Hereditary Motor and Sensory Neuropathy Type 5 (HMSN type 5)

Hereditary motor and sensory neuropathy type 5 (HMSN type 5) is a very rare form of Charcot–Marie–Tooth (CMT) disease. Doctors also call it “Charcot–Marie–Tooth disease type 5,” “hereditary motor and sensory neuropathy with pyramidal features,” or “HMSN V.” In this condition, the long nerves to the feet and hands slowly become damaged. This causes weak and thin muscles in the legs and sometimes in the hands. It can lead to foot drop, high-arched feet (pes cavus), walking problems, cramps, and sometimes stiffness and brisk reflexes because of mild spinal cord involvement. The disease usually gets worse slowly over many years. There is no cure yet, so treatment focuses on rehabilitation, pain control, and support. ScienceDirect+4Genetic and Rare Diseases Center+4Orpha.net+4

Hereditary motor and sensory neuropathy type 5 (HMSN type 5, also called Charcot-Marie-Tooth disease type 5 with pyramidal features) is a very rare, inherited nerve disease. It mainly damages:

• the long peripheral nerves that control movement and feeling in the feet and legs

• the pyramidal (corticospinal) tracts in the spinal cord that control muscle tone and reflexes

Because of this double problem, people have both neuropathy (weakness, thin muscles, reduced feeling) and pyramidal signs (stiffness, brisk reflexes, sometimes extensor plantar response). Genetic and Rare Diseases Center+3Orpha.net+3PubMed+3

The disease usually starts in teenage years or adult life. It gets slowly worse over many years. Many people first notice problems with walking, such as tripping, foot drop, or a high-arched foot (pes cavus). Global Genes+2MalaCards+2 HMSN type 5 is usually autosomal dominant. This means one changed gene from one parent is enough to cause the disease. Rare families with recessive patterns are also described. Orpha.net+2PubMed+2

Doctors now know that HMSN type 5 overlaps with hereditary spastic paraplegia (HSP). Some families first labelled as “HMSN V” are later found to have changes in HSP-related genes, such as KIF5A (SPG10) or SPG11. Because of this, some experts suggest not using the label “HMSN V” anymore, but the name is still often used in clinics and rare-disease lists. Thieme Connect+2ScienceDirect+2

Another names

Doctors, researchers, and databases use many other names for the same or very similar condition. You may see: MeSH Browser+4MeSH Browser+4Global Genes+4

• Charcot-Marie-Tooth disease-pyramidal features syndrome – shows that it is a Charcot-Marie-Tooth (CMT) neuropathy with extra pyramidal tract signs (stiffness, brisk reflexes).

• Charcot-Marie-Tooth disease type 5 – CMT type 5 is one of the older CMT subtypes; in this type, spastic or brisk reflexes in the legs are prominent.

• Hereditary motor and sensory neuropathy type 5 (HMSN 5 / HMSN V) – older classification name from the Dyck system for inherited neuropathies.

• Hereditary motor and sensory neuropathy with pyramidal features – highlights the mixture of peripheral neuropathy and corticospinal tract involvement.

• Hereditary sensory-motor neuropathy type V – similar words in a different order, used in some lists and papers.

• Peroneal muscular atrophy with pyramidal tract features – focuses on wasting of the lower-leg muscles (peroneal muscles) plus spastic signs. Springer Link+1

• CMT with pyramidal features or HMSN with pyramidal signs – shorter labels often used in research articles and MeSH / indexing terms. MeSH Browser

All of these names describe one main clinical idea: a hereditary neuropathy with both motor and sensory involvement, plus upper-motor-neuron-type signs in the legs.

Types (clinical patterns)

There is no strict, official “type A / type B / type C” sub-grouping inside HMSN type 5. But doctors often talk about clinical patterns or variants based on what they see in real families: PubMed+2Springer Link+2

• Classic HMSN type 5 pattern
  In this pattern, people have slowly progressive weakness and wasting in the lower legs, high-arched feet, foot drop, mild sensory loss, and brisk reflexes. Spasticity is present but not very severe, and walking may stay possible for many years.

• HMSN type 5 with strong spastic paraplegia
  Some families show much stronger leg stiffness and spastic gait, almost like complicated hereditary spastic paraplegia, but they also have clear peripheral nerve damage. Reflexes are very brisk, and scissoring gait may appear.

• HMSN type 5 with mild neuropathy
  In some people, the pyramidal (spastic) signs are clear, but weakness from the neuropathy is mild. Nerve conduction tests may be near normal. These people may be mis-labelled as having “pure” hereditary spastic paraplegia at first.

• Autosomal dominant versus autosomal recessive forms
  Most families show autosomal dominant inheritance (one changed gene from one parent). A few reported families show autosomal recessive or more complex inheritance, often with earlier onset or extra brain changes.

• Overlap with hereditary spastic paraplegia gene types
  In some families with an HMSN type 5-like picture, gene testing finds changes in known HSP genes (for example, KIF5A / SPG10 or SPG11). The clinical picture is then described as “HSP with peripheral neuropathy (HMSN V phenotype)”. Thieme Connect+2ScienceDirect+2

Causes

Remember: this is an inherited disease. The basic cause is a change (mutation) in one of the genes that help long motor and sensory nerves, and sometimes the corticospinal tracts, to work properly. The 20 “causes” below are different ways of describing the genetic and biological reasons the disease appears or behaves in a person or family. PubMed+2Thieme Connect+2

1. Autosomal dominant gene mutation
   The main cause is a dominant mutation in a nerve-related gene. One copy of the gene from one parent is changed. This single changed copy is enough to disturb nerve function and cause neuropathy plus pyramidal signs.

2. Rare autosomal recessive inheritance
   In a few families, both parents are healthy carriers, each has one silent mutation. When a child receives both changed copies, they develop HMSN type 5-like symptoms. This recessive pattern is much less common but still described in medical literature. PubMed+1

3. New (de novo) mutation
   Sometimes the mutation arises for the first time in the egg or sperm, or very early after conception. In this case, there is no earlier family history, but the changed gene can be passed on to the next generation.

4. Mutations affecting axonal transport (for example KIF5A in some families)
   One study found a mutation in the KIF5A gene, which codes for a kinesin motor protein that carries cargo along the nerve axon. When this motor fails, long nerves in the legs degenerate, causing weakness and spastic signs. Thieme Connect+1

5. Mutations in hereditary spastic paraplegia genes (for example SPG11 in some families)
   Some HMSN V-like families map to genes usually linked with hereditary spastic paraplegia (such as SPG11). These genes are important for long pathways in the spinal cord and brain. When mutated, they can also affect peripheral nerves and produce the HMSN V picture. Thieme Connect+1

6. Degeneration of the corticospinal (pyramidal) tracts
   The corticospinal tracts are the “wires” carrying signals from the brain to the spinal cord. The genetic change leads to slow damage of these tracts, causing stiffness, brisk reflexes, and positive Babinski (extensor plantar) responses. MeSH Browser

7. Degeneration of long motor axons to the legs
   The same genetic fault also harms the long motor axons going from the spinal cord to the leg muscles. These axons are very long and fragile. Over time, they thin and break down, causing weakness and wasting in the feet and calves. Global Genes+1

8. Damage to sensory axons
   Sensory axons that carry feeling from the skin of the feet and legs can also be harmed. This leads to numbness, reduced vibration sense, or tingling. Sensory loss is sometimes mild or even absent, but it is part of the disease definition. Global Genes+1

9. Length-dependent nerve vulnerability
   Long nerves are more sensitive to defects in axonal transport and energy use. Because leg nerves are longest, they are usually affected first. This explains why symptoms begin in the feet and legs before the hands. Wikipedia+1

10. Progressive axonal loss with mostly preserved myelin
    In many HMSN type 5 cases, nerve conduction speed is near normal or only mildly changed, which suggests that axons are more damaged than the myelin sheath. Over time, loss of axons leads to reduced muscle control and strength. PubMed+1

11. Chronic denervation and re-innervation of muscles
    As motor axons die, muscle fibres lose their nerve supply (denervation). Surviving axons try to “rescue” neighbouring fibres. This repeated process makes muscles weaker and smaller, and EMG shows chronic neuropathic changes. Medscape eMedicine+1

12. Variable penetrance and expression
    The same mutation can cause different severity levels even inside one family. This is called variable penetrance and expression. It explains why some relatives have severe spasticity and weakness while others have only subtle signs. PubMed+1

13. Modifier genes
    Other genes in a person’s genome may make the neuropathy milder or more severe. These “modifier” genes do not cause HMSN type 5 by themselves, but they change how strongly the main mutation shows itself. (This is an active area of research in CMT and HSP.) PFM Journal+1

14. Age-related cumulative damage
    Because the genetic change is present from birth, damage builds up slowly over many years. This is why many people are normal in childhood, then develop symptoms in the teens or later. The longer the nerves work with a faulty protein, the more they wear out. PubMed+1

15. Cell stress and energy problems in nerve cells
    Many neuropathy and HSP genes are involved in cell transport, mitochondria, or membrane traffic. When these systems are disturbed, nerve cells experience chronic stress and cannot maintain long axons, leading to gradual nerve failure. PFM Journal+1

16. Impaired repair mechanisms in axons
    Healthy nerves can repair small injuries. In HMSN type 5, the mutated proteins may weaken this repair ability. Minor everyday stresses then cause more permanent damage than they would in a healthy nerve.

17. Possible effect of consanguinity in recessive families
    In rare recessive forms, if parents are related (for example, cousins), the chance that both carry the same rare mutation is higher. This makes it more likely that a child gets two changed copies and develops the disease. (This is a general rule for recessive diseases, not unique to HMSN V.)

18. X-linked or other complex inheritance in look-alike conditions
    Some CMT and spastic paraplegia types are X-linked or have complex inheritance and can present in similar ways (optic atrophy, deafness, neuropathy). Doctors must separate these from “true” HMSN type 5 using detailed gene testing. NCBI+1

19. Unknown gene defects not yet identified
    In many families with a clear HMSN V-like pattern, current gene panels still do not find the exact mutation. This means there are still unknown genes or gene regions involved that research has not fully mapped yet. PubMed+1

20. Epigenetic and environmental modifiers (worsening, not primary cause)
    While the core disease is genetic, things like illness, poor general health, or lack of exercise may worsen weakness or spasticity. They do not cause HMSN type 5 by themselves, but they may influence how disabled someone becomes.

Symptoms

Below are 15 main symptoms and signs. Not every person has all of them, and severity can be very different between people and even within one family. Global Genes+2Genetic and Rare Diseases Center+2

1. Slowly progressive weakness in the feet and lower legs
   This is usually the first problem. People feel that their feet and ankles are weak. Climbing stairs, running, or standing on tip-toes becomes hard. Over years, the weakness slowly increases.

2. Muscle wasting in the calves and feet
   Because nerves do not fully reach the muscles, the muscles become small and thin (atrophy). The lower legs may look like an “inverted champagne bottle” – thin below the knee with relatively normal thighs.

3. Difficulty walking and frequent tripping
   Weak ankle and toe muscles cause foot drop. The front of the foot cannot lift properly during walking. This leads to tripping on low obstacles, uneven ground, or stairs. People may have to watch their feet while walking.

4. High-arched feet (pes cavus) and other foot deformities
   Imbalance between weak and strong muscles in the feet pulls the arch higher. Toes may curl into “claw toes”. These deformities make shoe fitting difficult and can cause pressure points and pain. Global Genes+2Wikipedia+2

5. Spasticity (stiff, tight leg muscles)
   Because the corticospinal tracts are affected, leg muscles may become stiff and resist movement. This is called spasticity. It can make walking feel jerky or “robot-like” and can cause muscle spasms, especially in cold or stress. MeSH Browser

6. Brisk tendon reflexes and extensor plantar responses
   When the doctor taps the knee or ankle, the reflex jump may be very strong. The Babinski test (stroking the sole of the foot) may show upward movement of the big toe (extensor plantar response). These are typical upper-motor-neuron signs. Global Genes+2Genetic and Rare Diseases Center+2

7. Spastic or mixed gait pattern
   Some people develop a spastic gait, with stiff legs and reduced knee bending. Others show a mix of high-stepping (from foot drop) and scissoring or stiff movement (from spasticity). This combination is very characteristic of HMSN type 5. PubMed+1

8. Sensory loss in the feet and lower legs
   There can be reduced feeling for vibration, light touch, or position in the toes and feet. Sometimes pain and temperature sensation are also mildly affected. In some patients, sensory loss is very mild or absent. Global Genes+1

9. Numbness, tingling, or burning feelings
   Some people feel pins-and-needles, tingling, or burning pain in their feet and legs. These symptoms come from damaged sensory axons and may get worse after long standing or at night.

10. Muscle cramps and spasms
    Cramps in the calves or feet, especially at night or after activity, are common. Spasticity and chronic nerve irritation both increase the chance of painful muscle tightening. Global Genes+1

11. Balance problems and unsteady walking
    Weakness, foot deformities, and reduced sensation in the feet make balance harder. Walking in the dark or on uneven ground can be risky. Falls may happen, especially in later stages.

12. Fatigue and reduced endurance
    Walking takes more effort when muscles are weak and stiff. People tire easily, need frequent rests, and may avoid long distances or stairs, even if they are still able to walk independently.

13. Mild hand weakness in some cases
    Although the disease mainly affects the legs, some people later develop weakness in hand muscles. This makes fine tasks like buttoning clothes or opening jars more difficult, similar to other CMT types. Wikipedia+1

14. Foot pain and joint discomfort
    Abnormal foot shape and altered walking place extra stress on joints and ligaments. This can cause aching in the feet, ankles, knees, or hips, especially after long periods of standing or walking.

15. Psychological impact (worry, low mood, social limits)
    Chronic disease, fear of falling, and visible gait changes may lead to anxiety, embarrassment, or low mood. This is not a direct nerve symptom, but it is an important part of the total illness burden. Support and counselling can help.

Diagnostic tests

Below are tests, grouped inside this section as physical exam, manual tests, lab and pathological tests, electrodiagnostic tests, and imaging tests. Springer Link+3Medscape eMedicine+3PFM Journal+3

1. Complete neurological physical exam
   The neurologist checks strength, reflexes, muscle tone, sensation, coordination, and cranial nerves. In HMSN type 5, they often find distal leg weakness and wasting, brisk reflexes, increased tone in the legs, and sometimes mild sensory loss in the feet.

2. Observation of gait and posture
   The doctor watches how the person walks across the room. They look for foot drop, high-stepping gait, spastic or stiff movements, and difficulty turning or walking on heels or toes. This gives strong clues about both neuropathy and pyramidal involvement.

3. Foot and leg inspection
   The feet and legs are examined for high arches, claw toes, calluses, and calf wasting. The doctor also checks for contractures, ankle range of motion, and leg length or posture differences.

4. Detailed sensory examination
   Light touch, pinprick, vibration (with a tuning fork), and joint position sense are tested in the toes, feet, and legs. Reduced vibration and position sense in the feet support the diagnosis of a length-dependent sensory neuropathy.

5. Manual muscle testing (strength grading)
   The doctor or physiotherapist presses against different muscle groups and grades strength (for example, using the MRC scale 0–5). Weakness is usually worst in ankle dorsiflexors and toe extensors; proximal hip muscles may be relatively preserved.

6. Heel-walking and toe-walking test
   The person is asked to walk on heels and then on toes. Difficulty walking on heels suggests weak ankle dorsiflexors (foot-lifting muscles). Difficulty walking on toes suggests weak calf muscles. These simple bedside tests highlight distal weakness.

7. Romberg test for balance
   The patient stands with feet together, arms by the side, first with eyes open, then eyes closed. Swaying or falling with eyes closed suggests poor position sense in the feet, which can happen in sensory neuropathy.

8. Spasticity assessment (for example, modified Ashworth-type scale)
   The doctor moves the patient’s legs and feels how much resistance there is. A “clasp-knife” feel or velocity-dependent resistance points to spasticity. Rating scales help track changes over time or with treatment.

9. Routine blood tests to exclude other neuropathies
   Blood tests (for diabetes, vitamin B12, thyroid function, kidney and liver function, autoimmune markers) are often normal in HMSN type 5, but they are important to rule out acquired neuropathies that might mimic or worsen the picture. Medscape eMedicine+1

10. Genetic testing panels for CMT / HSP genes
    Modern panels test many genes linked with CMT and hereditary spastic paraplegia. In HMSN type 5-like cases, testing may find mutations in genes such as KIF5A or SPG11, or may show a variant of unknown significance. Even if no mutation is found, a genetic test can still support an inherited pattern when combined with family history. Thieme Connect+2PubMed+2

11. Targeted or whole-exome / whole-genome sequencing
    If panel testing is negative but suspicion is high, more advanced sequencing may be used, especially in research settings. These methods scan many genes at once and sometimes discover new disease genes in rare families.

12. Nerve conduction studies (NCS)
    Electrodes are placed on the skin over nerves. Small electrical shocks measure how fast and how strong signals travel. In HMSN type 5, conduction speed is often near normal or only slightly reduced, but response sizes may be low, consistent with axonal neuropathy rather than strong demyelination. PubMed+2Springer Link+2

13. Electromyography (EMG)
    A thin needle electrode is placed into muscles to record their electrical activity. EMG in HMSN type 5 typically shows signs of chronic denervation and re-innervation (large motor units, reduced recruitment), confirming a long-standing neuropathic process. Medscape eMedicine+1

14. Evoked potentials for corticospinal tracts
    Motor evoked potentials (MEPs) and somatosensory evoked potentials (SSEPs) can test how well signals pass along the central motor and sensory pathways. Delays in these tests support involvement of the pyramidal system in addition to peripheral nerves. MeSH Browser

15. MRI of the brain
    Brain MRI is usually normal or shows only subtle findings, but it helps rule out other causes of spasticity (such as stroke, structural brain lesions, or multiple sclerosis). In some recessive or complicated forms, corpus callosum thinning or other changes may be seen. Thieme Connect+1

16. MRI of the spinal cord
    MRI of the cervical and thoracic spinal cord can exclude structural cord compression (for example, cervical myelopathy) that could look similar to hereditary spastic paraplegia. It also helps the doctor feel confident that the spasticity is from a hereditary process.

17. MRI or ultrasound of peripheral nerves (in selected cases)
    High-resolution imaging of nerves can sometimes show subtle changes in nerve size or structure. This is more experimental but can be helpful in difficult diagnostic cases or research.

18. X-rays of feet and spine
    Simple X-rays can document high arches, claw toes, and spinal deformities (such as scoliosis or increased lumbar lordosis). This is useful for planning orthopaedic treatment and tracking progression. Wikipedia+1

19. Muscle biopsy (rarely needed now)
    In the past, doctors sometimes biopsied muscles to distinguish neuropathic from muscle disease. Today, EMG and genetics are usually enough, so biopsy is reserved for unusual or unclear cases. When done, the biopsy shows changes typical of chronic denervation. PFM Journal

20. Sural nerve biopsy (only in complex or uncertain cases)
    A small sensory nerve near the ankle is removed and studied under the microscope. Reports in HMSN V show mostly axonal loss with relatively preserved myelin and no classic “onion bulbs”, but findings can vary. Because biopsy is invasive and genetics is improving, it is now used much less often. Springer Link+1

Non-pharmacological treatments

These therapies do not use medicines. They help you keep strength, balance, and independence. For this disease, international experts say that rehabilitation and regular follow-up are the main pillars of care. MDPI+4ScienceDirect+4PMC+4

1. Individualized physical therapy
Physical therapy is a long-term exercise program planned by a trained therapist. The therapist checks your muscle strength, balance, flexibility, and walking style. Then they design gentle exercises to keep your muscles working as well as possible without over-fatiguing them. Early and regular physical therapy can slow loss of mobility and improve balance, which lowers the chance of falls and injuries in people with CMT-type neuropathies.

2. Occupational therapy for daily activities
Occupational therapists help you do everyday tasks like dressing, cooking, writing, and computer work in an easier, safer way. They may suggest special tools such as built-up pens, adapted cutlery, or button hooks. They also teach energy-saving tricks, like sitting instead of standing for tasks. This support protects your joints and nerves from extra stress, and lets you stay independent for as long as possible. Charcot-Marie-Tooth Association+1

3. Strengthening exercises for weak muscles
Gentle, supervised strengthening exercises focus on muscles around the ankles, knees, hips, and hands. The goal is not to build big muscles but to maintain functional strength. Too-hard exercise can actually tire fragile nerves, so the therapist uses low resistance and frequent rest breaks. Studies in CMT show that correctly dosed strengthening can help mobility without worsening nerve damage. Pod NMD+1

4. Stretching to prevent contractures
Because the muscles in the feet and legs are weak, tightness in tendons and joints can develop over time. Daily stretching of calves, hamstrings, and feet keeps joints moving well and can delay fixed deformities like toe clawing. Stretching is often done gently for 20–30 seconds per muscle, repeated several times, and combined with warm packs or a warm bath to relax tight tissues.

5. Balance and gait training
HMSN type 5 can cause poor balance and “foot slap” or foot drop while walking. In balance and gait training, therapists use exercises like standing on different surfaces, stepping over small obstacles, and practicing turning safely. They may use parallel bars or harness systems. Over time, this helps the brain and body work together better, so you walk more safely and confidently with fewer falls. MDPI+1

6. Orthotic devices (AFOs and foot orthoses)
Ankle–foot orthoses (AFOs) and custom insoles support weak ankles and high-arched or unstable feet. They hold the foot in a better position, reduce foot drop, and make walking smoother with less effort. They also lower the risk of twisting an ankle. Evidence in CMT shows that AFOs can improve walking speed, reduce tripping, and lessen abnormal compensating movements in the hips and knees. Charcot-Marie-Tooth Disease+2Pod NMD+2

7. Special footwear
People with pes cavus or other foot deformities often need extra-depth shoes with soft uppers and strong soles. Footwear may include rocker-bottom soles or custom inserts to spread body weight more evenly. Proper shoes protect pressure points and reduce the chance of skin breakdown and ulcers, which can happen because of reduced feeling in the feet. Cleveland Clinic+1

8. Walking aids (canes, walkers, wheelchairs)
Some people will, over time, need a cane, crutch, walker, or wheelchair for longer distances. This is not a failure. These aids save energy, lessen pain and fatigue, and prevent falls. They can also allow you to keep working, studying, or joining family trips safely, even if your leg strength declines. A therapist can teach correct sizing and use so that shoulders and wrists are not harmed.

9. Hand therapy and fine-motor training
If hand weakness or stiffness develops, hand therapists can teach special exercises and provide hand splints. They focus on grip strength, pinch strength, and coordination. Simple tasks like picking up coins, squeezing therapy putty, or using hand exercisers can be adapted to your abilities. This helps with writing, phone use, and self-care tasks. Charcot-Marie-Tooth Association+1

10. Respiratory and posture management
Most people with HMSN type 5 do not get severe breathing problems, but posture can still be affected. Breathing exercises and good sitting and standing posture reduce back pain and help the lungs expand fully. For those with more advanced disease, doctors may monitor lung function and suggest simple breathing devices, particularly at night.

11. Pain psychology and cognitive-behavioural therapy (CBT)
Chronic neuropathic pain can be stressful and exhausting. CBT teaches simple mental skills to reduce the emotional impact of pain, such as reframing thoughts, relaxation, and pacing. These strategies do not replace medicine but can lower distress and help people feel more in control of their symptoms and daily life. Charcot-Marie-Tooth Association+1

12. Fatigue management and energy conservation
Because the nerves and muscles work less efficiently, many people feel tired easily. Therapists teach pacing, planning rest breaks, and doing the hardest tasks at the time of day when you feel strongest. Using wheeled bags instead of carrying heavy loads or sitting for tasks instead of standing are simple examples. These habits reduce fatigue and protect joints.

13. Fall-prevention home modifications
Removing loose rugs, improving lighting, using grab bars in bathrooms, and adding railings on stairs all reduce fall risk. Simple changes like keeping pathways clear and using non-slip mats make a big difference when ankle strength and balance are poor. Such home safety plans are standard parts of CMT care. Cleveland Clinic+1

14. Vocational rehabilitation and school support
Vocational specialists help match your abilities with suitable work or training. They may suggest ergonomic desks, speech-to-text software, flexible hours, or mixed in-person/remote working. For students, school accommodations such as extra time in exams or laptop use for writing can keep education on track.

15. Speech and swallowing therapy (if pyramidal features are marked)
A small group of people with HMSN type 5 have more obvious “pyramidal” features affecting upper-body muscles. If speech or swallowing becomes difficult, a speech-language therapist can assess this and teach exercises and safe swallowing techniques. This might include adjusting food textures or learning new ways to speak clearly without exhausting the voice. Genetic and Rare Diseases Center+1

16. Hydrotherapy (water-based exercise)
Exercising in warm water supports the body and reduces the effect of gravity on weak legs and feet. This allows gentle walking, stepping, and stretching that may be too hard on land. The warm water also relaxes tight muscles and joints and can improve comfort for a few hours after the session.

17. Transcutaneous electrical nerve stimulation (TENS)
TENS uses small pads on the skin to deliver a weak electrical current. Some people with neuropathic pain in CMT report short-term relief with TENS. The device is usually used together with medicines and physical therapy. Evidence is mixed, but because it is low-risk when used correctly, doctors may allow a trial under guidance. PMC+1

18. Patient education and self-management training
Good information helps you make better daily decisions. Education covers foot care, warning signs of skin problems, how to choose activities, and how to work with your healthcare team. CMT organizations publish easy-to-read booklets and online guides that people with HMSN can use to support self-care. Mayo Clinic+2PMC+2

19. Genetic counselling
Because HMSN type 5 is hereditary, genetic counsellors explain how the condition is passed in families and discuss testing options. They can support people planning a family, talk about prenatal or pre-implantation genetic testing where available, and help family members decide if they want to be tested. NCBI+1

20. Peer support groups and psychological counselling
Living with a long-term nerve disease can cause worry, low mood, or social isolation. Support groups (online or in person) and counselling give a safe place to talk about fears and share coping ideas. Research in chronic neurological disease shows that such support improves quality of life and can reduce feelings of loneliness and depression. PMC+2PMC+2

Drug treatments

Very important: there is no medicine approved specifically to cure hereditary motor and sensory neuropathy type 5. Treatment uses drugs that are approved for other causes of neuropathic pain, spasticity, depression, or sleep problems, and doctors may use them “off-label” for symptoms in CMT and related neuropathies. Never start, stop, or change any dose without your doctor. Brieflands+3ScienceDirect+3Charcot-Marie-Tooth Association+3

Below, dosages are typical adult label ranges from FDA documents for the main approved indication (such as diabetic nerve pain). They are educational examples only, not personal prescriptions. FDA Access Data+4FDA Access Data+4FDA Access Data+4

1. Gabapentin (Neurontin and others)
Class: Antiepileptic / gabapentinoid. Typical adult dosage: Many labels use 900–3600 mg per day in divided doses for neuropathic pain; doctors start low and increase slowly. FDA Access Data+3FDA Access Data+3FDA Access Data+3 Purpose: To reduce burning, stabbing, or electric-shock-like nerve pain. Mechanism: It binds to a calcium-channel subunit in nerve cells, which reduces release of pain-signalling chemicals. Common side effects: Sleepiness, dizziness, swelling of ankles, weight gain, and sometimes mood changes or suicidal thoughts as warned in FDA labels.

2. Pregabalin (Lyrica)
Class: Antiepileptic / gabapentinoid. Typical adult dosage: FDA labels for diabetic neuropathy often start at 150 mg/day and may increase to 300–600 mg/day in divided doses, depending on kidney function. FDA Access Data+3FDA Access Data+3FDA Access Data+3 Purpose: To treat neuropathic pain and sometimes sleep problems linked to pain. Mechanism: Similar to gabapentin, it reduces abnormal nerve firing. Common side effects: Dizziness, drowsiness, weight gain, swelling, blurred vision; labels also warn about suicidal thoughts and allergic reactions.

3. Duloxetine (Cymbalta)
Class: Serotonin–norepinephrine reuptake inhibitor (SNRI) antidepressant. Typical adult dosage: For diabetic neuropathic pain, labels commonly use 60 mg once daily. FDA Access Data+3FDA Access Data+3FDA Access Data+3 Purpose: To relieve neuropathic pain and treat depression or anxiety if present. Mechanism: Increases serotonin and norepinephrine in pain-modulating pathways in the brain and spinal cord. Common side effects: Nausea, dry mouth, sleepiness or insomnia, sweating, constipation, and small blood pressure changes; labels warn about suicidal thoughts in younger people and rare liver problems.

4. Amitriptyline
Class: Tricyclic antidepressant (TCA). Typical adult dosage: Many neuropathic pain guidelines begin at 10–25 mg at night and slowly increase up to about 75–100 mg/day if tolerated. Brieflands+2Springer Link+2 Purpose: To treat chronic nerve pain and help sleep. Mechanism: Blocks reuptake of serotonin and norepinephrine and may block certain pain pathways in the spinal cord. Common side effects: Dry mouth, constipation, blurred vision, weight gain, drowsiness; in some people, heart rhythm changes and confusion, especially in older adults.

5. Nortriptyline
Class: Tricyclic antidepressant. Typical adult dosage: Often started at 10–25 mg at bedtime and adjusted according to response. Purpose: Similar to amitriptyline but sometimes better tolerated. Mechanism and side effects: Like amitriptyline, but often with slightly fewer sedating or anticholinergic effects; still can cause dry mouth, dizziness, and heart rhythm changes, so ECG checks may be needed in some patients. Springer Link+1

6. Venlafaxine extended-release
Class: SNRI antidepressant. Typical adult dosage: For depression and anxiety, labels usually start at 75 mg/day and may go higher; for neuropathic pain, similar ranges are used in studies under specialist supervision. Purpose: To treat neuropathic pain plus depression or anxiety. Mechanism: Increases serotonin and norepinephrine signalling in pain pathways. Common side effects: Nausea, sweating, sleep changes, increased blood pressure at higher doses; labels warn about suicidal thoughts in youth and withdrawal symptoms if stopped suddenly. Brieflands+1

7. Topical lidocaine 5% patches
Class: Local anaesthetic. Typical adult dosage: Patch applied to painful area for up to 12 hours on, 12 hours off, as per label for post-herpetic neuralgia; number of patches depends on area and doctor’s advice. Purpose: To numb localized burning or allodynia (pain from light touch). Mechanism: Blocks sodium channels in nerve endings in the skin, stopping pain signal generation. Side effects: Local skin irritation, redness, or rash; systemic side effects are rare when used correctly. Brieflands+1

8. Topical capsaicin cream or high-strength patches
Class: TRPV1 receptor agonist (from chili pepper). Purpose: To reduce small-fiber nerve pain in localized areas. Mechanism: Repeated stimulation of pain fibres causes temporary “defunctioning” of those endings, so they send fewer pain signals. Dosage and timing: Low-strength cream is rubbed on several times per day; high-dose patches are applied in clinic at long intervals. Side effects: Burning, redness, or stinging at the site; usually lessen with time. Brieflands+1

9. Baclofen (oral or intrathecal)
Class: GABA-B agonist muscle relaxant and antispastic medicine. Typical adult dosage: Oral labels often start at low doses (5–10 mg three times daily) and increase slowly as needed for spasticity from multiple sclerosis or spinal cord injury. FDA Access Data+4FDA Access Data+4FDA Access Data+4 Purpose: To reduce muscle stiffness and spasms in people with strong pyramidal features. Mechanism: Activates GABA-B receptors in the spinal cord, reducing excitatory signals to muscles. Common side effects: Drowsiness, dizziness, weakness; sudden withdrawal can cause serious reactions, so doses must be reduced slowly under medical supervision.

10. Tizanidine
Class: Alpha-2 adrenergic agonist muscle relaxant. Purpose: To treat muscle spasms and stiffness. Mechanism: Reduces release of excitatory transmitters in spinal pathways. Dosage: Usually started at low doses several times per day and adjusted individually. Side effects: Sleepiness, low blood pressure, dry mouth, and liver enzyme changes, so blood tests may be needed.

11. NSAIDs (e.g., ibuprofen, naproxen)
Class: Non-steroidal anti-inflammatory drugs. Purpose: To relieve mild musculoskeletal pain, joint strain, or post-surgical discomfort. Mechanism: Block COX enzymes and reduce prostaglandin production, lowering inflammation and pain. Dosage: Label doses vary by drug and age; must follow package or doctor instructions carefully. Side effects: Stomach upset, ulcers, kidney effects, and increased bleeding risk with long-term or high-dose use.

12. Acetaminophen (paracetamol)
Class: Analgesic and antipyretic. Purpose: For mild aches and pains when NSAIDs are not suitable. Mechanism: Acts on central nervous system pain pathways (exact mechanism not fully known). Dosage: Strict maximum daily dose on label must not be exceeded to avoid liver damage. Side effects: Usually mild at normal doses, but overdose can cause severe liver failure; must not combine multiple acetaminophen-containing products.

13. Tramadol (cautious use only)
Class: Weak opioid and SNRI-like analgesic. Purpose: For moderate neuropathic pain not controlled by other drugs, and usually short-term. Mechanism: Acts on opioid receptors and inhibits serotonin and norepinephrine reuptake. Side effects: Nausea, dizziness, constipation, dependence, and risk of serotonin syndrome or seizures; because of these risks, especially in young people, it is used carefully and only by specialist doctors. Brieflands+1

14. Opioid analgesics (last-line only)
Class: Strong opioid pain relievers (such as morphine or oxycodone). Purpose: Reserved for severe pain crisis when other options fail, often short-term or in palliative care. Mechanism: Bind to opioid receptors in brain and spinal cord to reduce pain perception. Side effects: High risk of dependence, overdose, constipation, drowsiness, and breathing suppression; not a routine choice in CMT and used under strict specialist control only. SciSpace+1

15. Clonazepam or similar benzodiazepines (specialist use)
Class: Benzodiazepine. Purpose: Sometimes used for severe restless legs, cramps, or anxiety. Mechanism: Enhances GABA-A signalling, providing sedative and muscle-relaxant effects. Side effects: Drowsiness, dependence, withdrawal symptoms; generally avoided for long-term use and used only when clearly needed.

16. SSRIs or SNRIs for mood (e.g., sertraline, additional use of duloxetine)
Class: Antidepressants. Purpose: To treat depression and anxiety related to chronic illness, which can make pain feel worse. Mechanism: Adjust serotonin (and sometimes norepinephrine) levels in the brain. Side effects: Depend on the drug, but can include nausea, sleep changes, and sexual side effects; labels also carry suicide risk warnings in younger patients. PMC+2FDA Access Data+2

17. Sleep medicines (short course, if needed)
Low-dose sedating antidepressants or other prescribed sleep aids may be used for short periods when pain severely disrupts sleep. Doctors choose the safest option depending on other conditions. Long-term sleeping pills are usually avoided because of dependence and poor long-term benefit. Good sleep hygiene is always the first step.

18. Antispasmodic drugs other than baclofen (e.g., diazepam – highly cautious)
In some cases of marked spasticity, other muscle relaxants may be tried. However, many, like diazepam, carry a high risk of sedation and dependence, so they are reserved for very specific situations and under close monitoring.

19. Topical NSAID gels
For localized joint or tendon pain (for example around deformed feet), topical NSAID gels can give local relief with less whole-body exposure than oral tablets. They are rubbed on the painful area, following label instructions. Skin irritation is the main side effect.

20. Off-label agents in research (e.g., sodium channel blockers like lamotrigine)
Some sodium channel blocker drugs have been studied for neuropathic pain in other conditions. They reduce abnormal firing of sensory nerves. Evidence is mixed, and side effects, including rash or serious skin reactions, limit use. For HMSN type 5, these drugs would be considered only by specialists after careful risk–benefit discussions.

Dietary molecular supplements

There is no supplement proven to cure HMSN type 5, but some nutrients may support general nerve health when used with medical care. Always ask your doctor before starting any supplement, especially if you take prescription medicines. NCBI+2Physiopedia+2

1. Vitamin B1 (thiamine)
Thiamine is important for energy production in nerve cells. Long-term lack of B1 can cause nerve damage. A typical supplement dose is often 10–50 mg/day in multivitamin or B-complex form, but exact doses depend on diet and medical advice. It may support nerve metabolism but does not reverse inherited genetic defects. Too-high doses can cause stomach upset in some people.

2. Vitamin B6 (pyridoxine)
B6 helps in producing neurotransmitters. Mild deficiency may worsen nerve symptoms, but very high doses can themselves cause nerve damage. Doctors usually keep total daily intake within safe limits (for example under about 100 mg/day in adults). Used carefully, B6 may support nerve function as part of a balanced B-complex supplement.

3. Vitamin B12 (cobalamin)
B12 is essential for myelin, the protective sheath around nerves. Deficiency can cause neuropathy that mimics or worsens hereditary forms. Standard supplement doses vary widely (for example 250–1000 micrograms/day), especially in people with poor absorption. Correcting low B12 can improve sensation and balance if deficiency is present, but will not cure the genetic neuropathy itself. NCBI+1

4. Folate (vitamin B9)
Folate works with B12 in nerve and blood cell health. Low folate can contribute to neuropathy and fatigue. Supplements are often 400–800 micrograms/day in adults, adjusted for pregnancy or other conditions. It should be used under medical advice because high folate can hide B12 deficiency, delaying diagnosis.

5. Vitamin D
Vitamin D is important for bone and muscle strength. People with mobility problems often have low vitamin D levels because they spend less time in sunlight. Supplements are usually dosed according to blood tests. Correct vitamin D levels help reduce falls and fractures, indirectly supporting mobility in people with neuropathies.

6. Vitamin E
Vitamin E is an antioxidant and deficiency can cause nerve problems in rare conditions. Supplement doses vary; high doses may affect blood clotting, especially with blood-thinning medicines. In hereditary neuropathies, vitamin E is mainly used if a deficiency is proven. It may help protect cell membranes but cannot fix the underlying gene change.

7. Alpha-lipoic acid
Alpha-lipoic acid is an antioxidant studied in diabetic neuropathy. Some trials show modest improvements in pain and nerve function, especially with intravenous forms, but data are mixed. Typical oral supplement doses in studies have been 300–600 mg/day. It may support nerve energy metabolism; side effects can include gastrointestinal upset and low blood sugar in some people. Brieflands+1

8. Omega-3 fatty acids (fish-oil or algae-oil)
Omega-3 fats support cell membranes and may have mild anti-inflammatory effects. Supplements often provide 500–1000 mg/day or more of EPA + DHA, but doses should be individualized. They may slightly improve cardiovascular health and general well-being. Side effects can include fishy aftertaste and, at high doses, increased bleeding tendency.

9. Coenzyme Q10 (CoQ10)
CoQ10 helps mitochondria (energy factories) in cells. Some small studies in neuromuscular diseases suggest possible benefit, but evidence is limited. Common supplement doses range from 100–300 mg/day. It may help reduce fatigue in some people but is not a disease-modifying treatment for HMSN type 5.

10. Acetyl-L-carnitine
Carnitine helps move fatty acids into mitochondria for energy production. Studies in some neuropathies show small improvements in nerve regeneration and pain, but results are mixed. Typical supplement doses in research have been around 500–1500 mg/day. Side effects can include gastrointestinal symptoms and fishy body odour.

Regenerative, immunity-booster, and stem-cell-related drugs

For hereditary motor and sensory neuropathy type 5, there are currently no approved immune-booster drugs, regenerative drugs, or stem cell drugs that reliably cure or reverse the disease. Research is ongoing in CMT in general. Treatment in this area should only occur inside well-controlled clinical trials. ScienceDirect+2NCBI+2

Below are research directions, not recommended self-treatments:

1. Gene-targeted therapies – Scientists are exploring gene therapy to correct or silence faulty genes in certain CMT types. This may involve viral vectors delivering healthy gene copies. None are yet standard care for HMSN type 5.

2. Neurotrophic growth factors – Experimental drugs that mimic nerve growth factors aim to support axon survival and regrowth. Past trials in CMT showed mixed or limited benefit, and side effects have been a problem.

3. Stem cell transplantation (experimental) – Some research looks at transplanting stem cells to support nerve repair, but this remains early-stage and is not a routine or proven treatment for hereditary neuropathies. Risks include immune reactions and tumour formation.

4. Small-molecule modifiers of myelin/axon biology – Certain compounds are being studied to correct cellular stress in Schwann cells or axons in CMT. So far, no medication from this group has become standard care.

5. Immune-modulating therapies – Immunoglobulin or steroids are helpful in immune neuropathies like CIDP, but hereditary motor and sensory neuropathy type 5 is not primarily immune-mediated. These therapies are not usually helpful here and may cause serious side effects.

6. Combination rehabilitation plus biological therapies – Future trials may mix biological treatments with intensive rehabilitation. At present, the proven part is the rehabilitation; the biological therapies are still under investigation.

Surgical options

Surgery does not cure HMSN type 5 but can correct or improve deformities caused by long-term muscle imbalance. It is usually planned by a specialist orthopaedic surgeon with experience in neuromuscular conditions. Cleveland Clinic+2Radiopaedia+2

1. Foot deformity correction (osteotomies)
High-arched feet, claw toes, and heel deformities can make walking painful and unstable. Surgeons can cut and reshape bones in the foot (osteotomy) to create a more balanced shape. This improves weight distribution, reduces calluses and ulcers, and can make it easier to fit shoes and braces.

2. Tendon transfer surgery in the foot and ankle
Because some muscles become weak and others stay strong, muscles pull unevenly on the bones. In tendon transfer surgery, a stronger tendon is moved to take over the job of a weaker one (for example to reduce foot drop). This can improve active lifting of the foot and help walking, especially when combined with good rehab.

3. Achilles tendon lengthening
If the calf muscles are tight, the heel may not come fully to the ground. Lengthening the Achilles tendon allows the foot to rest more flatly, improving balance and reducing pressure on the toes and forefoot. It can also make AFO fitting easier.

4. Hand surgery for deformities
In some people, finger deformities or thumb weakness interfere with grip. Hand surgeons can correct joint positions or perform tendon transfers to improve pinch and grasp. This aims to restore practical hand function for key tasks, not perfect cosmetic appearance.

5. Spine and lower-limb alignment surgery
In more severe cases, long-term imbalance can affect the knees, hips, or spine (for example, scoliosis). Corrective surgery aims to realign bones and joints to a more natural position. This can relieve pain, improve sitting or standing posture, and sometimes slow further deformity.

Prevention and self-care

You cannot prevent the genetic cause of HMSN type 5, but you can reduce complications and slow secondary damage: PMC+4Mayo Clinic+4Cleveland Clinic+4

1. Regular follow-up with neurology and rehab teams to adjust therapies, braces, and medicines as the disease slowly changes.

2. Daily skin and foot checks to spot blisters, cuts, or pressure areas early, because reduced feeling means injuries may go unnoticed.

3. Use of proper footwear and orthoses to support feet and protect skin and joints.

4. Safe, regular low-impact exercise (walking, swimming, cycling as tolerated) to maintain fitness without over-straining weak muscles.

5. Avoiding heavy lifting and high-impact sports that stress unstable joints and increase fall risk.

6. Keeping a healthy weight, as extra body weight stresses weak muscles and increases pain and fatigue.

7. Avoiding neurotoxic drugs and toxins (for example, some chemotherapy drugs or excessive alcohol) that can worsen neuropathy; your doctor can review your medicine list.

8. Good control of other health problems, such as diabetes or thyroid disease, which can add extra nerve damage.

9. Early treatment of infections or injuries in the feet or legs, to prevent ulcers and serious complications.

10. Psychological support and stress management, which can reduce pain perception and improve day-to-day coping.

When to see doctors

You should see a doctor or your neuromuscular team if:

• You notice new or rapidly worsening weakness, balance problems, or falls.

• You develop sudden severe pain, burning, or electric-shock sensations that do not settle.

• You see sores, blisters, colour changes, or swelling in your feet or legs that do not heal quickly.

• Your braces or shoes cause new pressure marks, redness, or pain.

• You develop breathing problems, severe fatigue, trouble swallowing, or sudden changes in speech.

• You feel very low, hopeless, or have thoughts of harming yourself; this can be a side effect of pain medicines or depression itself, and needs urgent help. FDA Access Data+4Mayo Clinic+4Cleveland Clinic+4

Regular planned check-ups (for example once or twice a year) are also important, even if symptoms seem stable. They allow early adjustment of therapies and braces before problems become severe.

What to eat and what to avoid

Food cannot cure HMSN type 5, but a balanced diet supports muscles, nerves, bones, and overall health. NCBI+2Physiopedia+2

Helpful to eat:

1. Plenty of colourful vegetables and fruits – provide antioxidants, vitamins, and fibre for general health and inflammation control.

2. Lean proteins such as fish, eggs, beans, and pulses – supply amino acids for muscle repair and immune function.

3. Healthy fats from nuts, seeds, olive oil, and fish – provide omega-3 and other good fats that support cell membranes.

4. Whole grains like brown rice and oats – give steady energy and help maintain a healthy weight.

5. Calcium- and vitamin-D-rich foods such as dairy or fortified products – support bones that carry weakened muscles.

Best to limit or avoid:

6. Sugary drinks and ultra-processed snacks, which add calories without nutrients and can worsen weight gain and fatigue.

7. Excessive saturated and trans fats (deep-fried foods, some fast foods), which may harm heart health and add inflammation.

8. High-salt foods, especially if you have high blood pressure or swelling; many processed foods are very salty.

9. Excess alcohol, which can directly worsen nerve damage and interact with medicines used for neuropathic pain.

10. Unregulated “miracle” supplements or mega-doses of vitamins promoted online; these can waste money and sometimes harm the liver, kidneys, or nerves. Always discuss new supplements with your doctor.

Frequently asked questions (FAQs)

1. Is hereditary motor and sensory neuropathy type 5 the same as Charcot–Marie–Tooth disease?
Yes. HMSN type 5 is one specific form of Charcot–Marie–Tooth disease, a group of inherited nerve disorders. It mainly affects the long nerves to the legs and sometimes the arms, and often includes “pyramidal” signs like brisk reflexes. Genetic and Rare Diseases Center+2Orpha.net+2

2. What causes this disease?
It is caused by changes (mutations) in certain genes that are important for nerve function. These changes are present from birth and usually inherited from one or both parents, although sometimes they appear “new” in one person. The exact gene can vary, and genetic testing may help identify it.

3. Can I catch it from someone else?
No. It is not an infection and cannot spread from person to person. It is purely genetic.

4. At what age do symptoms usually appear?
Symptoms often start in childhood, teen years, or early adulthood, but the exact age can vary even within the same family. Some people notice problems later, such as in mid-life, especially when demands on the body increase. Mayo Clinic+1

5. Will I end up in a wheelchair?
Not everyone does. HMSN type 5 usually progresses slowly. Some people may need a wheelchair for longer distances as they get older, while walking short distances at home with braces or a cane. Good rehab, safe exercise, and early use of orthoses can help maintain walking for longer.

6. Is there any cure right now?
At present, there is no cure that removes the genetic problem. Treatment focuses on controlling symptoms, preventing complications, and keeping you as active and independent as possible. Researchers are working on gene-based and regenerative treatments, but these are still experimental. ScienceDirect+2Radiopaedia+2

7. Can exercise make my nerves worse?
Very hard or prolonged exercise that causes intense fatigue or pain can be harmful. However, carefully planned, low-to-moderate exercise under guidance is usually helpful. It keeps muscles, joints, and the heart healthier. The key is supervision by therapists who understand hereditary neuropathies and know how to avoid over-work. Physiopedia+2MDPI+2

8. Are pain medicines safe to use long-term?
Many neuropathic pain medicines can be used long-term, but they need regular monitoring because they may cause side effects like weight gain, drowsiness, mood changes, or, in the case of opioids and some others, dependence. Your doctor will usually start with safer first-line drugs and review them regularly.

9. Can this disease affect my breathing or heart?
Most people with HMSN type 5 mainly have leg and sometimes hand involvement. Rarely, more severe forms of CMT can affect breathing muscles or cause scoliosis that troubles the lungs. Routine check-ups allow early detection. The heart itself is usually not directly affected by HMSN type 5, but general health must still be monitored. Mayo Clinic+2Cleveland Clinic+2

10. Can women with HMSN type 5 have children safely?
Many women with CMT have successful pregnancies. Extra planning is needed because weight gain and balance changes can raise fall risk, and some medicines used for pain or spasticity are unsafe in pregnancy. Genetic counselling can explain inheritance patterns, and obstetricians can coordinate care with neurologists.

11. Should my family members be tested?
This depends on the specific gene, family plans, and personal preferences. Some relatives may wish to know if they carry the gene before having children. Genetic counsellors help families understand the pros and cons of testing and make informed decisions. NCBI+1

12. Can diet change the course of the disease?
Diet cannot remove the genetic cause, but a healthy diet helps maintain weight, muscle, and bone health, which all support mobility. Correcting deficiencies in vitamins like B12 or D, if present, is important and can improve general nerve and muscle function.

13. Are alternative or herbal treatments useful?
Some people try herbal remedies or alternative therapies. Evidence for most is weak or absent, and some may interact with prescription medicines or cause harm. Always discuss any alternative treatment with your doctor and avoid anything that claims to “cure” CMT or HMSN.

14. How often should I see my healthcare team?
Many people benefit from at least yearly visits with a neurologist and regular reviews with physical and occupational therapists. More frequent visits may be needed if symptoms change, if you are adjusting medicines, or after surgery. ScienceDirect+2PMC+2

15. What is the long-term outlook (prognosis)?
HMSN type 5 usually progresses slowly over many years. Most people have a normal life expectancy but may need increasing support with mobility, self-care, or work as they age. With early rehabilitation, careful symptom control, and good self-care, many people lead active, meaningful lives, study, work, and participate fully in family and community activities.
