Hi there. Both my parents are in their 70s and within the last year I first noticed Dad behaving oddly and now within the last six months, it's Mum too. Having spoken to my siblings, we all seemed to have noticed various things, but it didn't all pool together until we sat down and talked. Only today, Mum completely blanked out something that happened an hour before She genuinely seemed to be unaware of what happened and I was left stumped by it. It's happened several times before. They both get agitated and argue about things they swear they have told one of us, even though they clearly haven't or vice versa....they swear we didn't tell them something but we did. Dad has had a few arguments with each of us at some point over various confusions or misunderstandings. He has difficulty with visual perception and cannot perform tasks like he used to. Something like putting up a shelf is difficult now, as he can't grasp the usual technique and if he gets it on the wall he thinks it's level and will argue the point. Mum lost her way in London in streets that she grew up in and couldn't remember her way around. How do I deal with this? Do I speak with the GP first to ask how to approach my parents? They will not think that anything is wrong and I know that perhaps some of their symptoms could be related to medications perhaps? It's all rather worrying. I am thinking we need to write down all the symptoms and dates.
