What defines a traumatic brain injury?

A traumatic brain injury (TBI) is primarily defined by the mechanism of injury involving a force applied to the skull and brain. This type of injury can occur due to various circumstances such as falls, vehicle accidents, or any event that causes the head to suddenly hit an object or vice versa. The focus is on the impact that disrupts normal brain function, and this can happen even without a direct injury to the face or external skull.

Understanding this definition emphasizes the importance of identifying any situation where the head may be subject to significant force. It is also crucial to recognize that TBIs can happen outside of sports contexts, countering any assumptions that they are limited to athletic activities. The consequences of TBIs can vary widely in severity and can lead to a range of cognitive, physical, and emotional symptoms, highlighting the importance of appropriate diagnosis and treatment.
