Loss of balance and frequent falls

Muscle cramps and fasciculations
Fasciculations are small, involuntary muscle contractions visible under the skin (often in the arms or calves).
They can be frequent and bothersome.

Some patients notice a weaker voice, slurred speech, or difficulty articulating clearly.
This is a typical sign when the affected area involves the muscles of the face or throat.
