Cellular senescence in brain aging and neurodegenerative diseases: evidence and perspectives

Open access

Abstract

Along with a general decline in overall health, most chronic degenerative human diseases are inherently associated with increasing age. Age-associated cognitive impairments and neurodegenerative diseases, such as Parkinson's and Alzheimer's diseases, are potentially debilitating conditions that lack viable options for treatment, resulting in a tremendous economic and societal cost. Most high-profile clinical trials for neurodegenerative diseases have led to inefficacious results, suggesting that novel approaches to treating these pathologies are needed. Numerous recent studies have demonstrated that senescent cells, which are characterized by sustained cell cycle arrest and production of a distinct senescence-associated secretory phenotype, accumulate with age and at sites of age-related diseases throughout the body, where they actively promote tissue deterioration. Cells with features of senescence have been detected in the context of brain aging and neurodegenerative disease, suggesting that they may also promote dysfunction. Here, we discuss the evidence implicating senescent cells in neurodegenerative diseases, the mechanistic contribution of these cells that may actively drive neurodegeneration, and how these cells or their effects may be targeted therapeutically.

  • The paper relies on this without support.

    The risk of developing neurodegenerative diseases increases dramatically with age.

    “The risk of developing many pathological conditions, including neurodegenerative diseases, increases dramatically with age.”
  • The paper relies on this without support.

    None of the numerous clinical trials to treat Alzheimer's disease have demonstrated a beneficial impact for patients.

    “Unfortunately, of the numerous clinical trials to treat AD, none have been able to demonstrate beneficial impact for patients.”
  • The paper relies on this without support.

    The role of senescent cells in causing and worsening neurodegenerative disorders remains unknown.

    “However, the significance of senescent cells in both the induction and exacerbation of neurodegenerative disorders is unknown.”
  • The paper relies on this without support.

    Determining the overall importance and mechanism of senescent cells in neuropathology has been very hard because tools to identify, isolate, or remove these cells are lacking.

    “To date, it has been extremely difficult to discern the overall significance and mechanistic contribution of senescent cells to neuropathology because of a lack of tools to identify, isolate, and/or eliminate these cells.”
  • The paper relies on this without support.

    These methods have not yet been used in relevant neurodegenerative disease studies.

    “To date, these approaches have not been employed for relevant studies of neurodegenerative disease.”
  • The paper relies on this without support.

    Whether and how senolytics can be translated into clinical practice is currently unclear.

    “It is currently unclear how these various senolytics can be translated into clinical strategies, if at all.”
  • The paper relies on this without support.

    No reliable method currently exists to detect the early signs of neurodegenerative diseases.

    “as there is currently no reliable way to identify the early signs of these devastating diseases.”
  • The paper relies on this without support.

    The molecular features that accompany normal aging and CNS disease remain incompletely characterized.

    “The molecular correlates of normal aging and CNS disease are not fully defined.”

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.

A language model drew the claims from the paper on 2026-10-05, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-05 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
