FYI before you watch an 80 minute video (which I did):
"Amen has built a profitable business around the use of SPECT (single photon emission computed tomography) imaging for purported diagnostic purposes.[6] His marketing of SPECT scans and much of what he says about the brain and health in his books, media appearances, and marketing of his clinics has been condemned by scientists and doctors as lacking scientific validity and as being unethical, especially since the way SPECT is used in his clinics exposes people to harmful radiation with no clear benefit."
As a european, it is sad to see, that the health system in the US is geared towards profit.
I wonder what the parents of one of his youngest patients (below ten IIRC) would say to those scientists and doctors about "no clear benefits". Their son showed abnormal behaviour, drawing notebooks full of pictures of him killing his classmates. The brainscan revealed a huge brain tumor. Amen had to call several brain surgeons, till he found one who was willing to operate the child. After the removal of the tumor his behaviour normalised.
You don't save time by listening to only one side and forming an unbalanced opinion. One reason i like HN so much, is that you can read a debate and get both sides of the coin.
