Scott compares ancient and modern descriptions of bipolar disorder, finding significant similarities that suggest the condition is biologically grounded rather than culturally determined.
Longer summary
Scott Alexander discusses the concept of culture-bound syndromes and the risk of American mental health norms being imposed globally. He then compares the ancient description of bipolar disorder by Aretaeus of Cappadocia to modern diagnostic criteria. Scott matches symptoms from current questionnaires (Mood Disorder Questionnaire and Patient Health Questionnaire-9) with Aretaeus' descriptions, finding significant overlap. He concludes that the similarities between ancient and modern descriptions of bipolar disorder suggest it is a biologically grounded condition rather than a culture-bound syndrome.
