Autism Guelph - Autism is a neural development disorder that is characterized by impaired communication, social interaction and by repetitive and restricted behavior. These characteristics commonly present before a child is 3 years old.
Autism affects the way the nerve cells and their synapses connect and organize and this affects the way information is processed in the brain. Why and how this occurs is not really understood. There are 3 recognized disorders within the autism spectrum: Pervasive Developmental Disorder-Not Otherwise Specified, that is likewise known as PDD-NOS, and Asperger Syndrome. Asperger Syndrome lacks delays within 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 somewhat complex and it is not clear whether certain cases of autism are explained by rare combinations of common genetic variants or by rare mutations in the genes. In several circumstances, autism is strongly linked with agents which cause birth defects. There have been debates surrounding proposed environmental reasons including pesticides and heavy metals. At one point there was concern concerning childhood vaccines although this hypotheses is biologically implausible and lacks substantial scientific proof.
The prevalence of autism throughout the world presently affects 1 to 2 individuals for every one thousand. The CDC or Centers for Disease Control and Prevention within the United States, reports that around 9 out of one thousand children are diagnosed with a type of autism. Ever since the 1980s the number of individuals diagnosed has dramatically increased. This could be partially due to the changes in diagnostic procedures. It is hard to determine if the actual prevalence has increased.
Parents will often start to notice signs of autism within the first 2 years of their kid's life. The indications will gradually develop, while several children would initially develop more normally and then they regress. Early cognitive intervention or behavioural therapy can help autistic kids gain social skills, communication skills and self-care.
There have been several instances where children have recovered, though there is no known cure. Various individuals believe that changes to the food intake and the prevention of particular environmental additives and chemicals would help to treat this condition. Most kids with autism do not live alone once they reach adulthood, but some have become successful.
The characteristics of autism are normally extremely variable. At first, this neuro-developmental disorder appears in early childhood and typically follows a steady course without remission. Some signs appear about 6 months of age and next become more established by age 2 or 3, and could continue into adulthood. Autism is characterized by a triad of signs consisting of: restricted interests, communication impairments, impairments in social interaction, and repetitive behavior.
