The scientists revealed that there is a strong possibility that the immunologic disruptions may have processes beginning early in life, which can go on to influence brain development and social functioning, leading to the development of ASD.
The study revealed that 11.25 percent of children reportedly diagnosed with ASD have a food allergy, which was significantly higher than the 4.25 percent of children who are not diagnosed with ASD and have a food allergy.
The researchers said that the study was observational. The findings did not delve into the causality of this relationship. But there are many studies in the past that have pointed to possible links --increased production of antibodies, immune system overreactions causing impaired brain function, neurodevelopmental abnormalities, and alterations in the gut biome.
The researchers said that the connection calls for further examining. It was also revealed that it is difficult to tell which comes first, food allergy or ASD, which calls for another longitudinal study.
