Another episode of "It's all in the Gut"

Bacterium can reverse autism-like behaviour in mice
Doses of a human gut microbe helped to reverse behavioural problems in mice with autism-like symptoms, researchers report today in Cell1. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
Applying this to humans might be a little tricky, although I wonder if you could really do much harm by just trying introducing different bacteria until you find one that helps:
Although many anecdotal reports and small studies have suggested that ‘probiotic’ bacteria, such as those found in yoghurt, and antibiotics can help with the symptoms of autism, Cryan says more research needs to be done. Because there are a number of types of autism in humans, it will be important to look at how different symptoms might be affected by different microbes. Another question is whether the microbiomes of the mice — whose symptoms result from maternal infection — differ from those of mice that are genetically predisposed to autism-like symptoms, Cryan adds.
Here's the main point, though:
“I think there is now sufficient proof of concept where people can start to look at probiotic bacteria to improve brain function in humans,” says gastroenterologist Stephen Collins of McMaster University in Ontario, Canada. 
Maybe Freud should have worked with the Kellogg brothers.  (Although, now that I check, they had some freaky ideas about matters sexual such that they might have been a bad influence even on Sigmund.)

Not possible, Freud was one sick puppy in that regard. :)
