A new method of screening autism has been developed by a team of scientists in London.
The researchers, from the Institute of Psychiatry at King's College London, have developed a brain scan that takes just 15 minutes.
Results are 90 per cent accurate at identifying adults on the autistic spectrum.
Dr Jenny Alvarez, head of autism clinical services and consultant clinical psychologist at the Disabilities Trust, commented: "This new research takes us one step further towards an understanding of how the brains of people with autism spectrum conditions may develop differently from others.
"It is an exciting new addition to a growing body of research in this area, showing that subtle differences in the size, shape and structure of the brain may be associated with autism."
The mental disability affects around one in every 100 people in the UK, according to the National Autistic Society.
It can have a "profound and sometimes devastating" effect on individuals and the people around them.
