Many neurologic conditions present with motor dysfunction. It is often helpful to distinguish these movement abnormalities in order to properly recognize and manage the disorder.
Chorea >>> Sudden, ballistic movements.
Athetosis >>> Writhing, repetitive movements.
Fasiculations >>> Fine twitching of individual muscle bundles, most easily noted on the tongue.
Dystonia >>> Sudden, tonic contractions of muscles of the tongue, neck (torticollis), back (opisthotonos), mouth, or eyes (oculogyric crisis).
