title: Behavioral toxicity of antipsychotic drugs.
abstract: Extrapyramidal symptoms cause much misery, often go undiagnosed, and can interfere with treatment and rehabilitation. Akinesia is a behavioral state of diminished motoric and psychic spontaneity that is difficult to distinguish from the negative symptoms of schizophrenia. The most useful clinical correlates of akinesia are a subjective sense of sedation and excessive sleeping. Akinesia interferes with social adjustment and may manifest as "postpsychotic depression." The subjective restlessness of akathisia is usually accompanied by telltale foot movements: rocking from foot to foot while standing or walking on the spot. Akathisia is strongly associated with depression and dysphoric responses to neuroleptics and has even been linked to suicidal and homicidal behavior in extreme cases.
