Change in cognitive functioning is characteristic of normal aging and is evident beginning in mid-life. However, changes in cognition also may be associated with underlying pathology such as Alzheimer Disease.  

The research team, led by Dr. Holly Tuokko and  funded by the Alzheimer  Society of Canada and the Pacific Alzheimer Research Foundation, is  examining detailed information about the cognitive performance of English and French-speaking participants in the Canadian Longitudinal Study on Aging (CLSA). The researchers are characterizing typical performances of  neurologically healthy people on the cognitive measures employed in the CLSA for use as standards when identifying cognitive impairment. They are also  developing various easily-accessed, plain language tools (e.g., derived variables, online tools for generating cognitive classification) for use by clinicians and researchers regarding cognitive functioning as measured in the CLSA.
