Michael Fralick, Eric Sy, Adiba Hassan, et al. (2018). Association of Concussion With the Risk of Suicide. A Systematic Review and Meta-Analysis. JAMA Neurol. Published online November 12, 2018.
Systematic review and meta-analysis found a 2-fold higher risk of subsequent suicide among more than 700 000 patients diagnosed with concussion and/or mild TBI, compared with more than 6.2 million individuals who had not been so diagnosed. Experiencing concussion and/or mild TBI was also associated with a higher risk of suicide attempt and suicidal ideation.
These results suggest that experiencing concussion and/or mild TBI is associated with an increased risk of suicide.
