Research
The Gawryluk team has been involved in a number of different research projects which have shown success through extensive publications & conference presentations.
We are broadly interested in :
- Trajectories of healthy aging
- Earlier indicators of dementia
- Women’s brain health
- Perspectives of Indigenous people on brain health
- Neurocognitive changes and aging in Multiple Sclerosis
- Dementia Friendly Communities
