Are Trump and his followers demented?

So here's a medical question I've been pondering for a while now*: Is there some gene or something about some people's brains that makes them unable to discern or recognize lies or separate fact from fiction?

And guess what? There is!

According to a recent study conducted by scientists at the University of California, San Francisco, an inability to detect lies -- and sarcasm -- may well be the result of damage to (or something affecting) the frontal and temporal lobes of the brain. It even has a name, frontotemporal dementia, and the condition affects adults at a younger age (typically 40 - 70) than other forms of dementia, such as Alzheimer's.

Another sign of frontotemporal dementia? Socially inappropriate and/or compulsive behavior.

Sound like anyone orange you know (or any of his supporters)?

Pretty sure dementia would fall under the list of reasons to enact Section 4. of the 25th Amendment of the Constitution. And an MRI, which, when I last checked, was nonpartisan, would determine if Trump (or anyone else) suffered from this form of dementia.

Sadly, there is no cure for this disease... until 2020.

UPDATED: A big THANK YOU to my mother for sending me this New Yorker article titled "Why Facts Don't Change Our Minds," which scientifically explains the Trump phenomenon -- and why our species may be doomed.

*But especially since Trump secured the Republican nomination for president.
