My mom is 47 years old and is very forgetful and recently got a concussion. It's basically a forgone conclusion that at some point in the future she is going to have some memory problems (Alzheimer's) runs in her family. I have been doing research on the benefits of playing chess and found a study that says adults who play chess regularly have a lower rate of Alzheimer's and Dementia. She has literally zero knowledge of the game, but has agreed to let me teach her since I am doing it not for selfish reasons. Does anyone have any suggestions for teaching adults chess?
