Donald Trump suffered a stroke several months ago and has kept it from the public, a prominent medical expert has suggested.

Professor Bruce Davidson of Washington State University’s Elson S. Floyd College of Medicine made the bombshell claim about the 79-year-old president’s health while laying out “lines of evidence supportive” that have also been reported on by the Daily Beast over the past year.

“I think his stroke was on the left side of the brain, which controls the right side of the body,” Davidson told biographer Sidney Blumenthal and Princeton historian Sean Wilentz on their podcast, The Court of History.

“I think the stroke was six months ago or more, earlier in 2025,” he continued. “There are videos of him shuffling his feet, which is not what we’d seen previously when he was striding on the golf course. We’ve seen him holding his right hand cradled in his left. Earlier in 2025, he was garbling words, which he hadn’t done before and which he’s improved upon more recently.”

Davidson also pointed to what he described as “marked episodes of excessive daytime sleepiness,” known medically as hypersomnolence, which he said is common among stroke patients. Trump is now routinely appearing to nod off in public appearances such as White House events.

He further suggested that footage showing Trump gingerly descending the steps of Air Force One while gripping the banister with his left hand, despite the president being right-handed, is “consistent with having had a stroke on the left side of the brain.”
