tardive akathisia
Late-onset movement disorder characterized by persistent restlessness and inability to remain still, caused by long-term antipsychotic use.
Full Definition
Tardive akathisia is a form of tardive syndrome that develops after chronic exposure to dopamine receptor blocking agents, particularly antipsychotics. Unlike acute akathisia, which occurs early in treatment, tardive akathisia emerges after months or years of medication use and may persist even after discontinuation. Patients experience subjective restlessness, anxiety, and an irresistible urge to move, often accompanied by repetitive movements such as rocking, pacing, or fidgeting. This condition can be particularly distressing and may be mistaken for anxiety or agitation, leading to inappropriate treatment adjustments.
Usage
Usage note: Always specify 'tardive' to distinguish from acute akathisia.
