UOJM is pleased to have collaborated with the Brain Health Research Day committees to put together this special issue. The abstracts found in these conference proceedings highlight the quality and diversity of ongoing research at the University of Ottawa Institute of Mental Health Research, Children’s Hospital of Eastern Ontario (CHEO), Savoir Montfort, Élisabeth Bruyère Hospital, the Ottawa Hospital Research Institute, the University of Ottawa Heart Institute, and l’Université du Québec en Outaouais, of which we are incredibly proud. We’d like to thank all members of the Brain Health Research Day committees, the UOJM team, and all students involved for their hard work in contributing to and finalizing this special issue.
