Very frustrating! I had to get DH to a neurologist out of the area that specializes just in AD and other dementias. His Dr. then started his clinic where he only conducts clinical trials to try to find a cure. Maybe you could find someone like that in your area?My Aunt had it at least 11 years when she passed away. Idk how long Mom had it because I was out of state and my parents never mentioned it. I believe my Dad had it too, but never was tested. I have been tested but the doctors say my memory is fine. It is NOT. So frustrating.
