My Dad had frontotemporal dementia. My sibling and I had to deal with the consequences - until we couldn’t cope, when my Dad became properly violent.

We’re looking at Trump and let me tell you, it feels eerily family. The confusion, remembering stuff from the past but not the present, but most importantly - and that’s one of the defining trait of frontotemporal dementia - the constant aggressivity that stems from the sufferer’s incorrect world views and beliefs being at odd with a reality that everybody keeps reminding him of, that leads him to believe everybody is against him… When it gets bad enough, the person literally assaults people who contradict him out of frustration. Ask me how we know…

We see the signs in Trump. Clear as day. And I bet everybody who’s had to deal with a parent who had dementia sees the signs too.
