akathisia
Pronunciation: ak-uh-THIZ-ee-uh
A medication-induced movement disorder characterized by subjective restlessness and inability to remain still.
Full Definition
Akathisia is a neuropsychiatric syndrome most commonly caused by antipsychotic medications, characterized by an inner sense of restlessness and compulsive need to move. Patients may pace, rock, or shift weight from foot to foot. The condition can be acute (occurring within days of starting medication) or tardive (developing after months or years of treatment). Recognition is crucial as akathisia can be mistaken for anxiety or agitation and may contribute to treatment non-compliance.
Usage
Usage note: Often misspelled as 'acathisia'. Distinguish from psychological restlessness by noting the involuntary motor component.
