Donald Trump's mental fitness has been thrust back into the spotlight after psychologist Dr. John Gartner claimed the US President is 'mentally ill and cognitively deteriorating' and suggested his behaviour shows signs of either mania or sundowning. Speaking on The Daily Beast Podcast, the former Johns Hopkins University professor argued that Trump's age, restless posting habits and increasingly unusual online content point to what he sees as a serious decline.
Gartner's comments come as Trump approaches 80 and continues to dominate headlines with an unrelenting stream of social media activity. The psychologist rejected the idea that public figures cannot be judged from afar, insisting the pattern is obvious enough for ordinary observers to recognise. In his view, the issue is not whether Trump has been formally examined, but whether his public behaviour has become too erratic to ignore.
