Investigating Risk and Protective Factors for Dementia in a Multi-Ethnic Cohort

What is this Study about?

The aim of our study is to better understand whether certain lifestyle factors (such as physical activity and hearing) are related to early changes in memory and thinking abilities in older adults. We are especially interested in enrolling individuals who are South Asian or East Asian, because little research has focused on brain health in Canadians of diverse racial/ethnic backgrounds.

By participating, you will help us better understand how lifestyle factors are related to memory and thinking changes in adults from diverse communities. We hope that this will lead to improved prevention and early intervention strategies for dementia.

What Will Happen in This Study?

You will be asked to come into Sunnybrook 1-2 times per year for 5 years. During those visits, you may complete some of the following:

- tasks assessing your memory and thinking

- questionnaires about your background and health

- a fasting blood draw

- a brain MRI scan

- an assessment of your walking and balance

- an assessment of your blood pressure, height, weight, etc.

Each visit will last 4-5 hours. In between visits, you may be asked to wear a movement tracker for two

weeks.

You are eligible to participate if you…

- Are 55-85 years old

- Have no major medical or psychiatric diagnoses

- Are comfortable speaking and reading English
