What is motor neuropathy (MMN)?

ANSWER

Multifocal motor neuropathy (MMN) is a disease that affects the nerves that control your muscles. It interferes with the electrical signals that move your body, which makes your hands and arms feel weak. They’ll also twitch and cramp.

Treatments can strengthen your muscles. MMN can get worse slowly, and after a while, you may have a hard time dressing yourself or doing other tasks. But for many people, symptoms may be so mild that they don't need treatment at all. Most people are diagnosed with MMN in their 40s and 50s, but it can happen to adults of any age.
