My Mum and Dad moved in with us a couple of years ago as they were struggling after Dads stroke. Unfortunately Mum died last year from pulmonary fibrosis - we only got a diagnosis a few weeks before she died. Just before Christmas Dad seemed very off with us but as I had seen his moods change with my Mum I didn’t really say anything (he could be quite nasty to her) as he usually settled down. Christmas Day was awful he accused me of lying to him for 30 years but wouldn’t explain about what, my husbands daughter visited us and he called her the most awful names (he saw her a few weeks before and there was no problem). Ended up with him having his dinner on his own. He told me he wished I were dead. Since then he won’t speak to us, just sits in his room, or goes in the garden for a walk - but he just acts as if we are not there. Once or twice when he has needed help he will talk but once everything is sorted he just stops talking. He mentioned Christmas to me the other week and berated me for having ‘those people’ in the house, called me a liar and said I don’t like you. I have been to see the doctor and have made an appointment for him to see him. In the mean time I just feel really upset and helpless - he spends all his time on his own. Now I look back I can see that he has been experiencing mood swings for a while and they make him nasty. He also won’t let me wash his clothes, he washes them (sort of) in the shower. He will also dry a plate, wipe down surfaces and the floor all with the same cloth! I understand that he is probably suffering from depression but I am also wondering if he has mild vascular dementia. Just wondering if any of this sounds familiar
