Former President Donald Trump’s aspirations for a third term have reignited not just legal debates—but also concerns over his cognitive and physical decline, according to analysts. Bloomberg Opinion’s Timothy L. O’Brien, a longtime Trump biographer, said during an MSNBC appearance that Trump is “haunted” by fears of suffering from the same cognitive deterioration that affected his father, Fred Trump Sr., who battled Alzheimer’s for nearly a decade before his death in 1999.
O’Brien pointed out noticeable signs of aging in Trump, who turns 79 in June, noting a stark contrast to his earlier years in office. “The speech is more slurred, the posture is slouched, the energy seems drained,” O’Brien observed, adding that Trump’s pursuit of power may now be driven more by fear—of fading influence or legal consequences—than political ambition. “He’d probably like to be president for 200 years,” O’Brien joked, “but aging is catching up to him.”
The anxiety over cognitive decline is especially striking given Trump’s frequent criticism of President Biden’s mental fitness. Yet, O’Brien and others argue that Trump’s own behaviors—rambling speeches, physical lethargy, and momentary confusion—have become difficult to ignore. Even Trump’s nephew, Fred C. Trump III, has expressed concerns, comparing the former president’s recent changes to those of Fred Sr., calling them “eerily familiar.”
As Trump toys with the idea of extending his political career beyond two terms—despite clear constitutional limits—his health and legacy loom large. While the prospect of a third run remains uncertain, experts say the focus on his mental and physical decline could become a defining factor, forcing voters and allies alike to consider not just Trump’s politics, but his vulnerability to time.
