Psychiatric genetics and child neurodevelopment program: characterizing infant risk pathways for the prevention of schizophrenia, bipolar disorder and major depression

Dr. Michel Maziade, a clinical psychiatrist and researcher, has led a research program for more than 35 years on families affected by schizophrenia, bipolar disorder or major depression. The risk of developing these disease in children born to an affected parent is 15 to 20 times higher than that of other children. His work has shown that healthy children who are born to an affected parent can, early in life, carry indicators of brain dysfunction that adult patients themselves have. These discoveries open doors to prevention.

Personalized neuromedicine to treat and prevent psychiatric illness.

Dr Maziade's research, which combines family genetics, neuropsychology, electroretinography,  and developmental and clinical measures, has led to a better understanding of the trajectory of major psychiatric illnesses. This knowledge helps develop interventions in personalized neuromedicine adapted to the profile of high risk youth. This will change the supply of early health services before the onset of the first symptoms of the disease, delaying the onset of the disease, reducing its severity or completely preventing the occurrence of the disease. Clinical applications of this research is delivered through the HoPE program of the CIUSSS de la Capitale-Nationale.

Dr. Maziade is also the founding Director of the Université Laval Robert-Giffard Research Center, now known as the CERVO Research Center. He directed the Research Centre from its foundation in 1987 until 2013. He is now the Director of the Centre for Personalized Neuromedicine and Child Neurodevelopment of the Cervo Center.

Dr. Michel Maziade is Full Professor of Psychiatry at the Faculty of Medicine, Laval University, as well as a practicing psychiatrist. He is currently working with the Centre de recherche du Centre intégré universitaire de santé et de services sociaux de la Capitale-Nationale (CIUSSS-CN). Founding director of the Centre de recherche of the Institut universitaire en santé mentale de Québec (CRIUSMQ), he holds a senior Canada Research Chair in the Genetics of Neuropsychiatric Disorders. In 2011, he has been appointed Knight of the Ordre national du Québec by the Prime Minister of Quebec in acknowledgment for his research deeds. He has also obtained prestigious distinctions, such as the J. M. Cleghorn Prize from the Canadian Psychiatric Association in 2008, and the Dr. Alexander Gralnick Award from the Child Welfare League of America (CWLA, Washington D.C.) in 2013 in recognition of his excellent work on the childhood roots of affective and non-affective disorders. He was nominated Fellow of the American Psychiatric Association in 1993 and promoted Distinguished Life Fellow in 2012. Practicing psychiatrist and scientist, he is renowned for his pioneering work on the genetics of schizophrenia and mood disorders. With his team, he has developed an approach combining developmental psychopathology, neuropsychology, electroretinography and family genetics to investigate the childhood and neurodevelopmental roots of major psychiatric disorders. His expertise in developmental psychopathology made him uncover the presence of risk endophenotypes such as cognitive dysfunctions in offspring of parents affected by schizophrenia and bipolar disorders. He has conducted longitudinal and transversal studies over 25 years on families from eastern Quebec affected by these diseases.
