Is concussion and/or mild traumatic brain injury (TBI) associated with a higher risk of suicide? This 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.
