Traumatic brain injuries are classified according to the severity and mechanism of injury: Mild: person is awake; eyes open. Symptoms can include confusion, disorientation, memory loss, headache, and brief loss of consciousness. Moderate: person is lethargic; eyes open to stimulation.
People with traumatic brain injury (TBI) commonly report problems with balance. Between 30% and 65% of people with TBI suffer from dizziness and disequilibrium (lack of balance while sitting or standing) at some point in their recovery. Dizziness includes symptoms such as lightheadedness, vertigo (the sensation that you or your surroundings are moving), and imbalance. How bad your balance problem is depends on many factors: 1  How serious your brain injury is. 2  Where in your brain you were injured. 3  Other injuries you had along with your brain injury. For example, in a motor vehicle crash, you could suffer a TBI, cervical spine injury, and rib and leg fractures.
