University of Sherbrooke Researchers Target Autism Biomarkers for Earlier Diagnosis
The Quest for Early Detection
Researchers at the University of Sherbrooke are embarking on a groundbreaking study aimed at revolutionizing autism spectrum disorder (ASD) diagnosis. The core of their inquiry lies in identifying specific biomarkers present in blood and urine samples of individuals with ASD, but absent in those without the condition. This enterprising goal seeks to dramatically reduce the current lag time in diagnosis, offering hope for earlier intervention and improved outcomes for children and families across the U.S.
Currently, in the United States, the average age of autism diagnosis can be between 4 and 5 years old. This delay can significantly impact a child’s developmental trajectory, as early intervention programs are most effective when started before the age of three. By identifying these biomarkers, the Sherbrooke team hopes to drastically reduce this waiting period.
Harnessing Genetic Medicine for Autism Research
Spearheading this vital research is Christiane Auray-Blais, a seasoned researcher professor at the University of Sherbrooke (UDES) and the Research Center of the centre Hospitalier Universitaire de Sherbrooke (CHUS). With decades of experience in genetic medicine, Auray-Blais is uniquely positioned to translate her in-depth knowledge into tangible advancements in autism research.
Auray-Blais emphasizes the critical importance of early diagnosis: Symptoms [de l’autisme] will manifest themselves when the children are going to be around two years old. Before arriving at a final diagnosis, it can take four to five years, explains Christiane Auray-Blais at the microphone of Here the info. Do you imagine you lost time and during wich we could provide care for these children?
This “lost time,” as Auray-blais calls it, represents a crucial window of opportunity where targeted interventions can have the most significant impact. Consider, such as, the Early Start Denver model (ESDM), a developmental intervention that blends behavioral and relationship-based approaches. Studies have demonstrated that ESDM, when implemented early, can led to significant improvements in cognitive abilities, language skills, and social interaction for children with autism. the earlier the intervention, the greater the potential for positive long-term outcomes.
The Promise of Early Intervention
Studies have shown that interventions before the age of four are associated with gains in terms of cognition, language and adaptive behavior.

The potential benefits of early intervention are well-documented.From improved communication skills to enhanced social interaction and greater independence, early interventions can dramatically alter the life course of individuals with ASD. Programs that incorporate speech therapy, occupational therapy, and applied behavior analysis (ABA) have all demonstrated effectiveness in supporting children with autism to reach their full potential.
Prevention, Innovation, and Research: A Three-Pronged Approach
Auray-Blais highlights the core principles driving her research:For me, there are three vital words: prevention, innovation and research. When prevention is done, patients can be promoted and avoid severe clinical disorders afterwards.
This philosophy emphasizes the importance of proactive identification and intervention to mitigate the severity of autism-related challenges. Take, for instance, the Children’s Autism Metabolome project (CAMP), a large-scale study that identified a subgroup of children with ASD exhibiting dysregulated branched-chain amino acid metabolism. This finding suggests that metabolic interventions, such as dietary modifications or targeted supplements, could perhaps alleviate certain symptoms in this specific subgroup. This is just one example of how innovative research can lead to preventive strategies that improve outcomes for children with ASD.
Though, there are counterarguments to consider. Some researchers caution against over-reliance on biomarkers, emphasizing the heterogeneity of ASD and the potential for misdiagnosis or overdiagnosis. They advocate for a thorough assessment approach that integrates biomarkers with clinical observations and behavioral assessments. It’s crucial to acknowledge these counterpoints and ensure that biomarker-based diagnostics are used judiciously and ethically.
Looking Ahead
Auray-Blais is optimistic about the future: By the end of the year, I hope to have convincing results that will be published

The U.S. autism community eagerly awaits the results of the study. If successful, this research could pave the way for widespread implementation of biomarker screening programs, leading to earlier diagnosis, earlier intervention, and ultimately, improved quality of life for individuals with autism and their families.
Simultaneously occurring, resources are available for families in the U.S. seeking support and details.Autism Speaks and the Autism Society of America are two prominent organizations that provide valuable resources, advocacy, and community support for individuals with autism and their families.
