    Aging is associated with significant inter-individual effects on function, morbidity, and mortality


    Brain age is an examination of biological aging from a neuroanatomical perspective


    Many studies examining variability in the biology of aging are limited by participant chronological age variability, reliance on retrospective data collection, and heterogeneity in image acquisition and processing


    Brain age is a neuroimaging-based biomarker thought to reflect changes during brain aging and predict longevity


    The Lancet journal LANCET HEALTHY LONGEVITY recently published a study by Aaron Z Wagen et al.


    The study applied a well-established model of brain age to obtain brain-PAD from structural imaging of Insight 46 participants


    A total of 456 patients (225 women) were included in the study, with a mean age of 70.


    Brain predicted age compared to actual age and gender
