For the past 5 years or so she has been more forgetful and repeats herself several times a day. She often inaccurately rewrites past events. Still she keeps track of her appointments and finances and living alone she eats healthy and has good hygiene and remembers people's birthdays. My brother and I get worried about her forgetfulness about conversations we have had and whether that means she is headed for dementia or alzheimers. I wonder if at 92 this forgetfulness is "normal". Can you help me with this?
