OBJECTIVE: We studied the prevalence of akathisia and its relationship to a number of sociodemographic and clinical factors in a population of Chinese inpatients with Schizophrenia. METHOD: Six-hundred and forty-five patients were recruited for the study. Akathisia was assessed using the Barnes Akathisia Rating Scale (BARS), dyskinesia by the Abnormal Involuntary Movement Scale (AIMS) and extrapyramidal side effects (EPSE) were assessed by the Simpson-Angus Rating Scale (SARS). RESULTS: Only 35 (5%) patients were assessed to have akathisia. There was no gender or ethnic difference in the rates of akathisia. However, the majority of the patients (65%) were receiving an anticholinergic agent at the time of the study. CONCLUSION: Our findings of an overlap between TD and EPSE support the suggestion that there may be a common vulnerability for these movement disorders. The finding of a low rate of akathisia among our Asian patients suggests an inter-ethnic difference in the vulnerability for the development of akathisia. However, comparing our results with the rates reported from other countries may be hampered by the diagnostic and methodological differences across studies.
Due to its low profile for extrapyramidal side-effects, quetiapine has become an alternative to clozapine in the treatment of dopamimetic psychosis in patients with Parkinson's disease (PD). We describe the case of a patient with PD who developed severe akathisia, a common complication with classical antipsychotics, with quetiapine.
Very early in the process of diagnosing abnormal involuntary movement (AIM) disorders, one can be rewarded by keeping a high index of suspicion for possible drug-induced causes, not only through a complete list of current medications, but also identification of the drugs the patient used to take and other possible offending medications that might be available from family members and other sources. Among drug-induced movement disorders, antipsychotic drugs and other dopamine receptor blocking agents occupy a central place. Their various acute and tardive motor complications provide the template of this short review. Movement disorders caused by antidepressants, lithium, antiemetics, antiparkinsonian agents, anticonvulsants, calcium channel blockers, sympathomimetics and others are only briefly covered in table form.
