A Traumatic Brain Injury (TBI) occurs when an external force causes damage to the brain. This can happen due to incidents like falls, car accidents, or sports injuries. Symptoms may vary widely, ranging from mild concussions to severe brain damage, affecting cognitive functions, emotions, and physical abilities. Diagnosis typically involves medical imaging, such as CT scans or MRIs, to assess the extent of the injury. Treatment options may include rest, medication, and rehabilitation therapies. Early intervention is crucial for improving recovery outcomes and minimizing long-term effects on daily life.
