Research

Our staff members are scientist-practitioners who embody the integration of care, research, and education. All assessment and intervention services are evidence-based, and we contribute to the development of clinical knowledge via research and evaluation of our services. Specific areas of research emphasis include normal cognitive aging, assessment and intervention in mild cognitive impairment, use of adaptive technologies for severe memory impairment, evaluation of cognitive rehabilitation and behavioural techniques, and development of neuropsychological tools.
