My Dads always been difficult, selfish and stingy, but over the last few years, along with short term memory loss and general confusion, moneys become an obsession. He repeats ‘jokes’ that we should pay him for stuff like playing with the grandkids. He got angry about 30p his grandchild picked up that he said belonged to him. He started to not tip waiters (embarrassing) and makes my mum (works part time) unreasonably pay for more and more. He burdens everyone with his stinginess and mooching, trying to save every penny while we pick up the tab. He thought someone tried to pickpocket his wallet out of my mums handbag and got aggressive with my mum. It’s difficult to sympathise as it’s such a horrible trait. He’s started getting paranoid about my relationship with my mum (we’ve always been close) to the point where he follows her around trying to prevent us having time together or eavesdropping. We went out and when we came back he is standing rather ominously on the balcony like a lookout waiting for our return. He does wierd things like shaking a fizzy drink before opening it then being surprised when it goes everywhere. He has spent family days out to the seaside marching around the town looking for something he dropped only to find it in the car later on. In the evenings (when my parents stay) he gets my back up slightly by wandering around the house sometimes after saying goodnight. He often misses social cues. Does this sound familiar at all and would this possibly be mid stage? (We already had 5 years of general memory decline) He won’t see a Dr at this point. He also forgets that he’s eaten lunch at dinner time and struggles to comprehend dates.
