How common is autism?

There are over half a million people living with autism in the UK. This figure includes all conditions on the autistic spectrum, including classic autism, Asperger syndrome and high-functioning autism.
Autistic spectrum disorders are more common in boys than girls and affect around 1 in 100 children in the UK.
There are three major forms of autistic spectrum disorders; these are:
• Classic autism (also known as autistic disorder)
• Asperger syndrome
• Pervasive Developmental Disorder-Not Otherwise Specified (PDDNOS) (also known as atypical autism)
The autistic spectrum

Autism affects people to different degrees and in different ways, which is why an autistic person’s condition is often referred to based on an autistic spectrum.
Some types of autistic disorder affect people differently to other types. Some are only mildly affected by their condition, while others find it very difficult to live a normal life and may struggle throughout their childhood and adult lives.
Some people with severe conditions require round the clock care and attention.
The effects of autism
Autistic people see the world in a different way to other people. They are often rigid and reserved and have difficulties building friendships and loving relationships because they find it difficult to understand other people’s feelings and emotions.
Many people with autism also have difficulties expressing how they feel and lack communication and social skills. Some autistic people have said that they find the world a very confusing and frightening place because they struggle to make sense of everything that goes on.
Autism affects different people in different ways. Some people have incredible concentration skills but struggle to be around other people or communicate how they are feeling, others are gifted when it comes to problem solving or learning dates or facts and some people never learn to speak and require 24 hour care.
