Changes in β-amyloid (Aβ) and hyperphosphorylated tau (T) in brain and cerebrospinal fluid (CSF) precede Alzheimer's disease (AD) symptoms, making the CSF proteome a potential avenue to understand disease pathophysiology and facilitate reliable diagnostics and therapies. Using the AT framework and a three-stage study design (discovery, replication, and meta-analysis), we identified 2,173 analytes (2,029 unique proteins) dysregulated in AD. Of these, 865 (43%) were previously reported, and 1,164 (57%) are novel.

The article discusses the role of gut dysbiosis, bacterial amyloids, and metabolic diseases in the development and progression of Alzheimer's disease (AD). It highlights the bidirectional relationship between the gut microbiome, inflammation, and metabolic disorders, and how these interconnected pathways contribute to neurodegeneration. The review explores potential therapeutic strategies targeting the gut-brain-metabolic axis to mitigate AD progression.

This systematic review examined the relationship between cognition and motor speech production in healthy older adults and those with mild cognitive impairment, analyzing 22 studies with 747 participants. Findings suggest that cognitive functions, particularly attention and executive abilities, are linked to motor speech performance, though evidence quality varies and gaps remain.

The article examines the relationship between falls, chronic pain, and frailty among middle-aged and older adults in Yunnan Province, China, with a focus on ethnic minority populations.
