Life scientist John Rodakis started studying link between brains of unfit kids and gut microorganism after witnessing a marked improvement in health of his autistic son.

A course of antibiotic amoxicillin, which is typically prescribed for strep throat, helped in dramatic improvement in the 7-year-old son of Rodakis.

Shortly, after completion of the course, John and his wife observed a number of positive changes in their child's health.

Rodakis reported that their son started making eye contact, his speech improved a lot and his energy level also increased to a great extent.

His son also started to make some amendments in his routine. Previously he used to avoid all such behaviors, he said.

Soon after seeing these changes Rodakis tried to determine the reason behind it. And after deep study, he found that the effect of medication on the gut bacteria is responsible for these behavioral changes.

These findings further inspired Rodakis to start studying the link between the gut bacteria and autistic spectrum disorder (ASD).

Although, Rodakis does not advocate the use of antibiotics for the treatment of autism, but he aims to analyze as to why some kids show improvements after taking antibiotics.

He further said that parents of kids suffering from any such illness must not immediately rush for medication until and unless they have sufficient proofs available.

The findings made by Rodakis were published in Microbial Ecology in Health and Disease.

Rodakis and his team revealed that some parents have noticed worsening of autistic children's behavior after taking antibiotics and this led them to the conclusion that antibiotics interact with autism.

However, several other parents have also observed improvements in children with ASD symptoms after taking antibiotics, due to which they continue to give their children antibiotics on a regular basis to improve their condition.
