Article Response
This article was summed up pretty nicely by the title. Dr. Cryan and other scientists are in the early stages of relating microbes in our stomachs to a variety of influences on our bodies and our brains. Dr. Cryan said his idea was not well received initially which is unfortunate but somewhat understandable. The idea that something so tiny could potentially play a role in Alzheimer's disease, Parkinson's disease, Depression, Schizophrenia, Autism, etc is incredible.
Dr. Sisodia, a skeptic of Dr. Cryan, performed an experiment on mice where they were given antibiotics that would kill off most of the mice's bacteria in their guts. What they found in these Alzheimer prone mice was that their brains had far less of the protein clumps that are linked to dementia. Dr. Sisodia was surprised by the results.
However, this along with the other research discussed in the article does not prove cause and effect. Scientists do not want to give the impression that a cure for the aforementioned diseases is in the near future. Dr. Costa-Mattioli warns parents against going for store bought probiotics because only some strains of L. reuteri alter mice behavior. Much more research still needs to be done according to biologist Katarzyna B. Hooks, "We have the edges of the puzzle, and we're now trying to figure out what's in the picture itself."
