By 2021 and 2022, Peterson was back online, giving interviews, releasing books, launching new media ventures. But something seemed different. His tears during interviews, the canceled engagements, and the occasional look that implied tiredness were all signs of a rawer, more emotionally unstable version that many who followed him closely witnessed. His daughter later said much of this was pain. Not metaphorical pain. Literal, physical pain from a condition the family says they didn’t yet have a name for.
That name arrived in 2018, at least retroactively Chronic Inflammatory Response Syndrome, or CIRS. It’s a contested diagnosis attributed to prolonged exposure to biotoxins, particularly mold in water damaged buildings. Proponents say it triggers a cascading immune dysfunction in genetically susceptible individuals. The Centers for Disease Control and Prevention does not list it as a recognized health effect of mold. Australia’s government conducted a formal inquiry and concluded the medical evidence remains insufficient.

Most mainstream physicians either haven’t heard of it or regard it with scepticism. Peterson and his daughter see this differently. Mikhaila Fuller has called the medical community’s lack of recognition absurd, predicting CIRS will be commonly diagnosed within the next decade. There’s a familiar pattern here the Petersons have long positioned themselves on the forward edge of medical self advocacy, sometimes persuasively, sometimes in ways that invite sharp criticism.
The crisis accelerated in the summer of 2025. Peterson had been helping clean out his late father’s house a task most people would consider mundane, maybe emotionally difficult but physically harmless. His daughter claims that mold had a serious impact on the basement. His symptoms worsened in a few of weeks.
Mikhaila declared on X in August that her father would no longer be participating in the podcast, the European tour, or public appearances. Over the last year or so, he’s been feeling the impact of CIRS more and more, she said. Then things worsened. Pneumonia struck. Sepsis ensued. In what Mikhaila called a near death situation, Peterson was in an intensive care unit by September and had been unable to interact with his family for weeks. He spent over a month there.
The complex web of medical truths and disputed frameworks surrounding it is what makes the entire story so challenging to understand. According to his daughter, Peterson is unable to take the majority of drugs without experiencing extreme paradoxical effects. Nutritionists and gastroenterologists are perplexed by his years long diet of only beef, salt, and water, which he and Mikhaila claim helped with some symptoms.
And then there’s the spiritual dimension Mikhail, who became a Christian in 2024, has openly speculated that her family is under some form of spiritual attack, pointing to a sequence of emergencies her father’s hospitalization and her infant daughter’s near fatal heart failure happening within hours of each other as evidence of something beyond medical explanation. It’s the kind of thing that makes people laugh on the internet, and many people did. But it also reflects the very real desperation of a family watching its patriarch deteriorate without a clean diagnosis or a straightforward treatment.
By December 2025, Peterson was discharged from the hospital and returned home to Arizona. Reports indicated additional surgery and post procedure delirium. Mikhail’s updates grew more cautious, more measured fewer details, a tone that suggested she was bracing for a long road.
She told followers her father was improving day by day but that the timeline for full recovery remained unknown. She talked about the modest domestic scene that had surprising weight watching Peterson Academy courses together. It’s possible the man who once lectured to sold out arenas is now watching lectures from a chair in his living room.
The medical establishment’s response to CIRS remains largely unchanged. No major public health agency has formally recognised it. The body of peer reviewed evidence is minimal. Dr. Ritchie Shoemaker, who coined the term in the 1990s and appeared on Peterson’s podcast, advocates treatment involving elimination of biotoxin exposure and immune system support, but his approach sits well outside mainstream clinical practice.
For Peterson’s critics, the whole episode confirms suspicions about a man they see as peddling pseudo intellectual ideas, now entangled with fringe medicine. For his supporters, it validates a narrative of institutional failure the same medical system that, they argue, mishandled his benzodiazepine withdrawal is now ignoring a legitimate condition. Both sides appear to be very assured. It’s likely that neither would acknowledge how messy the reality is.
What’s clear is that Peterson’s public life has been profoundly diminished. The podcast has been put on hold. The tours have been canceled. In his absence, his daughter and coworkers are running his academy and brand. Ben Shapiro and other conservatives have openly wished him luck.
In the meantime, the internet continues to function as it always does, with some users praying and others making fun of the algorithm. There’s a sense that Peterson’s story has grown beyond a single man’s medical file as you watch this develop over time. It’s a case study of how disease, celebrity, and disputed science collide and how the solutions we seek are rarely.
