Gut Microbiome and Depression in Children: How Missing Amino Acids May Drive the Connection

by

TL;DR: Dysbiotic bacteria in depressed adolescents cannot synthesize lysine and tryptophan, starving the brain of amino acids needed for glutamate transport and serotonin production—a causative link proven by transplanting dysbiotic bacteria into healthy rats. Depression in adolescents has tripled in the past two decades. Most treatments target a single neurotransmitter—serotonin. But a landmark multi-omics study …

Genetics of Depression Linked to Gut Microbiome Abnormalities (2024 Study)

by

Alterations in the gut microbiome are causally linked to major depressive disorder (MDD), with certain gut bacteria either increasing or decreasing the risk of developing MDD. Highlights: Protective Bacteria: Ten gut bacterial taxa, including phylum Actinobacteria and family Bifidobacteriaceae, were found to be protective against MDD. Risk Factors: Ten other taxa, such as phyla Firmicutes …
