Axonal Charcot-Marie-Tooth Disease with Pyramidal Involvement

Axonal Charcot-Marie-Tooth disease with pyramidal involvement is a rare inherited nerve disease. In this condition, the long nerves to the feet and hands (peripheral nerves) slowly become damaged on the axon side, and the nerve tracts in the brain and spinal cord that control movement (pyramidal pathways) are also affected. This mixed damage can cause weak, thin muscles in the feet and hands, foot deformity, balance problems, and also spastic, stiff legs with brisk reflexes. There is no cure yet, so treatment focuses on symptoms, keeping mobility, protecting joints, and supporting the person and family for the long term. ScienceDirect+4MalaCards+4Wiley Online Library+4

Axonal Charcot-Marie-Tooth disease with pyramidal involvement is a rare, inherited nerve disease. It mainly damages the long “wire-like” part of the peripheral nerves (the axon), which carry signals between the spinal cord and the muscles and skin. Because the axons slowly break down, people develop weakness and wasting of muscles in the feet, legs, hands, and sometimes arms, together with numbness or reduced feeling. This “axonal” pattern is often called Charcot-Marie-Tooth type 2 (CMT2).PubMed+1

Axonal Charcot-Marie-Tooth disease with pyramidal involvement is a rare inherited nerve disease. In this condition, the long nerves to the feet and hands (peripheral nerves) slowly become damaged on the axon side, and the nerve tracts in the brain and spinal cord that control movement (pyramidal pathways) are also affected. This mixed damage can cause weak, thin muscles in the feet and hands, foot deformity, balance problems, and also spastic, stiff legs with brisk reflexes. There is no cure yet, so treatment focuses on symptoms, keeping mobility, protecting joints, and supporting the person and family for the long term. ScienceDirect+4MalaCards+4Wiley Online Library+4

In this special form, there is also pyramidal involvement. “Pyramidal” means that the long motor pathways inside the brain and spinal cord (the corticospinal tracts) are affected. These tracts control fine voluntary movement. When they are involved, people may show “upper-motor-neuron” or pyramidal signs such as increased muscle tone (spasticity), brisk reflexes, and an up-going big toe when the doctor strokes the sole of the foot (extensor plantar response).PubMed+1

So, axonal CMT with pyramidal involvement is a mixed problem: the peripheral nerves are damaged like in typical CMT, and at the same time, the central motor pathways show mild damage. People usually have the classic features of CMT (foot deformities, walking difficulty, distal weakness and numbness) and in addition show pyramidal signs, but often without very severe stiffness or spastic walking.PubMed+1

This condition is genetic. It is caused by changes (mutations) in certain genes that are important for nerve structure and function. Several genes have been linked to axonal CMT with pyramidal signs, including MORC2, MFN2, GDAP1, HSPB1, EGR2, and others. These genes help maintain the health of axons, mitochondria, and myelin support systems. When they are abnormal, both the peripheral nerves and sometimes central pathways can be affected.Wiley Online Library+1

Other names

Doctors and researchers may use several other names or phrases for this condition. All point to a similar clinical picture of axonal CMT plus pyramidal signs:

1. Charcot-Marie-Tooth disease (CMT) – the main umbrella term for inherited motor–sensory neuropathies that cause slowly progressive weakness and sensory loss in the limbs.nhs.uk+1

2. Hereditary motor and sensory neuropathy (HMSN) – an older name for CMT; sometimes subtypes with pyramidal features are called HMSN with pyramidal signs, or HMSN type V.Neuromuscular+1

3. Axonal Charcot-Marie-Tooth disease (CMT2) – used when nerve conduction studies show an axonal pattern (low amplitudes with relatively preserved velocities). The pyramidal involvement is then mentioned as an extra feature, such as “CMT2 with pyramidal signs.”PubMed+1

4. CMT with pyramidal features / CMT with pyramidal signs – terms used in research papers describing families in which typical CMT signs coexist with brisk reflexes, increased tone, and extensor plantar responses.PubMed+1

5. Autosomal dominant CMT2Z (MORC2-related) – a named subtype where MORC2 gene mutations cause an axonal neuropathy with additional pyramidal signs such as increased tone and extensor plantar responses.MalaCards+1

6. MFN2-related axonal CMT with central involvement – MFN2 mutations usually cause CMT2A, but in some families, central signs (including pyramidal features) have been reported, so the term “MFN2 variant syndrome with pyramidal signs” may be used.Frontiers+1

7. EGR2-related CMT with pyramidal signs – EGR2 gene variants can produce a complex picture combining peripheral neuropathy and central (pyramidal) features.PMC+1

Types

There is no single official “type list” just for axonal CMT with pyramidal signs, but researchers often classify it by the underlying gene and by age of onset. Some useful clinical “types” in simple language are:

1. Adult-onset axonal CMT with mild pyramidal signs
In some families, symptoms start in teenage years or adulthood with typical distal weakness, pes cavus, and sensory loss. Pyramidal signs are mild: reflexes may be brisk, and the plantar responses can be extensor, but walking is not very spastic. This pattern was described in early reports of CMT with pyramidal features.PubMed+1

2. Early-onset axonal CMT with marked pyramidal signs
In other families, symptoms begin in infancy or early childhood. Children may have delayed motor milestones, hypotonia (floppiness), and then develop both neuropathy features and clear pyramidal signs such as stiffness and scissoring of the legs. This has been reported with MORC2 and other genes.Frontiers+1

3. MORC2-related axonal CMT2Z with pyramidal signs
This genetic subtype (CMT2Z) is due to MORC2 variants. People show axonal neuropathy with distal weakness, cramps, sensory loss, and additional pyramidal signs. Some individuals also have learning difficulties or mild intellectual problems.MalaCards+1

4. MFN2-related axonal CMT with central features
MFN2 mutations are a common cause of axonal CMT2A. In some families, there are extra features such as optic atrophy, cerebellar signs, or pyramidal signs, so this can be thought of as a “mixed peripheral and central” type of axonal CMT.Frontiers+1

5. GDAP1-related axonal CMT with pyramidal features
GDAP1 mutations can cause autosomal recessive axonal CMT. Some reported families show a phenotype with pyramidal signs (brisk reflexes and extensor plantar responses) in addition to the neuropathy.Frontiers+1

6. HSPB1-related axonal CMT / distal HMN with pyramidal signs
Mutations in HSPB1 usually cause distal hereditary motor neuropathy or CMT2F. Case series show that some individuals develop brisk reflexes and other central signs, making this another “axonal CMT with pyramidal involvement” type.PFM Journal+1

7. EGR2-related CMT with complex phenotype
EGR2 variants can lead to a combination of demyelinating or axonal neuropathy plus central nervous system features, including pyramidal signs. This is sometimes grouped as a complex CMT phenotype rather than a pure peripheral neuropathy.PMC+1

8. Infantile-onset complex CMT with pyramidal and extra features
Some reports describe infants with severe hypotonia, delayed milestones, intellectual disability, dystonic postures, pyramidal signs, and neuroimaging changes. These are complex CMT phenotypes involving both peripheral and central structures.Frontiers+1

9. CMT plus hereditary spastic paraplegia overlap
Because pyramidal signs are also the main feature of hereditary spastic paraplegia (HSP), some patients show overlapping CMT and HSP, likely due to shared or interacting genes. Clinically, this looks like axonal peripheral neuropathy plus progressive spastic paraparesis.Neuromuscular+1

10. Axonal CMT2 with occasional pyramidal signs
Large reviews of axonal CMT note that pyramidal signs are rare but reported in multiple subtypes. In such cases, physicians may still label the disease by the main CMT type and gene but mention “with pyramidal signs” in the description.PubMed+1

Causes

Remember, the core cause is a genetic change. The items below list specific gene-related causes and contributing factors.

1. MORC2 gene mutations (CMT2Z)
Changes in the MORC2 gene are a well-recognized cause of autosomal-dominant axonal CMT with pyramidal signs. MORC2 is involved in chromatin remodeling and neuronal survival. Pathogenic variants disrupt normal nerve function, causing axonal degeneration in peripheral nerves and sometimes damage to central motor pathways, leading to pyramidal signs.Wiley Online Library+1

2. MFN2 gene mutations (CMT2A)
MFN2 controls mitochondrial fusion and movement along axons. Mutations cause axonal neuropathy by disturbing energy supply and axonal transport. Some MFN2-related cases have central involvement, which can result in pyramidal signs together with optic atrophy or cerebellar signs.Frontiers+1

3. GDAP1 gene mutations
GDAP1 is important for mitochondrial fission and oxidative stress responses. Mutations, usually autosomal recessive, cause early-onset axonal neuropathy. In certain families, pyramidal signs have been described, suggesting combined peripheral and central tract involvement.Frontiers+1

4. HSPB1 gene mutations (CMT2F / dHMN)
HSPB1 encodes a small heat-shock protein that protects neurons from stress. Pathogenic variants cause axonal degeneration in motor neurons. Some individuals present with neuropathy plus brisk reflexes and increased tone, reflecting pyramidal involvement.PFM Journal+1

5. EGR2 gene mutations
EGR2 is a transcription factor that regulates myelin genes. Certain EGR2 variants cause a complex phenotype with both peripheral neuropathy and central nervous system signs, including pyramidal features, particularly in early-onset or severe cases.PMC+1

6. Other axonal CMT2 gene mutations (e.g., LRSAM1, GNB4, KIF5A)
CMT2 is genetically very diverse, with many genes involved in axonal health, transport, and synaptic function. Some of these genes have been reported in patients who also show pyramidal signs, though the association is less common and usually based on small series or case reports.ScienceDirect+1

7. De novo dominant mutations
In several families, the mutation arises “de novo,” meaning it appears for the first time in the affected child and was not present in the parents. These new dominant changes in CMT-related genes can produce severe phenotypes with both axonal neuropathy and pyramidal involvement.Frontiers+1

8. Autosomal recessive inheritance with consanguinity
When both parents carry a recessive mutation in a CMT-related gene (such as GDAP1), their child may inherit both copies and develop early, severe axonal neuropathy. In some of these recessive forms, pyramidal signs have been observed, particularly in communities with higher consanguinity.Frontiers+1

9. Complex CMT phenotypes involving brain and spinal cord
Some genetic variants do not stay limited to peripheral nerves. They also affect central neurons or their connections, especially corticospinal tracts. This broader effect explains why pyramidal signs develop on top of an axonal CMT phenotype.Frontiers+1

10. Mitochondrial dysfunction in long axons
Many CMT genes (MFN2, GDAP1, others) influence mitochondrial shape and movement. When mitochondria cannot move correctly along long axons, those axons slowly degenerate. If this process also affects corticospinal tract axons, pyramidal signs appear alongside peripheral neuropathy.Frontiers+1

11. Impaired axonal transport
Axons depend on motor proteins to move cargo (organelles, proteins, RNA) up and down the nerve. Several CMT-related genes are part of this transport system. Their disruption leads to length-dependent axonal degeneration, especially in the longest nerves of the legs, and may also damage long central tracts, causing pyramidal involvement.ScienceDirect+1

12. Abnormal myelin–axon support in some CMT types
Even though axonal CMT is defined by axon damage, myelin-forming cells still support axons. Mutations in certain myelin-related genes (e.g., EGR2) can indirectly injure axons and also influence central white matter, giving a combined peripheral and pyramidal picture.PMC+1

13. Shared pathways with hereditary spastic paraplegia genes
Some patients show overlap between CMT and hereditary spastic paraplegia (HSP). Shared cellular pathways, such as axonal transport or lipid metabolism, may explain why a mutation primarily recognized in one disease group causes pyramidal signs in a CMT phenotype.Neuromuscular+1

14. Central nervous system susceptibility in certain variants
In a few genes, the same mutation can cause either pure CMT or complex CMT with central involvement. This suggests that additional factors—such as genetic background or environmental stress—may push the disease to involve pyramidal tracts in some individuals.Frontiers+1

15. Early-onset developmental impact on brain connectivity
When the mutation acts during early brain development, motor pathways may never form normally. This can lead to delayed milestones and strong pyramidal signs along with axonal neuropathy, as reported in infantile complex CMT phenotypes.Frontiers+1

16. Modifying effect of other genetic variants
People carry many genetic variants. Some additional variants may worsen axonal vulnerability or central tract health. For example, case reports describe families with simultaneous MFN2 and GDAP1 variants, suggesting gene–gene interactions that may modify the clinical picture.Frontiers+1

17. Age-related axonal degeneration on top of CMT
As people with CMT age, natural wear-and-tear processes may speed up axonal loss in both peripheral and central pathways, making pyramidal signs more visible later in life even if they were subtle in youth.PubMed+1

18. Metabolic or vascular stress in genetically vulnerable nerves
Conditions such as diabetes, thyroid disease, or vascular risk factors can worsen neuropathy in people who already have a CMT gene mutation. Although they do not cause CMT, they can aggravate axonal injury and sometimes make central signs more obvious.Patient+1

19. Nutritional deficiencies as contributors
Deficiencies of vitamin B12 or other nutrients can add extra damage to nerves. In a person with underlying axonal CMT, this may increase weakness and balance problems and possibly unmask subtle pyramidal signs, although the main cause remains the genetic mutation.Patient+1

20. Unknown or yet-undiscovered CMT gene mutations
Despite modern testing, some families with axonal CMT and pyramidal signs still have no identified mutation. It is likely that new CMT genes or regulatory regions will be discovered in the future, explaining these unsolved cases.ScienceDirect+1

Symptoms

1. Distal leg weakness and foot drop
Weakness usually starts in the muscles that lift the foot and toes. People may catch their toes on the ground, trip often, or notice they cannot run as before. This “foot drop” is a typical CMT symptom and often the first sign.Mayo Clinic+1

2. Muscle wasting in feet and calves
Over time, the small muscles of the feet and then the calves shrink. The legs may look thin below the knees, and doctors sometimes describe a “stork-leg” or “inverted champagne bottle” appearance in classic CMT.PFM Journal+1

3. Foot deformities (pes cavus and hammertoes)
Because some muscles weaken more than others, the foot arch becomes very high (pes cavus) and the toes can curl (hammertoes). These deformities make shoe fitting hard and can cause calluses and pain when walking.PFM Journal+1

4. Distal hand weakness and fine motor difficulties
Later, the muscles of the hands may weaken. People can struggle with buttons, zippers, handwriting, or tasks that need fine finger control. Grip strength can fall, and small hand muscles may waste.PFM Journal+1

5. Numbness and decreased sensation in feet and hands
Loss of feeling for vibration, position, light touch, and pain is common, especially in the feet. This can make it hard to feel the ground, increasing the risk of falls and unnoticed skin injuries. Hands may later become numb as well.Mayo Clinic+1

6. Balance problems and unsteady walking
Weakness plus sensory loss leads to poor balance, especially in the dark or on uneven surfaces. People may widen their stance, sway, or need to look at their feet while walking to stay steady.nhs.uk+1

7. Brisk reflexes and extensor plantar responses (pyramidal signs)
Unlike many typical CMT patients who have absent ankle reflexes, people with pyramidal involvement can have brisk or even exaggerated knee reflexes and an up-going big toe when the sole is stroked. These signs show involvement of the corticospinal tracts.PubMed+1

8. Increased muscle tone or mild spasticity
Some individuals notice their legs feel stiff, especially when walking quickly or when they are tired. On examination, the doctor may detect increased resistance when passively moving the limbs, which is called spasticity and reflects pyramidal involvement.Practical Neurology+1

9. Gait abnormalities (steppage or spastic-steppage gait)
The combination of foot drop from peripheral weakness and stiffness from pyramidal signs can create a mixed gait pattern. People may lift their legs higher than normal (steppage gait) and at the same time show some reduced knee flexion or scissoring features from increased tone.Patient+1

10. Muscle cramps and fatigue
Many people experience painful cramps in the calves or feet, especially at night or after activity. General fatigue is also common, because walking and daily tasks require extra effort when nerves and muscles are weak.PFM Journal+1

11. Neuropathic pain or discomfort
Some individuals have burning, tingling, electric-shock-like pain, or deep aching in their feet and legs. This neuropathic pain comes from damaged sensory nerves sending abnormal signals to the brain.Mayo Clinic+1

12. Hand clumsiness and difficulty with coordination
When both peripheral weakness and pyramidal involvement affect the upper limbs, tasks that need coordination—like writing neatly or playing an instrument—can become noticeably harder. Fine hand control may gradually decline.PFM Journal+1

13. Frequent tripping and falls
Because of foot drop, balance problems, and stiffness, people may fall more often, especially on stairs or uneven ground. Falls can lead to injuries and fear of walking, which further reduces activity and muscle strength.Patient+1

14. Possible learning difficulties or mild cognitive problems in some genetic types
In certain subtypes, such as MORC2-related CMT2Z, some patients have learning difficulties or mild cognitive issues in addition to neuropathy and pyramidal signs. This shows that the underlying gene change can also affect brain networks beyond motor tracts.MalaCards+1

15. Emotional impact and reduced quality of life
Living with a progressive nerve condition can cause worry, sadness, or anxiety, especially about future mobility and independence. Physical symptoms like pain, fatigue, and walking difficulty can limit work, school, and social activities, affecting mental well-being.CMT Research Foundation+1

Diagnostic tests

Physical exam

1. General neurological examination
The neurologist checks muscle strength, tone, reflexes, and coordination across all four limbs. In axonal CMT with pyramidal involvement, they often find distal weakness and wasting, reduced or absent ankle reflexes but brisk knee reflexes, and extensor plantar responses. This pattern shows both peripheral neuropathy and pyramidal tract signs.PFM Journal+1

2. Gait and posture assessment
The doctor watches how the person stands and walks, including heel-walking, toe-walking, and tandem (heel-to-toe) walking. A high-stepping gait from foot drop, together with some stiffness or scissoring from pyramidal involvement, helps distinguish this complex pattern from pure CMT or pure spastic paraplegia.Patient+1

3. Examination of foot and hand shape
The clinician inspects the feet for high arches, hammertoes, calluses, and ankle instability, and the hands for wasting of small muscles. These deformities support the diagnosis of long-standing neuropathy, guiding further tests toward CMT rather than other causes of pyramidal signs.nhs.uk+1

4. Sensory examination
Using simple tools like cotton, a pin, tuning fork, or proprioception testing, the neurologist maps out areas of reduced sensation. In CMT, there is often a “length-dependent” pattern: sensation is poorest in the feet, better in the legs, and often normal near the trunk and face. This helps confirm peripheral nerve involvement alongside the central signs.Mayo Clinic+1

5. Cranial nerve and eye examination
Because some axonal CMT subtypes can involve the optic nerves, eye movements, or other brainstem functions, doctors check vision, eye movements, facial strength, speech, and swallowing. Any abnormalities here, combined with pyramidal and peripheral signs, suggest a complex CMT phenotype rather than a purely peripheral neuropathy.Practical Neurology+1

---

Manual tests

1. Manual muscle testing (MRC grading)
The doctor tests each muscle group against resistance and grades strength (for example, from 0 to 5 on the Medical Research Council scale). Manual testing shows which muscles are weak, usually distal muscles first, and helps track progression over time.PFM Journal+1

2. Romberg test
The person stands with feet together and then closes their eyes. If they sway or fall mainly when their eyes are closed, it suggests sensory loss in the feet. In axonal CMT, a positive Romberg test indicates impaired position sense due to peripheral neuropathy.nhs.uk+1

3. Heel-to-toe and single-leg stance tests
The clinician may ask the person to walk heel-to-toe in a straight line or stand on one leg. Difficulty with these tasks reflects a combination of weakness, sensory loss, and possibly pyramidal involvement, helping to grade balance problems in a simple way.Patient+1

4. Spasticity assessment by passive movement
To look for pyramidal involvement, the doctor slowly and then quickly moves the person’s joints, such as the knee or ankle, and feels for increased resistance or a “catch.” This bedside test estimates spasticity and complements reflex findings when diagnosing pyramidal signs.Practical Neurology+1

5. Functional tests such as timed up-and-go or chair rise
Simple timed tasks—standing up from a chair, walking a short distance, turning, and sitting down—help measure overall mobility. In axonal CMT with pyramidal signs, these tests show how distal weakness, stiffness, and imbalance combine to affect daily function.Patient+1

---

Lab and pathological tests

1. Basic blood tests to rule out other neuropathies
Blood tests for blood sugar, vitamin B12, thyroid function, kidney and liver function, and inflammatory markers are done to exclude other causes of neuropathy, such as diabetes, vitamin deficiency, or autoimmune disease. Normal results support a hereditary neuropathy like CMT rather than an acquired cause.ARUP Consult+1

2. Genetic testing panels for CMT and related neuropathies
Modern CMT diagnosis relies heavily on genetic testing. Panels can look at many CMT-related genes (MFN2, MORC2, GDAP1, HSPB1, EGR2, GJB1, and others) at once. Finding a pathogenic mutation that matches the clinical picture confirms the diagnosis and helps classify the specific subtype with or without pyramidal features.ARUP Consult+1

3. Nerve biopsy (used less often now)
In uncertain cases, a small sensory nerve (usually from the leg) may be removed and examined under a microscope. In axonal CMT, the biopsy shows loss of axons out of proportion to demyelination. However, because genetic tests are now widely available and safer, nerve biopsy is reserved for rare situations.PubMed+1

4. Cerebrospinal fluid (CSF) analysis in selected cases
If the doctor is worried about inflammatory or immune-mediated neuropathies that can mimic CMT, a lumbar puncture may be performed. In hereditary axonal CMT, CSF protein and cells are usually normal, which helps rule out acquired demyelinating neuropathy or infection.ARUP Consult+1

---

Electrodiagnostic tests

1. Nerve conduction studies (NCS)
NCS measure how fast and how strongly electrical signals travel through peripheral nerves. In axonal CMT, amplitudes of sensory and motor responses are reduced (showing axon loss), while conduction velocities are often near normal or only mildly slowed. This pattern distinguishes axonal CMT from demyelinating CMT types.PubMed+1

2. Electromyography (EMG)
EMG involves inserting a thin needle into muscles to record electrical activity. In axonal CMT, EMG shows signs of chronic denervation and reinnervation, such as large motor units and reduced recruitment. It helps confirm a neuropathic, length-dependent process and rule out primary muscle diseases.PubMed+1

3. Motor evoked potentials and central conduction studies
To detect pyramidal involvement, doctors may use transcranial magnetic stimulation to measure motor evoked potentials (MEPs). Delayed or abnormal central conduction times suggest corticospinal tract dysfunction, supporting the diagnosis of “axonal CMT with pyramidal signs” rather than pure peripheral neuropathy.Practical Neurology+1

---

Imaging tests

1. MRI of brain and spinal cord
MRI can be done to look for other causes of pyramidal signs, such as multiple sclerosis, spinal cord compression, or stroke. In some complex CMT cases, MRI may show subtle changes in white matter or spinal cord tracts, but often it is normal. A normal MRI with clear pyramidal signs supports a genetic diagnosis like CMT with pyramidal features.Frontiers+1

2. MRI neurography or nerve ultrasound
Advanced imaging of peripheral nerves can show thinning or mild enlargement of nerves and changes in surrounding tissues. While not specific, these methods can support the diagnosis of hereditary neuropathy and help distinguish it from nerve entrapment or inflammatory conditions.Radiopaedia+1

3. Orthopedic X-rays of feet, ankles, and spine
Plain X-rays help assess the severity of foot deformities (pes cavus, hammertoes), ankle instability, and possible spinal curvature. They are important for planning braces, physiotherapy, or surgery to improve walking and prevent joint problems in people with CMT and pyramidal involvement.nhs.uk+1

Non-pharmacological treatments

1. Individual physiotherapy program
   A physiotherapist builds a safe exercise plan to keep muscles as strong and flexible as possible, slow contractures, and maintain walking. Purpose is to improve strength, balance, and endurance. Mechanism is simple: repeated, well-planned movement helps the nervous system use remaining nerve fibers better and keeps joints from becoming stiff. PMC+2Physiopedia+2

2. Occupational therapy for daily tasks
   Occupational therapists teach easier ways to dress, wash, cook, and use a computer when hand and leg weakness is present. Purpose is to keep independence at home, school, and work. Mechanism is to adapt tasks, use special tools, and change posture so weak muscles are protected while still being used. PMC

3. Gait and balance training
   Special walking drills, treadmill work with support, balance boards, and dual-task exercises help reduce falls. Purpose is safer, more stable walking and better confidence. Mechanism: the brain learns to use visual cues, trunk muscles, and assistive devices to compensate for weak ankle and foot muscles. PMC+1

4. Targeted strengthening exercises
   Low-load, high-repetition training focuses on muscles that still have working nerves, especially around hips, core, and shoulders. Purpose is to support weak distal muscles and protect joints. Mechanism: strengthening preserved motor units improves overall function without over-fatiguing fragile distal nerves. ScienceDirect

5. Stretching and spasticity management
   Slow, regular stretching of calf, hamstring, and hip muscles helps control pyramidal-related stiffness. Purpose is to reduce spasms, delay contractures, and improve walking pattern. Mechanism: gentle stretching and positioning reduce muscle over-activity and maintain muscle length, making medicines for spasticity work better when used. Charcot-Marie-Tooth Association+1

6. Orthoses: ankle-foot orthoses (AFOs)
   Light plastic or carbon AFOs hold the ankle in a safer position and prevent foot drop. Purpose is to clear the foot during swing and reduce tripping. Mechanism: the brace replaces the weak dorsiflexor muscles and stabilizes the ankle, which improves walking speed and reduces energy cost. PMC+1

7. Custom therapeutic footwear
   Shoes with extra depth, high heel counters, and shock-absorbing insoles protect the high-arched or unstable CMT foot. Purpose is to spread pressure, prevent skin breakdown, and improve comfort. Mechanism: correct shoe design redistributes plantar pressure and supports joints that are unstable due to muscle imbalance. PMC+1

8. Walking aids (cane, crutch, walker)
   A stick, crutch, or wheeled walker may be used when balance and leg strength decline. Purpose is fall prevention and energy saving during longer walks. Mechanism: the aid widens the base of support and allows arm muscles to share the load with weak legs. nhs.uk+1

9. Hand and fine-motor therapy
   Hand therapists use putty, grip tools, and task-based practice to maintain pinch, grip, and finger control. Purpose is to keep writing, smartphone use, and self-care as easy as possible. Mechanism: repeated fine-motor practice and splints reduce deformity and support remaining motor units. PMC

10. Home and school adaptations
    Simple changes such as grab bars, non-slip mats, shower chairs, and ramps lower risk of injury. Purpose is safe movement in daily environments. Mechanism: reducing environmental hazards compensates for muscle weakness, sensory loss, and spasticity, so fewer falls and fractures occur. nhs.uk+1

11. Fatigue management and energy conservation
    Therapists teach pacing, use of rests, and task planning. Purpose is to reduce exhaustion from the high effort of walking with weak and spastic muscles. Mechanism: spreading heavy tasks across the day and using aids lowers continuous muscle demand, which protects nerves from overuse. Muscular Dystrophy Association+1

12. Cognitive-behavioural therapy for chronic pain
    Psychologists use CBT to help people cope with long-term neuropathic pain and disability. Purpose is to reduce distress, anxiety, and pain-related fear. Mechanism: CBT changes thought patterns and behaviours that increase pain perception, helping the brain process pain signals in a calmer way. PubMed+1

13. Respiratory and postural training
    In advanced cases with trunk weakness or scoliosis, breathing exercises and posture work may be needed. Purpose is to maintain lung function and reduce chest infections. Mechanism: upright sitting, deep breathing drills, and supported coughing help lungs expand and clear mucus despite weak muscles. Muscular Dystrophy Association+1

14. Spasticity self-management (positioning and splinting)
    Night splints, proper seating, and regular change of position help control pyramidal muscle over-activity. Purpose is to keep joints in neutral and reduce painful spasms. Mechanism: positioning reduces reflex triggers in muscles and tendons, making them less likely to tighten suddenly. FDA Access Data+1

15. Vocational and educational rehabilitation
    Specialists advise on school accommodations, job choice, and workplace changes. Purpose is to keep the person engaged in study or work despite disability. Mechanism: choosing tasks with less heavy physical demand and providing tools like ergonomic chairs or speech-to-text software reduces strain on weak limbs. Muscular Dystrophy Association

16. Genetic counselling for family planning
    Genetic counsellors explain inheritance patterns, testing options, and risks to future children. Purpose is informed decisions about pregnancy and testing. Mechanism: clear information on the disease gene and its transmission helps families plan early screening and supportive care. MalaCards+1

17. Patient and caregiver education programs
    Teaching about foot care, falls, nutrition, and drug side effects makes care safer. Purpose is to turn complex medical advice into simple daily routines. Mechanism: when families understand the disease, they spot problems early and seek help before serious complications appear. nhs.uk+1

18. Peer support groups and online communities
    Meeting others with Charcot-Marie-Tooth disease reduces isolation and fear. Purpose is emotional support and practical advice. Mechanism: shared experience improves mood and adherence to therapy, and helps people learn from others’ coping strategies. CMT Research Foundation

19. Regular multidisciplinary review
    Follow-up with a neurologist, physiatrist, physiotherapist, orthopaedic surgeon, and geneticist is vital. Purpose is to adjust treatment as the disease slowly changes. Mechanism: team care allows early handling of new spasticity, foot deformity, scoliosis, or swallowing and breathing problems. Muscular Dystrophy Association+1

20. Assistive technology and smart devices
    Voice-to-text software, adapted keyboards, and smart home tools can greatly help. Purpose is to keep independence with minimal physical strain. Mechanism: technology replaces small, difficult hand movements and reduces the number of steps needed for common tasks. Muscular Dystrophy Association

Drug treatments

There are no FDA-approved drugs that cure axonal Charcot-Marie-Tooth disease with pyramidal involvement. Most medicines listed here are approved for conditions like neuropathic pain or spasticity and may be used off-label in this disease by specialists. Always ask a neurologist, especially for a child or teenager. Muscular Dystrophy Association+1

Dietary molecular supplements

Supplements should never replace a balanced diet or prescribed medicines. Many have limited evidence in CMT and are mainly extrapolated from other neuropathies. Always discuss with a doctor, especially for teenagers. Health+1

1. Alpha-lipoic acid (ALA)
   ALA is an antioxidant that can reduce oxidative stress in nerves and may improve pain and nerve conduction in diabetic neuropathy. Functional role is to protect nerve cells from free-radical damage and improve blood flow. Common studied adult dose is about 600 mg/day. Mechanism: improves micro-circulation, reduces inflammation, and supports mitochondrial function. Dove Medical Press+3PMC+3MDPI+3

2. Acetyl-L-carnitine (ALC)
   ALC helps mitochondria make energy and may support regrowth of damaged axons. Functional role is to reduce neuropathic pain and support nerve repair. Adult doses in studies are usually 1–3 g/day in divided doses. Mechanism: improves mitochondrial metabolism and may increase nerve growth factor signaling. ScienceDirect+4PMC+4PLOS+4

3. B-complex vitamins (B1, B6, B9, B12)
   These vitamins are vital for nerve health and myelin. Functional role is to support nerve conduction and prevent deficiency-related neuropathy. Doses vary; high doses should be supervised, especially B6, which can itself cause neuropathy if taken in excess. Mechanism: support energy production, neurotransmitter synthesis, and myelin maintenance. The Times of India+3Cleveland Clinic+3PubMed+3

4. Vitamin D
   Vitamin D helps bone and muscle health and may influence nerve inflammation and pain perception. Functional role is to maintain bone density in people with reduced activity and reduce fall risk. Typical goal is to reach normal serum vitamin D levels using diet, sun, or supplements. Mechanism: modulates immune and inflammatory pathways. Health

5. Omega-3 fatty acids (fish oil, EPA/DHA)
   Omega-3 fats are structural parts of nerve cell membranes. Functional role is to support nerve repair and may reduce neuropathic pain in experimental studies. Doses in adults vary (often 1–3 g/day EPA+DHA). Mechanism: anti-inflammatory effects and support of myelin and axon regeneration. Cochrane+5PMC+5Frontiers+5

6. N-acetyl cysteine (NAC)
   NAC is a precursor of glutathione, a key antioxidant. Functional role is potential reduction of oxidative stress and support of other pain treatments. Doses vary; high doses must be monitored for stomach upset and rare allergic reactions. Mechanism: boosts intracellular glutathione and may dampen neuroinflammation. Health

7. Coenzyme Q10
   CoQ10 supports mitochondrial energy production. Functional role is to help cells with high energy demand, including nerve and muscle cells. Doses often range from 100–300 mg/day in adults. Mechanism: part of the electron transport chain, reducing oxidative stress and improving cellular energy. ScienceDirect

8. Magnesium
   Magnesium is important for nerve and muscle function. Functional role is to reduce cramps, improve sleep, and support overall neuromuscular health. Doses vary; too much can cause diarrhea, and kidney disease needs caution. Mechanism: modulates NMDA receptors and muscle excitability. Verywell Health+1

9. Curcumin (from turmeric)
   Curcumin has anti-inflammatory and antioxidant properties. Functional role is experimental relief of pain and stiffness. Doses and absorption vary widely; formulations with piperine or lipids are better absorbed. Mechanism: downregulates inflammatory cytokines and oxidative damage. Cureus+1

10. Glutamine (in selected cases)
    Glutamine is a conditionally essential amino acid. It has mainly been studied in chemotherapy-induced neuropathy. Functional role is experimental support of nerve repair in selected situations. Mechanism: may support nerve metabolism and gut health, but evidence in inherited neuropathy is limited. Health

Immune-modulating, regenerative and stem-cell-related approaches

These are research or highly specialized treatments, not standard care. They should only be used in clinical trials or specialist centers.

1. Gene therapy targeting the CMT gene
   Gene therapy aims to correct the faulty gene that causes axonal CMT with pyramidal involvement. Functional role is to fix the root cause, not just symptoms. Mechanism: viral or plasmid vectors deliver a healthy gene or silence the harmful one, so nerve cells can make normal proteins. Early trials in several CMT subtypes are ongoing. AFM Téléthon+3CMT Research Foundation+3Institut Myologie+3

2. Neurotrophin-3 (NT-3) gene therapy
   NT-3 is a growth factor that supports Schwann cells and axon regeneration. Functional role is to improve nerve conduction and muscle strength. Mechanism: AAV vectors deliver the NT-3 gene so muscles or nerves produce more NT-3 for a long time, promoting remyelination and axon repair. Trials in CMT1A and CMT2 models show promising results. Charcot-Marie-Tooth News+5PMC+5Nature+5

3. Plasmid-based gene medicines for CMT
   Some early clinical trials use plasmid DNA to deliver helpful genes without viral vectors. Functional role is repeated dosing with lower immune reaction. Mechanism: injected plasmids enter cells and drive production of proteins that may protect or repair nerves. Evidence is still early, and safety and long-term benefit are under study. HNF Cure+2CMT Research Foundation+2

4. Mesenchymal stem cell therapy (experimental)
   Stem cells from bone marrow or umbilical cord are being studied for neuropathy. Functional role is to create a more healing environment around damaged nerves. Mechanism: cells release growth factors and anti-inflammatory molecules and may differentiate into support cells, improving nerve conduction in some models. This remains experimental and not routine care. ClinicalTrials+5PMC+5DVC Stem+5

5. PXT3003 combination (baclofen + naltrexone + sorbitol)
   PXT3003 is a fixed-dose oral combination studied mainly in CMT1A. Functional role is to modulate pathways involved in myelin over-expression and nerve dysfunction. Mechanism: uses low doses of three drugs to rebalance signaling in Schwann cells. Phase 3 results have been mixed, and it is not yet approved. NIHR Innovation Observatory+6ClinicalTrials+6PMC+6

6. Immune-modulating biologics (very selected cases)
   In rare overlap situations with immune neuropathies, biologics or intravenous immunoglobulin (IVIG) may be considered. Functional role is to calm harmful immune attack. Mechanism: antibodies in IVIG or targeted biologics modify immune cell activity. This is not standard for pure genetic axonal CMT but may appear in complex cases in research reports. Muscular Dystrophy Association+1

Surgical treatments

1. Soft-tissue procedures (plantar fascia release, tendon lengthening)
   In high-arched, tight feet, surgeons may cut or lengthen tight fascia and tendons. Purpose is to reduce deforming forces and allow the foot to sit flatter. Mechanism: releasing tight tissues lets bones move into a more neutral position and reduces pain under the foot. PubMed+2ENMC+2

2. Tendon transfer for foot drop
   Weak ankle dorsiflexors cause the toes to drag. Surgeons can move a stronger tendon (such as tibialis posterior or extensor hallucis longus) to the top of the foot. Purpose is to lift the foot during walking without relying only on a brace. Mechanism: rerouting muscle power to restore dorsiflexion and improve gait. PubMed+2www.elsevier.com+2

3. Osteotomies (bone-cutting to correct cavus deformity)
   When the foot bones are fixed in a high arch or twisted position, surgeons cut and realign them (e.g., calcaneal or first-metatarsal osteotomy). Purpose is a plantigrade, more stable foot. Mechanism: bone reshaping changes weight-bearing lines and reduces pressure and ankle instability. Bioscientifica+3PMC+3PMC+3

4. Arthrodesis (joint fusion) in severe deformity
   If joints are very damaged or unstable, fusing them in a good position may be needed. Purpose is to stabilize the foot and ankle to reduce pain and falls. Mechanism: bones are fixed together so they no longer move abnormally, trading flexibility for stability. ENMC+2Charcot-Marie-Tooth Association+2

5. Spine and contracture surgery
   In selected patients with severe scoliosis or fixed joint contractures, spinal or limb surgery may be offered. Purpose is to prevent lung compromise, reduce pain, and make care easier. Mechanism: correcting curves and releasing tight tissues improves posture and reduces secondary complications. Wiley Online Library+1

Preventions

1. Avoid nerve-toxic drugs
   Some chemotherapy agents (like vincristine) and high-dose B6 can worsen neuropathy. Doctors should review all medicines before prescribing. nhs.uk+1

2. Protect feet every day
   Check skin, nails, and between toes for cuts or blisters, and wear cushioned shoes and socks. Early treatment of small problems prevents ulcers and infections. Wikipedia+1

3. Keep a healthy body weight
   Extra weight increases stress on weak feet, ankles, and knees and raises fall risk. A balanced diet and regular, safe exercise help reduce load on joints. nhs.uk+1

4. Do regular physiotherapy and home exercises
   Stopping movement leads to faster stiffness and weakness. Continuing tailored exercises delays contractures and helps maintain function for longer. PMC+1

5. Prevent falls at home and outside
   Use rails, good lighting, non-slip shoes, and walking aids when advised. Removing loose rugs and cables lowers fracture risk. nhs.uk+1

6. Manage other health problems (diabetes, thyroid, B12)
   Illnesses like diabetes or vitamin B12 deficiency can add extra nerve damage. Good control of these problems helps protect remaining nerve function. Cleveland Clinic+2PubMed+2

7. Avoid smoking and limit alcohol
   Smoking and heavy alcohol intake harm blood vessels and nerves. Stopping smoking and moderating alcohol help nerve nutrition and overall health. Wikipedia+1

8. Stay up-to-date with vaccines
   Vaccinations against flu, pneumonia, and COVID-19 (as advised) reduce infections that can cause hospital stays and deconditioning in people with mobility problems. nhs.uk

9. Use braces and orthoses as prescribed
   Skipping AFOs or splints increases risk of falls and deformity. Using them consistently supports safer gait and delays need for surgery. Charcot-Marie-Tooth Association+1

10. Attend regular specialist follow-up
    Seeing your neuromuscular team on schedule allows early detection of worsening spasticity, foot deformity, scoliosis, or breathing changes. Early action is always easier than late rescue. Muscular Dystrophy Association+1

When to see a doctor

You should see a neurologist or neuromuscular clinic urgently if there is a sudden or clear change in walking, new frequent falls, or fast-worsening weakness. New severe stiffness or spasms, loss of bladder or bowel control, or problems swallowing or breathing also need immediate review. Persistent burning or electric pain that disturbs sleep, unexplained weight loss, mood changes, or thoughts of self-harm must be discussed with a health professional straight away. For teenagers and children, any change in school performance, fatigue, or behaviour with this disease should trigger a fresh assessment and treatment review.

What to eat and what to avoid

1. Eat: plenty of colourful vegetables and fruits for vitamins and antioxidants. Avoid: very sugary drinks and snacks that add calories but few nutrients. Verywell Health+1

2. Eat: lean proteins like fish, eggs, pulses, and poultry to support muscles. Avoid: frequent large portions of processed meats high in salt and saturated fat.

3. Eat: foods rich in B-vitamins (eggs, dairy, meat, fortified cereals if not vegetarian). Avoid: very restrictive diets without proper planning that can lead to B12 or other deficiencies. Cleveland Clinic+2PubMed+2

4. Eat: sources of omega-3 fatty acids such as oily fish, flaxseed, and walnuts. Avoid: constant fast-food meals rich in trans fats, which may worsen inflammation. Frontiers+2Understanding Animal Research+2

5. Eat: whole grains and legumes for stable energy and gut health. Avoid: heavy, refined-carb meals that cause big blood-sugar swings and fatigue. nhs.uk+1

6. Eat: nuts, seeds, and leafy greens for magnesium and other minerals. Avoid: relying on high-dose mineral supplements without blood tests and medical advice. Verywell Health+1

7. Eat: calcium-rich foods (dairy or fortified alternatives) to keep bones strong when mobility is limited. Avoid: excessive cola and high-salt snacks that may harm bone and kidney health. nhs.uk

8. Eat: enough protein spaced through the day to support muscle repair after physiotherapy. Avoid: skipping many meals, which weakens muscles and worsens fatigue.

9. Eat: plenty of water or low-sugar drinks to stay hydrated. Avoid: energy drinks or very strong caffeine that can disturb sleep and increase muscle twitching.

10. Eat: if you are vegetarian or vegan, plan carefully with a dietitian to cover B12, iron, and omega-3. Avoid: assuming plant-based diets are automatically safe for nerves without checking nutrient levels. Cleveland Clinic+2Verywell Health+2

Frequently asked questions

1. Is axonal Charcot-Marie-Tooth disease with pyramidal involvement curable?
   No. At present there is no cure. Treatment focuses on reducing symptoms, slowing complications, and improving quality of life through physiotherapy, orthoses, medicines for pain and spasticity, and, in some cases, surgery. Research into gene and cell therapies is active but still experimental. AFM Téléthon+3Muscular Dystrophy Association+3ScienceDirect+3

2. Will every person with this disease need a wheelchair?
   Not always. Some people keep walking with braces and aids for many years, while others need a wheelchair for safety or long distances. Early therapy, weight control, and good foot care can delay loss of walking, but the disease course is different for each person. PMC+1

3. Why are there pyramidal signs if this is a peripheral nerve disease?
   In this subtype, the mutation affects both the peripheral nerves and central motor pathways (pyramidal tracts). This is why people can have lower-motor-neuron signs (wasting, weak ankles) and upper-motor-neuron signs (spasticity, brisk reflexes) at the same time. MalaCards+2Wiley Online Library+2

4. Can exercise make the nerves worse?
   Very heavy or high-impact exercise may over-fatigue weak muscles and increase pain, but well-planned, low-to-moderate intensity exercise is usually helpful. It keeps joints flexible, supports heart and lung health, and improves mood. Programs should be designed by a therapist who understands CMT. PMC+2Charcot-Marie-Tooth Association+2

5. Are there special shoes for this disease?
   Yes. High-quality supportive shoes with extra depth, stiff heel counters, and cushioned soles can reduce pain and improve balance. Many people also need custom insoles or braces. A podiatrist or orthotist should guide these choices. PMC+2Wikipedia+2

6. What is the difference between pain from nerves and pain from joints?
   Neuropathic pain often feels burning, electric, or like pins and needles, and may be worse at night. Joint or muscle pain is more aching and linked to movement or position. Many people with this disease have both, so doctors often use more than one approach to control pain. PubMed+1

7. Can diet alone treat this condition?
   No diet can correct the genetic mutation. However, good nutrition supports nerve and muscle health, prevents extra problems like diabetes and obesity, and helps the body respond better to therapy and surgery. Diet is a strong partner, not a replacement, for medical care. Health+1

8. Should I or my child take many supplements “just in case”?
   Taking many high-dose supplements without proven need can be risky and expensive. Some vitamins, such as B6, can damage nerves at high doses. It is safer to test levels, use a balanced diet, and add only targeted supplements under medical supervision. Health+2Cleveland Clinic+2

9. Is surgery always successful in CMT foot deformity?
   Surgery often improves pain and foot position, but it cannot stop the underlying progression of muscle weakness. Outcomes are best when done by surgeons experienced in CMT, with realistic goals and strong rehabilitation afterwards. Bioscientifica+3PubMed+3PMC+3

10. Can teenagers with this disease play sports?
    Many teenagers can enjoy adapted sports and gentle activities like swimming or cycling. Contact sports and activities with a high risk of ankle injury or falls may not be safe. A physiatrist or physiotherapist can help choose suitable sports and protective equipment. PMC+1

11. Will gene therapy be available soon?
    Gene therapy for several CMT types is in early human trials and advanced animal studies. This is encouraging, but it takes years to fully prove safety and effectiveness. Families should watch trusted CMT organizations and clinical trial registries for updates. AFM Téléthon+4CMT Research Foundation+4PMC+4

12. Is this condition the same as multiple sclerosis or cerebral palsy?
    No. Multiple sclerosis and cerebral palsy have different causes and brain findings. Axonal CMT with pyramidal involvement is a hereditary neuropathy that also affects central motor pathways. It usually progresses slowly and has a strong family or genetic pattern. MalaCards+1

13. Can pregnancy worsen this disease?
    Some women with neuromuscular diseases feel more weak or tired during pregnancy, mainly due to extra weight and hormonal changes. Close monitoring by neurology and obstetric teams is important, and medicine plans may need adjustment. FDA Access Data+1

14. How often should follow-up scans or nerve tests be done?
    There is no fixed schedule for everyone. Many specialists repeat nerve conduction studies only when there is a major change in symptoms or for research. Clinical exams, gait assessment, and sometimes spine or foot imaging guide most decisions. Muscular Dystrophy Association+2ScienceDirect+2

15. Where can families find reliable information and support?
    National neuromuscular organizations, CMT-specific foundations, and university hospital websites are good sources. They provide guides, research updates, and contacts for specialists and support groups, helping families navigate this rare and complex disease.
