Autism While autism is highly heritable, researchers suspect both environmental and genetic factors as causes. In rare cases, autism is strongly associated with agents that cause birth defects. Controversies surround other proposed environmental causes; for example, the vaccine hypotheses have been disproven.iagnosis is based on behavior, not cause or mechanism. Under the DSM-5, autism is characterized by persistent deficits in social communication and interaction across multiple contexts, as well as restricted, repetitive patterns of behavior, interests, or activities.

- Autism spectrum disorder is a serious neurodevelopmental disorder that impairs a child's ability to communicate and interact with others.It also includes restricted repetitive behaviors, interests and activities. These issues cause significant impairment in social, occupational and other areas of functioning.t's not clear whether this is due to better detection and reporting or a real increase in the number of cases, or both. While there is no cure for autism spectrum disorder, intensive, early treatment can make a big difference in the lives of many children.

Autism spectrum A revision to autism spectrum disorder (ASD) was proposed in the Diagnostic and Statistical Manual of Mental Disorders version 5 (DSM-5), released May 2013. The new diagnosis encompasses previous diagnoses of autistic disorder, Asperger's disorder, childhood disintegrative disorder, and PDD-NOS.hile a specific cause or specific causes of autism spectrum disorders has yet to be found, many risk factors have been identified in the research literature that may contribute to the development of an ASD.

Autism Autism: Causes, Risks and Treatment. Autism is a developmental disability that usually appears during the first three years of life. It is a neurological disorder that impacts the normal development of the brain in the areas of social interaction and communication skills. According to the Centers for Disease Control and Prevention, 2010, autism is the most common of the Pervasive Developmental Disorders, affecting an estimated 1 in 68 births.

- Occasionally, a child with autism may display an extraordinary talent in art, music, or another specific area. The cause of autism remains unknown, although current theories indicate a problem with the function or structure of the central nervous system. What we do know, however, is that parents do not cause autism. Children with autism need a comprehensive evaluation and specialized behavioral and educational programs.

- The true cause of autism is being covered-up. Essentially, autism is an extreme, selfish reaction. As with every other mental illness or behavior disorder, the causes of autism are psychological, not biological. Every autistic child is in an extreme state of selfish reaction.

Autism spectrum disorders (ASD), including Asperger syndrome, are developmental disorders that begin in early childhood, persist throughout adulthood, and affect three crucial areas of development: communication, social interaction and restricted patterns of behavior.

Causes of autism Many causes of autism have been proposed, but understanding of the theory of causation of autism and the other autism spectrum disorders (ASD) is incomplete.Research indicates that genetic factors predominate. The heritability of autism, however, is complex, and it is typically unclear which genes are responsible.In rare cases, autism is strongly associated with agents that cause birth defects.he risk of autism is associated with several prenatal risk factors, including advanced age in either parent, diabetes, bleeding, and use of psychiatric drugs in the mother during pregnancy.

Autism Autism Causes. Although autism is the result of a neurologic abnormality, the cause of these problems with the nervous system is unknown in most cases. Research findings indicate a strong genetic component. Most likely, environmental, immunologic, and metabolic factors also influence the development of the disorder.lthough autism is the result of a neurologic abnormality, the cause of these problems with the nervous system is unknown in most cases.

- Autistic disorder, sometimes called autism or classical ASD, is the most severe form of ASD, while other conditions along the spectrum include a milder form known as Asperger syndrome, and childhood disintegrative disorder and pervasive developmental disorder not otherwise specified (usually referred to as PDD-NOS).n some cases, parents and other relatives of a child with ASD show mild impairments in social and communicative skills or engage in repetitive behaviors. Evidence also suggests that some emotional disorders, such as bipolar disorder, occur more frequently than average in the families of people with ASD.

Autism Autism is a developmental disorder characterized by troubles with social interaction and communication. Often there is also restricted and repetitive behavior. Parents usually notice signs in the first two or three years of their child's life. These signs often develop gradually, though some children with autism reach their developmental milestones at a normal pace and then worsen. Autism is caused by a combination of genetic and environmental factors. Risk factors include certain infections dur
