Traumatic Brain Injury Open Access Articles

Traumatic brain injury (TBI), a sort of acquired brain injury, occurs when a sudden trauma causes damage to the brain. TBI may result when the top suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue. Symptoms of a TBI are often mild, moderate, or severe, counting on the extent of the damage to the brain. A person with a light TBI may remain conscious or may experience a loss of consciousness for a couple of seconds or minutes. Other symptoms of mild traumatic brain injury include headache, confusion, lightheadedness, dizziness, blurred vision or tired eyes, ringing within the ears, bad taste within the mouth, fatigue or lethargy, a change in sleep patterns, mood or behavioral changes, and trouble with memory, concentration, thinking or attention. A person with a moderate or severe TBI may show these same symptoms, but can also have a headache that gets worse or doesn't get away, repeated vomiting or nausea, seizures or convulsions, an inability to awaken from sleep, dilation of 1 or both pupils of the eyes, slurred speech, numbness or weakness within the extremities, loss of coordination, and increased confusion, restlessness, or agitation.
