Understanding Traumatic Brain Injury: Signs and Symptoms

Traumatic brain injury (TBI) is a serious condition that can have long-lasting effects on a person's physical and cognitive abilities. It occurs when the brain is subjected to a sudden impact or jolt, causing damage to the brain tissue. The four most common signs and symptoms of traumatic brain injury include confusion, headaches, loss of consciousness, and memory loss. Confusion is a common symptom that can range from mild to severe and can be accompanied by difficulty concentrating, disorientation, and a lack of coordination. Headaches are a frequent symptom of TBI and can range from mild to severe. They can be accompanied by nausea, vomiting, and sensitivity to light or sound. Loss of consciousness is also a common sign of TBI and can last anywhere from a few seconds to several minutes. Memory loss is another symptom of TBI that can range from mild to severe.
