All very interesting.

I have had a couple of brain scans (MRI's) in my adult life. I had one about 3 years ago. I've also had an EEG because of suspected seizure activity. None showed up, but the tech told me it's very difficult to detect seizure activity unless it actually occurs during the test.

I am guessing that the testing has everything to do with money. In other words, if basic blood work in done and comes out normal doctors don't usually go on to further testing. I know my insurance sure wouldn't allow it.

I'm still not convinced, though, about psych meds and brain chemistry. Being able to accurately measure neurochemicals certainly contradicts what every pdoc I've spoken with has told me...and that's a lot of pdocs.
