chorea
Pronunciation: ko-REE-ah
Involuntary, irregular, flowing movements that appear dance-like and unpredictable in timing and location.
Full Definition
Chorea describes involuntary hyperkinetic movements characterized by irregular, flowing, and unpredictable motions that can affect any part of the body. The movements appear dance-like and are typically non-repetitive, distinguishing them from other movement disorders such as dystonia or tremor. Chorea can be seen in Huntington's disease, rheumatic fever (Sydenham's chorea), drug-induced conditions, and various other neurological disorders. Clinical documentation should specify the distribution of choreiform movements and any associated symptoms. The term derives from the Greek word for dance and requires careful description in medical records to distinguish it from other involuntary movements.
Usage
Usage note: Often confused with dystonia (sustained abnormal postures) or athetosis (slow writhing movements); chorea is specifically irregular and flowing.
