A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
The age groups most at risk for TBI are children ages five to nine and adults over age 80, [9] and the highest rates of death and hospitalization due to TBI are in people over age 65. [140] The incidence of fall-related TBI in First-World countries is increasing as the population ages; thus the median age of people with head injuries has increased.

Alzheimer's disease (AD) is a progressive, neurodegenerative disease characterized by dementia, memory loss, and deteriorating cognitive abilities. Research suggests an association between head injury in early adulthood and the development of AD later in life; the more severe the head injury, the greater the risk of developing AD. [1]
According to the Centers for Disease Control, about 1.5 people die each year from a concussion in the US; [need quotation to verify] in most of these cases, the person had received another concussion previously. [13] In the presence of second-impact syndrome, the mortality rate is at best 50% when diffuse cerebral swelling occurs. [44]
