Environmental pollutants and brain health study

This study looks for brain/biological “signals” (biomarkers) that may identify Alzheimer’s disease earlier, including stages before clear symptoms. You may be followed for about 5 years, with repeated memory and thinking testing to see how these signs relate to future diagnosis.

This study looks at whether exposure to air pollution during youth is linked to how children grow, learn, or develop. You may be invited if your family is already part of an earlier birth cohort study and can complete questionnaires and (if needed) brain imaging safely.

This research study examines how the brain's immune system changes in older adults with memory problems, Parkinson's disease, or normal aging. By understanding these changes, researchers hope to better understand neurodegeneration and develop new treatments.

This study follows adults over time to better understand brain health and brain-related conditions. You may join if you already have certain neurological or psychiatric diagnoses, are at higher risk, or simply want to help research on maintaining brain health.

This study supports Alzheimer’s research by collecting health and thinking (cognitive) test results and blood samples to study genetics and biomarkers. You may be enrolled if you’re age 40 or older and can do these checkups, even if you have mild memory problems or dementia.

This study looks at how pollution and other environmental factors affect the health of older adults. It may help researchers understand how to keep people healthier as they age.
