Autism is defined as neuro-developmental disorder that is characterized by repetitive and restricted behavior, verbal and non-verbal communication and impaired social interaction. Signs are normally noted during the first two years of their children being born. Signs normally develop gradually over time, though certain children with autism may reach their developmental achievements at normal pace and regress. The entire diagnostic criteria require that symptoms become evident during early childhood, normally within the first three years of birth.
Although autism is a highly heritable condition, research studies indicate genetic and environmental factors to be the main causes. In certain cases, although rare, autism is largely associated with elements that cause birth defects. There is a lot of controversy that surrounds different other suggested environmental causes, for instance, the hypotheses on vaccine have been unproven. Autism has an effect on the way in which the brain processes information by changing the manner nerve cells and synapses organize and connect; how this happens is not really understood. It's among the three disorders of the autism spectrum, with the other two being Asperger syndrome and pervasive developmental disorder (PDD). Asperger syndrome defines a delay in language and cognitive development and PDD is not really specified but diagnosed when a complete set of criteria for Asperger syndrome or autism are not met.
Behavioral interventions or early speech can enable children with autism to gain self-care, communication, and social skills. While there isn’t a known cure for the condition, there have been some reported cases about children who’ve recovered. A few children with autism get to live independently after they reach adulthood, although some go on to become successful. In recent times, a new autistic culture has become advent, with some people searching for a cure and some believing that the condition should be accepted and not treated like a disorder.
Based on data from 2010, the number of people with autism was estimated to be about 1-2 for every 1,000 people globally. The condition is also 4-5 times more likely to develop among boys than girls. An estimated 1.7 percent of children in the U.S. are diagnosed with the condition, and as of 2014 there had been a 30 percent increase from 1 in 88 in 2012. Autism among adults in the United Kingdom is 1.1 percent. The number of new cases has increased dramatically from the 1980s, largely because of changes in government-subsidized financial incentives and diagnostic practice for named diagnoses, but the question of whether the actual rates have risen remains unresolved.
