There’s growing concern over a mysterious brain illness in New Brunswick, Canada, and it might be more serious than what we’ve heard so far. Official numbers suggest that fewer than 50 people have been affected, but new reports hint that the real number could be much higher — possibly up to 150 cases since 2013.
What’s going on?
According to an investigation by The Guardian, many of the people affected are experiencing unexplained neurological symptoms, like memory problems, behavioral changes, and muscle spasms. In some cases, people got sick after spending time with someone else who had the illness — especially caregivers. That’s raised some eyebrows, especially since it’s extremely rare for younger people to develop these kinds of symptoms. But it’s happening.
The Suspected Culprit: BMAA
Scientists suspect a toxin called BMAA, which is produced by blue-green algae, could be playing a role. It’s been linked to diseases like Parkinson’s and Alzheimer’s, and some research shows it can build up in seafood — especially lobsters, a popular food in New Brunswick.
So why not test for BMAA in those who’ve died from the illness?
Here’s where things get frustrating. Even though some families want scientists to examine the brains of their deceased loved ones for BMAA, the New Brunswick government has reportedly blocked those tests. The concern? If BMAA is found, it could impact the local lobster industry. That’s a huge deal for the region’s economy — but what about public health?
BMAA and Brain Health
BMAA is no joke. It’s a toxin that can sneak into the brain and stay there for a long time, slowly doing damage. It may mess with the way our brain proteins fold and function, which can lead to serious brain diseases. It also seems to overstimulate brain cells and cause oxidative stress — basically putting the brain under constant pressure.
Interestingly, in lab research, the presence of L-serine (a naturally occurring amino acid) may help block some of BMAA’s harmful effects. But there’s still a lot scientists don’t fully understand.
Why Now?
Blue-green algae has been around forever, so why is it suddenly a threat? The answer might lie in climate change. Warmer temperatures and more pollution are helping algae bloom like never before — in lakes, rivers, and oceans around the world.
In fact, a study of 71 freshwater lakes showed that harmful algae blooms are increasing in almost 70% of them. These toxic blooms have already caused problems like beach closures and even pet deaths after dogs swam in contaminated water.
What’s Next?
For now, we’re waiting on an official report from health authorities in New Brunswick. But the growing number of cases, combined with possible links to environmental toxins, raises some tough questions.
Should economic interests be allowed to block scientific research that could help save lives? And are we prepared to deal with the health risks brought on by a changing climate?
As scientists continue to investigate, one thing is clear: the connection between our environment and our health is closer than we think.
