My mother has just been diagnosed with Dementia. MRI results said moderate dementia. I m not sure what they mean by moderate, would that be considered early stages? We have not gotten the EEG test results. She is 78 years. Has had both knees replaced. Both surgery s were very hard on her. The anesthesiologist gave her to much when she was in surgery. This happened both times they had a very difficult time waking her up, to the point we almost lost her on the 1st surgery. This was suppose to be noted in her chart. We know that after the 2nd surgery being put to sleep did affect her. So she doesn t need to be put to sleep ever again. My question what medications are available to help slow the progression of this disease, Dementia ?
