Concussion Protocol
What Causes a Concussion?
A concussion, also referred to as a Mild Traumatic Brain Injury (MTBI), is a brain injury caused
by the brain impacting the inside of the skull. This impact can damage brain cells and change how they function,
leading to a variety of symptoms—physical (e.g., headaches, dizziness), cognitive (e.g., memory issues), and emotional
(e.g., depression). Concussions may result from blows to the head or body during sports and other activities.
