A case study for you.
Over the coming months, Lang watched with concern as the purported cluster ballooned in New Brunswick. He emailed Marrero and left messages with his secretary offering help, but never heard back. In late 2023, frustrated by what he saw as cluster misinformation everywhere, Lang decided with colleagues to mount a study. The results — published in May 2025 in the Journal of the American Medical Association, JAMA — landed in New Brunswick like a hand grenade.
Lang and his co-authors — including several former Mind Clinic colleagues of Marrero and the concerned neuropathologist, Gerard Jansen — found that all 25 patients in their study had suffered from previously known conditions, from functional neurological disorder to dementia to cancer. The probability of there being no new disease was close to 100%, they said. The real cause of the cluster, they concluded, was serial misdiagnosis by Marrero, compounded by credulous media reporting, the limitations of New Brunswick's public health system, institutional distrust sown by the pandemic and the actions of a small group of people "co-opting the crisis to suit their agenda".
And
An upcoming provincial report could offer some answers. Unlike the previous studies, it will examine the claims of elevated glyphosate and heavy metals in the patients. At times, the stakes seem impossibly high. "Lives hang in the balance," read a recent letter to Premier Susan Holt, signed by 72 of the patients. "It is within your power to honour them, cherish them, and care for them," the letter said. "Or you can abandon them and let them wither, fade, and ultimately die. Please join us on the right side of history."
The patient advocates, led by Bloodwatch director Kat Lanteigne, have arguably done more than anyone to keep the story of the cluster going, with an operation that includes lobbying the government, briefing the press and sending legal letters to scientists.
Lanteigne has publicly attacked both Jansen and Lang over the JAMA study, branding their work inaccurate and unethical. She denied harassing Jansen, saying she had never spoken to him directly and emailed him only once. "I have a record of speaking truth to power and I have always worked with integrity and honesty," she said.
Both Lang and Jansen are standing their ground.
"What we have here is a case of misdiagnosis, evolving to misinformation, and sadly resulting in suffering for patients and families," Lang said.
"I would even go further," Jansen said, regarding the alleged misdiagnosis of the patients. "I would say they are being abused."
Now maybe they WILL find evidence to demonstrate there is an environmental issue here. But it's a bit weird it's only patients of one doctor that seem to be affected and they've become self selecting.
There's many parallels here that are slightly unnerving as you read through the actual.
