Forms

epilēpsia f (genitive epilēpsiae); first declension[1][2] Late and medieval texts spell it epilempsia, epilemsia and epilensia.[3][4] Theodorus Priscianus has the by-form epilēpsis.[1]

Etymology

It is borrowed from Ancient Greek ἐπιληψία (epilēpsía, “epilepsy”).[2][1][4] The DMLBS gives ἐπίληψις (epílēpsis) beside it as the source.[5] The Greek noun means literally “a seizure” and comes from ἐπιλαμβάνω (epilambánō, “to lay hold of, seize upon”).[6][7]

Earliest recorded meaning

The TLL records it, spelt with ⟨-lens-⟩ in the manuscripts, in the Mathesis of Firmicus Maternus,[3] written in 343–350 AD.[7] It names the falling sickness.[3]

Semantic evolution

The word was a Greek medical term beside the native Latin name morbus comitialis.[2][1] Lampridius uses it in the life of Heliogabalus, and Caelius Aurelianus discusses it at length among the chronic diseases;[2][1] Vegetius applies it to cattle.[2]

In medieval Latin it remained the ordinary medical name of the disease, in many spellings: the Salerno glosses describe it as a blockage of the chief ventricles of the brain.[4] Through French épilepsie it reached English.[6]
