First there was her partner, than everyone else she heard about. Struck by the number of cases of amyotrophic lateral sclerosis (ALS) near Windsor, in Estrie, Julie Dubois convinced Public Health to take an interest in it. Close-up on this long-term investigation.
What is ALS?

Also called Lou Gehrig’s disease, ALS is a neurodegenerative disease for which there is no cure.Eight out of ten patients die two to five years after diagnosis. The spouse of Mme Dubois, Marco Brindle, has been ill for a little over three years. He died last January, at age 61. “He was rendered quadriplegic, with assistance in breathing. The only thing that still worked in his body was his speech,” says M.me Dubois on the phone.
What is happening in Estrie?
Since her partner passed away, Mme Dubois learned of three other cases of ALS “within a five kilometer radius” in 2024. Over a longer period, she “listed, by word of mouth, 18 people” near Windsor and Richmond. Including the rest of the MRC of Val-Saint-François and Sherbrooke, it has “more than fifty names”.

Is it a lot?
The disease affects two to five people per 100,000 inhabitants, notes the Dre angela Genge, director of the ALS clinic at The Neuro (Montreal Neurological Institute-Hospital).Windsor and Richmond have a total of just over 6,000 inhabitants. “The first step is to check if there are actually more people affected than what could be expected for this community,” indicated the Estrie Public Health Department by email. In particular, it is indeed necessary to “determine whether the cluster of cases comes from one or two families affected by a genetic form of ALS
Quebec Investigates Potential ALS Cluster
Quebec public health officials have launched an investigation into a potential cluster of amyotrophic lateral sclerosis (ALS) cases in the province.The investigation, announced earlier this week, aims to determine if the number of ALS diagnoses exceeds typical rates and to explore potential environmental causes.
The investigation was prompted by concerns about a higher-than-expected number of ALS cases in a specific region. While the exact number of cases involved hasn’t been publicly released, Dr. Angela Genge, director of the ALS clinic at the Montreal Neurological Institute-Hospital, stated that the cluster represents “10 to 15% of cases.” She is serving as a key contact for the investigation.
Unraveling the Mystery: A Lengthy Process
Determining whether the observed increase in ALS cases is statistically significant will require several weeks of data analysis. Public health officials acknowledge that even if an elevated number of cases is confirmed, a extensive investigation into potential environmental causes could take “several years.” This lengthy process underscores the complexity of identifying environmental triggers for diseases like ALS.
The investigation’s findings will be crucial not only for Quebec but also for understanding ALS more broadly. While the exact causes of ALS remain unknown, research suggests a complex interplay of genetic and environmental factors. This investigation could shed light on potential environmental contributors and inform preventative measures.
The situation mirrors similar investigations in other parts of the world where clusters of rare diseases have prompted inquiries into potential environmental links. The long-term nature of the investigation highlights the need for patience and sustained commitment to understanding the root causes of this devastating disease.
Unraveling the Mystery of ALS: A Search for Industrial Causes
Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig’s disease, remains a devastating neurological illness with an elusive cause. While genetic factors play a role in some cases, researchers are increasingly exploring potential environmental triggers, including industrial exposures. A recent investigation highlights the urgent need for further research into this critical area.
The Search for Industrial Links
Studies have examined various potential links between ALS and occupational hazards. Research has focused on groups with high rates of the disease, such as American football and Italian soccer players, and even American military personnel. Investigations have also explored the potential role of exposure to cyanobacteria found in northeastern U.S. lakes. Though, as Dr.Genge notes, “it has not been reported in the literature” that a definitive industrial cause has been identified.
Despite the lack of conclusive evidence, the search for answers continues. The importance of this research is undeniable. As one advocate passionately stated, ”I’m like Marco: there is a solution, there is an answer somewhere, we have to look as if we don’t move forward, nothing will happen,” emphasizing the urgency of the situation.
The Importance of Continued Investigation
The ongoing investigation into potential industrial causes of ALS is met with cautious optimism. Dr. Genge expressed satisfaction with the seriousness given to the research, stating, “I was very happy that they took it seriously because it shows that they understand the importance of it.” This sentiment underscores the growing recognition of the need for comprehensive research into environmental factors that may contribute to the progress of this debilitating disease.
The search for answers continues, driven by the hope of finding preventative measures and ultimately, a cure for ALS. Further research into industrial exposures and other environmental factors is crucial in understanding the complex etiology of this devastating disease and improving the lives of those affected.
This article discusses a potential cluster of Amyotrophic Lateral Sclerosis (ALS) cases in Quebec, Canada, particularly focusing on the Estrie region.
Here are the key points:
Potential Cluster: Residents in the Estrie region,specifically Windsor and Richmond,have reported a higher number of ALS cases than expected. Julie Dubois, who lost her partner to ALS, noted knowing over 50 people in the area who have been diagnosed.
Investigation Launched: Quebec public health officials are investigating the situation to determine if the number of cases exceeds typical rates and to explore potential environmental causes.
Statistical analysis: Data analysis will take several weeks to determine if the observed increase in cases is statistically meaningful.
Lengthy Investigation: Even if a significant cluster is confirmed, finding specific environmental triggers for ALS could take several years due to the complexity of the disease.
* Expert Involved: Dr. Angela Genge, director of the ALS clinic at the Montreal Neurological Institute-Hospital, is a key contact for the investigation and stated that the cluster represents “10 to 15% of cases”.
The article highlights the concerns of residents and the rigorous investigative process required to understand this potential ALS cluster and its possible causes.
