May 12, 2023 · Multifocal motor neuropathy (MMN) is a disease that affects your body's motor nerves. Those are the nerves that control your muscles. The condition makes it hard for them to send the...

Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken. The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.

What is MMN? MMN (Multifocal Motor Neuropathy) is a rare disorder in which focal areas of multiple motor nerves are attacked by one’s own immune system. Typically, MMN is slowly progressive, resulting in asymmetrical weakness of a patient’s limbs.

Multifocal motor neuropathy (MMN) causes damage to the nerves in the arms and legs. Nerve damage begins in adulthood and slowly gets worse over time. One side of the body may be more affected than the other.

Jul 16, 2023 · Multifocal motor neuropathy (MMN), also called multifocal motor neuropathy with conduction block (MMNCB), is a rare, acquired, motor neuropathy characterized by progressive asymmetric weakness without sensory problems. It typically involves upper …

Jan 8, 2024 · Multifocal motor neuropathy (MMN) is a rare immune-mediated motor neuropathy characterized by asymmetric weakness that preferentially affects distal upper limb muscles. The clinical features of MMN may be difficult to differentiate from motor neuron disease.

Mar 12, 2025 · Multifocal Motor Neuropathy (MMN) is a rare condition in which multiple motor nerves are attacked by one’s immune system. This causes weakness without loss of sensation. The disorder affects less than one person per 100,000 people.

Multifocal motor neuropathy (MMN) is an uncommon, purely motor neuropathy associated with asymmetric deficits with predilection for upper limb involvement. Even in the early descriptions of MMN, the associations of anti-GM1 antibodies and robust ...

Multifocal motor neuropathy, or MMN, is a rare disorder in which multiple motor nerves are attacked by one's own immune system, causing muscle weakness that can worsen over time. Learn more about MMN and why it is sometimes misdiagnosed.
