Some hopeful news on the Alzheimer's front. Some interesting confirmation, too, on the regenerative powers of a stimulating environment.

My own father, though, is probably too far gone to benefit: he is unable to verbalize anymore, and has to be fed by orderlies. Fortunately, Toronto's Sunnybrooke Veteran's Hospital is an excellent facility, and like the other veterans there (he served on the front lines in WWII) he is treated with respect.
