Agitation/frustration like calling a reporter a pig or flipping off a protester?
Slurred speech, difficulty recalling names, words, places, etc. plenty of video of this.
Loss of spacial awareness like wandering into the roof of the White House or needing to be directed when meeting the leaders of Japan.
Weight gain
Paranoia? Just read his truth social rants…
Difficulty sleeping? Like staying up all night posting hundreds of truth social messages and then falling asleep at work during the day?
Walking issues? We’ve seen that. He couldn’t walk a straight line when meeting Putin.
Incontinence? Diaper rumors aside, he’s got a piss bag strapped to his leg.
Memory problems? Like making up stories whole cloth and believing them?
