Donald Trump is reportedly troubled by the possibility of facing the same cognitive decline that affected his father, according to analysis shared on MSNBC’s The Weekend: Primetime.

Timothy L. O’Brien, senior executive editor at Bloomberg Opinion, discussed Trump’s recent comments about wanting a third presidential term—something barred by the Constitution. O’Brien suggested Trump is driven by “self-aggrandizement” or “self-preservation,” and while he may fantasize about extended power, O’Brien doubts he’ll actively pursue a third term.

“He’d love to live until he’s 300,” O’Brien joked, “and be president for 200 of those years.” But at 78, Trump isn’t immune to aging. “What struck me was how much he’s aged. His speech is more slurred, posture more slouched, energy drained,” O’Brien said, noting Trump turns 79 in June.

A key concern, O’Brien noted, is Trump’s fear of mental decline. His father, Fred Trump, was diagnosed with dementia in 1991 and died in 1999 after battling Alzheimer’s. Trump has rarely addressed this publicly, likely due to political risk, especially after mocking President Biden’s mental fitness.

Those close to Trump have reportedly noticed changes. “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,” O’Brien added.

Trump’s nephew, Fred C. Trump III, echoed these concerns in People, saying he sees familiar signs of decline. “Anyone claiming dementia isn’t in the Trump family is ignoring the truth,” he said.
