A bit of a messy situation, since there is both documented precedent for undisclosed chemical use to cause severe population illness (e.g. numerous times in "cancer alley"), however there is also precedent for charismatic doctors to create a cult of personality that might create noise.

yeah I agree. this is really unfortunate because it seems that there is something systemic here at play which has become twisted up in a cult of personality and that's made a rigorous scientific investigation very difficult

This is such a frustrating situation to read about, because it is clear that Dr. Marrero is out of his depth, but it’s also clear that whatever this cluster is - real or imagined - was horribly mismanaged by the health officials in charge.

The fact that the investigation was disbanded simply because the patients had symptoms that can be tied to existing diseases is utterly asinine. As if there’s no reason to investigate why so many people in such a small area have similar conditions, or even to investigate whether or not the demographics of the supposed cluster are out of the ordinary in the first place. Even if there was no related cause at all, such an investigation could be used to determine that Dr. Marrero was the cause of a problem and stop him from doing harm. But instead the result was that no satisfactory conclusion was reached for the majority of people, and the patients continue to suffer.

These people need help and they are being failed by their doctors, their administrative officials and their representatives all at the same time.

The doctor is a distraction that keeps tripping up everyone here. Once the real cause is discovered, he will move on. If a real cause is not discovered, it's probably due to an insufficient investigation, in which case the investigation should continue.

These sick people there need to move out permanently to go live far away from the province and see if they get better. If it's prion disease, they probably won't reliably get better by moving alone. They also should do private testing for heavy metals.

There is an experimental existing drug combo of trimipramine+fluphenazine that might help prion disease but it won't cure it: https://medicalxpress.com/news/2011-09-screen-antidepressant.... The corresponding paper is https://pubmed.ncbi.nlm.nih.gov/21931860/

The Canadian government looks to have both failed and abandoned its people. It could have tested them, profiled the disease, understood its cause, and tried treatments, but it looks to just not care.

In the simple case, if it's just a neurotoxin, it might show signs of getting better upon moving out.

Deep dive into New Brunswick, JD Irving, and their ongoing issues with Glyphosate pollution. Canadian researchers specializing on CJD have been blocked from investigating this case [0].

Sadly, the Irvings have extremely close ties with both the Liberals [1] and Conservatives [2][3] and are essentially untouchable due to Canada's parliamentary nature.

The NYT has been doing an on-the-ground report on this issue for a couple years now [4][5]

It reminds me of similar stories I heard while growing up from family friends of mine who ran a construction business on Vancouver Island and the Lower Mainland about how cheap it was to "lobby" and get a personal meeting and photograph with Martin and Harper, and this was after Railgate.

The doctor in question here explicitly pointed out increased levels of glyphosate in their blood:

> He also warned that some patients' blood work showed elevated levels for compounds found in herbicides such as glyphosate, and said more testing should be done to rule out environmental toxins, including the neurotoxin BMAA, which is produced by blue-green algae.

>untouchable due to Canada's parliamentary nature.

This is an odd sentence to me, I assume there’s some reasoning under there that makes sense to the writer, but it doesn’t follow to me. It feels ‘just so’ to me, like there more to this than simply they can’t do anything because parliament.

Margins in the House of Commons have been paper thin for decades, and this gives inordinate power for MPs to threaten a no-confidence motion behind closed doors.

In a province like NB where most politicians from both parties either solicits donations from Irving or are former Irving careerists(eg. the former Premier Higgs who was Irving's CFO), it gives Irving's leadership an inordinate amount of power.

My relative who owns a construction business would do something similar in Punjabi heavy ridings in BC as well - he's become fairly prominent in the Gurdawara and Mandir circuit, and because most older Punjabi Canadian voters don't really follow English language news (and in some cases cannot even speak English), they tend to defer to the candidate and party that the Gurdawara or Mandir committee makes a hukumnama for. In ridings across much of BC, there are enough of these kinds of Punjabi voters (Sikh and Hindu) that MPs will try to co-opt these committees to become their de facto enforcers for the community.

Eric Adams in NYC used similar immigrant machine politics which landed him on the FBI radar, because the old country's intel organizations continue to monitor their diasporas, and oftentimes leverage them tactically, which led him to being caught in the dragnet due to two separate investigations into Turkish [0] and Chinese [1] influence ops in NYC.

It feels like now you're saying it's not because it's parliament's nature to be like this, but rather these other factors that occure within parliaments and other systems?

Can't you unelect the MPs? Doesn't the paper thin margins increase those odds? Honestly, it doesn't sound like the issue is a parliamentry system, but rather people either aren't aware of the issues (media), or have decided (wrongly or rightly) not to care. Either way I still don't get how that's the parliamentry nature as much as it's the people's. That's kind of the point of these systems.

I don't know enough about Candaian Punjabi dispora to comment about the other stuff.

> Can't you unelect the MPs

All MPs in NB need to kiss the ring, otherwise they'll face a well funded challenger.

Furthermore, 1 out of every 7 NBers are employed by JDI and Irving Oil.

> Either way I still don't get how that's the parliamentry nature as much as it's the people's. That's kind of the point of these systems

The ability to threaten a no-confidence motion means individual MPs can have an outsized impact on the executive branch.

If it was glyphosates, this would be a much more widespread problem. Roundup/glyphosates are used extensively all across the US and we would be seeing similar statistics everywhere.
tptacek 15 hours ago|||
Also it's "glyphosate", right? Not "glyphosates". It's not like some weird class of industrial chemicals; it's a specific herbicide, used since 1975, more commonly known as Roundup, notable because Monsanto owns patents on genetically-modified crops that are resistant to it.
culi 13 hours ago||
They're probably referring to the different salts (isopropylamine (IPA), potassium, or diammonium) which can greatly affect absorption and effectiveness
tptacek 13 hours ago||
Roundup is IPA, Touchdown is DAM. Both extremely common.
culi 13 hours ago||
Yeah both glyphosate.

But the doctor in the OP explicitly pointed out that they had increased levels of glyphosate in their blood:

> He also warned that some patients' blood work showed elevated levels for compounds found in herbicides such as glyphosate, and said more testing should be done to rule out environmental toxins, including the neurotoxin BMAA, which is produced by blue-green algae.

https://www.cbc.ca/news/canada/new-brunswick/new-brunswick-n...

Just because glyphosate is everywhere doesn't mean it can't be concentrated in a particular place.

To be clear I'm not taking a stand for the glyphosate argument at all. I just don't think your line of reasoning is a fair counterargument in this case

0xbadcafebee 12 hours ago||
They would need to have been ingesting or breathing the glyphosate pretty recent to their blood draw. It doesn't absorb easily into skin, and it passes through you quickly. And if you do get a concentrated dose, you get nausea, vomiting, respiratory issues (if inhaled). It's a weird thing to be the culprit, since it's hard to get, and doesn't cause many issues. And it's weird to mention at all, since he says only "a few people" had elevated levels of it.

"Melissa Nicholson said her 59-year-old mother, who has suffered for four years with a neurological disorder, received test results indicating she had levels of glyphosate in her body that were 47 times higher than the acceptable level."

This is bizarre. Either she lives right next to a farm that's spraying it, and she's getting it blown into an open window in her house where she's breathing it, and then immediately went for a blood test... or she's somehow ingesting it in/around her house (like from a bottle of Roundup that keeps getting splashed on something she's ingesting).

AmbroseBierce 14 hours ago||||
You are assuming a simple direct causation, instead it could be a reaction of glyphosate with something else in their bodies that they have inhaled from the air (or from their food), perhaps a heavy metal (given those are mentioned in TFA)

The Irving family also has a near monopoly on oil refining, trucking, and other high polluting industries in NB and Maine.
alephnerd 14 hours ago|||
The region in NB where this issue is occurring is the hub for NB's and North America's forestry industry. Over 40% of all harvested forest land in NB is treated with glyphosate [0].

Commercial forestry at JD Irving's scale largely died out in much of the US excluding Maine (where it is also has inordinate political power [1][2]).

Glyphosate, not "glyphosates". Roundup. It's used everywhere. It's an extremely widely used herbicide.
alephnerd 13 hours ago||
Yes, but almost the entire cluster of the NB cases are around Caraquet NB, which is completely surrounded by softwood plantations, and this has been a case they have been fighting for years.

Additionally, Industrial scale lumber harvesting uses magnitudes more Glyphosate than a home gardener or your local HOA.

tptacek 13 hours ago||
I don't doubt something specific is going on there, but it's unlikely it's Roundup, since every suburb in North America is carpet-bombed with the stuff.

While other areas might receive high doses, I'd wonder if there is a link here to the amount of salmon and deer the people there eat, that itself consumed exposed plants or lived in exposed water, compared to the rest of the country? Or the impacts on aquifers?

I watched a documentary about Morgellons, and the patients would often seem quite reasonable at first, but the more they spoke, and the more they described their symptoms, the crazier they sounded.

One patient, whose brother, ironically, was a physician (and one skeptical of Morgellons as anything other than delusional parasitosis), seemed earnest, if intense, in describing how Morgellons had destroyed his quality of life... but then he started describing how he felt like he was able to inadvertently affect electronic devices, especially RF-based ones, because the Morgellons "fibers" in his extremities caused some kind of interference. At this point, he sounded squarely cuckoo for Cocoa Puffs.

However, one could very well imagine an infectious disease, with or without a dermatological component, causing delusional parasitosis. Maybe they have some virus or something that makes them think they have these "fibers?" Or a parasite? Toxoplasma gondii is known to affect inhibition. UTIs in the elderly are notorious for making them crazy.

jacquesm 13 hours ago||
Besides that fact that in this particular case there probably really is 'something' (it would be rare for the brain to spontaneously exhibit CJD symptoms, though it does happen this would most likely not lead to a cluster of cases), you don't need to propose an infectious disease for people that say they have symptoms where there are none, when there is ample proof of people being able to influence each other into believing all kinds of crap to the point that it becomes part of their identity.

I once had a woman and her husband visiting to inquire about buying a house I owned in Northern Groningen, pretty much as far away from anything as you could possibly get in this crowded country. They arrived in a taxi that was blanked for the day (it turned out the man was a cab driver) and after looking the place over and liking it visibly the woman said 'oh, we really like it, but there is one more thing, I am allergic to electromagnetic radiation so let me verify that' (eye roll by the man at this point). She went to the car and came back with a box with a dial on it that she had bought online (a pretty basic field strength meter, set to the most sensitive part of the range) and started walking around muttering to herself and waving the box around like a modern day dowser.

After a while of this she came to me and said she was really sorry but she had to drop her interest because the house was absolutely infested with EM fields. In Amsterdam, where they lived, they had turned their whole apartment into a cage of Faraday with copper mesh nailed against every surface (it turned out they lived right opposite the KPN microwave tower next to the RAI so maybe she even had a point, that thing featured multiple RF links beaming 100's of Watts on tight beam links between other such towers, at some point in the past these carried our long distance phone calls before fiber came along).

I asked if I could see her box for a second and pointed it at the sun: the needle pegged instantly and she was most surprised, so I explained that what she is measuring is real, but so faint that the chances of any kind of interaction with her body are most likely delusional.

Here the conversation abruptly ended...

As for TFA: prions, the agents responsible for CJD are remarkably resilient and annoying and can make it through the foodchain across the digestive barrier and into the brain and even a single one of them can cause CJD.

Perhaps a bit tangential to the main topic, but it is of course true that UTIs can adversely affect cognition in the elderly, even precipitate delirium, etc., depending on type and severity of infection. Naturally that also occurs with other sources of infection, and factors including intoxication due to drugs (prescribed or otherwise) and a host of others. Vulnerability to such decompensation is greater among those already functioning marginally. As such accurate diagnosis can be hard to establish particularly when multiple factors are implicated, hardly a rare circumstance. (At least in my physician-practice that's frequently been the case.)

I appreciate your comment pointing to the importance of carefully evaluating individuals manifesting new onset delusional ideation or other "mental" disturbance. It might be associated with an obscure condition, but likely enough it's the result of common maladies. The worst error is thinking one knows what's going on before (or not at all) thoroughly investigating the possibilities.

Do you really think there being a mass hysteria component to this, especially in the age of TikTok, doesn't warrant serious consideration? Your alarm bells didn't go off when you saw the photos and read the profiles of some of these people, especially the 18yo who supposedly needs a wheelchair and a cane?

> Cormier has featured heavily in the media coverage of the cluster, becoming a kind of poster child for the mystery disease. She was first referred to Marrero at just 18. A high school student, dancer and competitive figure skater, she had begun to experience fatigue-like symptoms and muscle soreness and then passed out at school.

> Cormier was already taking anti-anxiety medication, and the hospital emergency room doctor told her the incident was anxiety-induced.

The other young person woman contemplating MAiD is especially tragic. Hopefully the doctors do not enable her.

Except what's more likely is that it's just psychological - which doesn't mean it doesn't have physiological treatments, it's just going to be for the psyche issue though.

Put it another way: it's well recognized eating disorders exist. But they're psychological disorders: they respond to psychological interventions and treatments, and are curable, but can also "spread" in viral like ways - i.e. an eating disorder can be induced by environmental (peer group) factors.

We don't generally posit that a virus spreads eating disorders, nor has any evidence of one been identified. And so in the same way, there's no reason to think Morgellons should have any underlying pathological cause that's any different, since none has been identified but we are aware of a number of psychological self-harm disorders (which can be amplified or spread sociologically but also just be unusual presentations of other conditions).

Worth noting that in a preindustrial society, plenty of mental illness is caused by infectious agents- at minimum rabies, hookworm, syphilis- so it’s not like science doesn’t believe mental illness can be caused by an infectious agent, or has any bias against that hypothesis. Its one of the first things checked for.

FND == neurologist gaslighting the patient. Formerly known as hysteria.
whimsicalism 3 hours ago|
FND is a useful label because it helps provide clarity, feeling of responsiveness, and direction towards effective treatments like CBT, rather than calling a patient experiencing real discomfort/disability ‘hysterical’.

i do think we have to think hard about how we want to deal with the rapid expansion of FNDs and social contagion.
