Over 2 million concussions, also known as mild traumatic brain injuries (TBI), occur each year. They are most often due to falls, slips, motor vehicle accidents, and sports-related injuries. Many veterans develop TBIs as a result of blast exposures related to their military service, and concussions can also be the result of a fight, assault, or domestic violence.
Fortunately, the vast majority of TBIs are mild and don't require hospitalization. Doctors usually tell patients to wait for time to pass and some prescribe psychiatric medications if symptoms are severe. Post-concussion symptoms can include nausea, headaches, light and sound sensitivity, and increased irritability. These symptoms can linger for months or even years, interfering with the ability to function at school, work, and home.
