Researchers from Arizona State University have revealed that fecal transplants have drastically reduced autism-related symptoms in children with autism spectrum disorder (TEA) over a period of two years. The participants in the study experienced improvements in their bowel health, as well as, highlighting the possible benefits, fecal transplants can offer individuals affected by autism spectrum disorder.
The results were revealed in a recently published study detailing the long-term effects of Microbiota Transfer Therapy (MTT, a form of fecal transplantation) on the symptoms of autistic spectrum disorder. According to a university announcement, parents reported a "slow and steady reduction" of these symptoms in the next two years.
During the two years after treatment, an expert appraiser determined that there was a 45 percent fall in the symptoms of the core spectrum disorder, which included the categories of behavior, language and social interaction. This determination was made by comparing post-treatment symptoms with pre-treatment symptoms.
Rosa Krajmalnik-Brown, doctor, one of the researchers behind the study, explained:
We are finding a very strong connection between the microbes that live in our intestines and the signals that travel to the brain … Many children with autism have gastrointestinal problems and some studies, including ours, have found that these children also have the worst symptoms associated with autism . In many cases, when you are able to treat these gastrointestinal problems, it improves your behavior.
Gastrointestinal problems affect between 30% and 50% of people with autism. Unlike previous investigations that only found short-term improvements in ASD symptoms and intestinal health through the use of an antibiotic, the latter study noted benefits that increased and persisted for two years after treatment. Fecal transplants have previously been associated with a reduced body weight in overweight individuals.
