Donald Trump is reportedly gripped by a long-standing fear that he could suffer the same fate as his father, Fred Trump, who battled Alzheimer’s disease before his death in 1999. The revelation came during a recent episode of MSNBC’s The Weekend: Primetime, where journalist and longtime Trump observer Timothy L. O’Brien offered a psychological profile of the former president’s motivations and mindset as he eyes a possible political return.
At 78, with a 79th birthday approaching in June, Trump continues to flirt with the idea of a third presidential term, even though such a move is explicitly prohibited by the 22nd Amendment. But O’Brien argues that beyond constitutional limits or electoral strategy, Trump’s greatest obstacle may be more personal: his health.
“He lives in fear of following the same path his father did, from dementia to Alzheimer’s,” O’Brien said, noting that it’s a burden the former president has carried quietly for years.
Fred Trump, a powerful and influential New York real estate developer, began exhibiting symptoms of cognitive decline in the early 1990s. He was officially diagnosed with Alzheimer’s in 1991 but remained active in his business well into his decline. “He came into the office every day until the day he went to the hospital,” recalled family friend Richard Levy.
According to O’Brien, Donald Trump rarely discusses his father’s illness publicly, largely due to the political risks it carries. As a public figure who often mocks the perceived mental sharpness of rivals—especially President Joe Biden—Trump has avoided making any admissions that might be interpreted as vulnerability.
But observers close to him, including family members, have noted a shift.
“Compare him now to Trump 1.0,” O’Brien said. “The speech is more slurred, the posture is slouched, the energy seems drained. I question how much genuine enthusiasm he has left for the job, beyond the fact that it keeps him out of prison and in the spotlight.”
Trump’s nephew, Fred C. Trump III, reinforced these concerns in a People magazine interview last year, saying he’s seen echoes of his grandfather’s decline in his uncle. “Like anyone else, I’ve noticed the shift,” said Fred, 61. “And I see it unfolding in a way that’s very similar to how my grandfather declined. Anyone claiming dementia isn’t in the Trump family is ignoring the truth.”
For O’Brien, Trump’s ongoing obsession with maintaining relevance and control—through media appearances, campaign rallies, and legal maneuvering—is rooted in a deeper fear of becoming irrelevant or diminished. “He’d love to live until he’s 300,” O’Brien joked. “And he’d probably like to be president for 200 of those years.”
But the reality of aging is catching up.
While Trump continues to tease his supporters with suggestions of defying term limits, O’Brien believes he’s unlikely to attempt a third term outright. Still, the analysis paints a picture of a man driven less by ideology or policy and more by personal survival—physical, political, and legal.
Whether Trump acknowledges his fears publicly or not, those closest to him—and a growing number of analysts—believe they play a powerful role behind the scenes. As Trump battles multiple indictments, civil cases, and the relentless spotlight of national politics, the shadow of his father’s legacy looms ever larger.
