using a devastating neurological diseases as an insult, is wrong, but using it a a reason that he shouldn’t run a country is fair.

I don’t necessarily disagree but you also run the risk of distracting from the most dangerous part about him. He is a fascist, that is what is wildly dangerous about him and as much as it is fun to make fun of fascists for being dumbshits, it isn’t a lack of mental capacity that leads to fascism. Those two things are perpendicular and as tempting as it is to equate fascism with stupidity the far more terrifying truth is that it only really equates with ignorance.

If it's a disease he's suffering from, which is not something I'm confident of. The image above chooses a particular representation of the posture caused by the disease that happens to match, but it is far from a fully representative expression of that symptom. The behavioral symptoms listed are likewise picked specifically for their fitness to Trump, and a brief search doesn't show any descriptions of the disease that go into that much detail about the associated behavioral issues. That's all to say, it's a meme, not a fact.

fair. Also, is he trying to make his Poor judgement, Loss of Empathy, Socially Inappropriate Behavior, Lack of Inhibition, Inability to Concentrate or Plan, Frequent Abrupt Mood Changers, Speech Difficulties, and Memory Loss hang in a more flattering way?

All perfectly valid reasons to deem him unfit for office, so why make up more? This and comments on his (or anyone's) appearance only distract from the multitude of very valid issues with him. I mean you only need a video of him speaking to see that he vomits verbal diarrhea at every opportunity and only cares about himself, why do we need to assign it to some malady?

Were I to believe that most people spreading this actually thought he had some form of dementia, then fine, that's a valid reason to call him unfit. But I don't believe that, and it sets a poor precedent going forward to call attention away from his open bigotry and genuinely horrific policies to bring up these invented illnesses that aren't actually going to change anyone's mind. It only serves as an insult to make people who already dislike him feel better and give his supporters and fence-sitters more reason to ignore factually founded opposition. Look forward to this for every election.

I mean all you really have to do is post quotes right from the horse's mouth. If those don't speak to his issues, nothing will.

Don't forget when Romney got beat. Romney, hey. Did you see his? I wonder if he enjoyed his flight in last night. But when Romney got beaten, you know, he stands up like you're more typical, "Well, I'd like to congratulate the victor." The victor? Who is the victor, Mitt? "I'd like to congratulate." They don't go and look at the facts. No, I don't know. He got, he got slaughtered. Probably, maybe it was OK, maybe it was. But that's what happened.

All of those things you described are the reasons why he shouldn't run the country. Why bring illness into it?
