Autism brain scan hype - some evidence-based good thinking to the rescue

I've found a piece written by someone who understands stats and critical thinking of the evidence-based medicine type which takes apart the recent media hype about a study of autism diagnosis using brain scans. It pretty much goes over the same points that I made in my blog post on this subject dated August 11th, but Mr Heneghan explains it more clearly and in more detail. I recommend that you read this:

"Why autism can't be diagnosed with brain scans: Using brain scans to detect autism would be a huge expensive waste of money"
