Chronic subdural hematoma mapped onto the twelve hallmarks of aging: a proposed geroscience framework
This minireview proposes reframing chronic subdural hematoma as a geroscience disease by mapping its pathogenesis onto the twelve hallmarks of aging; chronic inflammation and altered intercellular communication have strong direct support, cellular senescence moderate evidence, and four hallmarks are essentially unstudied.

The key findings
The authors propose reframing chronic subdural hematoma as a geroscience disease by mapping its pathogenesis onto the twelve hallmarks of aging. [1]
Chronic inflammation and altered intercellular communication have strong direct support, while cellular senescence has moderate evidence and senescent cells have not been demonstrated in resected neomembrane tissue. [1]
Genomic instability, telomere attrition, epigenetic alterations and stem cell exhaustion are essentially unstudied in chronic subdural hematoma and framed as research priorities. [1]

Proposed mapping of CSDH onto twelve aging hallmarks
The authors describe chronic subdural hematoma (CSDH) as among the commonest cranial neurosurgical conditions of older adults and, based on incidence modeling, projected to become the most common cranial neurosurgical condition in adults by 2030. They note CSDH has not been formally examined through geroscience. Their minireview proposes reframing CSDH as a geroscience disease by mapping its pathogenesis onto the twelve hallmarks of aging described by López-Otín and colleagues. This is a proposed conceptual framework, not a validated model.

Strong, moderate and weak hallmark evidence in CSDH
Two hallmarks have strong direct support in the existing CSDH literature: chronic inflammation and altered intercellular communication, seen in the inflammaging fingerprint of hematoma fluid and dysregulated paracrine signaling of the outer neomembrane. Cellular senescence is called the most fertile moderate-evidence hallmark: the senescence-associated secretory phenotype overlaps with the cytokine, chemokine and matrix remodeling milieu of the CSDH cavity, but no study has yet demonstrated senescent cells in resected neomembrane tissue. Mitochondrial dysfunction, deregulated nutrient sensing and loss of proteostasis have weak inferential support.

Unstudied hallmarks and possible future gerotherapies
Four hallmarks – genomic instability, telomere attrition, epigenetic alterations and stem cell exhaustion – are essentially unstudied in CSDH and framed as research priorities. Disabled macroautophagy and dysbiosis have recently received initial direct measurements but remain only partially addressed. The authors note that the 2024 randomized trials of middle meningeal artery embolization, the success of atorvastatin in the ATOCH trial and emerging senolytic clinical translation collectively suggest CSDH may be a tractable target for future mechanism-directed gerotherapeutic interventions. The framework's stated aim is to specify which experiments would test it.

How to interpret this
This is an abstract of a minireview proposing a conceptual framework; the full text was not reviewed. The hallmark mapping is the authors' proposal, not a validated model, and the cited trial and senolytic evidence is presented as suggesting future directions, not as demonstrated benefit for CSDH.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
