Sudden personality change in my grandfather
My grandpa has been developing some sudden personality changes. For background, he is 82, 6’4, 200 some odd lbs, and has diabetes. For the past few months, he has descended into a foul mood. He used to nr really nice, and a good guy. He has now become angry, controlling, and paranoid. He has fallen on several occasions, but refuses to use his walker or a wheelchair. If you try to get him to use his walker, or the new bathroom they had built for him, he gets mad and refuses because “I’m not a damn cripple.” He’s becoming irrationally angry over very small things. He’s also becoming controlling of my 81 year old grandma, and even went so far as to suggest that she was having an affair with her sisters husband. This was a kind, sweet, and gentle man for all of my life, and according to my dad growing up. This has all come on over the past few months, and has been getting worse over the past week. Does anyone have any ideas? My dad and I think it might be early stages of dementia.
