Brain scans reveal differences in people with genetic autism
Children with autism spectrum disorder (ASD) all have problems socialising, but beyond that their disorders can be vastly different. That makes it hard for doctors to diagnose what their degree of impairment is likely to be, and how best to optimise interventions.
So far brain scans have not been all that helpful. Largely because ASD is so diverse; affected children may have larger, smaller or normal sized brains.
Now a new study that focused on one genetic subtype of ASD, reports finding a link between brain changes on a scan and behavioural and cognitive impairments. Though it is still too early for clinical use, the finding “will help us understand the range of outcomes”, says study senior author Elliot Scherr, a neurologist at the University of California, San Francisco. The study, published in the journal Radiology, also involved collaborators at Baylor College of Medicine in Houston, Massachusetts General Hospital and the Hospital of Philadelphia.
