title: Neuroleptic-induced dystonia: incidence and risk factors.
abstract: Retrospective evaluation of patients admitted consecutively to the psychiatric units of two general hospitals in Florence, to evaluate the rate and risk factors of neuroleptic-induced dystonia (NDA). One hundred and fifty-nine patients out of 2354 reviewed charts were included. The incidence of NDA was 15.7%. Multivariate analyses revealed that both age and neuroleptization speed (NS)-a new variable-were related to the occurrence of dystonia.
