The Trump family already knows how to manage cognitive decline. They’ve done it before.
If you think Donald Trump has dementia, you’re probably right.
The Trump family has been here before. They know exactly what cognitive decline looks like. And they know exactly what to do about it.
According to The New World, Fred Trump Sr. spent the last years of his life showing up to an office where the paperwork was blank, the phone was disconnected, and the secretary out front was in on the con. His children created an elaborate theatrical production - a Potemkin office - so the old man could shuffle papers and feel important while they quietly drained his real estate empire - by one estimate worth close to a billion dollars - into their own pockets.
Every morning, Fred Sr. got dressed in his three-piece suit. His chauffeur drove him to Brooklyn. He sat at the same desk he’d occupied for fifty years. He signed documents. He picked up the phone. He thought he was running the company.
But the documents were meaningless. The phone only connected to a secretary in the lobby who was in on the plan. The way The New World tells it, the whole thing was a stage set designed to manage an elderly man with Alzheimer’s who refused to give up control of his company.
I’m sure that’s not relevant to anything happening right now.
Here’s what we know from court records and family testimony: Fred Trump was diagnosed with “mild senile dementia” in October 1991. By 1992, doctors reported he couldn’t remember his own birthday, didn’t know his age, and scored below the 15th percentile for cognitive function in his age group. After a thirty-minute delay, his ability to recall anything he’d just been told was - and I’m quoting the medical report here - “nil.”
His grandson Fred III told People magazine that the old man would get out of his limousine at traffic lights and just start walking away. He’d scream at his wife over nothing. A family friend told Vanity Fair he once came downstairs wearing three ties. At Donald’s 1993 wedding, Fred Sr. had to be reminded why he was there - despite being designated the best man.
And through all of it, they kept bringing him to the office. Kept him in the routine. Because familiarity kept him calm. Agitation and outbursts were the alternative.
Here’s where it gets darker.
Back in December 1990, as Fred Sr.’s mind was starting to slip, Donald was busy getting his father’s lawyer and accountant to draft a codicil that would have given him complete control of the estate. According to Mary Trump - Fred’s granddaughter - the plan was to slide it in front of the old man “as if it had been Fred’s idea all along.”
But Fred had a lucid day. He knew something was wrong. He called his daughter Maryanne, who showed it to her lawyer husband. His response, according to secretly recorded conversations Mary later released: “Holy shit.” Then Maryanne, on the same tapes: “It was basically taking the whole estate and giving it to Donald.”
The codicil didn’t get signed. But within a few years, with Robert Trump holding power of attorney, the siblings transferred the vast majority of their father’s empire to themselves anyway. When Fred Sr. died in 1999, he had less than $2 million in the bank. Five years later, his kids sold the company for $700 million.
So the Trump children have experience with this.
They know how to manage a cognitively declining patriarch. They know how to keep him comfortable and feeling important. They know how to maintain the illusion of control while the real decisions happen elsewhere. They know how to extract value from a situation while protecting the principal from anything that might upset him.
Fast forward to January 2026.
Donald Trump is 79 years old - the oldest person ever inaugurated as president. His father was diagnosed with dementia at 85. According to Fred III, his sister Maryanne showed signs of dementia before she died, though she was never diagnosed, and his cousin John Walter had it too. “If anyone wants to believe that dementia did not run in the Trump family, it’s just not true,” Fred III told People.
In December, Trump appeared to fall asleep on camera during his own Cabinet meeting. Not once. Not twice. The Washington Post counted nine separate instances over a 75-minute stretch where his eyes closed for extended periods or he seemed to struggle to keep them open - nearly six minutes total - including while Marco Rubio spoke directly next to him. His head dropped. He snapped back awake. This was on live television.
A New York Times investigation found Trump has cut his official appearances by 39 percent compared to his first term. His public events now typically start after noon instead of 10:30 a.m. He’s reportedly asking staff to put “fewer, more important meetings” on his schedule. He posted in December that it’s “seditious, perhaps even treasonous” for The New York Times “and others” to run what he called “FAKE reports” about his health.
And here’s the thing that should make everyone’s hair stand up: Trump keeps bragging about “acing” cognitive tests. Three of them now. Dr. John Gartner, a psychologist who’s been tracking this, put it simply: “You could maybe justify giving someone the MoCA once, just on their age. If you’re giving it to him three times, that means you’re not assessing dementia. That means you’re monitoring dementia.”
Mary Trump, the clinical psychologist niece, says she sees the same “deer in the headlights” look in her uncle that she saw in her grandfather during his decline. Fred III says he watches his uncle’s deterioration “in parallel with the way my grandfather’s decline was.”
And who’s surrounding him? JD Vance. Stephen Miller. Marco Rubio. A rotating cast of ideologues and opportunists who figured out what the Trump children figured out thirty years ago: you can get a lot done when the guy at the top thinks he’s still in charge.
The paperwork Fred Sr. shuffled was blank. The phone went nowhere. But he felt like he was running things.
Trump’s schedule is lighter. His meetings are shorter. His public appearances start later. The executive orders keep flowing - 228 of them and counting - written by people who aren’t Trump. And somehow, mysteriously, the people around him keep getting exactly what they want.
Half of Americans now say they believe the president is suffering cognitive decline. But the White House won’t answer basic questions about when his cognitive tests were taken. Press Secretary Karoline Leavitt promised details “at a later date.” That date hasn’t come.
The Trump family built a Potemkin office for Fred Sr. because they understood something fundamental: you can control an empire if you can control what the man at the top sees, hears, and believes.
The only difference now is the office is oval, the paperwork isn’t blank, and the stakes are global.

Correction, September 28th, 2026: This essay first called Maryanne Trump Barry Donald’s aunt and said she had dementia - she was his sister, and Fred III says she showed signs of it but was never diagnosed. It said Trump posted that it’s treason for anyone to discuss his health - he aimed that at The New York Times and others running what he called fake reports. It put Maryanne’s own words from the tapes in her husband’s mouth, said Fred Sr. was diagnosed at 86 (he was 85), spelled his cousin’s name John Walters (it’s John Walter), said the lobby secretary was paid to play along (the account says she was in on the plan), said the paperwork he signed was blank (it was the paperwork he shuffled), placed the December 1990 push to change his will during the blank-office years (it came first), and said Fred III wrote about the limousine (he told People). It also quoted Fred III saying “It runs in the family” - that line isn’t in his People interview, so it’s gone; his real quote stays.
Update, September 28th, 2026: A few lines now say who says so - the blank-office story is The New World’s reporting, the three-ties story is a family friend’s, and Fred III has also said the office routine gave his grandmother a rest - and the Cabinet meeting lines now say Trump appeared to doze, which a White House official denied.
