The leading cause of extrapyramidal syndrome is psychiatric medication. Antipsychotic drugs and some drugs used to treat depression commonly cause extrapyramidal symptoms. Patients who take dopamine blockers can also develop this condition.
These newer medications differ from their conventional counterparts, primarily based on their reduced risk of extrapyramidal symptoms (EPS). EPS can be categorised as acute (dystonia, akathisia and parkinsonism) and tardive (tardive dyskinesia and tardive dystonia) syndromes.
