- Wellcome Leap's FORM is a $50 million program investigating links between the early-life gut microbiome and neurodevelopmental challenges, including autism with high support needs.
- Washington University researchers found markedly different gut microbiomes in people at the earliest preclinical stages of Alzheimer's, with differences correlated to amyloid and tau accumulation before any cognitive symptoms appeared.
- Scientists at NYU and Rutgers have proposed that early antibiotic exposure may initiate a cascade contributing to Alzheimer's decades later, though causation is not established.
- Cesarean birth, antibiotic use, formula feeding, and maternal BMI are among modern medical and food system variables that can disrupt the developing gut microbiome, contributing to neurodevelopmental differences.
- Worldwide brain disorder spending reaches $1.7 trillion annually, with nearly all of it going to people already in crisis, past the point where underlying biology could be redirected.
- US neurodevelopmental screening typically begins between 9 and 30 months, and providers rarely diagnose autism or neurodevelopmental delay before ages 3 to 6 — well after the developmental window the authors say matters most.
Why it matters: Of the $1.7 trillion spent annually on brain disorders, nearly all goes to people already in crisis — past the developmental window where the underlying biology could have been redirected. The authors' most concrete ask, connecting maternal and infant clinical care around the gut-brain axis, is a structural change with a near-term implementation path.
