I spoke to my DS's doctor about VT, he said he has seen it work a couple of times, but far more often it doesn't work. He wasn't sure why it did work in the situations that it did. When I read further it appears to be good for a couple of conditions, but often people think VT is a silver bullet and it will fix things that it won't fix.

I called one VT in my area, and I asked the person who answered how often they find problems when they do the initial evaluation, and she implied they always found problems�.so that put me off. Statistically it doesn't make sense that they would always find problems...
