Summary Summary

Charcot-Marie-Tooth disease is a group of disorders that affect the peripheral nerves, the nerves running from outside the brain and spine.^[1] Defects in many different genes cause different forms of this disease. Common symptoms may include foot drop, foot deformity, loss of lower leg muscle, numbness in the foot or leg, “slapping" gait (feet hit the floor hard when walking), and weakness of the hips, legs, or feet.^[1] There is currently no cure for Charcot-Marie-Tooth disease, but physical therapy, occupational therapy, braces and other orthopedic devices, pain medication, and orthopedic surgery can help manage and improve symptoms.^[2]

There are over 40 types of Charcot-Marie-Tooth disease. You can search for more information on a particular type of Charcot-Marie-Tooth disease from the GARD Home page. Enter the name of the condition in the GARD search box, and then select the type from the drop down menu.

Find a Specialist Find a Specialist

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.
