Summary
GLP-1 drugs may help prevent Alzheimer's early, Cox said, because they can alter the gut barrier, immune signaling and potentially act directly on the brain.
Parkinson's shows some of the strongest gut evidence: constipation can appear 20 years before onset, and misfolded alpha-synuclein may start in the gut and travel via the vagus nerve.
Breast milk also reflects gut-linked biology, Cox said, with morning milk carrying more cortisol and late-night milk more melatonin—differences that could help guide pumped-feeding schedules.
Vitamin B is another key microbiome output under study, as researchers sequence gut samples to identify what an individual's microbes are producing or lacking for more personalized treatment.
