Abstract
BACKGROUND: Huntington's disease (HD) patients are at significantly higher risk of suicidal behavior, and associated cognitive and behavioral factors play an important role. Impulsivity is commonly thought to be a risk factor, but does not completely account for all suicide attempts. OBJECTIVE: To provide clinical evidence that perseverative behavior may precipitate suicide attempts in HD. METHODS: Case review of four HD patients who attempted suicide. RESULTS: Each patient demonstrated a clinical history of perseverative behavior, and endorsed perseveration on upsetting thoughts leading up to their suicide attempts. The attempts were planned in response to these ruminations. CONCLUSIONS: The patients in this series experienced uncontrollable distressful thoughts prior to their thoughtfully planned suicide attempts. These patients did not appear to act impulsively in their decision to attempt suicide.
