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 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.
