The effect of this disorder is in the brain where there is an alteration of the way that synapses and their respective nerve cells connect and organize.
However, there has been an increased number in the reported cases of autism since the 80’s.
This fact does not necessarily point to an increased number in the people affected but rather an improvement in the manner of detection of the disorder.
Autism is a disorder that is characterized by repetitive behavior that is restricted.
Its manifestation is in impaired social interactions of affected children and also impaired communication.
This is in sharp contrast to the prevalence rate in the US where 9 in every 1,000 children are diagnosed with the disorder.
Additionally, autism is common 3-4 times more in boys than in girls.Parents whose children have the disorder usually start noticing the symptoms when the child is about 2 years old (Arndt, Stodgell and Rodier, 2005).From then, depending on the child, the symptoms may develop slowly or may become severe at that stage in development.Although these symptoms are common in all the disorders, their severity and variability differ from individual to individual.There are a variety of remedies that can be administered in order to reduce the symptoms and attempt to manage the disorders.There are many children in the world who seem to have a problem with learning, communicating with others and other peculiarities that make them seem “abnormal”.A wide range of disorders can be the cause of this behavior in many children and are classified under Pervasive developmental disorders (PDD) (Caronna, Milunsky, & Tager-Flusberg, 2008).The disorders include Asperger’s syndrome, childhood disintegrative disorder (CDD), pervasive developmental disorder not otherwise specified (PDDNOS), Rett’s syndrome and Autism.These disorders can be recognized during infancy and any time before the child reaches 3 years of age.There is a vaccine that has been developed aiming at reducing the prevalence of autism in children under the age of 3.Worldwide, surveys have shown that 1 to 2 children per every 1,000 are affected by the disorder.
