Germs in Your Gut Are Talking to Your Brain. Scientists Want to Know What They're Saying.
[...] The scientists eventually discovered changes in the brains of these antisocial mice. One region, called the amygdala, is important for processing social emotions. In germ-free mice, the neurons in the amygdala make unusual sets of proteins, changing the connections they make with other cells.
Studies of humans revealed some surprising patterns, too. Children with autism have unusual patterns of microbial species in their stool. Differences in the gut bacteria of people with a host of other brain-based conditions also have been reported.
But none of these associations proves cause and effect. Finding an unusual microbiome in people with Alzheimer's doesn't mean that the bacteria drive the disease. It could be the reverse: People with Alzheimer's disease often change their eating habits, for example, and that switch might favor different species of gut microbes.
Fecal transplants can help pin down these links. In his research on Alzheimer's, Dr. Sisodia and his colleagues transferred stool from ordinary mice into the mice they had treated with antibiotics. Once their microbiomes were restored, the antibiotic-treated mice started developing protein clumps again.

Vaccines cause autism. This bullshit is just drawing the fire with fad medicine.
