Does Anyone Know What Movie This is? - description of alzheimer

I do not remember the title of a film I saw in the mid to late 90s. It was a fictional story of a group of elderly patients with dementia (Alzheimer's disease may have been, I'm not sure) and a doctor or a doctor who found what she thought of a Priest. In the movie, people are cured for a short time, but not for some reason the funds, and they all returned to their dementia. I know it's a very bad description, but someone has an idea what could be the movie?
Thank you!
