You know people wirh Alzheimers can be in great shape except for their mind. My dad was the star patient at the nursing home, friendly and amiable...they loved him. He wasn't like that normally. He was in good physical shape and did well physically until a bout of shingles hindered this good health. It is tough to see your parent go through this.
Maybe Trump will release some cures for this disease...I know they exist. God bless your family...your mom is lucky to have you. I have family that works in a nursing home and one is a hospice social worker and many older people have no family...it is pretty sad. You mom will always be able to feel your love even when she doesn't know who you are.
