Autism Vernon - Autism is a neural development disorder which is characterized by impaired communication, social interaction and by restricted and repetitive behavior. These characteristics commonly present before a child is 3 years old.
Autism affects how the nerve cells and their synapses connect and organize and this affects how information is processed in the brain. Why and how this occurs is not greatly understood. There are 3 recognized disorders in the autism spectrum: Pervasive Developmental Disorder-Not Otherwise Specified, which is also referred to as PDD-NOS, and Asperger Syndrome. Asperger Syndrome lacks delays in language and cognitive development. PDD-NOS are diagnosed when the full set of criteria for Asperger Syndrome or autism are not met.
There seems to be a strong genetic basis for autism. The genetics of autism are complicated. It is not clear whether these conditions are explained by rare combinations of common genetic variants or more by rare mutations. In some circumstances, autism is strongly connected with agents that cause birth defects. There have been disagreements surrounding proposed environmental causes like for instance heavy metals and pesticides. At one point there was concern concerning childhood vaccines however this hypotheses is biologically implausible and lacks substantial scientific evidence.
Statistics place the prevalence of autism at about 1 to 2 individuals for every one thousand people throughout the globe. In the USA, the Centers for Disease Control and Prevention reports that approximately 9 out of 1000 children are diagnosed with a kind of autism. Since the 1980s the number of individuals diagnosed has significantly increased. This can be partly due to the changes in diagnostic procedures. It is hard to determine if the actual prevalence has increased.
Normally, parents begin to notice signs of autism within the first 2 years of their kid's life. Usually the symptoms gradually develop, but several children initially develop more normally and afterward they regress. Early behavioural therapy or cognitive intervention can help autistic kids gain communication skills, self-care and social skills.
There have been several instances where children have recovered, though there is no known cure. Various individuals believe that changes to the diet and the avoidances of some environmental chemicals and additives will help to cure this particular condition. nearly all children with autism do not live independently once they become grown-ups, but some have become successful.
Autism has lots of characteristics that are extremely variable. This neuro-developmental disorder initially appears through infancy or childhood and usually follows a steady course without remission. Various indications appear around 6 months of age and then become more established by age 2 or 3, and can continue into adulthood. Autism is characterized by a triad of indications comprising: restricted interests, communication impairments, impairments in social interaction, and repetitive behavior.
