11 Most Threatening Disorders That Attack Children
Autism spectrum disorder and autism are both general terms for a group of complex developmental disorders that are characterized by difficulty in relating to others, verbal and non-verbal communication problems, and repetitive behaviors.
These conditions, which differ from each other in varying degrees in which the symptoms manifest, used to be distinct from each other. In May 2013, in the publication of the DSM-5 Diagnostic Statistical Manual autism, Asperger syndrome and pervasive developmental disorder (PDD), which were at first thought to be distinct, were placed under the umbrella term – autism spectrum disorder (ASD).
Common symptoms of the disorder are difficulty in communication and motor coordination, intellectual disability as well as physical health issues.
Repetitive behavior is often observed in children with autism. They also tend to get quite upset with a change in routine. They may appear “deaf” because they may have trouble speaking or do not respond when called, despite hearing tests testing against deafness. Although having some intellectual disability a number of people who are diagnosed with ASD can be quite brilliant in music, math and art. Signs and symptoms become apparent at around 2 to 3 years of age. There is very limited insight as to what causes autism but it seems to be genetic.
According to the CDC (Centers for Disease Control and Prevention) as of 2010, 1 in 68 children in the U.S. is diagnosed with ASD. The report occurs across all ethnicities but is 5 times more common in boys than it is in girls.
ASD tends to occur along with other genetic and chromosomal conditions. In fact, 10% of all cases diagnosed with ASD may have tuberous sclerosis, fragile X chromosome and Down syndrome.
