Alzheimers

I did not know why it was called Alzheimers, so looked it up

Alzheimer's disease is named after Dr. Alois Alzheimer, a German doctor. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. He found many abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary tangles). Plaques and tangles in the brain are two of the main features of Alzheimer's disease. The third is loss of connections between nerve cells in the brain.

Although we still don’t know how Alzheimer’s disease begins, it seems likely that damage to the brain starts 10 years or more before problems become obvious. During the earliest stage of Alzheimer’s, people are free of symptoms, but harmful changes are taking place in the brain. Abnormal protein deposits form plaques and tangles in the brain. Once-healthy nerve cells lose their ability to function and communicate with each other, and eventually they die.


As nerve cells in the brain die, parts of the brain begin to shrink. By the final stage of Alzheimer’s, damage is widespread, and brain tissue has shrunk significantly.
