Could it be possible that the Krisiloff Diet can cure ADHD ( Attention Deficit/ Hyperactivity Disorder) ?

I read interesting article yesterday in New York Times. some people believe that ADHD is linked to sleep disorders.If this is true we already know that people on caffeine never achieve the deepest levels of sleep.People on the Krisiloff Diet must eliminate caffeine and tell me all the time how much better they feel because they sleep so much better.
