Abstract

Administrative data from a Canadian province were accessed to assess the association of psychotic disorders with multiple sclerosis (MS). Physician-assigned ICD-9-CM codes were used to classify MS and psychotic disorder status. A significant association was observed. Additional research is needed to determine the clinical importance and treatment needs of this population.
