My dad is very intelligent, has a PhD, worked in a professional role all his life, was a big reader. He is now 87 and in excellent physical health, but mentally is definitely a lot slower.
His refrain about almost everything (booking tickets, setting up a new toy for my DD, organising anything) is ‘it’s too complicated’ (even when I am doing something myself, if it takes more than 5 mins dad will be proclaiming ‘ that looks very complicated!’). I have also noticed that he doesn’t read instructions properly and then ends up getting in a muddle and blaming the company (‘ the instructions are far too complicated, it’s ridiculous!’) I usually end up doing things for him to avoid this, although he gets upset if he feels undermined, so I have to tread carefully!
My question is, could this be a sign of dementia? Or is it just normal cognitive decline at his age? His memory is also terrible but he is able to answer cognitive tests with no problem (no, my dad is not Donald Trump!) Any advice welcome.
