Alex Moore notices that caffeine withdrawal is listed as a mental disorder in the new DSM-5:
Withdrawal “conditions are considered mental disorders when they impair a person’s ability to function in daily life,” writes the Wall Street Journal. It’s not exactly clear to me why this is being classified as mental disorder rather than just a physiological reaction. But if you’ve ever felt caffeine withdrawal, “impairing a person’s ability to function in daily life” is not hyperbole.
Caffeine withdrawal was upgraded from its previous status as pending in the last DSM. Researchers have concluded that in order to have full-on caffeine withdrawal a person needs to experience at least “three of five symptoms within 24 hours of stopping or reducing caffeine intake: headache, fatigue or drowsiness, depressed mood or irritability, difficulty concentrating, and flulike symptoms such as nausea or muscle pain.”
