Given the breadth of measures and longitudinal design, Add Health offers a unique opportunity to explore the early origins of cognitive functioning and to track changes in dementia risk within a nationally representative cohort that has&nbsp;been followed&nbsp;since early adolescence. A key objective of Wave VI of Add Health was&nbsp;to significantly expand the measurement of cognitive domains. This wave introduced the Add Health Cognitive Assessment, Physical, and Sensory Function (Add CAPS) battery, designed to support long-term tracking of cognitive, physical, and sensory function. These data provide a foundation for identifying early midlife signs of cognitive impairment that may help map future risk for Alzheimer&rsquo;s disease and Alzheimer&rsquo;s disease related dementias (AD/ADRD). The inclusion of&nbsp;<em>TestMyBrain</em>&nbsp;(TMB) reflects our commitment to collecting web-based cognitive measures in early midlife among a nationally representative sample. This approach also enables comparison with standard in-person assessments, helping to evaluate the feasibility and value of remote cognitive testing at scale in Add Health.
