Autistic disorder, sometimes called autism or classical ASD, is the most severe form of ASD, while other conditions along the spectrum include a milder form known as Asperger syndrome, the rare condition called Rett syndrome, and childhood disintegrative disorder and pervasive developmental disorder not otherwise specified . Although ASD varies significantly in character and severity, it occurs in all ethnic and socioeconomic groups and affects every age group. Experts estimate that two to six children out of every 1,000 will have ASD. Males are four times more likely to have ASD than females. What are some of the signs? Many children with ASD engage in repetitive movements such as rocking and twirling, or in self-abusive behavior such as biting or head-banging. They also tend to start speaking later than other children and may refer to themselves by name instead of “I” or “me.” Children with ASD don’t know how to play interactively with other children.
Some speak in a sing-song voice about a narrow range of favorite topics, with little regard for the interests of the person to whom they are speaking. Children with ASD appear to have a higher than normal risk for certain co-occurring conditions, including Fragile X syndrome (which causes mental retardation), tuberous sclerosis (in which tumors grow on the brain), epileptic seizures, Tourette syndrome, learning disabilities, and attention deficit disorder. About 20 to 30 percent of children with ASD develop epilepsy by the time they reach adulthood. While people with schizophrenia may show some autistic-like behavior, their symptoms usually do not appear until the late teens or early adulthood.
Most people with schizophrenia also have hallucinations and delusions, which are not found in autism. There are cases in which is called mild autism. High functioning autism is considered mild autism. A child with mild autism communicates and develops social skills better than a child with a more severe case of autism. In fact, sometimes parents do not recognize the autism symptoms in an infant and toddler. Since early diagnosis and treatment provide the best chance for a healthy life, parents should learn the signs of mild autism. Here are some of the signs of mild autism. Developmental delays- The child experiences delays in some or all of the developmental milestones such as cognitive, language, social, gross motor and fine motor skills. Speech and Language Problems- The child takes longer to learn to talk. Once he talks, he struggles with expanding his vocabulary.
