Mild Brain Injury Symptoms and Causes
Mild traumatic brain injury, also known as concussion, minor head trauma, minor TBI or minor head injury, occurs when a sudden trauma causes damage to the brain. Mild traumatic brain injury is the most common type of TBIs. A person with a mild traumatic brain injury may remain conscious or may experience a loss of consciousness for a few seconds or minutes. Even though MRI and CAT scans are normal, mild traumatic brain injury can cause symptoms such as cognitive problems, fatigue, headache, difficulty thinking, memory problems, attention deficits, mood swings and frustration, dizziness and sleep disturbances.
