I don't know about the 'when' with Mom. She did cut out the caffine and the walking after Dad had his stroke----BUT so has Dad been without these things! I figure some people (for whatever reason) are just more likely to get this. Do I think that some things can help or hurt---sure! I figure I now need to drink coffee with chocolate syrup while walking with a group of people! LOL! Hey that would get me all but the spice in a single swoop! LOL! I have always thought that Mom's inability to hear had a direct bearing on her dementia. Maybe not, but the confusion that not hearing had to cause could definitely cause you to think/act in a weird way. Who knows. I don't think the brain games will ward it off unless you are a total slug who does nothing. Just living is a 'brain game' constantly! I think my brain is too overworked most of the time! LOL! Ok, enough of this 'puzzle' that has no answer! Love you all, Jeanie
