Autism: Characteristics, Causes, And Treatments
Autism is a complex developmental disorder that generally emerges before the age of three. Individuals with autism demonstrate difficulties in communication, both verbal and non-verbal, as well as difficulties in socially interacting with others, as well as leisure and play activities (Autism Society of America, 2003). Autism is one five disorders that are classified as Pervasive Developmental Disorders in the DSM-IV, which are all neurological disorders that are characterized by severe and ubiquitous impairments in many areas of development.
As the most common Pervasive Developmental Disorder, Autism affects approximately 2 to 6 out of every 1,000 individuals, which translates into as many as 1.5 million Americans (Autism Society of America, 2003). The number of cases of autism appear to be increasing at a rate of about 10 to 17% per year, which means that the number of cases of autism could reach 4 million in the United States within the next ten years (Autism Society of America, 2003). However, these increased rates may be due to a greater awareness and recognition among parents and healthcare professionals, with regards to autism (Harvard Mental Health Letter, 2003). An in-depth understanding of Autism requires exploration of the characteristic, causes and treatments available in relation to this disorder.
Characteristics of autism
The Autism Society of America (2003) explains how autism is known as a spectrum disorder, which means that the symptoms of the disorder can appear in various combinations and to various degrees, from mild to severe. Generally, individuals with autism process and respond to information differently than individuals without the disorder, which sometimes includes the presence of aggressive or self-destructive behavior, as well as language difficulties. However, the assumption that autistic children lack language ability completely is oversimplified, as autistic children tend to comprehend and use language differently than other children, and to various degrees (Carson et al., 1998). Many children...
These traits include: resistance to change; difficulty expressing needs; echolalia (word repetitiveness); unpredictable or inappropriate emotional reactions; aloofness; tantrums; difficulties in everyday social interactions; resistant to physical affection; little or no eye contact; does not respond to conventional teaching approaches; odd play; spins object; inappropriate attachments to objects; differing sensitivities to pain; no concept of fear or danger; differing levels of physical activity; difficulties with motor skills; unresponsive to verbal cues, although hearing tests produce normal results (Autism Society of America, 2003). Individuals with autism may present with some or all of these traits, with a variety of combinations and degrees of severity.
In regards to the diagnosis of autism, there are no definitive medical tests that determine the presence or absence of autism. An accurate diagnosis of the disorder relies on various observations of the communication, behavior, and developmental levels of the individual (Autism Society of America, 2003). Input from parents and caregivers, regarding developmental history, is crucial for an accurate diagnosis. An early diagnosis of autism has been related to markedly more successful outcomes for individuals with autism (Autism Society of America, 2003). Early diagnosis sets the stage for the development of an effective and appropriate program to suit the individual's treatment and educational needs.
The characteristic behaviors of autism that are watched for in diagnosis of the disorder usually become apparent by the age of 6 years at the very latest. According to the Autism Society of America (2003), there are five behaviors that indicate the need for further evaluation for the diagnosis of autism. These include: 1) child does not babble or coo by the age of 12 months, 2)…
