The thing I don't like about this is the amount of radiation exposure. They mention somewhere on the site that it's well below the levels that show a clear cancer risk, but I've seen at least one study where the incidence rate of cancer goes up slightly in populations who've had CT scans (similar amount of ionizing radiation). Basically, it's close to being x-rayed several hundred or even over a thousand times in a row. Here's a neat chart that shows how things compare: http://upload.wikimedia.org/wikipedi...ion_(xkcd).png

I'm hoping to get an MRI after my neuropsych test. I've bumped my head to the point of confusion, altered smell, and fatigue (pretty sure I've had undiagnosed concussions). I was also put under general anesthesia before age 2 for surgery, which is also correlated with ADHD, developmental problems, and auditory processing issues (things I've had to some degree).

At the very least, I think it's important to look at the brain when meds and therapy have failed miserably. I think Amen means well (I don't think he's a snake), but he doesn't even have a baseline picture for personality types. I doubt an INTJ personality will have the same activity patterns as an ESFP
