The Relationship between Risk Factors for Affective Disorder and Poststroke Depression in Hospitalised Stroke Patients

Abstract

The influence of psychiatric risk factors on the development of depression following stroke was examined in 88 patients undergoing inpatient rehabilitation. In this sample, 34 patients (38%) had a diagnosis of major or minor depression. Older age and a personal or family history of affective or anxiety disorder were associated significantly with major depression. Minor depression was more common among males and those patients with greater physical disability. Severity of depressive symptoms was associated with a personal or family history of affective or anxiety disorder and higher pre-stroke personality neuroticism. We conclude that certain psychiatric risk factors for affective disorder are strongly associated with poststroke depression. The implications of these findings for anticipating and managing poststroke depression are discussed.
