Document Summary

Concussions can arise from contact between brain and the skull and rotational forces. Concussions usually impact frontal and temporal lobes the most: frontal lobe = executive and high-level cognitive function. Repeated damage could cause long-term depression and anxiety: temporal lobe = memory and language function. Contre-coup more likely to occur on side of cortex or frontal lobe: less likely to impact occipital lobe than frontal lobe. Once one gets a concussion, they are much more likely to get a concussion again. Concussions really are a mild-traumatic brain injury. Brain atrophy is visible in former nfler"s compared to healthy individuals of same age that didn"t suffer from cte: ventricles are also much bigger in cte brain than a normal brain. Thought to be result of repetitive brain trauma that occurs with or without symptomatic concussion. Plaques and tangles are distinct from other dementias in sulci of the brain at microscopic level.
