Autism is a complex developmental disability that typically appears during the first three years of life. This is the result of a neurological disorder that affects the functioning of the brain.

Autism is four more times prevalent in boys than girls. Autism shows no racial, ethnic or social boundaries. Family income, lifestyle and educational levels do not affect the chance of autisms occurrence. Autism and its associated behaviors have been estimated to occur in as many and one in 500 individuals. In this essay, I will discuss the signs and symptoms of autism, types of autism, the diagnosis of autism and studies done on autism.

Autism affects the normal development of the brain in the areas of social interaction and communication skills. Children and adults with autism have difficulties in verbal and non-verbal communication, social interactions and leisure or play activities. This disorder makes it hard for them to relate to the outside world. It is hard for them to communicate with others. Aggressive and/or self-injurious behavior may be present in some cases. They may exhibit repeated body movement, such as hand flapping or rocking, unusual responses to people or attachments to objects and resistance to changes in routines. They possibly will experience sensitivities in the five senses of sight, hearing, touch, taste and smell.

Children will be within the pervasive development until the ages of 24-30 months, when parents may notice delays in language, play or social interaction. If any of these symptoms occur by themselves, that would not result in a diagnosis of autism. Autism is a combination of several developmental challenges.

There are many symptoms of autism. They include: extreme difficulty in learning language, inappropriate response to people, avoiding eye contact, resisting being picked up or cuddled, uncooperative play with other children, extreme hyperactivity and many others. There are five major areas in children highly affected by autism. They are communication, social interaction, sensory impairment, play and behavior.

Every person with autism has a unique personality and combination of characteristics. Some autistic people mildly affected may exhibit only slight delays in language and communication and greater challenges with social interactions. The abilities of an autistic child may fluctuate from day to day due to difficulties in processing, concentration or anxiety. They may show evidence of learning one day, but not the next. Learning can be affected by external stimuli and anxiety. They may have average or above average verbal, memory or spatial skills but find it difficult to be imaginative or join in activities with others. Individuals with more severe challenges may require intensive support to manage basic tasks and needs of day to day living.

Contrary to popular belief, many individuals with autism make eye contact, show affection, smile, laugh and demonstrate a variety of other emotions, although in varying degrees. Like others, they respond to environment with both negative and positive ways. Autism may affect their range of responses and make it more difficult to control how their bodies and minds react. Sometimes motor, visual, and/or processing problems make it difficult to maintain eye contact with others. Some autistic people use peripheral vision rather than looking directly at others. Sometimes the closeness or touch of others may be painful, resulting in withdrawal.

Several related disorders are grouped under “Persuasive Developmental Disorder” or PDD- a general category of disorders, which are characterized by severe and persuasive impairment in several areas of development. A PDD is diagnosed when a specified number of characteristics are present. Diagnostic evaluations are based on the presence of specified behaviors indicated by observation and through parent consultation, and should be made by a highly trained team. Thus, when professionals or parents are referring to different types of autism, often they are distinguishing autism from one of the other persuasive developmental disorders.

Individuals who fall under the PDD category exhibit commonalities in communication and social deficits, but differ in severity. The five different diagnoses are: Autistic Disorder, Aspergers Disorder, Persuasive Developmental Disorder, Retts Disorder and Childhood Disintegrative Disorder.

Autistic Disorder includes impairments in social interaction, communication and imaginative play prior to age three. An autistic child will also have stereotyped behaviors, interests and activities.

Aspergers Disorder is characterized by social impairments in social interactions and the presence of restricted interests and activities with no clinically significant general delay in language, and testing in a range of average intelligence.

A Persuasive Developmental Disorder-Not otherwise specified (commonly referred to as atypical autism) a diagnosis may be made when a child does not meet the criteria for a specific diagnosis, but there is a severe and persuasive impairment in specified behaviors.

Retts Disorder is a progressive disorder, which has occurred only in girls. It includes a period of normal development and then a loss of previously acquired skills, loss of purposeful use of the hands replaced with repetitive hand movements beginning at the ages of one to four years.

Childhood Disintegrative Disorder is characterized by normal development for at least the first two years, showing significant loss of previously acquired skills.

Researchers have devoted a considerable time and energy into finding the answer to what causes autism. Medical researchers have explored numerous explanations for the various forms of autism. Although a specific cause is not known, current research links autism to biological or neurological differences in the brain. In many families, there appears to be a pattern of autism or related disabilities. This suggests that there is a genetic basis to the disorder. Buty there has been no gene linked directly to autism. The genetic basis is believed by researchers to be highly complex, probably involving several genes in combination.

Autism is not a mental illness. Children with autism are not unruly kids who choose not to behave. Autism is not cause by bad parenting. These are just some of the several theories that are false about the cause of autism. They have been proven false. Furthermore, no known psychological factors in the development of the child have been shown to cause autism.

An accurate diagnosis must be based on observation of the individuals communication, developmental levels and behavior. Because many of the behaviors associated with autism are shared by other disorders, various medical tests may be ordered to rule out or identify
