"There is now a large body of research underscoring the increased risk for individuals with a diagnosis of ASD to be suffering from immune dysregulation, allergies, food sensitivities, various gastrointestinal disorders, excessive oxidative stress, mitochondrial and metabolic dysfunction, autonomic disturbances, subclinical seizure activity and frank epilepsy. Research also shows that increased severity of many of these conditions correlates with increased severity of symptoms of ASD.
Treatment of comorbid medical conditions may result in a substantial improvement of quality of life both of the child and their parents. What investigations should be implemented can vary both within the autism spectrum and individually.”
