Patients with multifocal motor neuropathy (MMN) experience decreased strength and mobility over time. We understand patients dealing with muscle and nerve issues need a supportive environment to thrive in the face of MMN. We are proud to play a part in creating this environment throughout treatment. Living with a neuropathy can be a challenge, which is why we’re here to listen, investigate funding options, answer questions and guide patients through all their treatments.

Multifocal Motor Neuropathy

One of the first steps after a multifocal motor neuropathy (MMN) diagnosis is understanding the condition. The information on this site and linked sites is not meant to replace your physician’s advice, medical care or a diagnosis. If you have questions about your disease, please ask your prescriber.


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.
