Is Motor Neuropathy hereditary?
This condition is inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder.
Can MMN go into remission?
It is rare that MMN will go into remission. In some cases, MMN will initially respond to treatment (see “Therapy” section) but then stop responding to treatment and remain stable.
What is the treatment for MMN?
Multifocal motor neuropathy (MMN) is considered treatable with intravenous immune globulin (IVIG). Early treatment shortly after symptoms begin is recommended. Most people have a fairly rapid improvement in weakness with IVIG, but the improvement generally does not last beyond a few months.

Can MMN be cured?
What is Mama disease?
Multifocal acquired motor axonopathy (MAMA) is an extremely rare neuromuscular disease that is often misdiagnosed as ALS (amyotrophic lateral sclerosis) due to similarities in the symptoms that initially occur in affected individuals.
What are symptoms of Multifocal motor neuropathy (MMN)?
[1] [2] [3] [4] Signs and symptoms of multifocal motor neuropathy (MMN) may include weakness; cramping; involuntary contractions or twitching; wrist drop or foot drop; and wasting (atrophy) of affected muscles. [5] [6] Atrophy occurs late in the course of the condition. [1]
What is multiple motor neuropathy?
Overview. Your peripheral nervous system is made up of the nerves outside your central nervous system.
What is multifocal acquired motor axonopathy?
Multifocal acquired motor axonopathy (MAMA) is an extremely rare neuromuscular disease that is often misdiagnosed as ALS (amyotrophic lateral sclerosis) due to similarities in the symptoms that initially occur in affected individuals. MAMA typically begins as weakness in the hands and arms, although it can also sometimes develop first in the feet or legs.
