| akathisia, drug-induced | Motor restlessness with sensations of quivering and an urge to move about constantly resulting from the use of certain drugs, such as neuroleptic drugs, which affect the extrapyramidal region of the brain. This differs from dyskinesia, drug-induced in that long-term antipsychotic drug exposure is significantly correlated with the increased prevalence of akathisia while there is no such correlation with dyskinesia. The primary observable distinction between tardive akathisia and dyskinesia appears to be in the repetitive, stereotypy of the dyskinesic movements (lip smacking, for example), while akathisia is associated with anxiety, restlessness, and agitation (psychomotor agitation).
