Proffeser Karen Pine conducted a study on children with attention problems, such as ADD, and ADHD. She used the idea of electroencepholalography, which is basically just electronics controlled by brain waves. She set up an educational computer game for the children, and put on a helmet that picked up these brain waves. Every time they lost concentration on the game, it stopped, so this encouraged them to stay focused.
This is a huge discovery for something that is considered a minor problem in the US. Too many children today run the risk of developing one of these diseases, and this could be a huge step in discovering a cure.
