What typically causes a Traumatic Brain Injury (TBI)?

A Traumatic Brain Injury (TBI) is primarily caused by a bump, blow, or jolt to the head. This type of injury occurs when an external physical force impacts the skull or the brain itself, leading to potential damage to the brain tissue. These forces can occur in various scenarios, including falls, sports injuries, vehicle accidents, and combat-related injuries. The sudden movement of the brain inside the skull can cause bruising, swelling, or tearing of brain tissues, resulting in a wide range of physical, cognitive, and emotional symptoms.

Understanding the mechanics of a TBI is crucial in managing and preventing these injuries effectively. The other options listed may relate to brain health or function, but they do not directly cause traumatic injuries in the way that a physical impact does.
