EPS
Also written as: EPS — Extrapyramidal Symptoms
Extrapyramidal symptoms, movement disorders caused by antipsychotic medications affecting the basal ganglia.
Full Definition
Extrapyramidal symptoms (EPS) refer to a group of movement disorders that can occur as side effects of antipsychotic medications. These symptoms result from the blockade of dopamine receptors in the basal ganglia and include acute dystonia, parkinsonism, akathisia, and tardive dyskinesia. EPS are more commonly associated with first-generation (typical) antipsychotics but can also occur with second-generation (atypical) medications. Prompt recognition and management of EPS are crucial for patient safety and treatment compliance.
