Sorry, I didn't word that right. You're correct, the current literature suggests that there's a correlation between mental "exercise" and a reduced risk of Alzheimer's and other forms of dementia. However, there appears to be a link between stress and stress-related hormones and increased amyloid accumulation (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905685/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905685/), so if the amyloid theory for dementia is correct, then there's a fine line between "fun" cognitive load and stressful cognitive load.
