Abstract

In this review we summarize the epidemiological, cross-sectional, and interventional studies examining the association between physical activity and brain volume, function, and risk for Alzheimer's disease. The epidemiological literature provides compelling evidence that greater amounts of physical activity are associated with a reduced risk of dementia in late life. In addition, randomized interventions using neuroimaging tools have reported that participation in physical activity increases the size of prefrontal and hippocampal brain areas, which may lead to a reduction in memory impairments. Consistent with these findings, longitudinal studies using neuroimaging tools also find that the volume of prefrontal and hippocampal brain areas are larger in individuals who engaged in more physical activity earlier in life. We conclude from this review that there is convincing evidence that physical activity has a consistent and robust association with brain regions implicated in age-related cognitive decline and Alzheimer's disease. In addition to summarizing this literature we provide recommendations for future research on physical activity and brain health.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Exercise is neuroprotective, delays the onset and progression, and reduces the risk for many neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease.

    “Exercise has also been shown to be neuroprotective, to delay the onset and progression, and reduce the risk for many neurodegenerative diseases, including Alzheimer’s disease (AD) and Parkinson’s disease (PD) [17, 39, 58, 89, 108, 163, 193, 199].”

  • Increased baseline physical activity reduces the risk of developing dementia by 28% and of developing Alzheimer's disease by 45%.

    “Prospective epidemiological studies show that increased baseline physical activity reduces the risk of developing dementia by 28 % and of developing AD by 45 % [58, 83].”

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.
