extrapyramidal symptoms
Also written as: EPS
Movement-related side effects of antipsychotic medications affecting the extrapyramidal motor system.
Full Definition
Extrapyramidal symptoms (EPS) are a group of movement disorders that can occur as side effects of antipsychotic medications and other dopamine-blocking drugs. These symptoms result from disruption of the extrapyramidal motor system in the brain. EPS includes acute dystonia (muscle spasms), parkinsonism (tremor, rigidity, bradykinesia), akathisia (restlessness), and tardive dyskinesia (delayed-onset involuntary movements). Early identification and management of EPS is crucial for treatment adherence and patient quality of life.
Usage
Usage note: Use EPS abbreviation only after spelling out; distinguish from 'neurological side effects.'
