Mental Health May Depend on Creatures in the Gut
The microbiome may yield a new class of psychobiotics for the treatment of anxiety, depression and other mood disorders
Scientific American has an interesting article by Charles Schmidt about the gut microbiome interaction with the brain and its connection to autism and mood disorders:
"Scientists are increasingly convinced that the vast assemblage of microfauna in our intestines may have a major impact on our state of mind. The gut-brain axis seems to be bidirectional—the brain acts on gastrointestinal and immune functions that help to shape the gut's microbial makeup, and gut microbes make neuroactive compounds, including neurotransmitters and metabolites that also act on the brain."
