Relationship Between Antipsychotic Medications and Cerebrovascular Disease in Patients With Serious Mental Illness.

INTRODUCTION AND OBJECTIVES: Cerebrovascular disease (CVD), especially in its asymptomatic forms, is relatively common in patients with serious mental illness (SMI). Nevertheless, the literature on this topic is scarce and sometimes contradictory. Antipsychotic medications, especially atypical agents, play an important role in the overall cardiovascular health of these patients. The goal of this study was to analyze the frequency of CVD in patients with and without SMI.

PATIENTS AND METHODS: This retrospective cohort study compared the frequency of CVD, including silent forms, in a group of patients without mental illness and without a history of taking antipsychotic medication, with another group of patients diagnosed with SMI who had received antipsychotic treatment. The 2 groups were matched for age and sex, and the mean age of the subjects in the 2 groups was 63 years.

RESULTS: The frequency of CVD was the same in both groups and it was not modified by the use of antipsychotic medications. A nonsignificant trend toward an association between CVD and prolonged use of antipsychotic polypharmacy was found.

CONCLUSIONS: In this study, in contrast to previous reports, use of antipsychotic medications and the presence of SMI were not associated with an increased risk of CVD.
