Age-related changes in metabolite production in the gut correlate with the presence of beta-amyloid plaques in the brain, a hallmark of Alzheimer's disease.

An eye exam using artificial intelligence could detect Parkinson's disease (PD) earlier. This method using machine learning to classify PD based on changes in the retina vasculature of the eye.

Hyperbaric oxygen treatments (HBOT) in healthy aging adults increased telomere length of T-cells. HBOT lengthened telomeres by 38% and decreased the presence of senescent cells by 37%.

Researchers discovered differences between mildly and severely reactive astrocytes, which may explain why some people with Alzheimer's disease (AD) don't respond after amyloid plaques are removed.
