Dementia is more than a slowing down, especially in the upper 70s and into your 80s where that's prevalent as is. Trump definitely shows more of it than Mueller does. Mueller clearly, while slow to respond and maybe a bit hard of hearing, knows where he is and responds clearly and in kind and has his wits about him. Trump, while still pretty lucid, shows a lot more genuine confusion and erratic behavior. I'm not saying either one of them has it, but out of the two, Trump is definitely more within my understanding of it. I have had family/family friends with it to varying degrees, but like most mental health problems it's varied per person. But from my perspective Mueller is just... you know, older. The processing speed is a bit slower but the end result is still sound and solid.
