The severity of ADHD can be modulated by the quality of the early childhood environment, lending support for early interventions.

New algorithm improves ability to generate better genetic predictors
Researchers now have a new, more refined tool, the Polygenic-Risk-Score (PRS) on Spark, to help them understand an individual’s genetic risk for common illnesses, including mental illnesses. In an initial validation study, the newly developed software package successfully generated a polygenic risk score for a cohort of Canadian women that explained and predicted more of […]
LUDMER CENTRE TAKES OPEN SCIENCE TO THE NEXT LEVEL
Since arriving at McGill and the Montreal Neurological Institute and Hospital more than 30 years ago, Alan Evans has helped the University and its network of affiliated hospitals build one of the world’s largest infrastructures of neuroscience research – from the high-resolution Big Brain atlas to supercomputing data-storage technology. These developments and others by his fellow researchers […]
Meet Dr Patricia Pelufo Silveira
What do conditions such as stress, diabetes, and mental illnesses have in common? The answer, one in which Dr Patricia Pelufo Silveira excels, is the search for a shared origin story. Dr Silveira is an Associate Professor in the Department of Psychiatry at McGill University, a researcher at the Douglas Mental Health University Institute and a Primary […]
Eczema, an early warning sign for potential mental illness
Eczema may be an early warning sign for potential mental health problems. According to Dr Patricia P Silveira, “When treating young girls for childhood cutaneous allergies, such as eczema, healthcare professionals should be aware of the increased potential for vulnerability for mental health problems. Understanding and investigating these types of associated risks is crucial to […]
Infant nutrition linked to healthy adult body weight
The long-term consequences of poor infant nutrition, particularly in the first weeks after birth, are becoming clearer thanks to a new study. Preterm, underweight babies who benefited from a higher energy intake –specifically more protein and fats- during the first three weeks of life had healthier body weights in their 20s (as measured by a […]
Sugar cravings may be due to dopamine dysfunction
Moving beyond the overly simplistic unhealthy lifestyle paradigm, researchers are slowly uncovering the genetic and epigenetic mechanisms behind obesity. Recent research by Ludmer Centre researcher Dr Patricia P Silveira at McGill and the Douglas Institute and her colleagues has shown that altered dopamine signaling may increase a preference for more palatable high-sugar foods leading to a risk […]
What happens in the womb matters to your child’s mental health
We can now project the potential impact of adversity in the womb on a child’s development and their risk of developing a mental illness as an adult. Ludmer Centre researchers and an international team led by Dr Patricia P Silveira at the Douglas Mental Health University Institute and McGill University have created the first screening […]
Limitations of birth-weight cutoffs to define long-term vulnerability
New research highlights the limitations of using standard birth-weight cutoffs to define long-term vulnerability. Children born too small or too large are at increased risk for several diseases later in life, including metabolic and mental-health problems. Early identification is important to initiating proper and close follow-up; however, Ludmer Centre researchers and collaborators led by […]
Could our DNA decrease susceptibility to stress and overeating?
Could a genetic variant in our DNA decrease susceptibility to stress and overeating? Glucocorticoids, which are linked to overeating, regulate our body’s energy supply in response to stress. Ludmer Centre researcher Dr Patricia P Silveira and colleagues from research institutes in Brazil, Toronto and Montreal found that adolescents who carry an A3669G variant of the […]
