Association of Concussion With the Risk of Suicide

Abstract

Concussion is defined as a transient disturbance of neurologic function caused by acute trauma.¹ Concussion is the most common form of traumatic brain injury (TBI), with approximately 4 million concussions occurring each year in the United States.¹ It is increasingly recognized as an injury affecting military personnel.^2,3 For approximately 80% of affected individuals, neurologic symptoms resolve within 7 days of injury.¹ However, up to 25% of patients experience chronic neuropsychiatric symptoms, including anxiety and depression, that may last years after the initial injury.⁴
