Document Summary
Brain and spinal cord are suspended in spinal fluid. Blow (not necessary physical point of contact (i. e. jolt)) to head, trauma to head - brain is shifted in the fluid which can lead to symptoms. 2 points in the brain that experience damage (e. g. bleeding, swelling, etc. ) from blow to head. Point of contact = coup; countercoup is opposite of coup. Subdural bleeding; sub = underneath, dural = a layer in the brain. Damage that occurs to the axon (grey body damage would be damage to the cell body) Symptoms as a consequence of a concussion vary across individual and in severity. Athletes experiencing repeated blows to head; these athletes experienced dementia. Athletes carrying e4 variant of apolipoprotein (apoe) gene might be likely to develop. Sitting around thinking about symptoms may make them worse. "push up to pain but not through it" - helps maintain neural connections and rewire to help with daily functions.
