A concussion is a brain injury that can be caused by a blow to the head or body that disrupts normal functioning of the brain. Concussions are a type of Traumatic Brain Injury (TBI), which can range from mild to severe and can disrupt the way the brain normally functions. Concussions can cause significant and sustained neuropsychological impairment affecting problem solving, planning, memory, attention, concentration, and behavior.
Concussions are one of the most commonly reported injuries by individuals of all age groups who participate in sports and recreational activities. People with hazardous or dangerous jobs, such as construction, law enforcement, first responders, and professional drivers, account for roughly 40% of emergency room visits due to head trauma. Over 80% of head trauma in senior citizens are due to falls. While many of these injuries may be considered mild, they can result in serious health consequences, such as impaired thinking, memory problems, emotional or behavioral changes, and even death.
Second-impact syndrome occurs when a person sustains a second concussion while still experiencing symptoms of a previous concussion. It can lead to severe impairment and even death of the victim.
Quick Facts
