I can't, and it will sound like conteo, but Trump likely suffered a couple of strokes and he's brought back to a reasonably active state every time. I don't know what happened to Mitch McConnell, but it is probably very close to necromancy. Treatment like this doesn't really exist for the regular population. If you get a stroke, you're out of action for at least several months, probably never to come back as you were before, ever.
