Age and health concerns about Donald Trump

At 78 years, 4 months and 22 days of age, Donald Trump is the oldest major-party presidential nominee in history, after President Joe Biden withdrew from contention prior to becoming the nominee of his own party in the 2024 United States presidential election. If elected, by the end of his term he would become the oldest person ever to hold the office, sparking renewed discussion of his fitness to assume the presidency. Since the early days of Trump's 2016 presidential campaign, his physical and mental health have been a subject of public debate. Trump was 70 years old when he first took office, surpassing Ronald Reagan as the oldest person to assume the presidency to that date. During Trump's presidency, comments on his age, weight, lifestyle, and history of heart disease raised questions about his physical health. In addition, numerous public figures, media sources, and mental health professionals have speculated that Trump may have mental health impairments, ranging from narcissistic personality disorder to some form of dementia, which runs in his family.
