Brain Star Award Feature: Maira Belen Blasco, Douglas Research Institute, McGill University, won this prize based on the excellence of the research and its potential benefits to the health of Canadians. Brain Star Awards are presented by the Canadian Association for Neuroscience (CAN) and the Canadian Institutes of Health’s Institute of Neurosciences, Mental Health and Addiction
Schizophrenia is a complex psychiatric disorder typically emerging in adolescence or early adulthood. It is thought to occur because of alteration in the maturation or pruning of connexions between neurons called synapses. While this theory, called the synaptic theory is supported by genetic, stem cell and studies of brain of deceased patients, direct evidence to support this theory in living patients was doubtful. Maira Belen Blasco, working in the laboratory of Dr. Romina Mizrahi at the Douglas Research Centre, McGill University, investigated whether difference in the density of synapses could be seen in first-episode psychosis (FEP) and in clinical high risk (CHR) patients using positron emission tomography (PET). They found that synaptic density was reduced during the early stages of psychosis and its risk states and associated with negative symptoms.
