Autism diagnosis by brain scan

August 11, 2010

Scientists from the Institute of Psychiatry (IoP) at King’s College London have developed a 15-minute MRI brain scan that can identify adults with autism with over 90 per cent accuracy. The method could lead to the screening for autism spectrum disorders in children in the future.

An imaging technique was used to reconstruct the scans into 3D images that could be assessed for structure, shape and thickness – all intricate measurements that reveal Autism Spectrum Disorder (ASD) at its root. By studying the complex and subtle make-up of grey matter in the brain, the scientists can use biological markers, rather than personality traits, to assess whether or not a person has ASD.

Until now, diagnosis has mainly relied on personal accounts from friends or relatives close to the patient – a long and drawn-out process hinged on the reliability of this account and requiring a team of experts to interpret the information.

The paper, “Describing the brain in autism in five dimensions – MRI-assisted diagnosis using a multi-parameter classification approach,” was published in the Journal of Neuroscience on Aug. 10.
