"Natural solutions" are not always simple, and certainly aren't with this one.

It's similar to obesity in that it's largely a consequence of advanced capitalist culture. Which doesn't make it easy for people to opt out of the lifestyles that keep the profit system profitable. One of the most effective ways to deal with ADHD is to restructure the child's time, so it gets more sleep and less distracting external and chemical stimuli. Now try reordering your life to cut out TV programmes the whole family has been watching for years, prevent a kid using a video console it only got upgraded last birthday, find a source of additive-free drinks at an affordable price, find a new school so the kid can walk to it, find the kid a network for new friends that don't need mobiles to keep in touch with other. Chances are you will need to do *most* of those and then some. This is far beyond what most parents of ADHD kids can manage on the resources they've got.

One particularly twisted wrinkle on it: in some regions, parents can get substantial financial benefits for having an officially diagnosed ADHD child. Enough to make a real difference to the family budget. The parent can get the child stabilized by environmental and dietary interventions, then realize, shit, the money's dried up. So a couple of months later the kid is back on the diet Irn Bru and hours a day on the PSP, in between bouts of tearing the house apart and window-smashing tantrums at school. But see how the money rolls in. (Just to be clear, this is not some Daily Mail rant about "benefit scroungers", I just happen to know it happens with this condition, and where).
