A new observational study suggests that higher gut microbiome diversity may be associated with improved sleep quality and reduced nighttime awakenings in healthy adults.

Researchers analyzed stool samples and sleep tracking data from more than 1,200 participants over a six-month period. The findings showed correlations between specific bacterial strains and longer deep sleep cycles.

The study authors noted that diet, stress, and physical activity likely contribute to the relationship between microbiome balance and sleep regulation.

Further clinical trials are expected to explore whether targeted probiotics or dietary interventions could improve sleep outcomes.

Antibiotics before or after FMT raise C. diff relapse risk

A retrospective study of 124 patients treated with fecal microbiota transplantation for C. diff infection found that taking antibiotics for an unrelated reason, either before or after the transplant, roughly tripled the odds of the infection coming back. Overall, three in four patients improved within a week, but the findings point to a concrete step, limiting non essential antibiotics around the time of FMT, that could improve those odds further.

ADHD, Autism, Depression Gene Risk Shifts With Age

A Molecular Psychiatry analysis of the ALSPAC UK birth cohort finds that polygenic risk scores for ADHD, autism, and depression predict different peer, school/employment, and suicidality outcomes depending on whether you look in childhood, adolescence, or young adulthood. No gut-microbiome findings are involved.

Blueberries Alter Gut Genes Tied to Mood, Study Finds

A randomized, placebo-controlled pilot trial gave older adults with mild depression 2 cups of blueberries a day for 3 months. Mood scores didn't improve more than placebo, but gut-bacterial genes tied to GABA production shifted significantly, a preliminary but genuine gut-brain signal.
