Polyminimyoclonus refers to involuntary, jerky, small amplitude, tremor-like movements, most commonly seen in hands. The commonest cause is degenerative anterior horn cell disease, commonly known as motor neuron disease or amyotrophic lateral sclerosis. These tremor-like movements (polyminimyoclonus) correspond to fasciculations in forearm muscles.
Amyotrophic lateral sclerosis (ALS) is a degenerative neurological disease affecting only the motor system. It is also referred to as motor neuron disease (MND) and is characterized by muscle wasting, weakness and fasciculations. Fasciculations refer to involuntary contractions/twitching of affected muscles. Affected muscles are wasted (thin) and weak. In this video, you can see fasciculationsContinue reading “FASCICULATIONS”
