Namenda and Exelon have improved my 97 yo mother's function to the point that a person casually talking to her might not notice she has any problem at all. We do, of course, but she is considerably improved. The stuff is horribly expensive, however.
Prevagen is only $50/month, and works for all sorts of memory and behavior issues.
Even helps kids get better grades in school, and reduces the frequency of migraines.
