Autism causes are still a mystery however evidence is pointing to the fact that there are huge unexplained increases in incidence of autism ( over 287%) and that very often it happens in clusters i.e.
Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. Some people with ASD have a known difference, such as a genetic condition. There are likely multiple reasons, given the disorder's complexities and the fact that signs and severity differ.

This still remains controversial and continues to be studied. Babies may be born with a genetic vulnerability to autism that is then triggered by something in the external .

MMR vaccine was a popular theory concerning the causes of autism, many later studies failed to show a connection. The aim of this review is to summarize the key findings from genetic and epidemiological research, which show that autism is a complex disorder resulting from the combination of genetic and environmental factors. Again, most of the time, autism cannot be associated with a specific cause. This article uses the terms autism and ASD to denote classical autism and the wider dispersion of symptoms and manifestations of autism, respectively. Published monthly, JADD is committed to advancing the understanding of autism, including potential causes and prevalence (e.g., genetic, immunological, environmental); diagnosis advancements; and . Untreated Phenylketonuria. The Autism Intervention Research Network on Physical Health and Autism. We do know that autism is a neurobiological difference, meaning that the brain processes information differently for people with autism, than it does for people who do not have autism. Autism has no one single cause, both in terms of genes and the brain. Although there are many ongoing studies of what the causes of autism are, many are still inconclusive, and more studies have to be done. There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people. PKU. It certainly isn't because of bad parenting, and there are some hints that it is a genetically inherited problem, though this still has some speculation. During this time, try to avoid watching the news or scrolling on . CDC is working to find out how many children have ASDs, discover the risk factors, and raise awareness of the signs. The big debate (iii) that ranges in autism circles is about whether or not autism is a fixed, irreversible brain-based genetic disorder, or a systemic, reversible body-based biological condition that has identifiable causes, measurable abnormalities, and treatable dysfunctions. However, with increasing cases and increasing research, a few environmental, genetic, and biological risk factors have been identified.
