Document Summary
Mitosis - & microglial cells also die after serving a function. Dead one has to be replaced by live one. About 2/3 of aids patients develop aids dementia. The loss of neurological control from nonfunctional neurons. Most common type of dementia is called senility [old people] . Worst example of dementia alzheimer"s [also in elderly people] just getting old. A virus called hiv [human immunodeficiency virus] Hiv destroys a key cell in immune system [t helper cell] Can also destroy macrophages & some cousins [microglial cells] Hiv can get into the cns gets across the blood brain barrier. After attacking the microglial cells- kills; lose clean up cells. Neurons & other glial cells basically become sick from exposure to metabolic wastes that aren"t being cleaned up. When neurons become toxified [poisioned], they don"t work. Brain is the most complex organ that you have but the only one that you have control.
