"The Science of Alzheimer's" from Time



Time Magazine has published a supermarket coffee table paperback “The Science of Alzheimer’s: What It Is, How It Touches Us, Hope”.  18 chapters divided into the three sections named, 96 pages.

There are many writers. Jeffrey Kluger writes the introduction and appears to be the lead writer.
The introduction calls it “The disease that steals the self.”
  
There is a chapter on early-onset Alzheimer’s.  On p. 20, there is a list of various other diseases that mimic Alzheimer’s.  There are odd sounding entities like “Lewy bodies”. 

The book covers the genetics angle, as well as many varied treatments that may delay symptoms.

The book covers the lives of some celebrities who had the disease, including, surprisingly, Rosa Parks.

The work also covers the exploding cost of care, which falls on families as nursing home custodial care is not normally covered by Medicare.  Much of the problem, however, comes from increased life spans, as people who would have died of other infirmities live long enough to get Alzheimer’s.  The disease affects women more often since women live longer.


On p. 44 there is an sidebar, “These lifestyle changes may help protect the brain as you age.”  Besides diet and exercise, there is the issue of enough sleep, and especially “be social”.  More social contact tends to preserve cognition – although that may be true of real introverts.

On p. 62 there is a paragraph “Why being single is less of an Alzheimer’s risk than it used to be”, down from 42% to 24% (for never marrieds).  That may be partly because for a minority of people, being single and involved with self-driven work actually preserves intellectual function very well, and there is more social support for less conventional lifestyles (including gay).
  
There is a lot of discussion of the science of amyloids, or tau proteins, and of how neural networks actually function in a manner analogous to Twitter.
