The Defense and Veterans Brain Injury Center (DVBIC) tracks the total number of service members throughout the Department of Defense who have been diagnosed with a traumatic brain injury (TBI). Since the year 2000, over 313,000 service members have been diagnosed with a TBI. Following a mild TBI, it is common for individuals to experience headache, sleep disturbance, difficulty with balance, reduced attention/concentration, reduced memory ability, irritability, and/or mood swings.
