Abstract

Background: Although schizophrenia affects all age groups, late or very-late-onset schizophrenia-like psychosis has not been well studied and various treatment issues remain unresolved. The objective of the present study was to evaluate the efficacy and safety of amisulpride monotherapy in a diagnostically homogeneous group of elderly patients without cognitive impairment suffering from very-late-onset schizophrenia. Methods: Twenty-six patients of mean age 76.2±5.8 years, fulfilling both the recent consensus criteria for very late-onset schizophrenia-like psychosis and the DSM-IV-TR criteria for schizophrenia, were assessed by the Brief Psychiatric Rating Scale, the Clinical Global Impression Scale and the Positive and Negative Syndrome Scale at baseline and five weeks following amisulpride (50-200 mg/day) administration; also, the presence of abnormal movements was evaluated with the Simpson-Angus Scale, the Barnes Akathisia Scale, and the Abnormal Involuntary Movement Scale. Results: A highly significant (p<0.001) improvement on all measures of psychotic symptomatology was observed in all patients. Amisulpride was very well tolerated by the patients and no clinically significant adverse effects were observed. Scores on all abnormal movement scales did not differ significantly prior to and after amisulpride treatment. Conclusion: Preliminary results indicate that amisulpride appears to be an efficacious and safe atypical antipsychotic for the treatment of very-late-onset schizophrenia-like psychosis.
