Buspirone's efficacy in organic-induced aggression.

The objectives of this study were to (1) identify and characterize hospitalized patients with an organic-related psychiatric diagnosis who had received buspirone therapy and (2) assess the effect of buspirone on aggressive behaviors. A retrospective medical records review was conducted on all patients who were admitted to our psychiatric/rehabilitation facility over a 36-month period and who had received buspirone therapy. Monthly behavioral therapy records were used to determine the quality and quantity of aggressive-related behaviors. Study endpoint was reached in each subject when buspirone was discontinued or when records were unavailable. Twenty subjects, ranging in age from 15 to 55 years old (mu = 26.1 +/- 9.8), were identified for study. Nine (90%) of 10 subjects for whom data were available for at least 3 months showed an improvement in behavior by study endpoint, and 6 (60%) showed at least a 50% reduction in behavioral symptoms by study endpoint. Results from this study suggest that buspirone is well tolerated and may be effective in the treatment of aggressive and other maladaptive behaviors in individuals with an organic component to their psychiatric illness, particularly traumatic brain injury. Prospective, controlled trials are needed to validate these findings.
