Abstract

Memory decline in aging results from multiple factors that influence both executive function and the medial temporal lobe memory system. In advanced aging, frontal-striatal systems are preferentially vulnerable to white matter change, atrophy, and certain forms of neurotransmitter depletion. Frontal-striatal change may underlie mild memory difficulties in aging that are most apparent on tasks demanding high levels of attention and controlled processing. Through separate mechanisms, Alzheimer's disease preferentially affects the medial temporal lobe and cortical networks, including posterior cingulate and retrosplenial cortex early in its progression, often before clinical symptoms are recognized. Disruption of the medial temporal lobe memory system leads directly to memory impairment. Recent findings further suggest that age-associated change is not received passively. Reliance on reserve is emerging as an important factor that determines who ages gracefully and who declines rapidly. Functional imaging studies, in particular, suggest increased recruitment of brain areas in older adults that may reflect a form of compensation.

  • The l-dlPFC is integral to higher-order cognition and modulates episodic memory in MCI by enhancing encoding and facilitating retrieval.

    “l-dlPFC is integral to higher-order cognition (i.e., executive function) [10,11], which modulates episodic memory in MCI by way of enhancing encoding and facilitating retrieval [12–14].”

    From A phase I trial of accelerated intermittent theta burst rTMS for amnestic MCI (2024) · cites this paper as [12]

    The passage labeled Abstract (page unavailable) says that declining executive function impairs strategic processing at encoding and retrieval, supporting a general link between executive function and memory. It discusses age-associated frontal-striatal changes, but does not establish this mechanism specifically for the left dorsolateral prefrontal cortex or for people with MCI. (LLM, conf=0.86)

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.
