David, The beta excess subgroup of ADHD represents about 10% to 20% of the ADD/ADHD population, depending on the study... Chabot, or Clark's studies are probably the best two on this topic. Beta spindles can also be from medications, like Valium, Xanax, Ativan, sedatives/barbiturates, and most sleeping medications. regular beta can be increased by stimulants and antidepressants too.
