Allostasis links white matter hyperintensities with age‐related human brain structure and function: evidence from EEG and structural MRI.
Abstract
The human brain integrity relies on the synergistic interplay between neural activity and supporting vascular and metabolic processes throughout life. This relationship, ruled by allostatic mechanisms, regulates brain architecture and activity. White matter hyperintensities (WMH) serve as indicators of the vascular impact on brain structure. While the strong association between vascular/metabolic systems and brain structure/function is established, the precise mechanisms linking allostasis to WMH remain elusive. We hypothesized that allostasis influences white matter through neuroinflammatory mechanisms, and WMH mediate neuroinflammatory effects on EEG measures.

Research summary
The paper explores the relationship between allostasis, white matter hyperintensities, and brain structure/function, which are relevant to understanding the aging process and its impact on brain health. However, while it addresses mechanisms that could be linked to age-related changes, the focus on neuroinflammatory effects and WMH does not directly tackle the root causes of aging or lifespan extension. Thus, it represents solid research but with limited impact on the broader field of longevity.
