Multifocal motor neuropathy is a progressive muscle disorder characterized by muscle weakness in the hands, with differences
from one side of the body to the other in the specific muscles involved. It affects men much more than women. Symptoms also
include muscle wasting, cramping, and involuntary contractions or twitching of the leg muscles. The disorder is sometimes
mistaken for amyotrophic laterial sclerosis (ALS, or Lou Gehrig's disease) but unlike ALS, it is treatable. An early and accurate
diagnosis allows patients to recover quickly.
Is there any treatment?
Treatment for multifocal motor neuropathy varies. Some individuals experience only mild, modest symptoms and require no treatment.
For others, treatment generally consists of intravenous immunoglobulin (IVIg) or immunosuppressive therapy with cyclophosphamide.
What is the prognosis?
Improvement in muscle strength usually begins within 3 to 6 weeks after treatment is started. Most patients who receive treatment
early experience little, if any, disability. However, there is evidence of slow progression over many years.
What research is being done?
The NINDS supports a broad range of research on neuromuscular disorders with the goal of finding ways to prevent, treat, and,
ultimately, cure them.
