The abnormal movement characterized by spasmodic and involuntary movements of the face and limbs is known as chorea. Chorea is typically described as having a rapid, irregular, and unpredictable quality, with movements that often appear to be fluid and dance-like. This can affect various muscle groups, leading to difficulties with intentional movements and coordination.

Chorea results from a dysfunction in the basal ganglia, which are part of the brain that helps regulate movement. Conditions such as Huntington's disease, Sydenham's chorea, and certain types of drug-induced movement disorders can lead to chorea, showcasing the way these involuntary movements manifest in a person's motor function.

In contrast, athetosis refers to slow, writhing movements typically seen in the hands and feet, while dystonia involves sustained muscle contractions causing twisting or repetitive movements. Ballism consists of more forceful, flinging movements, typically occurring in the proximal muscles. Understanding these distinctions helps clarify the specific nature of chorea compared to other movement disorders.
