Changes in salivary brain-derived neurotrophic factor following a standardized eating task in community-dwelling older adults: a cross-sectional study.

Association Between Serum BDNF and S100 B Levels in Community-Dwelling Older Adults.

The inverse relationship between BDNF and S100 B suggests a link between neurotrophic and neuroinflammatory processes and nursing interventions that enhance BDNF may also affect S100 B level, which may foster brain health in older adults.

Afternoon salivary cortisol shows no association with same-day state anxiety in community-dwelling older adults during the COVID-19 pandemic

A single afternoon salivary cortisol measurement was not associated with same-day state anxiety in community-dwelling older adults in Japan during the COVID-19 pandemic, and this null finding should be interpreted in the context of the present study design and measurement approach.

Exercise-induced changes in serum and plasma BDNF levels in neurological disorders: a systematic review and meta-analysis of key moderating factors

Exercise is associated with significant BDNF increases in neurological populations with MS and PD, particularly with longer sessions and combined training, and findings should be considered hypothesis-generating.

Association between occlusal support, salivary amyloid-β42 levels, and cognitive function in older adults: A cross-sectional pilot study

The findings support the potential role of salivary Aβ 42 as a non-invasive extracerebral biomarker of neurodegenerative disease, such as Alzheimer's disease, such as Alzheimer's disease.

Serum Brain-Derived Neurotrophic Factor Across the Human Lifespan: A Systematic Review and Meta-Analysis

Effects of a Nutritionally Balanced Between-Meal Food Product on Brain Function in Older Adults: Protocol for a Randomized Controlled Trial (the MiniMeal Study).

BACKGROUND Increasing evidence suggests that diet influences gut microbiota composition and systemic inflammation, which in turn may affect brain health, cognitive function, and mood regulation. Elevated levels of systemic inflammation have been associated with reduced resting-state functional connectivity within the d...
