Traumatic Brain Injury Linked to Suicide Risk

by Diane Domina Senior Content Production Editor

Researchers in Denmark conducted a registry-based study to determine whether there was a link between traumatic brain injury (TBI) and increased suicide risk, results of which were published in JAMA.

The researchers looked at 34,529 deaths by suicide over a 35-year period, using data from national registries, and found that people who were treated for a traumatic brain injury had a higher risk for suicide than people in the general population who were not treated for TBI. Overall, 3,536 (10.2 percent) of the people in the study who had committed suicide had been treated for concussions, skull fractures, and structural brain injuries. Suicide risk was highest in those who had sustained severe injuries within six months of hospital discharge, according to the researchers.

This observational study confirmed previous research linking a history of TBI with higher rates of self-harm, suicide, and death from all causes.
