Traumatic brain injury (TBI) is a serious public health issue that refers to damage to the brain caused by an external force. This can result from events such as car accidents, falls, or acts of violence. TBI research aims to better understand the mechanisms of injury, develop improved diagnostic tools and treatments, and prevent further damage to the brain. Common areas of study in TBI research include neuroimaging, cognitive rehabilitation, and biomarker development. TBI can have significant long-term consequences, including cognitive impairments, emotional disturbances, and physical disabilities, making research in this area critical for improving outcomes for affected individuals.
