英語時(shí)差：如何診斷孤獨(dú)癥（下）

W: But a brain scan could change that. The researchers, at King’s College Institute of Psychiatry in London, studied 59 adult males, 20 with autism, 19 with ADHD, and 20 with normal brains.First they evaluated them with standard IQ tests and interviews. Then the researchers scanned their brains.The scans were 90% accurate in recognizing which subjects had autism. M: That’s because the brains of people with autism tend to have structural differences in parts of the frontal and parietal lobes–areas of the brain involved in behavior and language. W: The scan needs more testing before it’s put to widespread use. But if it pans out, the scan could help doctors diagnose autism more quickly and more accurately. And that, in turn, could lead to earlier and more effective therapies.
