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 is looking at how the brain works in healthy younger and older adults. You will participate in tasks and assessments that help researchers understand decision-making and brain function.

This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
