My grandma is 85, she has had a sister with dementia, and we've recently noticed that she has been forgetting things lately, repeating the same thing within an hour sort of thing. She's been forgetful for a little while but it seems to have gotten worse since my grandad passed away in October. Is it possible that this could be the early signs of dementia, particularly with it being in the family? And could it have been made worse or triggered by my grandad passing? They were together every day for over 60 years, she was understandably devastated at the loss.
