Does prestroke depression increase the hazard of suicide in stroke patients?
Hazard Ratio: 2.2
Prestroke depression significantly increases the risk of suicide in stroke patients, particularly within the first 2 years post-stroke.
Suggests enhanced suicide vigilance in stroke survivors with prestroke depression; leaves open whether screening or interventions improve outcomes.
The authors studied the prevalence of stroke among suicide victims and whether prestroke depression had influence on suicide process. The authors used a comprehensive database of all suicides (N=2,283) committed in Northern Finland over a period of 15 years with information on all hospital-treated somatic and psychiatric disorders. Of the total suicide data population, 3.4% had suffered from stroke. After adjusting for age and sex, prestroke depression in stroke victims increased the hazard of suicide up to 2.2-fold compared to victims with stroke but without any lifetime depression. The high-risk period for suicide was 2 years after stroke.

Forsström et al. (2010) conducted an observational in Suicide (n=2,283). Prestroke depression vs. No lifetime depression was evaluated on Hazard of suicide (HR 2.2). Prestroke depression in stroke victims increased the hazard of suicide up to 2.2-fold compared to stroke victims without lifetime depression, with the highest risk period being 2 years post-stroke.
