Charcot Marie Tooth disease

CMT, hereditary motor and sensory neuropathy (HMSN), peroneal muscular atrophy (PMA)

What is Charcot Marie Tooth disease?

Charcot-Marie-Tooth disease is a group of inherited conditions that damage the peripheral nerves.

What causes Charcot Marie Tooth disease?

CMT is caused by an inherited fault in one of the many genes responsible for the development of the peripheral nerves. This fault means the nerves become damaged over time.

A child with CMT may have inherited the genetic fault responsible for the condition from one or both of their parents.

There’s no single faulty gene that causes CMT. There are many types of CMT that are caused by different genetic faults and these can be inherited in several different ways.

The chances of passing CMT to your child depend on the specific genetic faults you and your partner carry.

What are the symptoms of Charcot Marie Tooth disease?

People with CMT may have:

  • Muscle weakness in their feet, ankles, legs and hands
  • An awkward way of walking (gait)
  • Highly arched or very flat feet
  • Numbness in the feet, arms and hands

CMT is a progressive condition. This means the symptoms get slowly worse, making everyday tasks increasingly difficult.

Caring for someone with Charcot Marie Tooth disease

We support carers, friends and family too

Are you a carer for or relative of someone with Charcot Marie Tooth disease? It’s just as important for you to look after your own physical and mental wellbeing too.

The Brain Charity provides free support for carers, friends and family of people with any form of neurological condition, including Charcot Marie Tooth disease, from anywhere in the UK.

We also run an additional carers advocacy service for all carers in Liverpool, regardless of which type of condition the person they care for has.

You don’t need to be a formal or registered carer

We can help you even if you don’t view yourself as a formal carer or claim Carer’s Allowance. Find out some of the ways we support carers below.
