Neurobiology of schizophrenia and neurodevelopmental disorders
My main research program involves the study of pregnancy and birth complications as risk factors for the later development of schizophrenia. The causes of schizophrenia are unknown. However it is believed that schizophrenia is the result of faulty brain development, due to a combination of genetic factors and early environmental insults. Early environmental insults shown to be associated with an increased risk for the later development of schizophrenia in human populations include pregnancy and birth complications such as maternal infection during pregnancy, birth hypoxia and maternal iron deficiency during pregnancy. My laboratory uses animal models to investigate effects of perinatal complications (maternal infection during pregnancy, birth hypoxia, C-section birth, maternal iron deficiency, oxytocin administration during labor) on brain development and function (behavior, neurotransmission, hippocampal function, molecular mechanisms, etc), in relation to schizophrenia and other neurodevelopmental psychiatric disorders.
More recently I have also been involved as a Principal Investigator working with “ACCESS-Canada” the first network launched under CIHR’s Strategy for Patient-Oriented Research (SPOR) initiative. Under the direction of Ashok Malla (Lead Investigator) and Srividya Iyer (Clinical/Scientific Director), the aim of the network is to transform youth mental health services at 13 demonstration sites across Canada by 1) improving youth engagement and mental health awareness leading to early identification of those in need of services, and 2) making appropriate, evidence-informed, youth-friendly mental healthcare accessible as early as possible. The evaluative research component of the project will provide evidence on the effectiveness of the components of the transformation.

Patricia Boksa obtained her Ph.D. in 1980 in Pharmacology and Therapeutics from McGill University. In 1983, she joined the Department of Psychiatry at McGill, where she is currently a Full Professor, as well as an associate member of the Dept. of Neurology and Neurosurgery. Dr. Boksa has been a principle investigator at the Douglas Mental Health University Institute since 1983. She is a neuroscientist conducting basic research on pregnancy and birth complications as risk factors for the later development of schizophrenia. Her research involves the use of animal models to investigate effects of various perinatal complications (i.e., birth hypoxia, C-section birth, maternal infection during pregnancy) on neurodevelopmental outcomes relevant to schizophrenia. Over the years, Dr. Boksa has been continually involved with the teaching and training of students and mentoring of tenure-track academic staff in the Dept. of Psychiatry. Among other activities, she has served as a member of Senate at McGill University, as Chair and Scientific Officer on CIHR grant committees, as President of the Canadian College of Neuropsychopharmacology and as co-Editor in Chief of the Journal of Psychiatry and Neuroscience.
