au•tismˈɔ tɪz əm(n.)
a pervasive developmental disorder characterized by impaired communication, extreme self-absorption, and detachment from reality.
Origin of autism:
1910–15; < Gk aut(ós) self + -ism
(psychiatry) an abnormal absorption with the self; marked by communication disorders and short attention span and inability to treat others as people
Bio-neurological disorder that is observable in early childhood with symptoms of abnormal self-absorption, characterised by lack of response to other humans and by limited ability or disinclination to communicate and socialize.
Origin: Coined in 1912 by Swiss psychiatrist Paul Bleuler (1857-1939) from autismus, from αὐτός.
Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior. The diagnostic criteria require that symptoms become apparent before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood. It is one of three recognized disorders in the autism spectrum, the other two being Asperger syndrome, which lacks delays in cognitive development and language, and pervasive developmental disorder, not otherwise specified, which is diagnosed when the full set of criteria for autism or Asperger syndrome are not met. Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether ASD is explained more by rare mutations, or by rare combinations of common genetic variants. In rare cases, autism is strongly associated with agents that cause birth defects. Controversies surround other proposed environmental causes, such as heavy metals, pesticides or childhood vaccines; the vaccine hypotheses are biologically implausible and lack convincing scientific evidence. The prevalence of autism is about 1–2 per 1,000 people worldwide, and the Centers for Disease Control and Prevention report 20 per 1,000 children in the United States are diagnosed with ASD as of 2012. The number of people diagnosed with autism has been increasing dramatically since the 1980s, partly due to changes in diagnostic practice and government-subsidized financial incentives for named diagnoses; the question of whether actual prevalence has increased is unresolved.
