Hallmarks of Brain Aging: Adaptive and Pathological Modification by Metabolic States

Abstract

During aging, the cellular milieu of the brain exhibits tell-tale signs of compromised bioenergetics, impaired adaptive neuroplasticity and resilience, aberrant neuronal network activity, dysregulation of neuronal Ca2+ homeostasis, the accrual of oxidatively modified molecules and organelles, and inflammation. These alterations render the aging brain vulnerable to Alzheimer’s and Parkinson’s diseases and stroke. Emerging findings are revealing mechanisms by which sedentary overindulgent lifestyles accelerate brain aging, whereas lifestyles that include intermittent bioenergetic challenges (exercise, fasting, and intellectual challenges) foster healthy brain aging. Here we provide an overview of the cellular and molecular biology of brain aging, how those processes interface with disease-specific neurodegenerative pathways, and how metabolic states influence brain health.

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

  • Diffusion MRI indicates age-related changes in white matter connectivity between prefrontal and posterior cortical regions and within posterior sensory cortices.

    “Diffusion MRI methods have shown age-related changes in white matter connectivity between prefrontal and posterior cortical regions, and within posterior sensory cortices.25–27”

    From Maintenance, reserve and compensation: the cognitive neuroscience of healthy ageing (2018) · cites this paper as [27]

    The 'Aberrant Neuronal Network Activity' section says white matter integrity is compromised during normal aging and describes age-related changes in functional connectivity. It does not say that diffusion MRI showed changes specifically between prefrontal and posterior cortical regions or within posterior sensory cortices. No page number is available in our copy.

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.
