Autism spectrum disorder is not a single disorder, it comprises of a very diverse group of neurodevelopmental disorders. According to the Diagnostic and statistical manual of mental disorder 5th edition (DSM-V), diagnosis of ASDs includes three main deficits which are; having difficulties with social interaction and communication and deficit in behaviour, for example individual with ASD tend to repeat the same behaviour and they tend to be preoccupied. Under the DSM- V ASD consist of Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS) and childhood disintegrative. This essay will discuss the Etiology and prevalence of ASD as well as the treatments and interventions for ASD. Research study findings will be used as evidence to support the efficacy of these treatments for ASD. Finally this essay will briefly consider some limitations of these treatments. Several empirical researches suggest that ASD is heritable and that genetic component is the key factor involved in vulnerability to ASD; most of this evidence comes from twins and family studies. Silverman et al (2002) supports the claim that ASD is genetically determined. They found that ASD was present in multiple cases within extended families. Similarly, researchers have shown that ASD is linked with several genes, such as GABRA4, GABRA2, GABRA3 etc. Ma et al., (2005), provides support for this claim, they found that GABRA4, GABRR2, GABRA2 and GABRB1 are all linked to ASD.Show MoreRelatedAutism Spectrum Disorder ( Asd ) Essay1386 Words   |  6 PagesAutism Spectrum Disorder (ASD) refers to a group of neurodevelopmental disorders characterized by impairments in social interaction and communication, as well as behaviors (e.g. movements, interests and activities) that are restricted and repetitive1,2.

It is often perceived that Autism Spectrum Disorder is not common; however, this is not true. In 2011, some of the more recent epidemiological studies found ASD prevalence of approximately 86–91 per 10,000 in the United States alone (Zaroff Uhm, 2011). This number has only continued to rise over the past four years as this disorder continues to afflict about 1 in 50 children (Butcher, Hooley Mineka, 2014).

The prevalence of ASDs is on the rise, and yet, no effective treatments exist. The US Centers for Disease Control and Prevention (CDC) reported that 1 in 68 children at 8 years of age had ASDs in 2014, up 220% since 2002.

There are two main theories that attempt to explain this gender disparity: the extreme male brain theory, which is supported by research on fetal testosterone, X-chromosomes, Y-chromosomes, and the female protective effect; and the biased diagnostic criteria theory, which is also supported by many research studies that explore phenotypic differences in the symptoms of boys and girls with ASD. Ultimately,Read MoreAutism Spectrum Disorder1278 Words   |  5 Pagesthat genetic factors are playing key role in the prevalence of ASD. To begin with, U.S. Department of Health and Human Services, Centers for Disease Control and Prevention (CDC) published the relationship between the number of autistic boys and girls. The statistical evidence shows that boys are more inclined to become autistic than girls. CDC states that 1 in 42 boys and 1 in 18 9 girls were identified as having ASD. This observation shows that ASD is likely a sex-linked inheritance. Sex-liked inheritanceRead MoreIs Autism A Developmental Disorder? Essay1619 Words   |  7 Pagesseverity of the case.
