The risk of suicide increases by more than three times in the first six months after a person suffers a head injury. The consistent headaches, dizziness, and cognitive, logical memory problems that very often accompany a traumatic brain injury can lead to depression, exacerbating suicide risks.
In the study, Danish researchers estimated that the risk of suicide not only increases significantly within the first six months after the injury occurs, but also remains at least twice as high as in people with no brain injury, over the next few years. Even as long as seven years after the traumatic brain injury, persons with an injury had a 75% higher risk of committing suicide, compared to persons with no history of brain injury. Out of the more than 34,000 suicides that were studied as part of the research, more than 10% had sought treatment for brain injury.
