Abstract

OBJECTIVES:

To assess prevalence and pattern of movement disorders among patients taking antipsychotic medications.

METHODS:

This cross-sectional, intensive monitoring (patient interview, case record form review and clinical examination) study was conducted in patients taking antipsychotic drugs irrespective of duration for the development of movement disorders. The psychiatrist used Modified Simpson-Angus Scale score (10-item scale), Barnes' rating scale and Abnormal Involuntary Movement Scale to diagnose parkinsonism, akathisia and tardive dyskinesia, respectively. We assessed movement disorders for the preventability and seriousness.

RESULTS:

The overall prevalence of antipsychotic induced movement disorders was 5.67% (95% CI: 4.19-7.62). The prevalence of parkinsonism, akathisia and tardive dyskinesia was 5.10% (95% CI: 3.71-6.98), 0.85% (95% CI: 0.39-1.84) and 0.57% (95% CI: 0.22-1.45), respectively. There was a trend of high proportions of movement disorders in extreme of age group, female gender, patients treated with conventional antipsychotics, on poly therapy, patients of epilepsy with psychosis, schizophrenia and bipolar mood disorder. The movement disorder was lowest with quetiapine (2.02%).

CONCLUSIONS:

The higher use of atypical antipsychotics had reduced the occurrence of movement disorders in our setup.
