This article challenges the definition of ADHD as a legitimate medical condition and argues it may instead be a culturally constructed myth. The author provides evidence that ADHD diagnoses have increased dramatically in the US without clear scientific evidence that it is a neurological disorder. No biological tests can confirm ADHD, and rates of diagnosis vary widely between countries. The author suggests economic and cultural factors may better explain the rise in ADHD diagnoses in America than it representing a real neurological condition.
