RESEARCHBiomarker for Autism Discovered

Researchers have identified the reduced activity in a part of the brain associated with empathy and argue it may be a 'biomarker' for a familial risk of autism. (Credit: Spencer) ScienceDaily — Siblings of people with autism show

a similar pattern of brain activity to that seen in people with autism when looking at emotional facial expressions. Researchers at the University of Cambridge identified the reduced activity in a part of the brain associated with empathy and argue it may be a 'biomarker' for a familial risk of autism. Dr Spencer, who led the study from the University's Autism Research Centre, said: "The findings provide a springboard to investigate what specific genes are associated with this biomarker. The brain's response to facial emotion could be a fundamental building block in causing autism and its associated difficulties." The Medical Research Council funded study is published on the 12th of July, in the journal Translational Psychiatry. Previous research has found that people with autism often struggle to read people's emotions and that their brains

process emotional facial expressions differently to people without autism. However, this is the first time scientists have found siblings of individuals with autism have a similar reduction in brain activity when viewing others' emotions. In one of the largest functional MRI (fMRI) studies of autism ever conducted, the researchers studied 40 families who had both a teenager with autism and a sibling without autism. Additionally, they recruited 40 teenagers with no family history of autism. The 120 participants were given fMRI scans while viewing a series of photographs of faces which were either neutral or expressing an emotion such as happiness.
