Your Health October 30, 2013 ADHD and sunlight

Birmingham, AL -

  Could sunlight have an impact on the prevalence of attention-deficit hyperactivity disorder (ADHD).
    Research indicates regions that got the most sun had rates of ADHD diagnoses that were about half as high as regions that got the least sunlight.
     In the United States, the sunniest states were in the Southwest and West.  They included Arizona, California, Colorado, Nevada, New Mexico and Utah. Rates of ADHD diagnoses in those states ranged from 6 percent to 8 percent.  In the darkest states, which included a swath of the Northeast, rates of ADHD ranged from 10 percent to 14 percent.
     At least one other expert says he's not sure melatonin is the best explanation.
     The findings appear in the Oct. 15 issue of the journal, Biological Psychiatry.
