I've read elsewhere that ADHD has numerous causes.  Some kids diagnosed are simply overactive kids in the classroom (usually boys) who are restless sitting still. Some kids have so little exercise that they're too jumpy to sit still (also usually boys).  Some are eating such bad food and so much sugar in juices and pops, that they're hyper.  And finally, there is probably the few (not 1 in 20) who actually have a serious problem.

All of this is treated with medication instead of probing for deeper causes. Now these kids, in addition to Ritalin are being prescribed anti-psychotics!  Sensibly this article at one point states that perhaps these kids should go and run around... but the concluding statement is like a shrug saying, what the heck, pills are easier.  And someone gets too make money selling them too.  

Disgusting and dangerous.
