Everything you need to know about Donald Trump’s health amid mounting concerns

In addition to the reported physical decline, Trump’s alleged cognitive decline has been observed by his ex-confidants and experts.

John Gartner, former assistant professor of psychiatry at Johns Hopkins University Medical School, explained to a news channel that Trump’s health is visibly deteriorating.

“What we’re seeing are the classic signs of dementia, which is a gross decline from a person’s baseline and functioning,” Gartner said in August 2025.

“If you go back and look at movies from the 1980s, [Trump] was actually extremely articulate,” he continued. “He was still a jerk, but he could express himself in polished paragraphs, and now he really struggles to finish a thought, and that’s a huge regression.”

This reflects something New York magazine writer Ben Terris shared this in an episode of the Explained today podcast, in which he noted, “The way he’s trying to control the narrative, so to speak, about his health is kind of like the way he’s trying to control everything. I just feel like he’s losing some of that control.”

After a doctor noticed Trump’s signs of dementia, veteran political strategist James Carville said, “You don’t have to be a neurologist or Dr. Jonathan Reiner or anything like that. We’ve all had the experience of growing older. We’ve all had this experience. And you could just look at him as an average person and say, ‘This guy is deteriorating very quickly.'”

He added: “I don’t know, I mean, but it’s obvious. I mean, Alex Jones sees it, you see, he can see it all the way to the right. I have Megyn Kelly and Tucker [Carlson] fighting with Mark Levin. I can’t even keep track of them all. They hate each other when they hate us.”
