Akathisia is a common
extrapyramidal side-effect of
antipsychotic (aka
neuroleptic[?])
drugs. It usually manifests as pacing and a total inability to sit still. If forced to sit still the person experiences extream anxiety and agitation. In bad cases the anxiety and agitation may get worse even while the person is moving. Akathisia usually responds well to drugs commonly used to control
extrapyramidal side-effects.
