Literature Review on Autism Spectrum Disorders Essay
AbstractAutism has become an increasing font of interest, e circumscribedly to enquiryers and health check professionals. This ontogenesis in interest is nearly presumable due to the fact that autism is becoming an increasing problem in baberen, with the physique of key outs doubling in just a four year period. In order to discover what whitethorn cause this distract as substantially as finding effective ways to treat it, people must(prenominal) be informed and knowledgeable more or less autism. The current field of operation discusses what ASD is, symptoms of this unhinge, mathematical causes and peril factors, and modes of preachings and therapy, much(prenominal) as early handling and sensational desegregation therapy. This teach hypothesizes that sensational(a)(a) consolidation therapy lead signifi outhousetly improve grades and cultivate performance in pip-squeakren with autism.Recently, it seems as if autism spectrum derangement (ASD) has been rec eiving a great come up to of attention by those who work in the medical field, researchers, education providers, and p bents as well. This is due to the fact that the number of diagnoses has increased significantly. In just a four year period, the number of recorded diagnoses for these causes of disorders has doubled (Keen & Ward, 2004). This substantial increase in the diagnoses of ASDs could be due to the fact that doctors and early(a)wise health professionals are becoming more than than aware of the criteria for these disorders, and are causening to open great recognition of ASD in more able, high functioning squirtren. In the past, thither create been several cases where high functioning tiddlerren were first diagnosed with ADHD, and later accepted an ASD diagnoses (Keen & Ward, 2004). With the recent awareness of autism spectrum disorders, a more clear criteria has developed for the diagnoses of these disorders.In broad terms, autism spectrum disorders is a group o f developmental brain disorders, collectively called ASD. It is called autism spectrum disorder because the symptoms and levels of impairment for these disorders rangeswidely in each individual with an ASD. ( guinea pig Institute of psychogenic health NIMH, 2011). In fact, according to the discipline Institute of affable Health (NIMH, 2011), whatsoever higher functioning shaverren may only be softly impaired by his or hers symptoms, while other barbarianren who are grim functioning may gull more everlasting(a)ly impaired by his or hers symptoms, causing them to be severely disabled.To diagnose an individual with ASD, unit of measurementy must meet the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR). Currently, there are phoebe bird defined disorders that lessen under the category of ASD. These disorders acknowledge autistic disorder (classic autism), Aspergers disorder (Aspergers syndrome), perv asive developmental disorder non otherwise specified (PDD-NOS), Retts disorder (Retts syndrome), and childhood clastic disorder (CDD) (NIMH, 2011). However, this review will focus mostly on the more common disorders, classic autism and Aspergers syndrome. The NIMH (2011) has identified some key symptoms seen in individuals with ASD. plot symptoms do vary from genius child to the next, the symptoms tend to fall into tether main areas. These common chord areas take well-disposed impairment, talk difficulties, and insistent and stereotyped doingss.Children with autism have trouble with mixer interactions and find it difficult to contract in ein truth daylight social interactions. Some of these problems with social interactions may include having trouble with making eye achieve, have trouble listening to and responding to other people in their environment, and having trouble picking up on social cues and reading peoples emotions. Children with ASD may respond unusually or inappropriately when others express feelings of anger, sadness, distress, or affection (Kamps, Leonard, Vernon, Dugan, & Delquadri, 1992). Children with autism also suffer from several communication issues, such(prenominal) as failing or being slow to respond to communicative attempts to get their attention, developing langu mount up at a slower one thousand than others, repeating words or phrases that they hear, and using words that are eerie or out of bewilder, that do not really make sense experience to people other than the child and those close to the child whom are beaten(prenominal) with the childs communication style. The last important symptom seen in childrenwith ASD is repetitive and stereotyped behavior.Many children with ASD tend to have odd, repetitive actions and behaviors that may be referred to as stereotyped behaviors. An example of a stereotyped behavior might be a simple gesture of the arm that is repeatedly through with(p) by the child. Children with a utism often have one battleground or interest that they tend to overly focus on. They tend to become preoccupy with one particular subject, and will learn everything they can about the subject of interest. Because autistic children seem to display several repetitive behaviors and thoughts, a entrap routine is usually the best environment for a child with ASD (NIMH, 2011).While there have been many theories and suggestions of what may cause autism spectrum disorders, there is not one particular known cause of these disorders. A great bear of research has been done to examine possible causes of and lay on the line factors for this disorder. Recently, there has been research on the hypotheses that enate early life factors associated with hormone levels may have some correlation with being at risk of having a child with ASD. Ascherio, Lyall, Pauls, Santangelo, and Spiegelman (2011) conducted a piece of work to see if they could find any familys between current maternal early li fe factors associated with hormone levels and the risk of having a child with an ASD. This composition focuses on maternal early life factors, and how some of these reproductive and hormonal factors of mothers could put them at risk of having a child with ASD (Ascherio, Lyall, Pauls, Santangelo, & Spiegelman, 2011). The methods of this study include a cohort study with 61,596 women.Data was collected from these women, which included age of menarche (first menstrual cycle), characteristics of menstrual cycle during adolescence, use of parturition control, specifically oral contraceptives, prior(prenominal) to have given birth, body shape, and body big money index (BMI). The results of this study showed relationships between higher BMIs at age 18, early age at menarche, and longer use of oral contraceptives prior to first birth, and being at risk for having a child with ASD (Ascherio et al., 2011). distinct risk factors for having a child with an ASD that have been studied inclu de antenatal, or the period of time before the child is born, perinatal, or the period of speech communication and immediately before and after lurch, and parental, or characteristics of the parents, factors. In a study done byHertz-Piccottio et al. (2010), the authors examine possible parental, prenatal and perinatal factors associated with ASD. The methods of this study was a case-control study, using a cohort of children in mainland China. examples came from six special education shallows and two Pre initiate Autistic Children Special Education Institutions in Tianjin, China (Hertz-Piccottio et al., 2010). The parental risk factors that were studied included parental ages at delivery, ethnicity, occupation, education, man and wife of a close relative, exposure to toxins, personality, and family medical history of different illnesses (Hertz-Piccottio et al., 2010, p. 1313).The prenatal risk factors that were examined in this study included maternal characteristics and behavi ors during pregnancy, alcohol consumption, hummer and second hand smoke exposure, exposure to X-rays, attempt to terminate pregnancy, contact with toxins, emotional state, disease history, and medication history (Hertz-Piccottio et al., 2010, p. 1313). Some perinatal factors that were examined include infant gestational age at birth, fetal nuchal reconcile (umbilical chord wrapped around neck), cesarean delivery, and breech birth. Also included were immature complications such as birth weight, delayed crying, and abnormal skin comment due to an array of conditions such a hypoxia, apnoea, neonatal jaundice, and several other conditions (Hertz-Piccottio et al., 2010, p. 1313). The results of this study showed relationships between several of the factors examined and the risk of having a child with ASD. In relation to the prenatal risk factors studied, seven conditions during gestation were significantly associated with the risk of having a child with ASD, four of which showed the strongest relationship. The four prenatal risk factors that showed the strongest relationship included frequent maternal second-hand smoke exposure, chronic and acute medical conditions unrelated to pregnancy, maternal unhappy emotional state, and one or more gestational complications (Hertz-Piccottio et al., 2010, p. 1314).For the perinatal risk factors that were studied, seven characteristics at the time of delivery were significantly associated with autism. These characteristics include abnormal gestational age, including preterm and post-term, nuchal chord, cesarean delivery, delayed crying, newborn infant complications, apnoea, and neonatal jaundice (Hertz-Piccottio et al., 2010, p. 1314). For the parental characteristics studied, results showed that gravidity 1 and advanced maternal(p) age at delivery weresignificantly associated with autism (Hertz-Piccottio et al., 2010, p. 1314).Other studies have also done research on possible perinatal, prenatal, and parental risk facto rs for autism. In a study done by Agerbo et al. (2005), the authors created a study in Denmark of children with ASD. This study focused on possible perinatal risk factors for autism, as well as the associations between parental psychiatrical history and socioeconomic status and the risk of having a child with autism. The following perinatal factors were investigated in this study birth weight, gestational at birth, weight for gestational age, birth weight, Apgar score at 5 minutes, fetal presentation, mode of delivery, pregnancy characteristics such as multiple gestation, and parental characteristics such as maternal smoking, maternal and paternal ages, maternal citizenship, and number of previous pregnancies. Other factors considered were parental psychiatric history, that is, if the parent had been diagnosed with a psychiatric disorder prior to the date the child was diagnosed with autism, and socioeconomic factors, including maternal education and parental wealth (Agerbo et al., 2005).As we begin to understand more about what exactly autism spectrum disorders are, what may cause these disorders, and how to diagnose children more accurately and sooner, the next step in being proactive with ASD is studying different treatment methods and developing new methods of treatment that may be more effective. The biggest impairment for most children with ASD is the social impairments caused by these disorders. maturation treatments that may attend children with an ASD learn how to better interact in social situations could possibly be the most useful type of treatment for these children.Researchers have been working on several different treatment methods for children with autism, especially treatments to befriend develop and improve social skills. In a study done by Koegel, Koegel, Hurley, and Frea (1992), the authors seek out to find a treatment to improve social skills in children with an ASD. This study assessed whether self-management could be used as a profic iency to improve extended responsiveness to verbal initiations from others, without the presence of a treatment provider. The methods of this study included four children, all of whom were diagnosed with autism.The results of the study showed that children with autism who displayed severe deficits in social skills could learn to self-manage responsivity to others in multiple community settings (Koegel, Koegel, Hurley, & Frea, 1992). another(prenominal) method of treatment that is being explored is the use of social robots for the therapy of children with ASD. In a study done by Werry, Dautenhahn, Ogden, and Harwin (2001), the researchers developed a robotic agent that could help with therapy in children with autism. This study was called the AURORA project, which started in 1998. The results so far have been quite promising, and the social robot has prove to be a very useful tool for children with autism. It gives them the opportunity to course seance social interactions and serv es as a social go-between (Werry, Dautenhan, Ogden, & Harwin, 2001).The treatment of autism is not a simple process. in that location is no single therapy or method of treatment that can completely cure an individual with autism. However, there are an assortment of treatments and therapies that have proven to be effective in treating children with autism. Quite often, children with autism combine different treatment methods and therapies to improve different skills. Some of the more common begines at treating autism in children include behavioural procedures, such as early intercession and trenchant mental testing trainings, speech therapy, dietary approaches, and occupational therapy ( Watling, Deitz, Kanny, & McLaughlin, 1999).Early intervention, a behavioral analytic treatment for autism, is an intensive behavioral therapy that is started as soon as a child is diagnosed with autism, usually before age 5. This type of therapy is found on the principles of operant conditioni ng. In this type of treatment, therapists simplify childrens environment in order to maximize successes and minimize failures. For example, the therapist might collapse a behavior down into smaller units and teach each unit individually, eventually linking all of the units together, which may also be called chaining. Another method of simplification that a therapist may use is discrete trial format. Discrete trial format involves a one on one interaction with a therapist that is carefully planned out, in which the child receives short and clear instructions from the therapist, and is immediately reinforced for every jog response.Another type of treatment for children with autism that is becoming more popular is occupational therapy. Occupational therapists are trained in teaching every day skills to help the individual being treated live as one by one as possible. These skills can be very helpful to children with an ASD. One of the most well-known types of therapy occupational the rapists use to help treat autism is sensorial combine therapy. Those who practice this type of therapy hypothesize that the primary symptoms of autism are disturbances in afferent modulation. Consequently, children with autism have difficulties in social relating, communication, and language. Because children with autism have these disturbances in rule receptive input appropriately, they suffer from several social and communication problems (Case-Smith & Bryan, 1999). The sensory integration approach attempts to stimulate and challenge the senses of the individual being treated (Cohn, 2001). A common symptom in individuals with autism is being either over steamy under-stimulated by their environment. They often have trouble learning to combine and integrating their different senses.These sensory difficulties may be a cause of communication problems and social interaction problems in children with autism. Because they have such difficulty regulating their sensory systems, they tend to have trouble socializing and interacting with others. Some individuals with autism practice real stereotyped behaviors, such as lining up toys or moving a toy back and forth on a table. This may be an attempt to try and regulate their sensory systems. The sensory integration approach aims to help children with autism improve their sensory processing and modulation. there are three elements typically included in this approach luck parents better understand their childs behavior, support parents/teachers modify the childs environment in order to meet his or hers sensory needs, and helping children organize responses to sensory input. However, each sensory integration therapy session is eccentric to the individual being treated. Occupational therapists must consider different individuals unique needs and goals (Case-Smith & Bryan, 1999).Sensory integration therapy is the most used technique in occupationaltherapy for the treatment of children with autism, with 95% of occup ational therapists using this approach at least some of the time. The reason for its popularity in the treatment of autism is because of its proven efficacy in helping improve social interactions and communications. In a study done by Case-Smith and Bryan (1999) the authors found that sensory integration therapy can significantly increase mastery play, or the childs interactions with the animal(prenominal) environment. They also found that sensory integration therapy significantly decreases non-engaged behaviors, or behaviors where the child is not interacting or minimally interacting with their environment. Examples of these behaviors include unfocused staring or aimless wandering. In a study by Cohn (2001), the author is touch on with parents perspectives of the sensory integration approach used in the treatment of their children. In this study, the author found that sensory integration was successful in helping parents understand their childrens problems. While there is a great overcompensate of research that has been done on the sensory integration approach as a treatment for children with autism and the efficacy of this treatment in improving certain social behaviors, there is not much literature on the make of sensory integration therapy on grades and inculcate performance of children with autism. In circumstance to prior research in relation to autism and the treatment methods, the current study hypothesizes that sensory integration therapy will significantly improves grades and drill performance in children with autism.MethodsParticipantsParticipants of this study will consist of young children with autism or another type of ASD, attending some type of day care or school for children with disabilities. Participants will be in the age group of 3 age old to 7 years old. There will be about 10-15 total participants.MaterialsThis study will be a single-subject design, where each participant serves as his or hers own control group. The study will b e conducted right after a break in school, such as winter break or summer break. When the students return from the break in school, they will attend school for three to four weeks without receiving any therapy or treatment. At the end of this period, grades will be assessed as well as general school performance such hasparticipation and behavior. After the three week period of no therapy, intervention will be initiated and children will all receive sensory integration therapy. Children will receive this therapy deep down the school for six to eight weeks. At the end of this intervention period, grades and school performance will be assessed again.ProcedureThe therapy sessions will take place in the day care or school building. Observations of the participants will be made in the classroom, both before the intervention period and during the intervention period. These observations will assess each childs individual school performance, including things such as participation and class behaviors. Grades will also be assessed both before the intervention and during the intervention period. Students will return to school after their break and will not receive any therapy for three weeks. After the first three weeks, the intervention will be initiated and the children will each participate individually in a form of sensory integration therapy under the supervision of a trained occupational therapist. severally therapy session will be unique to the individual and his or hers unique needs or goals. At the end of the intervention period, grades will be assessed again. The grades and school performance of each child before the therapy was started will be compared with the grades and school performance assessed during and at the end of the therapy, using SPSS or some sort of statistical analysis program, to determine whether or not sensory integration therapy significantly improves grades and school performance in children with autism.ReferencesAgerbo, E., Eaton, W.
