extrapyramidal symptoms
Pronunciation: EK-strah-pih-RAM-ih-dal
Movement disorders caused by dysfunction of the extrapyramidal motor system, often due to antipsychotic medications.
Full Definition
Extrapyramidal symptoms (EPS) are a group of movement disorders that result from disruption of the extrapyramidal motor system, primarily involving dopamine pathways in the brain. In geriatric psychiatry, these symptoms are most commonly encountered as side effects of antipsychotic medications used to treat behavioral symptoms of dementia or late-life psychosis. EPS includes dystonia, parkinsonism, akathisia, and tardive dyskinesia. Elderly patients are at higher risk for developing these symptoms due to age-related changes in brain chemistry and increased sensitivity to medications. Monitoring and management of EPS is crucial in geriatric psychiatric care to maintain quality of life and medication adherence.
Usage
