How a simple visual test could detect autism: Brains of children with the condition take 'twice as long to respond to images'

Autism in children could be diagnosed at an earlier age with visual tests, scientists claim.

The US experts say they have made a 'breakthrough' in understanding the disorder which could pave the way for parents and doctors to begin treatment earlier.

For the first time, they have linked a specific chemical messenger called GABA in the brain with autistic behaviour.

People with autism tended to have lower levels of GABA – which calms the brain by resisting chemical messengers which stimulate it.

Low levels of GABA mean the brains of people with autism are too fired up, which also explains why up to a quarter also suffer epileptic seizures.
