Solution

Concussion is mild traumatic brain injury that results from a blow to the head, or a fall, or any injury that shakes the brain inside the skull. The brain temporarily loses some of its functions.

* The physiology behind concussions is either stretching of axons or changes in the flow of ions in the neurons.

* Symptoms are either behavioral or cognitive, but physical symptoms of damage are rare to diagnose. Amnesia, loss of conciousness, impaired congnition skills, headache, and emotional changeability are the most common symptoms.
