My mother in law within the last month has completely lost her memory. She has stuggled within the last year or so with remembering her grandchildren names, etc. Her mother had a significant stroke at about 90 and was hospitalized in France until her death. My mother in law recently tried to attend her grand daughters graduation from high school and spent the night with her daughter and she was very disoriented and swore she had never been in her home. The day of graduation she was brought to our daughters school and she cried that she was attending her own funeral. She is 93 and the last year has been very difficult for the family - what, if anything, can we do to help her? She and her husband live alone because she has said she would not leave her home but we are concerned that this isn t safe. Please provide some direction
