As Donald Trump continues to post in rapid bursts late into the night, a medical term tied to Alzheimer’s – “sundowning”– has increasingly entered the conversation.
Well past midnight, when most of the world has gone quiet, Donald Trump’s social media feed often does the opposite.
Posts appear in rapid bursts, sometimes dozens within minutes, then silence, then more again before sunrise. The pattern has become so familiar that it no longer surprises regular observers, yet it continues to raise the same question each time it happens: what exactly is driving it?
In that conversation, one term keeps resurfacing – “sundowning.” It is used frequently, often casually, and sometimes pointedly, but the meaning behind it is far more specific than the way it is being thrown around.
The renewed focus on the president’s posting habits comes from a series of intense overnight stretches that have drawn attention far beyond his usual audience.
According to a report by The Daily Beast, one recent “fit of rage” saw Trump publish 48 posts within 36 minutes, then return again at 6:00 a.m.
Donald Trump’s late-night activity
Another stretch saw him post 19 times over a 12-hour window, including 10 in just 20 minutes around midnight. The content has ranged from criticism of political figures like Gavin Newsom and NATO to the sharing of AI-generated images and disputed policy claims.
The pace, combined with the timing, has led critics to question whether the behavior reflects more than simply a preference for working late.
Trump has long said he’s not much of a sleeper, and in an interview with The Guardian, his biographer said, “He has made a big deal of saying he never sleeps and people who sleep are lazy.”
Despite how often the term appears in commentary, sundowning is not a general description for late-night activity or erratic behavior. It is a recognized medical phenomenon tied to cognitive conditions.
What is sundowning?
The Alzheimer’s Association explains that sundowning refers to a group of symptoms that can affect people living with Alzheimer’s disease or other forms of dementia, typically appearing in the late afternoon and continuing into the evening and night.
It is not a condition on its own, but rather a pattern that can emerge as part of cognitive decline.
Common symptoms include:
- Increased confusion and disorientation
- Anxiety and agitation
- Mood changes or irritability
- Verbal or physical aggression
- Pacing or wandering
- Trouble sleeping
- Hallucinations or delusions in more advanced stages
According to the Alzheimer’s Association, as many as two in three people with Alzheimer’s may experience these symptoms at some point, most often in the middle or later stages of the illness.
Applying that framework to Trump makes the conversation far more complicated.
Better than a ‘normal mortal’
There has been no confirmed diagnosis of Alzheimer’s disease or dementia, and his most recent medical evaluation described him as being in “excellent health.” According to NBC News, Trump also claimed he scored perfectly on the Montreal Cognitive Assessment, a screening tool used to detect early signs of cognitive impairment.
The White House has dismissed suggestions of any underlying issue, with Deputy Chief of Staff Stephen Miller saying Trump “can work harder, has a better memory, more stamina and energy than a normal mortal.”
Medical professionals caution against drawing conclusions from isolated behaviors. Geriatric psychiatrist Dr. Ryan Hall told the International Business Times (IBT) that sundowning “is something caregivers notice over time, not something you diagnose from a single behaviour or a single evening.”
That distinction is important, especially in a discussion that often blends observation with assumption.
But in Trump’s case, the conversation rarely stays confined to medical nuance for long.
Term shaped by politics
The reason sundowning keeps appearing in headlines and commentary is closely tied to the political climate surrounding Trump.
That political tension often plays out in real time, especially following some of Trump’s more controversial posts.
After Trump wrote on Truth Social on April 7 that “A whole civilization will die tonight, never to be brought back again,” the reaction was swift, with Senate Majority Leader Chuck Schumer calling him “an extremely sick person,” while Representative Ted Lieu said, “What the president is doing is batshit crazy.”
At the same time, the New York Times reports that congressman Jamie Raskin called for a comprehensive cognitive evaluation, citing what he described as “increasingly incoherent, volatile, profane, deranged, and threatening” statements.
As the debate continues, it leaves a lingering question – do you believe Donald Trump is as healthy as he suggests? Please let us know your thoughts and then share this story so we can hear what others have to say!
