These are general health measures, not specific CMT drugs, but they are important in long-term nerve disease. Charcot-Marie-Tooth Association+1

17. Laxatives or stool softeners (for constipation)
    Reduced mobility and some drugs can cause constipation. Mild laxatives or stool softeners may be used short term to keep bowel movements regular. The mechanism is softening stool or stimulating bowel movement. This supports comfort and quality of life but must be combined with fluids, fibre and medical advice. Muscular Dystrophy Association+1

18. Melatonin (sleep regulation, under supervision)
    Melatonin is a hormone that helps regulate sleep-wake cycles. In some neurological conditions, short-term melatonin can be used to improve sleep onset. Better sleep can reduce daytime fatigue and pain sensitivity. For young people, doses must be low and supervised by a doctor because long-term effects are still being studied. NCBI+1

19. Medications for associated conditions (for example anti-epileptics, if seizures)
    If the individual also has seizures or other neurological problems, standard anti-seizure drugs may be prescribed according to guidelines. These medicines work by stabilising abnormal brain activity and are chosen based on seizure type, age and other medicines. They are not specific to CMT but treat co-existing conditions that might worsen overall function. NCBI+1

20. Clinical-trial medicines (investigational)
    Some experimental medicines, such as metabolic modulators, neuromuscular junction enhancers or gene-targeted drugs, are being tested in clinical trials for different types of CMT. Examples include investigational drugs like NMD670 and govorestat (AT-007) in specific CMT subtypes, but they are not yet approved or proven for axonal CMT with pyramidal features. Participation in trials is only through specialist centres and strict protocols. Charcot-Marie-Tooth Disease+3NMD Pharma+3ClinicalTrials.gov+3

Dietary molecular supplements

These supplements are not cures, and evidence in CMT is limited. They should only be used under medical supervision, especially in young people.

1. Vitamin B1 (thiamine) – supports carbohydrate metabolism and energy production in neurons; deficiency can worsen neuropathy.

2. Vitamin B6 (pyridoxine, in safe doses) – helps with neurotransmitter synthesis; both deficiency and excess can damage nerves, so dosing must be careful.

3. Vitamin B12 (cobalamin) – important for myelin and DNA synthesis; correcting deficiency can improve nerve function in some people. Charcot-Marie-Tooth Association+1

4. Folate (vitamin B9) – works with B12 in DNA and red-blood-cell production; low levels can worsen fatigue and overall health.

5. Vitamin D – supports bone and muscle health; low levels are common in people with limited mobility and should be corrected.

6. Vitamin E – an antioxidant that protects cell membranes; severe deficiency can cause neuropathy, so replacing low levels may be helpful.

7. Alpha-lipoic acid – an antioxidant used in some neuropathy studies; it may reduce oxidative stress in nerves, though evidence in CMT is still limited. Charcot-Marie-Tooth Association+1

8. Omega-3 fatty acids (fish oil) – support cell membranes and may have mild anti-inflammatory effects, which can help general cardiovascular and nerve health.

9. Coenzyme Q10 – part of mitochondrial energy production; some small studies suggest benefits in certain neuromuscular diseases, but data in CMT are sparse.

10. L-carnitine – helps transport fatty acids into mitochondria for energy; sometimes used in metabolic and muscle disorders under specialist guidance. Charcot-Marie-Tooth Association+1

Immunity-booster, regenerative and stem-cell-related drugs

1. Gene therapy approaches
   Research is exploring gene therapy for some CMT subtypes, such as AAV9-based gene therapy for CMT4J. These strategies aim to deliver a normal copy of a faulty gene to nerve cells. At present, such treatments are experimental, with orphan designation but no full approval, and are only available in clinical trials. FDA Access Data+2ClinicalTrials.gov+2

2. siRNA-based therapies
   For CMT1A, small interfering RNA (siRNA) therapies targeting PMP22 over-expression have been granted orphan designation. The mechanism is lowering the level of a protein that is too high and damages myelin. These treatments are still under investigation and are not standard care for any CMT type yet. FDA Access Data+1

3. Neuromuscular junction modulators (for example NMD670)
   NMD670 has received orphan drug designation for CMT and is designed to enhance neuromuscular junction function, aiming to improve muscle strength. Its mechanism is to increase the safety margin of nerve-muscle transmission. It is being studied in adults under trial conditions and is not yet approved. NMD Pharma+1

4. Metabolic modulators (for example govorestat in CMT-SORD)
   Govorestat (AT-007) is being developed for CMT-SORD, a different hereditary neuropathy. It aims to reduce toxic sorbitol levels. While not directly for axonal CMT with pyramidal features, it shows how targeted metabolic drugs may help specific genetic forms in the future. Charcot-Marie-Tooth Association+1

5. Cell-based therapies (stem-cell approaches)
   Various stem-cell strategies are being explored in laboratories and small studies, such as using mesenchymal stem cells or Schwann-cell-related cells to support or repair nerves. However, there is currently no approved stem-cell therapy for CMT, and unregulated clinics can be risky. Any consideration must be through properly controlled clinical trials only. U.S. Food and Drug Administration+1

6. Immune-modulating treatments (only in special cases)
   If a person with CMT also has an autoimmune condition affecting nerves, doctors may use steroids or other immunosuppressants. These drugs suppress abnormal immune attacks but can weaken infection resistance. They are not standard for genetic axonal CMT by itself and are only used when another immune disease is clearly present. PM&R KnowledgeNow+1

Surgeries

1. Foot deformity correction (osteotomy and soft-tissue release)
   In people with severe high arches, claw toes and unstable ankles, orthopedic surgeons may cut and realign bones (osteotomy) and release tight tendons to improve foot shape. The purpose is to create a flatter, more stable foot for walking. This can reduce pain and improve shoe fitting in CMT. www.elsevier.com+2Pod NMD+2

2. Tendon transfer surgery
   Surgeons can move a working tendon (for example from a stronger muscle) to take over the function of a very weak muscle, such as lifting the foot. The purpose is to improve specific movements like toe-lift and reduce tripping. The mechanism is re-routing muscle force to a more useful position, which can make walking safer. ScienceDirect+1

3. Achilles tendon lengthening
   If the calf muscle and Achilles tendon become very tight, the ankle may not flex upwards enough. Lengthening the tendon surgically can restore a more neutral ankle position. The purpose is to make walking more natural and allow better brace fitting. The mechanism is releasing a fixed contracture so the foot can move through a normal range. Pod NMD+1

4. Joint fusion (arthrodesis) for severe deformity
   When joints are badly deformed and unstable, fusing them into a stable position can reduce pain and prevent further collapse. The purpose is not to restore normal motion but to create a solid, pain-reduced base for standing and walking. Surgeons consider this only after other options are discussed and in older teens or adults. www.elsevier.com+1

5. Spinal surgery (if significant scoliosis)
   In some neuromuscular diseases, severe spinal curvature develops. If this happens and causes pain, breathing problems or sitting difficulty, spinal surgery may be offered. Metal rods and screws straighten and stabilise the spine. This is a major operation, used only in selected cases after careful risk-benefit discussion. www.elsevier.com+1

Preventions

You cannot prevent the genetic mutation that causes this disease, but you can help prevent complications:

1. Early diagnosis and regular follow-up with a neuromuscular team.

2. Avoiding known nerve-toxic medicines such as vincristine, which has strong evidence for harm in CMT. PM&R KnowledgeNow

3. Wearing appropriate braces and shoes to prevent falls and joint injury.

4. Doing regular physiotherapy and stretching to reduce contractures and maintain strength. PMC+1

5. Protecting the feet—daily checks for cuts, blisters or pressure areas, especially when sensation is reduced.

6. Maintaining healthy body weight to reduce stress on weak muscles and joints. Muscular Dystrophy Association+1

7. Avoiding smoking and vaping, which harm blood vessels and nerves.

8. Controlling other conditions like diabetes that can cause extra nerve damage. Charcot-Marie-Tooth Association+1

9. Keeping vaccinations up to date, including flu and pneumonia shots if advised, to reduce serious infections that can worsen weakness.

10. Seeking genetic counselling before future pregnancies in the family to understand risks and options. Charcot-Marie-Tooth Association+1

When to see doctors

You should see a doctor or neuromuscular specialist regularly for routine reviews, but extra visits are needed if you notice new or rapid changes. These include: suddenly worse weakness, more frequent falls, new severe pain, marked increase in stiffness, changes in walking pattern, problems with swallowing or speaking, shortness of breath, chest infections that do not settle, new bladder or bowel control problems, or strong sadness, anxiety or thoughts of self-harm. Any sudden difficulty breathing, chest pain, or trouble staying awake is an emergency and needs urgent medical help. Regular contact with your care team allows early adjustments of braces, therapies and medicines. Ciència i Salut+2www.elsevier.com+2

What to eat and what to avoid

1. Eat: Plenty of colourful fruits and vegetables for vitamins, minerals and antioxidants that support general nerve and muscle health.

2. Eat: Adequate protein from fish, eggs, beans, dairy or lean meat to help maintain muscles.

3. Eat: Whole grains like brown rice, oats and whole-wheat bread for steady energy and fibre, which also prevents constipation. Charcot-Marie-Tooth Association+1

4. Eat: Foods rich in omega-3 fats, such as oily fish, walnuts and flaxseeds, which may support cell membranes and reduce inflammation.

5. Eat: Enough fluids (mainly water) throughout the day to help bowel function and overall health.

6. Avoid / limit: Highly processed foods high in trans fats, deep-fried snacks and fast food, which can harm heart and nerve health.

7. Avoid / limit: Sugary drinks and sweets that cause weight gain and can increase the risk of diabetes and extra nerve damage.

8. Avoid / limit: Very high salt foods that may worsen blood pressure and heart strain. Charcot-Marie-Tooth Association+1

9. Avoid: Crash diets or extreme low-calorie plans that lead to muscle loss, which is especially harmful in a muscle-weakening disease.

10. Avoid: Alcohol and recreational drugs; as a minor you should not use them at all, and they can worsen balance, nerve damage and medicine side effects. Charcot-Marie-Tooth Association+1

Frequently asked questions

1. Is this disease curable?
   Right now there is no cure for autosomal recessive axonal Charcot-Marie-Tooth disease with pyramidal features. Treatment focuses on managing symptoms, keeping you mobile and preventing complications while research continues into gene- and drug-based therapies. ScienceDirect+2www.elsevier.com+2

2. Will every child in the family get it?
   Because this is an autosomal recessive condition, parents are usually healthy carriers. Each child of two carriers has a 25% chance of being affected, a 50% chance of being a carrier and a 25% chance of inheriting no faulty copies. Genetic counselling can explain the risks for your specific family. Charcot-Marie-Tooth Association+1

3. Does it shorten life expectancy?
   Many people with CMT have a near-normal life span, especially when complications are prevented and other health conditions are well managed. However, severe weakness, falls or breathing problems can increase health risks, so careful follow-up and healthy habits are important. www.elsevier.com+2Muscular Dystrophy Association+2

4. Can exercise make the disease worse?
   Heavy, exhausting exercise that causes repeated injury is not good, but gentle, regular physiotherapy and low-impact activities like swimming or cycling are helpful. They maintain strength, flexibility and heart health without over-straining weak muscles. Your physiotherapist can design a safe programme. Physiopedia+2PMC+2

5. Can I go to normal school or work?
   Yes, most people with CMT can attend usual schools and workplaces with reasonable adjustments, such as extra time, accessible classrooms, ergonomic chairs or flexible hours. Early planning with teachers or employers and the rehabilitation team is key. PM&R KnowledgeNow+2www.elsevier.com+2

6. Is this the same as ALS?
   No. CMT is mainly a peripheral nerve disease that usually progresses more slowly and typically spares breathing and swallowing for many years. ALS is a different motor neuron disease with faster progression and different patterns. Some gene names overlap, but the conditions are distinct. NCBI+2OUP Academic+2

7. Will I need surgery for my feet or spine?
   Not everyone needs surgery. Many people do well with braces, physiotherapy and good shoes. Surgery is considered if deformities cause pain, frequent falls or trouble fitting braces. Decisions are made by you, your family and an orthopedic surgeon after careful evaluation. www.elsevier.com+2Pod NMD+2

8. Is stem-cell treatment a cure now?
   No. Stem-cell treatments for CMT are still experimental, and there is no approved stem-cell cure. Some private clinics offer expensive, unproven procedures that may be risky. Always discuss any proposed treatment with your neuromuscular specialist before considering it. Charcot-Marie-Tooth Disease+2ClinicalTrials.gov+2

9. Are there clinical trials I can join?
   There are clinical trials for some CMT subtypes, testing gene therapies, metabolic drugs and neuromuscular junction modulators. Eligibility depends on age, genetic subtype and disease stage. Your neurologist can help you search sites like ClinicalTrials.gov and national CMT organisations. Charcot-Marie-Tooth Association+3ClinicalTrials.gov+3Charcot-Marie-Tooth Disease+3

10. How can I manage pain day to day?
    Pain can be reduced with a mix of medicines, physiotherapy, stretching, comfortable shoes, rest breaks, heat or cold packs and relaxation techniques. Keeping a pain diary can help your doctor adjust treatment. It often takes time to find the best combination for you. ScienceDirect+2PMC+2

11. Will my condition always get worse?
    CMT is usually slowly progressive, but the speed and pattern vary. Some people have long stable periods. Early and consistent use of therapies, braces and healthy lifestyle habits can slow complications and keep function for many years. www.elsevier.com+2PM&R KnowledgeNow+2

12. Can I have a family in the future?
    Many people with CMT have children. Before planning a family, genetic counselling can help you understand risks and options such as partner testing or prenatal / pre-implantation genetic diagnosis, depending on local laws and resources. Charcot-Marie-Tooth Association+2pfmjournal.org+2

13. Does this disease affect intelligence?
    In most forms of CMT, including axonal types, thinking and intelligence are normal. Pyramidal features mean motor pathways are also affected, but this usually relates to movement, not learning or memory. Any learning difficulties should still be assessed separately. OUP Academic+2pfmjournal.org+2

14. How often should I see my specialists?
    The schedule depends on age and severity, but many people are seen every 6–12 months, with extra visits when changes occur. Children and teenagers may need more frequent reviews during growth spurts to adjust braces and monitor posture. Ciència i Salut+2www.elsevier.com+2

15. What can my family do to support me?
    Family can help by learning about the disease, encouraging safe exercise, helping with appointments, listening to worries and supporting school or work plans. They should also watch for signs of low mood or big changes in function and help you get timely medical advice. Support for caregivers is also important, as CMT is a long-term condition.
