During a car accident, the impact may cause the head to hit the steering wheel, window, or headrest with enough force that it causes a concussion. A concussion is a type of traumatic brain injury (TBI) that causes the brain to move quickly back and forth within the skull causing chemical changes in the brain.  Symptoms of concussions include dizziness, headaches, neck pain, memory loss, visual disturbances, and more.  Concussion therapy helps correct these symptoms with exercises for the head and neck as well as specific exercises for the eyes, balance, and adapting the brain to sensitivities.  When treating concussions, it is key to allow for ample rest time as well as strategic exercise to work the brain but not fatigue it too much. Proper nutrition should also be considered.
