Document Summary
Cte is a long term deficit that occurs over multiple concussions. Cerebral spinal fluid is between the brain and skull and acts as a cushion. During a concussion the brain is moving really fast that shearing forces on neurons cause damages in their firing. Enlarged ventricles in the center of the brain is a characteristic of multiple concussions. Chronic traumatic encephalophathy: linked to participation in contact sports and results in: progressive decline of memory and cognition depression suicidal behaviour poor impulse control aggressiveness parkinson dementia (eventually: motor neuron disease (like als) Cte is thought to be the result of repetitive brain trauma that occurs with or without symptomatic concussion. Athletes in contact sports such as football may experience sub-concussive impacts on the order of 1400 per season. In high school, an athlete who plays both defensive and offensive may experience more than 2000 sub-concussive impacts (more for lineman and linebackers)
