An Introduction to Possible Biomedical Causes and Treatments for Autism Spectrum Disorders Contributed by Marci Wheeler, continued
Some Biomedical Based Causal Theories of Autism Spectrum Disorders
There is no universally accepted theory of causation. It appears there is a complex interplay of factors that can result in symptoms leading to a diagnosis of an autism spectrum disorder. There is now believed to be a number of genetic and environmental causes. The purpose of this article is not to focus on genetic theories of causation. Here, the only focus will be on the most commonly cited biomedical concerns thought to be implicated. Later, the more commonly cited interventions which address these biomedical concerns will be shared.
Currently, there are four broad areas of focus which conceptualize the possible biomedical causes of autism spectrum disorders. Most researchers and practioners feel that all four areas are intertwined and that each affects the other. Gastrointestinal abnormalities, immune dysfunctions, detoxification abnormalities, and/or nutritional deficiencies or imbalances have all been suggested as potential biomedical “triggers” for autism spectrum disorders. It is hard to determine which scenario came first. It is felt that one problem is connected to the next that follows. But deciding which came first seems to be another part of the puzzle to address for each individual. Gastrointestinal abnormalities, immune dysfunctions, detoxification irregularities, and nutritional deficiencies or imbalances may cause some of the same symptoms. Often a problem in one of the four biomedical areas impacts one or more of the other areas. However, for purposes of simplification and clarity, each of these will be discussed separately.
