Abstract

As the number of patients with Alzheimer's disease (AD) increases, it brings great suffering to their families and causes a heavy socioeconomic burden to society. A vast amount of funds and a mass of research have been devoted to elucidating the pathology of AD. However, the main pathogenesis is still elusive, and its mechanism is not completely clear. Research on the mechanisms of AD mainly focuses on the amyloid cascade, tau protein, neuroinflammation, metal ions, and oxidative stress hypotheses. Oxidative stress is as a bridge that connects the different hypotheses and mechanisms of AD. It is a process that causes neuronal damage and occurs in various pathways. Oxidative stress plays a critical role in AD and can even be considered a crucial central factor in the pathogenesis of AD. Previous reviews have also summarized the role of oxidative stress in AD, but these mainly review a specific signaling pathway. Taking oxidative stress as the central point, this review comprehensively expands on the roles of oxidative stress that are involved in the pathogenesis of AD. The vivid and easy-to-understand figures systematically clarify the connected roles of oxidative stress in AD and allow readers to further understand oxidative stress and AD.

Claims other papers make about this one

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

  • Mitochondrial dysfunction reduces activities of essential enzymes and disrupts mitochondrial dynamics, contributing to oxidative stress in AD.

    “Key contributors to oxidative stress in AD include mitochondrial dysfunction, which reduces the activities of essential enzymes and disrupts mitochondrial dynamics.”
  • An imbalance between ROS production and detoxification leads to damage of neuronal membrane lipids, proteins, and nucleic acids, causing neuronal cell death.

    “It suggests that an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detoxify these harmful compounds leads to damage of neuronal membrane lipids, proteins, and nucleic acids, ultimately causing neuronal cell death.”
  • The oxidative stress hypothesis indicates that oxidative stress plays a crucial role in the pathogenesis of AD.

    “The oxidative stress hypothesis indicates that oxidative stress plays a crucial role in the pathogenesis of AD.”

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.
