Do environmental factors play a role in the onset of autism? Although the concept and onset of autism is complex, with both hereditary and external factors, it is evident through several researchers that a person's immune system plays an important role in the onset of autism. Some of the elements that influence the immune health of the autistic person are linked to the prenatal and postnatal environment in which they live, in particular their regular food intake. These factors combine to increase a child's risk of autism. Although it is complicated and difficult to deduce the causes of autism, it is important to understand that in addition to genetic factors, several environmental aspects are also involved in the cause of autism. However, proper and timely diagnosis is important for a child's well-being, so it is important to know about environmental factors and prevention. Autism: Autism is a composite neurodevelopmental disorder described as impaired social interaction, communication discrepancies, limited activities, and repetitive interactive acts. These features extend from mild to severe cases and are likely complemented by cognitive impairment and associated comorbidities. Autism spectrum disorder (ASD), as classified by researchers and health professionals, includes three types of disorders: first autistic disorder, then Asperger's disorder and pervasive developmental disorder - not otherwise specified. Furthermore, there is no indication that these three types also possess any particular homogeneity (Daniels). In simpler terms, “people with ASD process information in their brain differently than others” (Centers for Disease Control and Prevention). A quantity of social and behavioral symptoms...... middle of paper ......capable of giving birth to autistic children. However, whether the father is the other parent does not matter much in this concept. However, research claims that having either parent work more can affect the child's neurological development in negative ways. In conclusion, an effort is needed, either on an individual or joint basis, to reduce the likely environmental factors, mainly toxic. At the government level, it is important to reassess national regulations regarding the control of toxic substances and pollution. Through this, food packaging companies, factories and the use of electronic machinery can be regulated and held accountable in the event of a major problem in the country. At the non-governmental level, social activists, in cooperation with medical and psychological research, must raise public awareness of the health risks for future generations...
