The Etiology of Intellectual Disabilities and Autism

Genetics seems to be an important factor, as the blood telling rate for the core syndrome falls at about 5% spell the autism spectrum disorder is probably around Twin studies receive shown concordance order of 60-89% in minimization twins and under 5% in lordly twins, which suggests a heritability of close to 100% in shells that bent affiliated with specific medical exam disorders(Gilbert). Some aberrant or variant genes may yet be implicated, examples including neurologist and glutamate genes(Gilbert). It is likely that there is a large mount of genes, to a greater extent than 30, involved in the increase of susceptibility for autism spectrum disorders(Gilbert). T is now know that defined mutations, genetic syndromes, and De novo copy number variations (primarily deletions) make up 10-20% of Autism Spectrum Disorders(l_cavalier). proportional portions of the brain are also often dysfunctional in autism and abnormalities in the in the magical and cerebellum are often present (Gilbert). In addition, unchallengeable is over-represented in autism, more specifically in those with IIS succeeding 70(Glibber). Other abnormalities entangle hyp other(a)mias in the blood, dopamine and endorphin dysfunction, and excess of gall fritillary acidic protein in the cerebrations fluid(Gibber).Without any(prenominal) cognize genetic predisposition certain acquired brain lesions potentiometer gain autism, although some studies indicate interaction with autism susceptibility genes may be occurring. It is thorny to say what can be done to prevent autism(Gilbert). No known drugs are known to have a substantial effect on the resultant role of autism and despite what Jenny McCarthy pushes, vaccinations do not cause autism. Until the causes of autism are discovered it is unlikely we will ever know for a certainty how to prevent it. community with autism are often no st passr to neurophysiology deficits, more specifically executive function deficits. Some of these executi ve function deficits include suffering planning ability, unkept motivational level, clog with snip concepts, difficulty maintaining, difficulties with empathy, difficulty grasping the theory of mind, decreased drive for central coherence(Gilbert). People given a diagnosis of childhood autism also fall into the low range of IQ, at below 80(Glibber). Those with Speakers Syndrome usually boast an IQ above that typically seen in autism, usually above 70(Glibber).The etiology of mind balk is also difficult to pinpoint, due to the fact that in approximately half the cases of quick-witted balk the cause is unknown (McDermott). The etiology is defined as a multicultural construct composed of four categories of risk factors biomedical, social, behavioural and fosterageal, that exist across time, including the across the life of the various(prenominal) and across generations from erect to Genetic actors such as those associated with Down Syndrome can be super associated but not necessarily viewed as casual (McDermott).Algorithms have been suggested for the military rank of the individuals relying on family history, physical findings, and neurological functioning (McDermott). Some diagnostic techniques include chromosome micro-dissection, fluorescence in situ habitations and more. Other potential causes include telemetric rearrangements/chromosomal anomalies for different forms of intellect disabilities (often Down Syndrome), tourism in 95% of the cases of DownSyndrome, mutations in sex-linked individual(a) genes in Fragile X/Williams Syndrome/ Parade-Will Syndrome, neural tube defects in spinal biffed, dealer trauma later in life, and many (McDermott). Mothers and cuttingborns should avoid infections, head trauma, harmful chemical and compounds, alcohol, environmental chemicals and food/drink deprivation in order to prevent intellectual impairment(McDermott). Beyond this, much about intellectual disability is unknown and thus, is hard to prevent. 2 . Discuss the role of IQ and accommodative demeanor in both intellectual capabilities and autism.Two defining characteristics of autism and intellectual disability are deficits in IQ (not in Espaliers however) and accommodative behavior. The PAP describes adaptative behavior in terms of individual performance in relation to person environment interactions and includes it with social skills and peer acceptance as a component Of social competence(Forthwith-Duffy). Usually, the common definition of mental retardation implies that comprehension and adaptive behavior are distinct and not overlapping constructs(Forthwith- Duffy).Three dimensions of adaptive behavior are expressed by observable, practical, conceptual and social skills(Forthwith-Duffy). For kinda some time IQ was the only criterion given comity in intellectual disability diagnosis(Forthwith-Duffy). Studies have lay outd that individuals with both intellectual disability and autism demonstrate significantly more impa irments in adaptive behavior as opposed to someone with just one(Lacerative).Individuals with Autism Spectrum Disorders and those with intellectual disabilities seem to demonstrate different adaptive behavior profiles. Those with intellectual disability demonstrated a flat profile, indicating consistent scores(Lacerative). The autistic groups (verbal and non- verbal respectively), however, had a more abrupt score (meaning more variance) with the non verbal group scoring lowest in intercourse and the verbal group scoring lowest in colonization(l_cavalier). accommodative behavior scales often undertake adaptive behavior and maladaptive behavior.In the be 20 years there have been many developments in unsymmetrically valid adaptive behavior scales, some boasting a reliableness of . 90(Forthwith-Duffy). Adaptive behavior is Often defined in terms Of its kindred to cultural expectations and environment. A succinct way of delineating the differences between IQ and adaptive behavior i s defining an cognition test as something that measures performance or what an individual can do and adaptive behavior scales report what an individual does Duffy).Four categories of intellectual disability are named depending on IQ score. With an IQ of 55-69 the designation is mild, with an IQ of 40-54 the designation is moderate, with an IQ of 25-39 the designation is wicked and tit an IQ below 25 the designation is unfortunately, public train data on intellectual disability is unreliable due to intelligence tests not be administered universally (McDermott). It has been recognized for quite some time that an IQ of above 70 is one of the strongest predictors of a good outcome in autism.Individuals who have autism and an IQ of under 70 usually have to attend specialist autism classrooms. People given a diagnosis of childhood autism also tend to end up in the low range of IQ, at below 80(Gilbert). Those with Speakers Syndrome usually have a Geiger IQ than that typically seen in a utism, usually above 70(Gilbert). As I noted ahead there IQ often determines their classroom environment which determines part of their habits of colonization. In put forward (2004), the author replies to queries by lava. N. Years about various 3. spectacles of the education of children with autism and developmental disabilities. In his responses, inferences to constitutional principles, core principles, and public indemnity can be drawn. What are the constitutional principles, core principles and public policies that aptitude be connect to the Bear 2004) replies to the layovers? Describe and explain how they are related to the educational issues discussed in the letters. Beginning in the asses, the disability-rights revolution introduced a new era of public policy, core principles and constitutional principles(Turnbuckle).PARA v. Commonwealth of Pennsylvania and mill v. D. C. Board of Education guaranteed a right to education. Next, came Wyatt v. Stickiness which guaranteed a right to treatment(Turnbuckle). These threesome cases would prove to be landmarks in the disability-rights revolution, influencing decisions to this very day. This is demonstrated by Donald Bear nicely. According to the Individuals with Disabilities Education Act every child with a disability is promised a free and appropriate public education(Bear 2005).As the most canvas and best refined method of teaching for Autism, Applied Behavior outline should be indebted to the individual by his constitutional rights. ABA has has 1 intumesce controlled clinical trial as well as 4 other controlled trials. This is combined with the 500 or so studies that have been done on ABA 200 of which had a convincing experimental design(Bear 2005). ABA is the only theology that can promise Autistic persons an approximately 50% chance for an independent bounteous life(Bear 2005). Unfortunately, very few U.S centers offer effective ABA to children with autism with adequate federal or state agency fund ing(Bear 2005). In accordance with the Board of Education v. Rowley case which guaranteed disabled individuals the right to a free, appropriate secern and beneficial education in the least restrictive environment, ABA should be offered at all take with students who are disabled(Turning). In ABA the highest priority is communication skills allowed by social skills, followed by self-care skills and finally, followed by intellectual skills.This order is rarely followed in schools without ABA- The effectiveness of ABA depends on analysis and thus, teachers with minimal training are thereby inadequate(Bear 2005). When individuals are guaranteed an individualized and beneficial education it is more than implied that they receive the most efficacious treatment, which in this case is ABA. Applied Behavior Analysts have been developing language and communication skills in children with severe developmental delays for over 30 years(Bear 2005).
