Traumatic Brain Injury News and Research RSS Feed - Traumatic Brain Injury News and Research

Traumatic brain injury (TBI), a form of acquired brain injury, occurs when a sudden trauma causes damage to the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue. Symptoms of a TBI can be mild, moderate, or severe, depending on the extent of the damage to the brain. A person with a mild TBI may remain conscious or may experience a loss of consciousness for a few seconds or minutes. Other symptoms of mild TBI include headache, confusion, lightheadedness, dizziness, blurred vision or tired eyes, ringing in the ears, bad taste in the mouth, fatigue or lethargy, a change in sleep patterns, behavioral or mood changes, and trouble with memory, concentration, attention, or thinking. A person with a moderate or severe TBI may show these same symptoms, but may also have a headache that gets worse or does not go away, repeated vomiting or nausea, convulsions or seizures, an inability to awaken from sleep, dilation of one or both pupils of the eyes, slurred speech, weakness or numbness in the extremities, loss of coordination, and increased confusion, restlessness, or agitation.
Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Traumatic brain injury can cause post-traumatic neurodegenerations with an increase in reactive oxygen species and reactive oxygen species-mediated lipid peroxidation. Melatonin, a non-enzymatic antioxidant and neuroprotective agent, has been shown to counteract oxidative stress-induced pathophysiologic conditions like cerebral ischemia/reperfusion injury, neuronal excitotoxicity and chronic inflammation.
