Learn More About Multifocal Motor Neuropathy

One of the first steps after a multifocal motor neuropathy (MMN) diagnosis is understanding the condition. Diplomat is here to help.

But remember: The information here — and on linked sites — is not meant to replace advice, care, or a diagnosis from your physician. If you have questions about your condition, please ask your provider.


Multifocal motor neuropathy, sometimes misdiagnosed as amyotrophic lateral sclerosis (ALS), involves the patient’s muscles, primarily in the arms and legs, becoming weaker. It is thought to be caused by an immune attack on nerve fibers in the extremities. Over time, this affects the patient’s mobility. Patients might experience cramping, involuntary muscle contractions or muscle wasting. While it does share symptoms with ALS, it does not affect the brain or spinal cord.

Men are three times more likely than women to be diagnosed with MMN, and patients are typically diagnosed before age 45. In contrast to ALS, the disease is not life-threatening and can be slowed considerably with treatment. With the right care team, it is possible for patients to live active and full lives.
