Document Summary
Stroke: an interruption of blood ow to the brain that kill brain cells and causes neurological symptoms to appear suddenly. Ischemic: de cient blood ow to the brain due to a clot. Can be treated with the drug t-pa within 3 hours. Tissue plasminogen activator (t-pa): drugs which breaks up clots and allows normal blood ow to the affected region. Is administered after an ischemic stroke but can aggravate cell death in a hemorrhagic stroke, making proper diagnosis important. Ex. a story about a man named r. s. who had an ischemic stroke, while he recovered to be able to preform most pre-stroke activities he became apathetic. He was no longer talkative, and no longer enjoyed the same activities. Hemorrhagic: stroke caused from a burst vessel bleeding into the brain. The brain has ~85 billion neurons that engage in information processing, and 86 billion glial cells which support neuronal functioning.
