According to a professional clinical psychologist, Donald Trump‘s cognitive health is declining at a rapid pace. Dr. John Gartner, a clinical psychologist and former assistant professor at Johns Hopkins University School of Medicine, revealed his observations on The Daily Beast podcast.

He said, “Look at Donald Trump today, because that’s the best Donald Trump you’re ever gonna see. It only goes downhill from here.” According to Gartner, Trump, who recently turned 80, has apparently shown signs of “Frontotemporal Dementia” (FTD) since “2019.”

FTD is a brain disease that causes the frontal and temporal lobes to shrink, leading to drastic changes in a person’s behavior, personality, or ability to speak. While it spares a person’s memory initially, unlike Alzheimer’s, it strikes much earlier in life, typically targeting individuals between 40 and 65, and fundamentally altering who they are.

Gartner noted in a recent podcast episode, “Your judgment is poor, your impulse control is poor, and eventually it starts to, if someone has dementia, it starts to accelerate their cognitive decline further.” He referred to Trump’s sleeping patterns, where he sleeps during public appearances and stays awake at night, often posting on Truth Social.

Trump was captured dozing off at the NBA finals. Sportscaster Stephen A. Smith said about Trump, “I’m not going to accuse him of snoring, because I wasn’t in earshot, but the brother wasn’t awake.”

Gartner listed several stressors affecting Trump. These included the Iran war, the abandoned billion-dollar anti-weaponization fund, and the rejection of the Kennedy Center name. He said, “This really is a perfect storm. Absolutely, it also contributes to mental health problems and dementia.”

The war with Iran, which was supposed to last four weeks, crossed the three-month mark without a peace deal. Meanwhile, Trump keeps bragging about being in good shape and acing his health checkups. He wrote on Truth Social, “I scored a perfect 30 out of 30.”

The 80-year-old’s personal doctor wrote, “remains in excellent health, demonstrating strong cardiac, pulmonary, neurological, and overall physical function.” On the other hand, Gartner pointed out, “This is the sickest individual I’ve ever encountered in my career—and sickest in the worst way.” He further added, “He’s so many standard deviations away from what we would normally consider normal, and that it’s coming to a head now is in his fantasies of being this military conqueror.”

The expert also mentioned how the 80-year-old is using his social media posts to groom the public. In one of his posts, he wrote, “He who saves his country does not violate any law.” Gartner said, “What I believe, [is that] he is setting us up. He is grooming us for nuclear war.” The clinical psychologist also revealed another concern. He said it may be tied to Trump’s polling numbers, which are worse than ever.
