Autism is a spectrum disorder that affects an individual’s ability to communicate and relate to others. It is a type of pervasive developmental disorder (PDD) that is lifelong and can result in some social isolation.

The cause of Autism is not known, although research has shown differences in brain structure between children with autism and non-autistic children. Some early research has also indicated that Autism could be genetic, with parents who have an autistic child more likely to have another child with autism.

It has also being shown that autism is more prevalent in those who have certain conditions including untreated Phenylketonuria (PKU), Fragile X Syndrome, Tuberous Sclerosis and Congenital Rubella Syndrome.

The symptoms of autism typically develop within the first three years of life. All people with Autism experience difficulty with social interaction, and children might prefer to play alone and make little eye contact with other people. Babies with autism may not babble talk and may also seem to have hearing difficulties. Language development is almost always delayed in children with autism.

Sufferers may have difficulties in both verbal and non-verbal communication, have limited, patterned or over-used behaviour patterns, play and interests. These include repetitive body rocking, forming unusual attachments to objects and resisting change (holding to routines and rituals, for example).

The world-wide incidence of autism is consistent around the globe, but it has been shown that it is four times more prevalent in boys than girls. The development of autism is not affected in any way by race, ethnicity, social boundaries, family income, lifestyle or educational levels.
