CJD is each deadly and probably contagious, so a gaggle of consultants was rapidly assembled to research. Thankfully for New Brunswick, the illness did not unfold. However the story did not finish there. In reality, it was simply starting.

Among the many consultants was Alier Marrero, a soft-spoken, Cuban-born neurologist who had been working within the province for about six years. Marrero would share some worrying info with the opposite members of the group. He had been seeing sufferers with unexplained CJD-like signs for a number of years, he mentioned, together with younger individuals who confirmed indicators of a quickly progressing dementia. The variety of circumstances was already greater than 20, Marrero mentioned, and a number of other sufferers had already died.

Due to the obvious similarity to CJD, Marrero had been reporting these circumstances to Canada's Creutzfeldt-Jakob Illness Surveillance System, or CJDSS. However the outcomes had been coming again destructive. Marrero was stumped.

Extra worrying nonetheless, he was seeing a dizzying array of signs among the many sufferers, based on his notes. There have been circumstances of dementia, weight reduction, unsteadiness, jerking actions and facial twitches. There have been sufferers with spasms, visions, limb ache, muscle atrophy, dry pores and skin and hair loss. Many mentioned they have been struggling with each insomnia and waking hallucinations. Sufferers reported extreme sweating and extreme drooling. A number of exhibited Capgras Delusion, which causes somebody to consider that an individual near them has been changed by an identical-looking imposter. Others appeared to lose the flexibility to talk. One affected person would report that she had forgotten write the letter Q.

Marrero ordered check after check. However he was at a loss. "I simply saved seeing new sufferers, I saved documenting new circumstances, and I saved seeing new individuals dying," he recalled. "And a picture of a cluster grew to become extra clear."

Over the approaching months, Marrero and the CJDSS scientists started to suspect that as a substitute of a small cluster of CJD sufferers, the province of New Brunswick might need on its palms a a lot bigger cluster of individuals affected by a totally unknown mind illness.

Over the following 5 years, Marrero's cluster would balloon from 20 to an astonishing 500. However there got here no scientific breakthrough, no new understanding of neurology, no costly new therapies. As a substitute, final 12 months, a bombshell analysis paper authored by a number of Canadian neurologists and neuroscientists concluded that there was actually no thriller illness, and that the sufferers had all seemingly suffered from beforehand recognized neurological, medical, or psychiatric situations. The New Brunswick cluster was, one of many paper's authors informed the BBC, a "home of playing cards".

To report this story, the BBC hung out with Marrero and spoke to a dozen of his sufferers or their family members — a few of whom are telling their story for the primary time — in addition to key scientists, consultants, and authorities officers, and reviewed tons of of pages of inside emails and paperwork obtained by freedom of knowledge requests.

We will reveal that at the very least one cluster affected person has now opted for demise through medical help in dying — authorized in Canada since 2016. The analysis on the demise certificates, based on the physician who signed it off, was "degenerative neurological situation of unknown trigger". At the very least one different cluster affected person is at the moment contemplating assisted dying.

The analysis paper revealed final 12 months may have marked the tip of a wierd chapter in Canadian science. Besides, tons of of the sufferers disagree. Defiant, fiercely loyal to Marrero, and backed by passionate affected person advocates, they argue that the paper is flawed and reject any notion that the cluster may not be actual.

Many consider as a substitute that they've been poisoned by an industrial environmental toxin, and that the federal government of New Brunswick has conspired in opposition to them to cowl it up.

"I am not a conspiracy theorist kind particular person, in any respect, however I actually assume it is financially motivated," mentioned Jillian Lucas, one of many sufferers. "There's all these totally different ranges."

He was referred to Marrero, who ordered a battery of assessments however was unable to elucidate his signs. Cuthbertson grew to become one of many early cluster sufferers — the so-called "unique 48".

Lucas had simply gone by means of a divorce and suffered a nasty concussion, and he or she moved again in together with her mom and Cuthbertson of their rural group close to town of Moncton. Quickly she started experiencing her personal signs and went to see Marrero for herself.

"He ran so many assessments, a lot blood work and scans and spinal faucets," Lucas recalled. "We have been making an attempt to rule completely every part out and we simply saved developing with extra questions."

Quick on solutions, Marrero added Lucas to the cluster. Over the approaching months, her signs worsened and new signs appeared. She skilled gentle sensitivity, tremors, horrible migraines and points together with her reminiscence and skill to talk clearly, she mentioned. She felt unexplained stabbing pains. Chilly water felt scalding scorching.

Marrero, although, was attentive and caring. He took her signs severely. "He made me really feel seen and that what I used to be experiencing was essential," Lucas wrote in a Fb submit about her wrestle.

It was a sentiment that gave the impression to be shared by everybody who noticed Marrero. He held their palms throughout appointments. He remembered them, cried with them. He was "the one one listening to them," mentioned Lori-Ann Roness, one of many cluster sufferers.

"He is an unimaginable human and doctor," mentioned Melissa Nicholson, whose mom died final 12 months after being identified with the thriller illness.

"Watching our mother undergo it was exhausting sufficient," Nicholson mentioned. "However he was such a pillar of help."

In March 2021, with Canada nonetheless within the grip of the Covid pandemic, the cluster out of the blue grew to become information. New Brunswick's chief medical officer had despatched a memo to medical doctors alerting them to the obvious syndrome and suggesting they contact Marrero with potential circumstances. The memo leaked and the story hit the papers.

Marrero discovered himself inundated with new sufferers. However he was additionally drawing help from the very best ranges of Canadian science. The working group arrange to reply to the unique CJD circumstances had advanced right into a multi-disciplinary group finding out the cluster, and the potential for a mysterious new neurological situation appeared, at occasions, irresistible to the scientists.

"It is like studying a film script," emailed one researcher to colleagues, about an early story within the Toronto Star.

"We're all within the film!", a senior federal scientist replied.

On the coronary heart of the working group was Marrero, together with Dr Michael Coulthart, the pinnacle of the CJD Surveillance System; Dr Neil Cashman, a number one Canadian neurologist; Dr Michael Sturdy, the pinnacle of the Canadian Institutes of Well being Analysis (CIHR); and Dr Samuel Weiss, one of many CIHR's senior neurologists. All agreed that Marrero wanted appreciable help. Sturdy mentioned he may organize extra employees and supplied himself up as a advisor. The CIHR supplied the province of New Brunswick C$5 million ($3.6m; £2.7m) to research.

And the thriller illness obtained a reputation: the "New Brunswick Neurological Syndrome of Unknown Trigger". In an e mail to Marrero in April 2021, Sturdy known as it "probably the most uncommon constellations of findings I've ever seen".

"All of us owe you a debt of gratitude," he wrote.

However not everybody was on board. Dr Gerard Jansen, a neuropathologist who was connected to the CJD Surveillance System, had observed one thing uncommon when referrals from Marrero's workplace began piling up. Jansen recalled feeling "flabbergasted" at Marrero's notes, which he mentioned featured an array of broad and unrelated scientific observations — a "diarrhea of signs".

Jansen noticed clues within the sufferers' recordsdata that he mentioned pointed to already outlined neurological illnesses. When he examined mind tissue samples of some cluster sufferers who had died, he discovered indicators of Alzheimer's illness and Lewy physique dementia.

He was alarmed. His superior, Coulthart, appeared to consider one thing unexplained was occurring in New Brunswick, Jansen mentioned. Eager to get his issues down in writing, he despatched Coulthart a protracted and detailed e mail.

"All accessible proof and logic" pointed to a set of various illnesses, Jansen wrote.

"The sufferers are actual, however the clustering as a thriller illness just isn't."

Suspecting an environmental hyperlink, the scientists and officers thought-about varied potential culprits, from a uncommon moose-borne parasite to blue-green algae blooms to Agent Orange sprayed on the province within the Seventies. Nothing bore fruit.

Marrero mentioned he had noticed an uptick in circumstances in late summer time and early autumn — forestry spraying season — and he zeroed in on a controversial herbicide known as glyphosate. Power publicity to glyphosate, which is used extensively by New Brunswick's forestry trade, has been linked by some research to neuroinflammation and Parkinson's illness. (Forest NB, an trade physique, informed the BBC that glyphosate was utilized in compliance with rules and was "not anticipated to pose dangers" to human well being or the surroundings.)

Based on Marrero, lots of his sufferers have been displaying extremely elevated ranges of each glyphosate and varied heavy metals. Although when requested by the BBC what quantity of his 500 or so sufferers had regarding outcomes, he refused to say. "I do not wish to present precise numbers of something, however as an instance it is an uncommon quantity. Past 100."

Sturdy, the CIHR director, mentioned he thought a full "boots-on-the-ground" investigation was wanted. The identical month, a specialist clinic — the Thoughts Clinic — was arrange in New Brunswick with Marrero on the helm to deal with the cluster sufferers. With the $5m on supply from the CIHR, and the backing of Sturdy and different high federal scientists, all of the situations appeared set to unravel the thriller.

However then, every part modified. In Might, New Brunswick successfully suspended the collaboration with the federal scientists. The province additionally determined to not take up the $5m on supply from the CIHR. Based on Marrero, the choice killed off any prospect of discovering a solution. "All people obtained that e mail like a chilly bathe," he mentioned.

Not one of the provincial officers concerned agreed to speak to the BBC on the document. However it's clear there was concern about Marrero's strategies and concerning the nature of his contact with Coulthart, Sturdy and the opposite federal scientists. The view of some at senior ranges of the New Brunswick authorities was that the casual working group, seduced by the potential for a scientific thriller, was circumventing the province.

However the determination to go away the cash on the desk, quite than spend it investigating, fuelled suspicions that New Brunswick needed to keep away from scrutiny of its surroundings. Based on Kat Lanteigne, the manager director of Canadian well being non-profit Bloodwatch and a tireless supporter of Marrero, the actions of the province amounted to a full-blown cowl up.

"They pulled the plug as a result of they simply don't need anyone trying," Lanteigne mentioned. "Full cease."

Jansen, the neuropathologist who had raised issues, had by that time examined the autopsies of eight cluster sufferers and firmly believed all of them had recognized, diagnosable sicknesses. Troubled, he handed his conclusions on to the oversight committee and offered them to the Canadian Affiliation of Neuropathologists.

Not lengthy after that, the New Brunswick authorities completed its investigations, concluding in February 2022 that there was no widespread environmental trigger and no widespread situation among the many sufferers. In different phrases, no thriller illness.

However the authorities had determined in opposition to inspecting any of the sufferers in particular person, an omission that outraged those that believed they have been a part of the cluster. The sufferers — now 105 in quantity — have been attending sporadic appointments with Marrero on the Thoughts Clinic however seeing little progress. Jillian Lucas's signs have been worsening at such a price that she had begun to weigh one thing as soon as unthinkable to her: medically assisted dying.

On the clinic, appointments with Marrero may very well be unusually conspiratorial, sufferers mentioned. Throughout one appointment, Lucas's stepmother Susan recalled, Marrero put his hand up, informed them to cease speaking, and went to the door to hear. "He mentioned, 'I consider we're being recorded'."

Stacie Quigley-Cormier, whose stepdaughter Gabrielle was the youngest member of the cluster, mentioned Marrero at all times spoke in a hushed tone.

"The expertise with Dr Marrero — and different sufferers discuss this too — is you be sure you begin speaking after the door is closed, and there is a quiet tone to his voice, and also you be sure you're not speaking within the hallways and issues like that."

Marrero declined to debate it. "Some sufferers truly thought that approach. And I… We puzzled… However I do not wish to remark."

In August 2022, Marrero was sacked from the Thoughts Clinic. "Regardless of our repeated makes an attempt to tell you of our expectations and the deficiencies in your efficiency, you haven't demonstrated a sustained capacity to fulfill our expectations," wrote John Dornan, then-CEO of the well being community. The 105 cluster sufferers every obtained their very own letter, telling them they might keep on the clinic, with all of the assets it needed to supply, or strike out alone with Marrero.

Many have been offended on behalf of their neurologist. "Once they known as me to ask my alternative, I mentioned, it is not a alternative, it is an ultimatum," Lucas mentioned. "And I select him."

She wasn't alone. Of the 105 sufferers, 94 selected Marrero. Simply 11 individuals determined to stick with the clinic and get a second opinion.

Exterior of the clinic, more and more remoted, Marrero continued to diagnose the thriller illness. He was sending sufferers for therefore many assessments, for such obscure toxins or situations, that some reported being met with an more and more quizzical eye on the testing clinic, as if to say, "What now?"

Others discovered it tough to get an appointment with Marrero and even communicate to his assistant.

April, then 60, had already been displaying some dementia-like signs, however the driving incident scared Strickland. Marrero ran a sequence of assessments on April and identified the thriller sickness.

"He informed me it was the thriller sickness and he needed to look additional into it, however he by no means actually did a lot after that," Strickland mentioned.

However to get her a spot in assisted residing he wanted a letter of help from Marrero. "I feel I waited 4 months for that letter," Strickland recalled. "I saved phoning and asking."

Ultimately he gave up and turned to the Thoughts Clinic, he mentioned, and obtained the letter. And the Thoughts Clinic neurologists gave April one thing else she wanted — a agency analysis. She was affected by a type of frontotemporal dementia. In the long run, Marrero "did nothing for April," Strickland mentioned. "I assume he was extra enthusiastic about proving the thriller sickness than he was serving to his sufferers," he mentioned.

Sandi Partridge additionally selected to stay with the Thoughts Clinic. She felt a deep sense of loyalty to Marrero, however she additionally noticed easy widespread sense in getting a second opinion.

Partridge had first seen Marrero in 2020, after struggling complications, hallucinations and seizures. He ordered a barrage of assessments — based on Partridge she had two MRIs, two EEGs, a SPECT, a CAT scan and a spinal faucet, in addition to greater than a dozen totally different antibody assessments. "It was principally a number of testing with Dr Marrero," she recalled. "Each time he would see me, it will be an hour and a half, typically two hours, and he would retest me each single time."

However each check got here again destructive. Partridge had additionally offered Marrero with a video of her having a seizure at residence, which he studied. He identified her with the thriller sickness. "These have been the phrases he used," she mentioned.

One factor Marrero by no means talked about to Partridge was useful neurological dysfunction, which was her eventual analysis. FND is a fancy situation; beforehand often known as psychosomatic or psychogenic sickness, it describes bodily signs that may have a psychological root - typically described as being a difficulty with the mind's 'software program' quite than any structural injury. It presents a problem to medical doctors, who need to information sufferers by means of the stigma related to it to an understanding that they've an actual situation that requires advanced remedy.

Partridge's neurologists on the Thoughts Clinic additionally reviewed the seizure video she had proven to Marrero, and noticed her having a seizure on the clinic. "As quickly as Dr Abdellah noticed my seizure he mentioned, that is FND," Partridge recalled. (Abdellah declined to talk to the BBC). Partridge threw herself into researching the situation. "And I assumed, that is me, that is me, that is me, that is me," she mentioned. "I hit each single marker."

Partridge remains to be struggling together with her situation, however she has obtained some remedy for FND and is pursuing extra. And her analysis introduced her some peace of thoughts. "The stigma is tough," she mentioned, "however I've accepted it."

Marrero was totally different — empathetic, caring. As he had with different sufferers, he ran Cormier by means of a gauntlet of assessments. When nothing confirmed up, he identified her with the thriller sickness. Canada was deep within the isolation of the Covid lockdown, however Marrero reassured them.

"He mentioned, there is a dozen different individuals at the very least which might be experiencing comparable issues to what you are experiencing, and I haven't got solutions for it but," stepmother Stacie Quigley-Cormier recalled. "He informed her that she wasn't alone."

There was one check Marrero could not safe: a PET scan, as a result of the hard-up province was largely reserving them for most cancers sufferers. So Cormier's dad and mom took her to Toronto for the scan and a second opinion by a number one neurologist there, Dr Anthony Lang.

After a multi-day analysis at a specialist neurology centre, Lang identified Cormier with FND. Her assessments confirmed that aware actions have been weak however pressured reflex or automotive actions have been regular and wholesome. It pointed to psychology.

The Quigley-Cormiers have been initially ready to just accept the FND analysis, they mentioned. However they left Toronto sad after Lang informed them to cease treating Cormier as if she had a terminal sickness as a result of it was reinforcing her situation.

Lang informed Cormier the abnormality was slight and bore no relation to her signs, so she should not fear about it.

The decision pushed the Quigley-Cormier household away from Lang and his FND analysis and again in direction of Marrero, who the household had come to consider in deeply. Marrero had by no means crossed "any sort of line," Stacie mentioned. "He is pristine."

"That is why all his sufferers like him," Andre mentioned. "Love him, possibly."

Marrero continued to check Cormier repeatedly. He prescribed anti-seizure treatment to stop potential seizures, although she had not had any. He referred her for a spherical of intravenous immunoglobulin remedy — which she mentioned precipitated extreme complications, aches, nausea, dizziness and aseptic meningitis — and prescribed a strong intravenous immunosuppressant used for blood cancers and autoimmune sicknesses. Neither improved her situation.

Cormier as soon as dreamed of finding out pathology. However her sickness precipitated her to drop out of college and for years she has gone all over the place both in a wheelchair or with a cane, residing, for a 24-year-old, a restricted life.

"I've had this concept that my life has been wasted, or that I've finished nothing with my life since I obtained sick," she mentioned.

"So, yeah, it seems like I have been robbed of that."

His name to Cormier was not solely applicable, he mentioned, he was ethically certain to speak together with her immediately as a result of she was a mentally competent grownup who didn't ask for her dad and mom to behave for her.

Over the approaching months, Lang watched with concern because the purported cluster ballooned in New Brunswick. He emailed Marrero and left messages together with his secretary providing assist, however by no means heard again. In late 2023, annoyed by what he noticed as cluster misinformation all over the place, Lang determined with colleagues to mount a examine. The outcomes — revealed in Might 2025 within the Journal of the American Medical Affiliation, JAMA — landed in New Brunswick like a hand grenade.

Lang and his co-authors — together with a number of former Thoughts Clinic colleagues of Marrero and the involved neuropathologist, Gerard Jansen — discovered that each one 25 sufferers of their examine had suffered from beforehand recognized situations, from useful neurological dysfunction to dementia to most cancers. The likelihood of there being no new illness was near 100%, they mentioned. The actual explanation for the cluster, they concluded, was serial misdiagnosis by Marrero, compounded by credulous media reporting, the constraints of New Brunswick's public well being system, institutional mistrust sown by the pandemic and the actions of a small group of individuals "co-opting the disaster to go well with their agenda".

A number of, together with Gabrielle Cormier, have been included through a consent waiver — a authorized course of which permits researchers to make use of affected person knowledge with out their categorical consent offered sure anonymity standards are met.

The examine's conclusions incensed probably the most vocal sufferers and affected person advocates, together with Kat Lanteigne and Stacie Quigley-Cormier, who allege that the analysis was unscientific and unethical. The Quigley-Cormiers are livid that Gabrielle's knowledge was used for the examine, and their legal professionals have despatched letters to Lang and to the journal alleging the paper was a violation of her privateness. JAMA declined to touch upon the dispute. Lang mentioned that the analysis was authorized, moral and appropriately anonymised. As for the alleged violation of privateness, he identified that the one cause anybody knew Cormier's knowledge was used was as a result of her father and stepmother had informed the media, together with many different particulars about her life.

A stone fountain burbled softly in his Japanese-inspired peace backyard. Birds sang in his personal patch of forest — untouched by herbicides or pesticides, he mentioned.

Marrero is undeniably charismatic. He has a heat smile and manner. He speaks gently, however with authority. He remembers small particulars about individuals he barely is aware of and asks about their wellbeing in a fashion that conveys real care.

Settled in his workplace chair, he recalled with apparent pleasure that not so way back, a few of Canada's high scientists had sat with him round that very desk, able to tackle a scientific thriller. However now, Marrero appeared more and more remoted.

"They're making an attempt to current me because it," he mentioned, dejectedly. "I used to be a part of it, however I used to be not it. The one distinction is, when the desk was empty, I stayed."

Of Marrero's early federal collaborators — Drs Coulthart, Cashman, Sturdy, and Weiss — solely Coulthart agreed to talk to the BBC concerning the cluster. He denied ever having been satisfied by the concept of a unified, thriller syndrome. "As a scientist, I exploit the phrase satisfied very, very sparingly," he mentioned. "However do not let anyone child you — if anybody says they know what is going on on or is not happening in New Brunswick, they're both mendacity or grossly mistaken. As a result of no person has the info."

An upcoming provincial report may supply some solutions. In contrast to the earlier research, it would look at the claims of elevated glyphosate and heavy metals within the sufferers. At occasions, the stakes appear impossibly excessive. "Lives hold within the steadiness," learn a current letter to Premier Susan Holt, signed by 72 of the sufferers. "It's inside your energy to honour them, cherish them, and look after them," the letter mentioned. "Or you may abandon them and allow them to wither, fade, and finally die. Please be part of us on the fitting aspect of historical past."

The affected person advocates, led by Bloodwatch director Kat Lanteigne, have arguably finished greater than anybody to maintain the story of the cluster going, with an operation that features lobbying the federal government, briefing the press and sending authorized letters to scientists.

Lanteigne has publicly attacked each Jansen and Lang over the JAMA examine, branding their work inaccurate and unethical. She denied harassing Jansen, saying she had by no means spoken to him immediately and emailed him solely as soon as. "I've a document of talking fact to energy and I've at all times labored with integrity and honesty," she mentioned.

Each Lang and Jansen are standing their floor.

"What now we have here's a case of misdiagnosis, evolving to misinformation, and sadly leading to struggling for sufferers and households," Lang mentioned.

"I might even go additional," Jansen mentioned, relating to the alleged misdiagnosis of the sufferers. "I might say they're being abused."

Few others are keen to criticise Marrero so overtly. Privately, former senior authorities officers and colleagues of Marrero have questioned whether or not he ought to have been investigated. The Royal School of Physicians informed the BBC it couldn't touch upon whether or not there had been complaints in opposition to any particular person doctor, and none have been made public in relation to Marrero. Any sanction course of would sometimes start with a grievance.

And that was the difficulty, one former senior well being official mentioned.

"It needs to be a affected person grievance," they mentioned. "And all his sufferers love him."

Kat Lanteigne informed the BBC that Marrero "deserves the Order of Canada for what he has finished for these individuals." However many sufferers, like Lucas, are languishing. Largely untreated, they've undergone check after check in quest of the thriller illness and ended up again the place they started, or someplace worse.

In response to criticisms on this story, Marrero mentioned that he wouldn't touch upon sufferers or fellow physicians. "The main target should stay on the tons of of struggling sufferers, their households and communities who have to be the guts of our consideration and care," he mentioned.

Canada has among the many world's most permissive legal guidelines for assisted dying, permitting individuals to pursue it with no terminal analysis.

When Lucas informed Marrero her plan, he grew to become "choked up", she mentioned. "It eats him up, he is preventing again tears."
