Jordan Peterson is taking time off after being diagnosed with chronic inflammatory response syndrome (CIRS), his daughter Mikhaila Fuller announced on Aug. 13. Fuller described the diagnosis as an immune-system dysfunction triggered by exposure to mold and other contaminants in indoor air, saying the condition has helped explain years of health issues for her father.
CIRS, as defined by the National Institutes of Health, is an acquired condition characterized by innate immune dysregulation following exposure to water-damaged buildings. It can affect multiple organ systems and present a wide range of symptoms.
Fuller attributed Peterson’s health challenges to a genetic predisposition, noting that about 25% of people carry this predisposition, though his case is described as severe. She said the diagnosis came after a recent exposure to a moldy environment while helping clean out her grandfather’s house following his passing, which she said severely flared his symptoms.
She emphasized that the issue is an immune-system dysfunction rather than akathisia or a medication side effect, and she clarified that Peterson is not currently on any medication. Fuller connected CIRS to several allergic reactions and food sensitivities Peterson has experienced over the years, suggesting symptoms have intensified since 2017.
As a result, Peterson has had to cancel events and pause his podcast. Fuller expressed cautious optimism, stating that there is treatment available and that he is responding, albeit with a difficult recovery process. She also thanked God for finally gaining clarity on what has been impacting her father.
Peterson, a Canadian-born psychologist, conservative commentator, author, and podcaster, has long engaged with a broad audience. Although he does not identify as Christian, he has hosted conversations with Christian figures and figures of faith, underscoring a history of dialogue across beliefs.
Fuller also co-founded Peterson Academy in 2024, serving as the online education platform’s CEO, a venture she described as part of her father’s broader work.
Outlook and context
– The family says progress is possible, with treatment and time as key factors in recovery.
– Medical experts generally emphasize thorough evaluation for environmental exposures and symptom clusters when diagnosing CIRS, and treatment plans can vary depending on individual circumstances.
– Followers and supporters of Peterson will likely be watching for updates on his health and any return-to-work timeline as his team navigates the next steps in care.
Summary: Peterson has been diagnosed with CIRS and will pause professional activities while pursuing treatment, with his daughter outlining a genetic predisposition and a mold-related trigger. The family remains hopeful about a steady path to recovery, acknowledging the health challenges while highlighting support and treatment options.
Additional note
– This development may renew conversations about environmental health and the ways chronic conditions linked to indoor air quality are understood and managed. If you’re following Peterson’s work, expect further updates from his team as recovery progresses.
