Abstract
This retrospective study examined the common notion that neuroleptic-induced dystonia is less frequent in elderly patients. The hospital records of 45 young patients and 45 elderly patients were reviewed. Thirty-one percent of the young patients developed a dystonia, compared to 2% of the elderly patients. This significant difference did not appear to be the result of types of neuroleptics used, dose or concomitant administration of anticholinergic drugs.
