What are the signs and symptoms of multifocal motor neuropathy?

Signs and symptoms of multifocal motor neuropathy (MMN) may include weakness; cramping; involuntary contractions or twitching; and wasting (atrophy) of affected muscles.[1] Atrophy occurs late in the course of the condition.[2] Muscles of the hands and lower arms are most commonly affected, but muscles of the lower limbs may also be involved. The symptoms are often asymmetrical, meaning that they differ on the right and left side of the body.[3][1]
