Autism Bathhurst - Autism is a neural development disorder which is characterized by social interaction, impaired communications and by restricted and repetitive behavior. These characteristics commonly present before a child is 3 years old.
Autism affects the way the nerve cells and their synapses organize and connect and this affects how information is processed in the brain. Why and how this occurs is not really understood. There are 3 known disorders in the autism spectrum: Pervasive Developmental Disorder-Not Otherwise Specified, that is often abbreviated 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 autism or Asperger Syndrome are not met.
Genetics seem to be strongly connected with autism. The genetics of autism have proven to be rather complicated and it is unclear whether some cases of autism are explained by rare mutations in the genes or by rare combinations of common genetic variants. In various circumstances, autism is strongly linked with agents that lead to birth defects. There have been debates surrounding proposed environmental causes like heavy metals and pesticides. At one point there was concern regarding childhood vaccines although this hypotheses is biologically implausible and lacks strong scientific proof.
Statistics place the prevalence of autism at about 1 to 2 people for every 1000 people throughout the world. Within the USA, the Centers for Disease Control and Prevention reports that about 9 out of 1000 kids are diagnosed with a kind of autism. Ever since the 1980s the number of individuals diagnosed has dramatically increased. This could be partially because of the changes in diagnostic procedures. It is hard to determine if the actual prevalence has increased.
Usually, parents begin to notice signs of autism in the initial 2 years of their child`s life. Usually the symptoms progressively develop, but some children initially develop more normally and afterward they regress. Early cognitive intervention or behavioural therapy can help autistic children gain self-care, social skills and communication skills.
There have been some instances where kids have recovered, though there is no known treatment. Various individuals believe that changes to the food intake and the avoidances of some environmental additives and chemicals will help to cure this particular condition. The majority of children with autism do not live independently once they become adults, but some have become successful.
The characteristics of autism are often very variable. Initially, this neuro-developmental disorder appears in early childhood and normally follows a steady course without remission. Some signs appear about 6 months of age and after that 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, repetitive behavior and impairment in social interaction.
