> Autism isn’t diagnosed by blood tests or imagining like you might expect from simpler disorders. I, perhaps incorrectly, understand a diagnostic test for ASD to be something involving a lot of interaction between the patient and the professionals analyzing the patient’s behavior and described thought processes. That process isn’t perfect but it can work. The brain imaging method seems more robust in theory. As you point out (thanks for the details!), it’s not particularly advanced and may not be effective in the long run but my hopes are still high for it. It may be a long way off but a future generation might have access to a less costly and more accurate test. I guess calling the current process a “test” seems off?
