Psychiatric
Circa 1550 BCE — Edwin Smith Papyrus, ancient Egypt; ancient Greek literary sources referencing Pan
The experiences now classified as panic disorder were interpreted through radically different frameworks across centuries, including demonic possession, cardiac disease, and nervous system weakness before the condition acquired a distinct psychiatric identity in the twentieth century. Ancient and medieval physicians attributed sudden overwhelming episodes of fear and physical distress to supernatural forces, humoral imbalances, or disorders of organs such as the heart and uterus. The gradual separation of these episodes from broader categories of hysteria, neurasthenia, and anxiety represented a long conceptual process that intersected with the development of psychiatry as a medical discipline.
Historical Narrative
Among the oldest textual records describing sudden, overwhelming episodes of terror with accompanying physical sensations are passages in ancient Egyptian and Mesopotamian literature that attributed such states to divine punishment or demonic intrusion. The Edwin Smith Papyrus and various Mesopotamian medical tablets contain references to conditions in which individuals were seized without warning by states of extreme fear, and healing rituals performed by priests and physicians alike were oriented toward appeasing supernatural forces believed to be responsible.
The word 'panic' itself derived from the ancient Greek deity Pan, whose sudden appearances in lonely places were said to cause inexplicable, overwhelming terror in travelers and soldiers. This mythological association reflected a widely held ancient understanding that such episodes arrived from outside the person rather than arising from within the body or mind. Hippocratic physicians did attempt to naturalize these experiences within humoral theory, attributing sudden fearful states to an excess of black bile, which was believed to darken the spirit and produce irrational terrors. Treatments prescribed within this framework included dietary modification, exercise, warm baths, and the administration of hellebore.
Galen elaborated significantly on the Hippocratic nervous system, proposing that the heart, brain, and liver each governed different aspects of mental and physical life, and his influence shaped European medical thinking about emotional disturbances for over a millennium. Medieval physicians, both in Islamic medical traditions shaped by Avicenna and Ibn Rushd and in European scholastic medicine, continued to work within modified Galenic frameworks, often attributing sudden paroxysms of fear to vapors rising from diseased organs — particularly the uterus in women, giving rise to the long-standing diagnosis of hysteria. Male patients experiencing similar episodes were more often described under terms relating to melancholia or hypochondria, with the latter originally referring literally to disorders arising from beneath the cartilage of the chest.
The seventeenth and eighteenth centuries brought significant attention to what physicians began calling 'the spleen,' 'the vapors,' or 'nervous disorders,' as emerging natural philosophy generated new interest in the nervous system as a physical structure. Thomas Willis and Thomas Sydenham in England contributed influential accounts of nervous and hysterical disorders, and Sydenham notably argued that many such conditions were not confined to women, challenging the uterine framework. George Cheyne's popular 1733 work 'The English Malady' framed nervous disorders as conditions particularly afflicting refined and sensitive persons, introducing a cultural dimension that associated nervous vulnerability with social class and education.
The nineteenth century brought major reconceptualization through the work of neurologists and early psychiatrists. Benjamin Rush in the United States and Philippe Pinel in France advanced more systematic clinical approaches to mental and nervous conditions. Jean-Martin Charcot's investigations at the Salpêtrière in Paris brought renewed attention to paroxysmal nervous states, and his influence on Sigmund Freud proved consequential. Freud himself identified what he called 'anxiety neurosis' as a distinct clinical entity in an 1895 paper, separating it from neurasthenia and arguing that it had specific psychological origins, particularly in undischarged sexual tension. This framework dominated psychiatric thinking about episodic anxiety for much of the early twentieth century.
The formal separation of panic disorder as a discrete diagnostic category emerged through the work of Donald Klein in the 1960s, who observed that patients with spontaneous panic attacks responded differently to pharmacological intervention than those with generalized anxiety, suggesting a distinct underlying process. This clinical observation contributed to the eventual separation of panic disorder as a distinct entity in formal diagnostic classification systems, marking the culmination of a conceptual journey spanning millennia.
