Early-Life Adversity Predicts Markers of Aging-Related Neuroinflammation, Neurodegeneration, and Cognitive Impairment in Women.

Objective: Despite the overwhelming evidence for profound and longstanding effects of early-life stress (ELS) on inflammation, brain structure, and molecular aging, its impact on human brain aging and risk for neurodegenerative disease is poorly understood. We examined the impact of ELS severity in interaction with age on blood-based markers of neuroinflammation and neurodegeneration, brain volumes, and cognitive function in middle-aged women.

Methods: We recruited 179 women (aged 30-60 years) with and without ELS exposure before the onset of puberty.

Spermidine reduces neuroinflammation and soluble amyloid beta in an Alzheimer's disease mouse model.

Background: Deposition of amyloid beta (Aβ) and hyperphosphorylated tau along with glial cell-mediated neuroinflammation are prominent pathogenic hallmarks of Alzheimer's disease (AD). In recent years, impairment of autophagy has been identified as another important feature contributing to AD progression. Therefore, the potential of the autophagy activator spermidine, a small body-endogenous polyamine often used as dietary supplement, was assessed on Aβ pathology and glial cell-mediated neuroinflammation.
