Is Hyperactivity for Real?

The opening paragraphs of an article in The New York Times:

Nearly one in five high school age boys in the United States and 11 percent of school-age children over all have received a medical diagnosis of attention deficit hyperactivity disorder, according to new data from the federal Centers for Disease Control and Prevention.

These rates reflect a marked rise over the last decade and could fuel growing concern among many doctors that the A.D.H.D. diagnosis and its medication are overused in American children.

The figures showed that an estimated 6.4 million children ages 4 through 17 had received an A.D.H.D. diagnosis at some point in their lives, a 16 percent increase since 2007 and a 53 percent rise in the past decade. About two-thirds of those with a current diagnosis receive prescriptions for stimulants like Ritalin or Adderall, which can drastically improve the lives of those with A.D.H.D. but can also lead to addiction, anxiety and occasionally psychosis.

An abstract for some notes I wrote up a few years ago, Music and the Prevention and Amelioration of ADHD: A Theoretical Perspective:

Russell A. Barkley has argued that ADHD is fundamentally a disorientation in time. These notes explore the possibility that music, which requires and supports finely tuned temporal cognition, might play a role in ameliorating ADHD. The discussion ranges across cultural issues (grasshopper vs. ant, lower rate of diagnosis of ADHD among African-Americans), play, distribution of dopamine and norepinephrine in the brain, neural development, and genes in culture (studies of the distribution of alleles for dopamine receptors). Unfortunately, the literature on ADHD does not allow us to draw strong conclusions. We do not understand what causes ADHD nor do we understand how best to treat the condition. However, in view of the fact that ADHD does involve problems with temporal cognition, and that music does train one’s sense of timing, the use of music therapy as a way of ameliorating ADHD should be investigated. I also advocate conducting epidemiological studies about the relationship between dancing and music in childhood, especially in early childhood, and the incidence of ADHD.
