My dad has Alzheimer's he was getting really bad.  he was going outside in the middle of the night without clothing and pulling weeds.  he couldn't talk to anyone, he wouldn't leave the house he wouldn't talk on the phone, basically he was a zombie.  my sister's son was prescribed Deplin but refused to take it so she had a large expensive supply.  I researched online and found that it might help my dad.  we told my dad's doctors what we were going to do, they didn't think it would help him at all but said it won't hurt him either.  so we started giving him the Deplin.  within 30 days of taking it there was such an improvement of my fathers quality of life, we were all so happy!  the longer he's been taking it the better he's getting.  I'm not saying it's a cure for alzheimers in any way, but what I am saying is that it can improve the patients quality of life.  his doctors are now deciding that there is such an improvement that they will now prescribe it for him.  it hasn't been an easy road convincing the doctors of the help but eventually they can see the results.  we are so happy we found Deplin and happy that my father is doing so much better!
