Charcot–Marie–Tooth Disease (CMT) is a group of conditions that affect the peripheral nerves. It is usually inherited and can be associated with a range of symptoms, including muscle weakness, loss of sensation, and foot deformities. In some cases, CMT may be accompanied by palmoplantar keratoderma (thickening of the skin on the palms and soles) and nail dystrophy (changes in the nails). This combination of symptoms is known as CMT with palmoplantar keratoderma and nail dystrophy (CMT-PPKND). This condition can be difficult to diagnose since its symptoms are similar to those of other diseases. Charcot–Marie–Tooth Disease (CMT) is a group of inherited disorders that affect the peripheral nervous system. It is one of the most common inherited neurological disorders, affecting about 1 in 2,500 people worldwide. CMT is named after three doctors: Jean-Martin Charcot and Pierre Marie from France, and Howard Henry Tooth from England, who first described the disease in 1886.

CMT affects the peripheral nerves, which are responsible for carrying messages between the brain and muscles throughout the body. These messages allow us to move our muscles and perform everyday activities such as walking or running. In people with CMT, these peripheral nerves become damaged, resulting in muscle weakness and wasting in the feet, legs, hands, and forearms. Other symptoms may include numbness or tingling in the affected areas. Over time, some people with CMT may experience difficulty walking or balancing due to muscle weakness.

Causes of Charcot–Marie–Tooth Disease

Charcot–Marie–Tooth disease (CMT) is a group of inherited disorders that affect the peripheral nerves. These disorders are caused by genetic mutations that lead to destruction of the myelin sheath that surrounds and protects nerve fibers. There are several causes of CMT, including:

  • Genetic Mutations: CMT is caused by mutations in the genes responsible for making proteins that are essential for the proper functioning of peripheral nerves. Mutations in any one of these genes can lead to CMT.
  • Inheritance: CMT can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. Autosomal dominant inheritance is when a mutation in one copy of a gene is enough to cause the disorder. Autosomal recessive inheritance is when two copies of a gene must have mutations for the disorder to be expressed. X-linked inheritance occurs when the mutation is located on the X chromosome.
  • Environmental Factors: Exposure to certain environmental factors such as toxins, drugs, or radiation may increase an individual’s risk for developing CMT.

CMT can also be caused by acquired conditions such as diabetes, alcoholism, or viral infections. In some cases, no cause can be identified and CMT may be idiopathic. Treatment for CMT depends on its severity and type and typically involves physical therapy and occupational therapy as well as medications to reduce pain and manage symptoms.

CMT symptoms vary depending on severity but typically include muscle weakness and atrophy in the foot and lower leg muscles; decreased sensation in legs and feet; changes in foot structure including hammertoes, high arches, or flat feet; impaired balance; and pain in feet or legs. Additional symptoms may include numbness or tingling sensations in hands or feet; abnormal gait; difficulty with coordination; muscle twitching; slow reflexes; fatigue; foot deformity; scoliosis; curvature of spine.

Charcot–Marie–Tooth Disease Symptoms

Charcot–Marie–Tooth (CMT) disease is a neurological disorder that affects the peripheral nerves. Symptoms of this disorder vary greatly depending on the type of CMT and can range from mild to severe. Common symptoms include:

• Muscle weakness and atrophy in the feet, legs, hands, and forearms
• Loss of feeling or reduced sensation in the feet, legs, hands, and forearms
• High arches in the feet
• Hammertoes
• Curled toes
• Pes cavus (high foot arch)
• Abnormal gait or foot drop due to muscle weakness in the legs
• Balance problems or clumsiness due to poor coordination
• Difficulty running or walking long distances due to muscle fatigue
• Painful cramping of muscles in the arms or legs after exercise or when exposed to cold temperatures.

In some cases, people with CMT may also experience hearing loss, tinnitus (ringing in the ears), vision problems, and/or difficulty breathing. Symptoms typically become worse over time as nerve damage progresses. In severe cases, it can lead to paralysis of the lower limbs. Treatment for CMT varies depending on the type and severity of symptoms but may include physical therapy, medications for pain relief, orthopedic braces or splints, and surgical procedures to correct any deformities.

Palmoplantar Keratoderma in Charcot–Marie–Tooth Disease

Palmoplantar keratoderma (PPK) is a condition that affects the skin on the palms of the hands and soles of the feet, causing thickening and roughness. It is most commonly associated with Charcot-Marie-Tooth disease (CMT), an inherited neurological disorder that affects movement and sensation. This article will discuss the characteristics, causes, diagnosis, and treatment of PPK in CMT.


PPK usually appears as diffuse areas of thickened skin on the palms of the hands and soles of the feet. The skin may be dry, scaly, or pitted. In some cases, it can become painful or inflamed. The condition can also cause muscle weakness in the hands or feet due to nerve damage caused by CMT.


The exact cause of PPK in CMT is not known, but it is believed to be related to a mutation in certain genes involved in nerve cell function. This mutation disrupts normal nerve signals and can lead to changes in the structure and function of nerves throughout the body, including those responsible for controlling sensation and movement in the hands and feet.


PPK is usually diagnosed based on a physical examination and a review of medical history. A doctor may also order blood tests or genetic testing to confirm a diagnosis of CMT. In some cases, imaging tests such as X-rays or MRI scans may be used to rule out other causes for PPK symptoms.


Treatment for PPK depends on its severity and underlying cause. For mild cases, treatment typically involves using emollient creams or lotions to soothe dryness or discomfort. Severe cases may require more aggressive treatments such as topical corticosteroids or systemic immunosuppressants to reduce inflammation and improve skin texture. Physical therapy may also be recommended to help improve muscle strength affected by CMT-related nerve damage.


Nail Dystrophy in Charcot–Marie–Tooth Disease

Nail dystrophy is one of the characteristic signs of Charcot–Marie–Tooth disease, a rare inherited neurological disorder. Nail dystrophy affects both the toenails and fingernails and is caused by damage to the peripheral nerves. Symptoms range from changes in the shape and texture of the nails, to ridges, deformities, discoloration, and brittleness.

In some cases of nail dystrophy caused by Charcot–Marie–Tooth disease, discoloration may occur in patches or throughout an entire nail plate. The nails may become distorted with ridges and grooves that run in different directions. Over time, they can become abnormally thick or thin with a brittle texture that can easily break or chip away.

Other symptoms associated with nail dystrophy include ridges or bumps on the nails, separation of the nail from the nail bed, and discoloration of the underlying skin. In some cases, it can cause pain or discomfort when pressure is placed on the affected nail.

Treatment for nail dystrophy due to Charcot–Marie–Tooth disease consists mainly of supportive measures such as wearing shoes that fit properly and avoiding activities that put excessive pressure on nails. Applying moisturizers to keep cuticles hydrated may also be beneficial. For more severe cases, medication or surgery may be necessary to correct any deformities and restore normal function.

It is important to remember that while nail dystrophy is a common symptom of Charcot-Marie-Tooth disease, it can also be caused by other conditions such as fungal infections or psoriasis. Therefore, it is important to seek medical attention if you notice any changes in your nails so that an accurate diagnosis can be made and appropriate treatment provided.

Diagnosing Charcot–Marie–Tooth Disease

Charcot-Marie-Tooth (CMT) disease is a genetic disorder of the peripheral nerves that can cause muscle weakness, loss of sensation, and deformities in the feet and lower legs. Diagnosing CMT involves a combination of physical exam, family medical history, and laboratory tests.

• Physical Exam: A doctor will perform a physical exam to look for signs of muscle weakness and deformities in the feet, ankles, or lower legs. The doctor may also check for impaired sensation in the hands or feet.

• Family Medical History: A doctor may ask about a person’s family members’ medical history to determine if they have any conditions that can be associated with CMT.

• Laboratory Tests: CMT can be diagnosed using laboratory tests such as nerve conduction studies, electromyography (EMG), genetic testing, and imaging tests. Nerve conduction studies measure electrical signals sent along nerves to detect abnormalities in nerve function. EMG measures electrical activity in muscles to detect muscle damage or abnormalities. Genetic testing looks for mutations or changes in genes associated with CMT. Imaging tests such as magnetic resonance imaging (MRI) may be used to detect any physical changes in the brain or spinal cord caused by CMT.

Once all of these tests are completed, a diagnosis of CMT can be made based on the results. Treatment options include physical therapy, orthopedic devices such as braces or splints, medications to reduce pain and inflammation, and surgery to correct deformities in the feet or lower legs.

Overview of Charcot–Marie–Tooth Disease

Charcot–Marie–Tooth disease (CMT) is a hereditary, neurological disorder that affects the peripheral nerves. It is characterized by progressive muscle weakness and atrophy in the feet, lower legs, hands, and forearms. CMT can vary in severity and may also affect hearing, balance, and vision. Symptoms typically begin in childhood or adolescence; however, they may not be noticeable until adulthood.

There is no cure for CMT; however, there are treatments available to help manage symptoms and improve quality of life. Treatment may include physical therapy, occupational therapy, braces and splints, medications for pain relief or muscle relaxation, surgery for tendon transfers or joint fusion to improve stability and mobility.

Treatment Options

• Physical Therapy: Physical therapy can help reduce pain and improve strength and flexibility in affected areas. Stretching exercises can be used to stretch muscles that have become tight due to disuse or atrophy. Strengthening exercises can also be used to help build muscle mass in weakened muscles.

• Occupational Therapy: Occupational therapy can help individuals with CMT improve their ability to perform daily activities by teaching them how to use adaptive equipment or find alternative methods of completing tasks.

• Braces/Splints: Orthopedic braces may be used to provide additional support for weak joints or muscles and prevent deformities from developing. Splints can also be used at night to keep joints in correct positions while sleeping.

• Medications: Pain medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce pain associated with CMT. Muscle relaxants such as diazepam (Valium) may also be prescribed to help alleviate muscle spasms or cramps.

• Surgery: In some cases, tendon transfers or joint fusion surgery may be recommended if conservative treatment fails to improve symptoms. Tendon transfers involve transferring a healthy tendon from one area of the body to another area where it is needed for support or strength.

Overall, treatment of CMT focuses on symptom management rather than a cure; however, with proper treatment it is possible for individuals with CMT to lead productive lives despite the effects of the disease on their physical abilities.

Charcot-Marie-Tooth Disease with Palmoplantar Keratoderma and Nail Dystrophy

Charcot-Marie-Tooth (CMT) disease is a hereditary peripheral nerve disorder that affects movement and sensation in the arms and legs. It is a genetic disorder that can cause weakness in the lower legs, feet, and hands. Symptoms of CMT vary depending on the type of CMT, but may include: muscle wasting, difficulty walking, numbness or tingling in the hands and feet, pain in the feet or ankles, high foot arches, hammertoes or clawed toes, and changes in gait. CMT with palmoplantar keratoderma (PPK) and nail dystrophy is a rare type of CMT that is associated with an autosomal recessive form of PPK.

PPK is a skin condition characterized by thickening of the palms and soles of the feet along with nail dystrophy. In some cases, it may be accompanied by severe pain or itching. The nails may become thicker or brittle due to lack of circulation to the area. The prognosis for individuals with this type of CMT depends on their individual symptoms as well as their family’s medical history.

Treatment for CMT with PPK and nail dystrophy includes physical therapy to improve motor skills, occupational therapy to improve hand dexterity and strength, surgery to correct deformities such as hammertoes or clawed toes, orthopedic care for deformities such as high foot arches, medications to relieve pain caused by nerve damage such as gabapentin or tricyclic antidepressants such as amitriptyline; use of orthotics/splints for better support; supportive footwear; splinting; electrical stimulation; transcutaneous electrical nerve stimulation (TENS); deep tissue massage; vibration therapy; laser therapy; ultrasound therapy; dietary modifications; natural treatments such as yoga/tai-chi/meditation/acupuncture etc.; supportive counseling etc..

Prognosis for those affected by this condition depends on how well individuals respond to treatment. In some cases, symptoms may improve over time if they are managed properly and lifestyle modifications are made. However, it is important to note that there is no cure for this condition at this time.
