摘要

A study published recently in the widely read clinical journal Radiology correctly identified 36 out of 39 children and adolescents with autism solely by the use of functional magnetic resonance imaging (fMRI)1. The researchers reported that as the subjects listened to their parents' voices, those with autism had lower brain activity in the superior temporal gyrus, a brain region involved in language reception, compared with controls.Although this finding makes sense, we should be cautious about its interpretation. This is not an autism-detecting brain scan. Language deficits are a core and defining feature of the disorder; one doesn't need a brain scan to show this. And there are many people with language difficulties who do not have autism. Therefore, a technology that detects language problems doesn't move the ball towards a differential diagnosis.
