COVID-19: Guidelines on Charcot Marie Tooth disease from the Neuromuscular Service, NHNN

COVID-19: Guidelines on Charcot Marie Tooth disease from the Neuromuscular Service, National Hospital for Neurology and Neurosurgery (NHNN), Queen Square, London.

Prepared by Professor Mary M Reilly and Dr. Matilde Laura, NHNN, 23rd April 2020

The following are general guidelines and are adapted from NHS website and Public Health UK.

Charcot Marie Tooth disease (CMT) is a condition that affects sensory and/or motor nerves. For most patients with CMT, your risk is the same as the general public. HOWEVER- there are patients with CMT who have additional problems due to their CMT (e.g. some patients, including some with kyphoscoliosis, neuromuscular chest problems, diaphragm weakness or vocal cord paralysis may require help with their breathing such as with NIV or CPAP at night). If you are on CPAP or NIV please contact your Respiratory Centre for information. Patients with CMT may also have other unrelated medical problems that put them at risk.

If you fall frequently or have balance problems please be MINDFUL. We need to bear in mind that A&E and GP services will be under much more pressure than usual. This will mean delays in all usual hospital services.

If you are on regular medications contact your local GP services on how to get your repeat prescriptions and their contingency plan in the event of decreased services.

Please visit the Centre for Neuromuscular Diseases ( and the Association of British Neurologists (ABN) websites for more information: The ABN website has a patient section and is updated regularly.
