Akathisia
Pronunciation: ah-kah-THEE-zee-ah
A movement disorder characterized by feelings of inner restlessness and an irresistible urge to move, commonly caused by antipsychotic medications.
Full Definition
Akathisia is an extrapyramidal side effect that can occur with antipsychotic medications, particularly first-generation agents, though it can also occur with second-generation antipsychotics and other medications. Patients experience subjective feelings of restlessness, anxiety, and an inability to sit still, often accompanied by pacing, rocking, or repetitive movements. Unlike tardive dyskinesia, akathisia typically occurs early in treatment and is often reversible with medication adjustment. The condition can be confused with anxiety or agitation, making accurate assessment crucial for appropriate intervention. Documentation should clearly distinguish akathisia from psychiatric symptoms to guide proper treatment modifications.
Usage
Usage note: Distinguish clearly from anxiety or agitation in clinical documentation. Note relationship to medication timing.
