UOJM is pleased to have collaborated with the University of Ottawa Brain and Mind Research Institute and the Faculty of Social Sciences to put together this special issue. The abstracts found in these conference proceedings highlight the quality and diversity of ongoing research at The Royal's Institute of Mental Health Research, Children’s Hospital of Eastern Ontario (CHEO), Savoir Montfort, Élisabeth Bruyère Hospital, and the Ottawa Hospital Research Institute. This conference marked the institute’s first in-person event since 2019 before the onset of the global pandemic and we're proud to welcome back 170 registrants safely onsite. 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.
