Apparently, there was a badly done photoshop after the video of Trump's (very real) dysfunctional exit from the golf cart last week:

That said, he DOES have both balance issues and gait problems on the right side that result in foot drop and related strange movements. I am among those who strongly believe that is a result of a progressive (albeit the slower progressive) form of frontotemporal dementia (FTD), which, along with gait problems, but can exacerbate issues of narcissism, grandiosity, sadistic thoughts/behavior, angry outbursts--likewise verbal issues (reduced vocabulary over time, repetitive speech, phonemic issues (misusing words that sound like others), etc. There are rapidly progressive forms, but it can progress over a dozen or more years (Trump really started showing subtle signs in 2015). It has a hereditary component (his father was diagnosed with Alzheimer's before death, but in the years since, a lot of progress in diagnostics has occurred, so it is possible an FTD diagnosis could have been missed). At any rate, when I see a video of him, I largely mute so that I can watch his movements and facial tics (and not be tortured with his speech). His rallies already confirmed the speech and ongoing phonetic issues were progressing. Regardless, he does have some consequential health issues not reported, and I am convinced some are central neurological.
