Eclampsia, the occurrence of convulsions in pregnant or recently delivered women, was documented by ancient civilizations and attributed for centuries to supernatural causes, humoral imbalance, or the mysterious influence of the womb on the nervous system. The gradual disentangling of eclampsia from epilepsy and other convulsive disorders occupied physicians across multiple centuries. Its history reflects the slow evolution of obstetrics from a craft tradition into a scientific discipline.
Historical Narrative
The earliest detailed descriptions of convulsions occurring in pregnant women appear in ancient Egyptian medical texts, most notably the Kahun Papyrus dating to approximately 1900 BCE, which references uterine disturbances accompanied by alarming systemic events. The Edwin Smith Papyrus and later the Ebers Papyrus also contain references to conditions recognizable in retrospect as obstetric emergencies. Ancient Egyptian physicians attributed such episodes to movements of the uterus through the body — a theory that would echo through Greek and Roman medicine for centuries.
Hippocrates and his followers in the fifth and fourth centuries BCE grouped convulsions in pregnancy under broader discussions of epilepsy and uterine disorder, noting that seizures in this context carried a particularly grave prognosis. The humoral explanation held that an accumulation of cold, phlegmatic matter — or alternatively a surfeit of black bile — could provoke convulsive episodes. Soranus of Ephesus, writing in the second century CE and widely considered the most systematic ancient authority on gynecology, offered detailed descriptions of obstetric convulsions and distinguished them from epilepsy on largely observational grounds, though his explanatory framework remained humoral.
Throughout the medieval period, Islamic physicians including Avicenna incorporated Greek frameworks into encyclopedic medical texts that remained authoritative in both the Islamic world and later in European universities. Convulsive conditions in pregnancy were discussed within chapters on uterine disorders and broadly connected to theories of humoral excess and nervous excitability. The womb was thought to exert a powerful and sometimes malevolent influence on the brain and nervous system, a concept that shaped obstetric thinking well into the early modern era.
The word eclampsia itself derives from the Greek word for a sudden flash or appearance, and its adoption as a distinct clinical category began gathering momentum in the seventeenth and eighteenth centuries. François Mauriceau, the influential French obstetrician of the seventeenth century, provided careful descriptions of convulsions in parturient women and attempted to move the discussion toward more anatomical explanations. The eighteenth century saw the emergence of lying-in hospitals across Europe, which, despite their often-lethal infection rates, also allowed physicians to observe and record obstetric emergencies more systematically than had been possible in dispersed home births.
The landmark conceptual separation of eclampsia from epilepsy and other convulsive states was advanced significantly in the early nineteenth century by French physician François Boissier de Sauvages de Lacroix and later by Eduard von Siebold, who compiled historical and clinical observations into the first dedicated monograph on the subject. John Charles Weisse and other European clinicians in the mid-nineteenth century began connecting convulsions in pregnancy with observations about urine quality, laying early groundwork for the eventual understanding of the condition's relationship to kidney function and protein in the urine — though the full physiological picture would not emerge until the late nineteenth and early twentieth centuries through the work of researchers including Leon Labeille and later John William Ballantyne, who helped establish the study of antenatal pathology as a serious medical discipline.
