Document Summary

Lobe adam groh: cte chronic traumatic encephalopathy (brain injury), linked to participation in contact sports, results in: Motor neuron disease (loss of movement): cte is thought to be the result of repetitive brain trauma that occurs with/without symptomatic concussion. The brain is inside a bony structure (skull) with cerebral spinal fluid. If the skull suddenly stops, the brain will not injury. Neural forces change as a result and there is a reduction in cerebral blood flow: 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 defense and offense may experience more than. Decreased brain mass, enlarged lateral ventricles (for cerebral spinal fluid) and generalized atrophy of frontal and temporal lobes (for memory/motion control: microscopic neuropathology. Extensive tau-immunoreactive neurofibrillary tangles (nft) in the frontal lobe.
