A Mount Allison researcher is continuing his work exploring possible causes of unexplained neurological symptoms that have been noticed in New Brunswickers over the past 8 years, and also backing the latest call for the federal and provincial governments to formally investigate.<\/p>\n
Dr. Matthew Betti is a Mount A. professor of math and computer science who specializes in modeling disease spread. Last year, he started a research survey to help narrow down possible causes or circumstances related to the over 200 people who are reportedly suffering from an atypical, unknown neurological disease in the eastern parts of New Brunswick. And last month, he signed his name to an open letter written by Moncton medical student James Paddle, calling for an immediate public health investigation.<\/p>\n
Paddle studied and later did a work placement with Dr. Alier Marrero, the neurologist who first identified patients with atypical neurological symptoms. Up until May 2021, Marrero\u2019s work was being supported jointly by New Brunswick Public Health and Public Health Canada. But then, New Brunswick cut ties with Public Health Canada, and appointed a steering committee to review the cases they had on file, which had been capped at 48. That committee later concluded that most of the 48 cases were actually attributable to known causes, and New Brunswick Public Health closed the investigation.<\/p>\n
But Marrero has continued to see more and more patients which he says have sets of symptoms he can\u2019t explain. Paddle says the number of patients is up to over 200 and the cases appear in clusters throughout eastern New Brunswick, including some cases in the Tantramar region. Patients include people of all ages, even teenagers, and according to Paddle, urine tests of those patients have returned results showing well-above detectable amounts of glyphosate and other pesticides. He also expresses concern that BMAA, a bacteria present in blue-green algae, could be related.<\/p>\n
Matt Betti is also interested in potential environmental causes of the unknown disease, but his approach to the problem appears to be in contrast to that of New Brunswick Public Health. Instead of capping case numbers at 48 and looking at just those cases, Betti has cast a wider net. His research survey is open to anyone, including people who might not be experiencing anything strange, who will serve as a control group. The idea is to hear from as many people as possible across the province, in the process capturing the hundreds that are experiencing unexplained sets of symptoms.<\/p>\n
But uptake of the survey has been slow. Betti has about 50 respondents as of July, and about 26 of those have reported symptoms fitting the profile first put together by Marrero and colleagues in January 2021. Betti says he\u2019s not that surprised at the slow uptake. \u201cI knew it was going to be tough to get people,\u201d says Betti. \u201cA grassroots approach takes a long time. Grass takes time to grow.\u201d<\/p>\n
\u201cWe\u2019re talking about people who the system has abandoned very publicly,\u201d says Betti, referring to New Brunswick Public Health\u2019s closure of their investigation. \u201cThey\u2019re probably burned out and they probably don\u2019t want to go through any sort of anything again.\u201d<\/p>\n
And Betti is clear that his study won\u2019t solve the mystery in one fell swoop. \u201cIt probably won\u2019t pinpoint a cause,\u201d says Betti, but with enough data from enough people, \u201cwe could probably determine whether this is environmental, whether it is a one factor thing or multifaceted problem.\u201d<\/p>\n
\u201cPersonally, I\u2019m not sure there is one silver bullet. I think there\u2019s a lot of environmental testing and regulation that doesn\u2019t happen in New Brunswick. And I think it\u2019s possible we\u2019re seeing the bubbling effects of all these things failing,\u201d says Betti.<\/p>\n
Betti says that with a study like the one he\u2019s conducting, the more the merrier. But even with 50 respondents, 26 of whom report symptoms matching the case definition, he\u2019s observed some things. The ages of those reporting is spread out, with a bump in those between 30 and 50 years of age. And there appears to be a geographical concentration in eastern, and mostly northeastern New Brunswick. \u201cThere\u2019s nothing weird happening in the rest of the province,\u201d says Betti. \u201cThe people that we\u2019ve spoken to tend to be located either by bodies of water or in areas of heavy forestry. Which is why I say it seems like a multi-faceted problem.\u201d<\/p>\n
Betti says he\u2019s hoping to get more respondents for his research survey, which could help identify patterns and theories that could be further explored with other testing. And he says on top of better participation in his survey, there\u2019s a lot of other work to be done, most of which involves government action.<\/p>\n
\u201cYou need to be testing waters, and testing people for things like viral encephalitis. You need to know what a baseline glyphosate level in the bloodstream is. We need to know if people who are experiencing these things have elevated levels of that. You need to know which bodies of water they\u2019ve frequented, and you need to be doing regular testing on those bodies of water, to make sure that there\u2019s no toxic algae in there. There\u2019s a ton of work that needs to be done mostly in environmental testing\u2026 There\u2019s so much to be done, and there\u2019s so little buy in to do it,\u201d says Betti. \u201cIt kind of grinds thing down to a halt.\u201d<\/p>\n
New Brunswick Public Health did respond recently to a request from Dr. Alier Marrero, and has requested the help of two federal epidemiologists to complete the extensive reporting required for the growing number of patients referred to Dr. Marrero. That work is expected to happen in early September. Memramcook-Tantramar MLA Megan Mitton says she is hoping the exercise is not designed to dismiss the concerns raised by Marrero, but rather help get to the bottom of what is adversely affecting so many people.<\/p>\n
\u201cIt\u2019s hard to understand why there\u2019s such resistance to science and to data,\u201d says Mitton. \u201cWhy would we not be doing everything possible to get answers for these patients, for these families, and for other people who may become sick because we don\u2019t really know what\u2019s going on.\u201d<\/p>\n
Betti says the onus is on the provincial government to get involved with research, and that\u2019s one of the main reasons that he decided to add his name to James Paddle\u2019s open letter.<\/p>\n
\u201cThe overarching theme of that letter is for further study. And that\u2019s exactly what we\u2019re trying to do,\u201d says Betti. \u201cOne of the things that I learned from working with the Public Health Agency and with Health Canada during COVID was that think tanks work. You get a bunch of people with different expertise in the room and ask them to solve a problem, and it works.\u201d<\/p>\n
\u201cAnd that seems to be something that\u2019s not happening here. I think it\u2019s starting to happen, but there\u2019s a long way to go.\u201d<\/p>\n
Betti is casting a wide net for his survey, looking for anyone who has lived in or spent considerable time in New Brunswick over the past 20 years. The survey can be filled out online, on paper, or over the phone.
