I don't want to give you false hope but I have a relative (that I moved a long way to be near) who has dementia and was told by doctors and dementia professionals years ago it would be progressive and unfortunately that was the way it would be. There would be no reversal. Well, my relative is far better in all respects than they were years ago. I believe this had to do with the fact they went into assisted living where they got the right medication, professional care and all day stimulation. No one can explain it, one exceptional caregiver knew that it was possible, and expects more improvement, and I am totally amazed each time I visit. They wear me out each time I go as they want to walk around the facility, inside and out, for literally hours and socialize along the way with anyone we come across. When they arrived at the assisted living facility years ago they were unintelligible, could barely walk and the prognosis was dire! So you never know!
