The aim of this research was to identify the cognitive outcome of interviewed participants who did not progress to partake in clinical assessments in a longitudinal aging study. Selective non-response to clinical assessment in a longitudinal aging study is associated with higher risk of cognitive decline and probable dementia. Longitudinal aging studies may underestimate rates of dementia and population levels of cognitive decline.
