Dyskinesia

Dyskinesia is a movement disorder which consists of effects including diminished voluntary movements^[1] and the presence of involuntary movements, similar to tics or chorea. Dyskinesia is a symptom of several medical disorders and is distinguished by the underlying cause.

Acute

• Acute dystonia

Chronic/tardive

• When a dyskinesia presents after treatment with an antipsychotic drug such as haloperidol (Haldol), it is known as tardive dyskinesia, and is commonly seen in the face and mouth in the form of 'tongue rolling'.

• Rabbit syndrome

• Dyskinesia observed in a patient with Parkinson's disease (PD) is labeled as Levodopa-induced dyskinesia (LID), and is more commonly a jerky, dance-like movement of the arms and/or head, which usually presents after several years of treatment with L-DOPA (Levodopa).

Non-motor

Two other types, primary ciliary dyskinesia, and biliary dyskinesia, are caused by specific kinds of ineffective movement of the body, and are not movement disorders.
