I know a few very intelligent people who were still actively involved in lives that required logical thinking and reasoning when they were diagnosed with dementia. Puzzles would never have helped. But then there is my MIL, who has stopped doing anything that requires logic or reasoning. She is the poster child for use it or lose it, and she’s losing it. What I hope to avoid by continuing to do things that challenge my brain is to keep what has happened to MIL from eventually happening to me.
