Alzheimer's disease (AD) is one of the most common neurodegenerative disorders, characterized by the accumulation of Aβ and abnormal tau hyperphosphorylation. Despite substantial efforts in development of drugs targeting Aβ and tau pathologies, effective therapeutic strategies for AD remain elusive. Recent attention has been paid to the significant role of cellular senescence in AD progression. Mounting evidence suggests that interventions targeting cellular senescence hold promise in improving...

Older adults with Alzheimer's disease (AD), in addition to significant cognitive disability, have twice the risk of fracture compared to those with normal cognition. Fractures among older adults with AD are associated with substantial morbidity, loss of physical function, and significant mortality. Prior studies have shown a decreased risk of fracture among those taking acetylcholinesterase inhibitors, such as donepezil. With both cognitive and non-cognitive benefits, donepezil would be a...

CONCLUSION: Our findings emphasize significant connectivity alterations across all groups at both baseline and follow-up, with longitudinal analyses underscoring the progression of these changes. Graph theory metrics provide valuable insights into the transition from normal cognition to AD, potentially serving as biomarkers for disease progression.

Alzheimer's disease (AD), commonly known as senile dementia, is a neurodegenerative disease with insidious onset and gradually worsening course. The brain is particularly sensitive to senescence, and neuronal senescence is an important risk factor for the occurrence of AD. However, the exact pathogenesis between neuronal senescence and AD has not been fully elucidated so far. Neuronal senescence is characterized by the permanent arrest of the cell cycle, and the changes in its structure,...
