The DSM-5 is the standard tool used by clinicians to diagnose ADHD. But, it has serious shortcomings, especially for diagnosing adult ADHD.
Over the past several decades, educators, policymakers and scientists have referred to ADHD, as a national crisis and have spent billions of dollars looking into its cause. They’ve looked at genetics, brain development, exposure to toxic substances like lead, the push for early academics, and many other factors. But new studies have a number of researchers asking whether the behavior and attention issues ascribed to ADHD are due to the fact that many kids today simply don’t get the sleep they need.
