Literature Review on Autism Spectrum Disorders

Autism is a complex developmental disability that causes problems with social interaction and communication. Symptoms usually start before age three and can cause delays or problems in many different skills that develop from infancy to adulthood. Disorders included in the Autism Spectrum are Autistic Disorder, Asperger’s Syndrome, and Pervasive Developmental Disorder Not Otherwise Specified. Rett’s syndrome and Childhood Disintegrative Disorder are among the list of related disorders, but are not included in this spectrum. There are no treatments bio-medically,

Autism is the main form of autism spectrum disorders (ASD). Autism is a developmental disorder that is manifested in problems with communication, impairment of social functioning, and repetitive behaviours. According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), ASD diagnoses must meet four different areas of criteria. There are three symptoms of "deficits in social communication and interaction across contexts," four symptoms of "restricted, repetitive patterns of behaviour, interests, or activities," "symptoms must be present in early childhood," and the symptoms must "together limit and impair everyday functioning" (Carpenter, 2013). There are many theoretical positions on the causes of autism spectrum disorders. Some of which have been discounted by empirical studies that have been researched and performed.

Many of us have heard about Autism, also knows as Autism Spectrum Disorder (ASD). Some have a family member, a friend, or know someone who has ASD. Increasingly it is becoming a more common disability. “Autism is one of the fastest-growing developmental disorders in the U.S” (Autism Speaks). Autism has no respect for gender, race, social class and or ethnicity. “Autism is a pervasive developmental disorder that involves abnormal development and function of the brain.” (Autism Center of Excellence) People who have autism have a lot of difficulties with social skills, communication and also will develop behavior issues. These behavior problems of an individual with autism can vary at times and can go from mild to severe. According to the Autism Science Foundation it says,” Many people with the Autism Spectrum Disorder (ASD) also have unusual ways of learning, paying attention, and reacting to different sensations. The thinking and learning abilities of people with ASD can vary—from gifted to severely challenged.” The causes and symptoms, as well as the diagnosis, and the treatments of autism vary.

Autism has become an increasingly important public health concern as the number of yearly diagnoses of the disorder has increased since the late 20th century. The National Institute of Health estimates that 1 in 88 children in the United States are classified as having an Autism Spectrum Disorder (ASD) (NINDS, 2009), a genetic neurodevelopmental disorder that impairs children 's ability to learn and causes issues with social interaction and communication. Symptoms of ASD include delays in speech and language, issues with social interaction, and unusual behaviors/routines.

Over the years, more people are becoming aware of Autism Spectrum Disorder, ASD. The growing number of individuals who are affected by ASD have been increasing over the years. This could be do to the new DSM development of what is considered ASD or simply more children are being born with ASD. Either way, ASD is more predominate in our society today. ASD is defined in the DSM 5 as having abnormal social aspects, lack of social skills, non-verbal communications skills, deficits in development, lack of understanding of relationships, and self-stimulation through repetitive behaviors (American Psychiatric Association, 2013). Although these are not all of the symptoms caused by ASD

Autism disorder is an issue facing many people today. It’s an issue widely discussed in the news and social media. In Gale’s data from 2015 defines autism as a general term for a group of complex disorders of the brain development that are grouped together under the broader term of autism spectrum disorder also known as ASD. According to the Centers for Disease Control and Prevention (CDC), as of 2014, about 1 in 68 out of 1,000 children were diagnosed with ASD. This was a dramatic increase from 1 in 150 children in 1992. The CDC also

To understand the etiology of Autism one must understand that Autism belongs to a group of developmental disabilities that have been identified as Autism Spectrum Disorders. The name "spectrum” indicates that the disorder is broad and it affects each individual differently. Autism Spectrum Disorder commonly referred to as (ASD) encompass delays in the development of many basic skills. These delays in development include but are not limited to: limited or inability to properly socialize or establish relationships with others, effective communication skills, restricted interests and repetitive behaviors. Individuals with Autism may also have (ID) intellectual disabilities,

Chapter 1 focuses on autism, Pervasive Developmental Disorders (PDDs) and other Autistic Spectrum Disorders (ASDs). Described in 1943 by Dr. Leo Kanner, autism (also known as autistic disorder, childhood autism, or infantile disorder) is one of the PDDs along with Rett's disorder, Childhood Disintegrative Disorder (CDD) referred to as Heller's syndrome, Asperger disorder, and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). Rett's is a rare genetic abnormality affecting brain development in girls. There are treatments available, but there is no known cure. Asperger disorder affects an individual's ability to socialize and communicate effectively. Individuals with Asperger disorder may be socially awkward and have a compulsive

Every year one in 68 Americans is diagnosed with autism. There are more than 3.5 million Americans living with an autism spectrum disorder (Autism Society), which makes it the fastest growing developmental disorder in the United States, hence the significant amount of studies being done to explore its characteristics and find solutions. Autism, also known as ASD, is a complex neurodevelopmental disorder that is categorized by dysfunctions in social situations, communications, constrained interests, and repetitive stereotypic behaviors (Siniscalco et al). These behaviors can range from mild to very severe, and may be accompanied with other disorders. Autism can be diagnosed during early childhood, while symptoms begin to show during the first

Each year, more than 200,000 people are diagnosed with the Autism Spectrum Disorder (ASD) in the U.S. ASD or Autism can be characterized as a brain development disorder that directly affects the nervous system. As noted on AutismSpeaks.org, ASD can be deemed as an intellectual disability. Symptoms of Autism can include difficulty with communication, difficulty in social interactions, obsessive interests, and repetitive behaviors. The severity of these symptoms vary with all ASD patients. Some patients with ASD thrive in non-interactive subjects such as math, art, and music.

Autism continues to spark countless discussions and debates throughout the medical field. Some doctors believe that autism is a neurological disorder that can and should be treated, as others continue to think it is simply a difference in human adaption that needs to be nurtured and acknowledged. Regardless of what autism may be, it continues to dramatically rise in the number of children and families affected. With autism being based on such a broad spectrum, the affects and causes leaves the medical world searching for answers in unending stacks of research.

Autism is a mental condition that can occur in children from birth but is diagnosed in early infancy or early childhood. It is a complex neurobiological disorder that typically lasts throughout the lifetime of a person. It can be considered as a spectrum of disorders characterized by severe developmental deficiencies that can affect socialization, communication, emotional development and can cause repetitive or unusual behaviors. The ranges of the symptoms are mild to severe. There is a milder form of the disorder known as Asperger syndrome. Other developmental disorders that fall under the category of autism spectrum disorders are Rett Syndrome, PDD (Pervasive Developmental Disorders) and childhood disintegrative disorder.

Autism is known as Autism Spectrum Disorder (ASD) this is a neurodevelopmental disorder, characterized by reduced social interaction, verbal, and non-verbal communication and restricted and repetitive behavior. (Langone, 2002, p. 3). ASD can also be linked with many other symptoms such as intellectual disability, difficulties in motor coordination, attention, and physical health issues. Sleep and gastrointestinal disturbances, are known as the physical health issues (Langone, 2002, p. 4). Autism appears to develop and show signs in the early stages of the brain development, specifically between the ages of 2 and 3 years old.

Autism is an exceptionally that effects many people. In order to truly understand autism one must research certain information that helps unpack what autism is and how to help these induvial with any form of an autism spectrum disorder (ASD). This study will include the definition, statistics, characteristics, behaviors, challenges, accommodations, diagnostic tactics, and strategies in order to gain a full perspective of ASD.

Autism is a mental condition, present from early childhood, characterized by difficulty in communicating and forming relationships with other people and in using language and abstract concepts (“Autism” Def). It’s a disability that affects a person’s communication skills and/or changes in behavior. Autism is usually diagnosed before three years of age and has a lifelong persistence. The causes of this disorder is unclear and there is currently no cure for it. There are two core characteristics of autism. The first being a deficiency in social communication and social interaction. The second is a restricted, repetitive patterns of behaviors, interests, and activities. Clinical features of autism include walking on tiptoes, lack of eye contact, extreme dislike of certain foods or sounds, poor communication skills, repetitive behaviors, and
