My neighbor seems to have Alziemers, he lives alone, and I do not think he has any family...I've tried to help him as much as I can, as for as I know he has not been evaluated by a doctor, I was told that you can call 1- 800-252-5400... that will let the city know and they will send someone to his home to evaluate him, also they will follow up on what needs to be done to help him... I know if a person gets this, they sometimes do not realize they have a problem, or they refuse to go to the doctor, in which case a lot of family or friends do not know what to do...hope this helps someone else.
