Is it coincidental that both Reagan and Thatcher had dementia?

19. I am pretty sure that Maggie didn't have dementia when in office

Her type of dementia was different from Reagan's. He had Alzheimer's, which can begin insidiously and progress slowly. She had a series of small strokes which affected her cognition -before eventually having a bigger stroke that killed her. Before her strokes, there was no sign of any cognitive problem.

Also she was sharp, politically shrewd and industrious as a Prime Minister, even if her industry was entirely in the wrong causes. Reagan was obviously unable to work a full day; she was constantly on the go, getting only 5 hours of sleep per night. Reagan was obviously largely 'handled' by others; she was a control freak unable or unwilling to delegate. He made lots of gaffes and verbal fluffs, which on hindsight should have been a warning sign in someone who had, after all, once been an actor and therefore, whatever his overall IQ, must have at one time had the ability to learn and remember his lines. She made no more such fluffs than any other politician.

She was not lacking in a brain. She was lacking in a heart.
