Looking back, there were warning signs. Starting in his late fifties, John Alex McDonald would forget things. He would continually misplace his keys and his wallet, but he chalked it up to absent-mindedness. Then, one day, he was driving on the highway and suddenly forgot everything. Where he was. Who he was. It was 10 minutes before he remembered, and his new reality set in. PLUS, when author Ivan Coyote went to visit their 97-year-old grandma for the last time, they'd been warned that Grandma Patricia now gets things, especially people, confused. But that night Grandma Patricia knew exactly who Ivan was.
