about us
An interdisciplinary team of researchers
Researchers from the Graham NeuroImaging Lab at Sunnybrook Research Institute and the KL-CARE group at Rotman Research Institute are investigating differences in brain regions in those with Long Haul COVID-19. Both institutions are based in Toronto, Ontario. We have assembled a diverse team of scientists and clinician researchers to undertake this highly novel study, taking advantage of longstanding interactions between the research institutes at Sunnybrook Health Sciences Centre, Baycrest and St. Michael’s Hospital. Our team's primary areas of expertise span across MRI neuroimaging science, neuroinformatics, cognitive neuroscience, behavioural assessments, neurology and front-line critical care, ensuring a comprehensive approach to to investigate not only behavioural impairments, but also changes in brain anatomy and physiological functions of COVID-19 patients.
There are two groups of participants in this study: Group 1 are people that tested positive for COVID-19, while Group 2 are people who were negative (that is, control participants). Regardless of their COVID-19 test results, all participants will have the same assessments. We invite all participants to return for follow-up sessions involving the same tests, after 3 months, and for a third final visit that may occur 1-1.5 years after the first visit. This is to assess whether observed behavioural or brain changes resolve 3 months after the initial behavioural and MRI tests, as this is a typical period for recovery from moderate brain damage. This also helps assess any brain changes that occur across a longer time scale, up to 2.5 years after the initial behavioural and MRI tests.
In each study visit, participants will complete assessments, including an EEG assessment which measures the brain electrical signals, an MRI scan that takes about 1-1.5 hours, vision and smell tests, cognitive/thinking tasks and questionnaires about mood and emotional well-being. In addition, participants will be given the option to provide a blood sample. Blood analysis will include markers in blood that can provide a sign of disease severity and may be used for future research.
