Brain scans may reveal signs of autism, which could eventually aid in early intervention therapies, according to new research.
Researchers using a functional magnetic resonance imaging (fMRI) scanner measured the brain activity of volunteers with autism spectrum disorders against controls and say the comparisons reveal disrupted brain connectivity that could serve as a neural signature of autism.
While the study is both preliminary and small — including only 30 volunteers — the findings, which appear online Friday in the journal Frontiers in Human Neuroscience, joins a wider range of autism research that could ultimately help supplement current behavior-based diagnoses and possibly help in deciding early intervention therapies.
“This research suggests brain connectivity as a neural signature of autism and may eventually support clinical testing for autism,” said Rajesh Kana, an associate professor of psycholog… [Read more]
