Abstract

BACKGROUND: Active lifestyles are related to better cognitive aging outcomes, yet the unique role of different types of activity are unknown. OBJECTIVE: To examine the independent contributions of physical (PA) versus cognitive (CA) leisure activities to brain and cognitive aging. METHODS: Independent samples of non-demented older adults from University of California, San Francisco Hillblom Aging Network (UCSF; n = 344 typically aging) and University of California, Davis Diversity cohort (UCD; n = 485 normal to MCI) completed: 1) self-reported engagement in current PA and CA (UCSF: Physical Activity Scale for the Elderly and Cognitive Activity Scale; UCD: Life Experiences Assessment Form); 2) neuropsychological batteries; and 3) neuroimaging total gray matter volume, white matter hyperintensities, and/or global fractional anisotropy. PA and CA were simultaneously entered into multivariable linear regression models, adjusting for demographic characteristics and functional impairment severity. RESULTS: Brain outcomes: In UCSF, only PA was positively associated with gray matter volume and attenuated the relationship between age and fractional anisotropy. In UCD, only CA was associated with less white matter hyperintensities and attenuated the relationship between age and gray matter volume. Cognitive outcomes: In both cohorts, greater CA, but not PA, related to better cognition, independent of age and brain structure. In UCSF, CA attenuated the relationship between fractional anisotropy and cognition. In UCD, PA attenuated the association between white matter hyperintensities and cognition. CONCLUSIONS: Although their specificity was not easily teased apart, both PA and CA are clearly related to better brain and cognitive resilience markers across cohorts with differing educational, racial, and disease statuses. PA and CA may independently contribute to converging neuroprotective pathways for brain and cognitive aging.

  • People who engage in moderate to vigorous exercise on more days have relatively larger brain volumes than those who do less or no exercise.

    “People who engage in moderate to vigorous exercise on more days have relatively larger brain volumes than those who do less or no exercise. (173) (174)”

    From Dementia prevention, intervention, and care: 2024 report of the Lancet standing Commission (2024) · cites this paper as [174]

    The Results (Brain integrity and brain resilience to age; page not available) report that greater physical activity was associated with larger gray matter volumes in the UCSF cohort. The Methods (Current physical and cognitive activity lifestyle measurement; page not available) describe an activity score covering recreational, household, and work activities, not a comparison based specifically on days of moderate-to-vigorous exercise. The finding is also specific to gray matter volume and that cohort, rather than brain volumes in people generally. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
