Abstract 

The authors investigated the subjective cognitive dysfunction associated with drug-induced parkinsonism (DIP) among 58 stabilized schizophrenic outpatients. Subjective cognitive dysfunction was comprehensively assessed using the Frankfurt Complaint Questionnaire (FCQ). Multivariate analysis revealed that the DIP group scored significantly higher on the total FCQ score than the non-DIP group. In phenomenological subscale scores, the DIP group had significantly higher scores on “deterioration of discrimination”, “psychomotor disorder”, and “perceptual disorder” than the non-DIP group. These results suggest that DIP is significantly associated with subjective cognitive-perceptual dysfunction, reflecting the complex nature of DIP that includes motor and cognitive aspects.
