Association Between Traumatic Brain Injury and Risk of Suicide.

ABSTRACT:

Importance

Traumatic brain injuries (TBIs) can have serious long-term consequences, including psychiatric disorders. However, few studies have assessed the association between TBI and risk of suicide.

Objective

To examine the association between TBI and subsequent suicide.

Design, setting, and participants

Retrospective cohort study using nationwide registers covering 7 418 391 individuals (≥10 years) living in Denmark (1980-2014) with 164 265 624 person-years' follow-up; 567 823 (7.6%) had a medical contact for TBI. Data were analyzed using Poisson regression adjusted for relevant covariates, including fractures not involving the skull, psychiatric diagnoses, and deliberate self-harm.

Exposure

Medical contacts for TBI recorded in the National Patient Register
