Neurology. Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain's cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE). The symptoms can be acute (short-term) or chronic (long-term).
In anatomy, the extrapyramidal system is a part of the motor system network causing involuntary actions. [ 1 ] The system is called extrapyramidal to distinguish it from the tracts of the motor cortex that reach their targets by traveling through the pyramids of the medulla. The pyramidal tracts (corticospinal tract and corticobulbar tracts ...
The terminology can still be imprecise. The definition of "atypicality" was based upon the absence of extrapyramidal side effects, but there is now a clear understanding that atypical antipsychotics can still induce these effects (though to a lesser degree than typical antipsychotics). [133]
Akathisia (IPA: /æ.kə.ˈθɪ.si.ə/) is a movement disorder [5] characterized by a subjective feeling of inner restlessness accompanied by mental distress and/or an inability to sit still. [6][4] Usually, the legs are most prominently affected. [2] Those affected may fidget, rock back and forth, or pace, [7] while some may just have an uneasy ...
Risperidone seems to produce somewhat more extrapyramidal side effects and clearly more prolactin increase than other atypical antipsychotics. It may also differ from other compounds in the occurrence of other adverse effects such as weight gain, metabolic problems, cardiac effects, sedation, and seizures.
Extrapyramidal side effects, although potentially serious, are infrequent to rare from olanzapine, [44] but may include tremors and muscle rigidity. Aripiprazole, asenapine, clozapine, quetiapine and olanzapine, in comparison to other antipsychotic drugs, are less frequently associated with hyperprolactinaemia. Although these drugs can cause ...
Rabbit syndrome is a rare [1] form of extrapyramidal side effect of antipsychotic drugs in which perioral tremors occur at a rate of approximately 5 Hz. Rabbit syndrome is characterized by involuntary, fine, rhythmic motions of the mouth along a vertical plane, without involvement of the tongue, [2] [3] and resembling the chewing movements of a rabbit.

In Wikidata. A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and as such they have found use in treating schizophrenia, bipolar disorder, and stimulant psychosis. [ 1 ]
