Autism Hamilton - The neural development disorder labeled autism is often characterized by impaired communication, social interaction and by restricted and repetitive behavior. These characteristics would normally become present prior to the child reaching the age of three.
The affects of autism will impact the way nerve cells and their synapses communicate, connect and organize their information in the brain. In is not fully understood how and why this happens. There are 3 known disorders in the autism spectrum: Pervasive Developmental Disorder-Not Otherwise Specified, that is likewise 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 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 not clear whether some conditions of autism are explained by rare combinations of common genetic variants or by rare mutations in the genes. In various conditions, autism is strongly associated with agents that lead to birth defects. There have been debates surrounding proposed environmental causes like for instance heavy metals and pesticides. At one point there was concern about childhood vaccines although this hypotheses is biologically implausible and lacks strong scientific proof.
The prevalence of autism all-around the world presently affects 1 to 2 individuals for each one thousand. The CDC or Centers for Disease Control and Prevention within the United States, reports that about 9 out of 1000 kids are diagnosed with a form of autism. 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.
Normally, parents start to notice indications of autism within the initial 2 years of their kid's life. Often the signs progressively develop, but various children initially develop more normally and next they regress. Early cognitive intervention or behavioural therapy can help autistic kids gain communication skills, self-care and social skills.
However, there is no actual treatment known, there have been many instances of children who have recovered. Many individuals believe that dietary changes and prevention of certain additives and chemicals within particular foods have the ability to cure this condition. The majority of children with autism do not live separately once they reach adulthood, 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. Various signs appear about 6 months of age and after that become more established by age 2 or 3, and could continue into adulthood. Autism is characterized by a triad of symptoms consisting of: communication impairments, restricted interests, repetitive behavior and impairment in social interaction.
