Science writer: The deterioration of cognitive faculties associated with Alzheimer's disease is evidently caused by the activities of microglia—the brain's own immune cells. ███ ███ ██████ ████ █████████████ ███ ██ ██████ ██ ████ █████████████████ ██████ ████ ██ ███████████████ █████ ████████████ ████████ ████ ███████████ ███ ██████ ██ █████████ ███ ███████ ██ ████ ███ ██████ █████ ██ ███████████ ███ █████ █████████ ███ █████████ ██████ █████ ███████ ████████ ██ █████████ ███████ ████ ███████ ███████████ ███████ █████ ██████ ███████ █████████ ███ ███████ █████████ ██████████
Summarize Argument
The author concludes that the deterioriation of mental faculties associated with Alzheimer’s is caused by microglia. This is based on the fact that this deterioriation can be slowed by acetylsalicylic acid. In addition, microglia attack certain protein deposits that build up in people with Alzheimer’s, and in the process the microglia damage healthy brain cells.
Notable Assumptions
The author assumes that acetylsalyclic acid’s slowing of deterioration involves slowing or otherwise affecting the activity of microglia.
