Traumatic brain injury (TBI) is a major cause of disability and death worldwide, with significant implications for individuals, families, and society. TBI can result from a variety of causes, including motor vehicle accidents, falls, sports injuries, and physical violence.

The severity of a TBI can range from mild, such as a concussion, to severe, with lasting and debilitating effects on cognitive, physical, and emotional functioning. Symptoms may include headaches, dizziness, difficulty concentrating, memory problems, mood changes, and impaired motor skills, depending on the location and extent of the brain damage.

Ongoing research aims to better understand the mechanisms of TBI, develop effective treatments and rehabilitation strategies, and identify interventions that can mitigate the long-term consequences of this type of brain injury.
