Suicidal ideas in stroke patients 3 and 15 months after stroke

Patients with stroke may have an increased risk of suicide. We sought to examine the frequency and clinical correlates of suicidal ideas 3 and 15 months after stroke. The study group comprised 286 of 486 consecutive patients aged 55-85 years who at 3 and 15 months after ischemic stroke completed a detailed medical, neurological and radiological stroke evaluation, structured measures of cognition (Mini Mental State Examination), emotion (Beck Depression Inventory, BDI), disability (Rankin scale), and assessment of dependent living. Suicidal ideas were present in 9.8% (n = 28) at 3 months' follow-up and in 14.0% (n = 40) at 15 months' follow-up. The patients with suicidal ideas were more depressed measured by BDI both at 3 (17.0 vs. 7.9, p < 0.001) and 15 months (20.5 vs. 8.5, p < 0.001) after stroke compared to the patients without suicidal ideas. Patients with suicidal ideas had more often a history of a stroke already before the index stroke (35 vs. 18.3%, p = 0.0154), right-sided stroke (60.0 vs. 41.9%, p = 0.0323), they were more disabled according to the Rankin scale (2.4 vs. 1.9; p = 0.0035) and more dependent in living (45.0 vs. 27.2%, p = 0.023) 15 months after stroke. An independent correlate of suicidal ideas 15 months after stroke was history of prior stroke (OR 2.4; 95% CI 1.14-4.97) in logistic regression analysis. The frequency of suicidal ideas increased with the time elapsed from stroke. Recurrent strokes, depressive symptoms, more disabling stroke and right-sided stroke correlated to suicidal ideas at 15 months after stroke. Early identification of these risk factors may lead to effective therapeutic intervention. Copyright (C) 2001 S. Karger AG. Basel.
