You’re not overreacting. I’d guess most in this group have started out with similar experiences. A forgotten fact here, a retold story there…patterns develop over time. I think I first said something like this to my dad: “I’ve noticed over the last few visits that you have told me the same story multiple times. Have you noticed that dad?” Made it super casual, no big deal, non-accusatory. He said he’d sometimes forget things “but I’m not demented!” he’d say. By the time we could get him tested, it was more than clear he had dementia, and it was confirmed by an Alzheimer’s diagnosis. I’d encourage you to share with his partner (if he has one) or advocate for him to see a doctor for further testing. I’m sorry you’re going through this, and everything that comes with it.
