Anyone who uses testing as opposed to self-report measures to diagnose ADD/ADHD knows that this is a disorder of leftovers. Leftovers are the scraps saved from a meal that may be the vegetables, the meat or main entree or even the desert. ADD has become a bin of leftovers. The diagnosis to give when a child is overly active, falling asleep in class, non-attentive, non-responsive or even a poor reader. However, the sleep world continues to document a vast assortment of sleep disorders that would account for the symptoms we so quickly assume are manifestations of an attention disorder. Case in point is the recent research article by Dr. Konofal (Relationship Between ADHD and Sleep Disturbances, Int. J Sleep Wakefulness, Vol 1 No.3, 2008) who points to disorders such as Restless Legs Syndrome (RLS) Delayed Sleep Phase Syndrome, Sleep apnea, and I would add Periodic Limb Movements in Sleep and childhood insomnia as precursors to daytime hyperactivity and inattentiveness. Sleepy children are hyperactive children, a well known documented fact. Sleepy children are inattentive, another well known fact. We really need to do our homework and use testing (neuropsychological evaluation from my perspective) to document a disorder such as ADD or ADHD before jumping to an incorrect conclusion and incorrect treatment.
