1 Autistic Disorder
Research paper
The word ‘autism’ derives from the Greek word ‘autos’, meaning self. Indeed, the child seems to exist in his or her own world, a place characterized by repetitive routines and profound difficulty in communicating with others.
Autism is a general name for the group of illnesses known as autism spectrum disorders, or ASDs.

That is why autism is called a" behavioural syndrome". The definition and diagnostic criteria depend on the display of patterns of behaviours. According to Happe (1994, pp.7-15).
The Autism Spectrum Disorder it is a condition attributed to abnormal chemistry and biology in the brain. As a matter of fact actual causes of this disorder are unknown, however the abnormalities are under an active research. Probably there are several factors which can cause autism, for example nervous system problems and chromosomal abnormalities are common in families with cases of autism. According to Sanders (2011)
The mechanism of the disability works in the way that it changes the pattern of nerve cells and their synapses’ connection and organization, therefore, affecting a person’s behaviour and communication. The nature of the process is not yet fully understood and for now the condition is considered untreatable.
