Coma [SEP] Etymology
The term 'coma', from the Greek "koma", meaning deep sleep, had already been used in the Hippocratic corpus ("Epidemica") and later by Galen (second century AD). Subsequently, it was hardly used in the known literature up to the middle of the 17th century. The term is found again in Thomas Willis' (1621–1675) influential "De anima brutorum" (1672), where lethargy (pathological sleep), 'coma' (heavy sleeping), "carus" (deprivation of the senses) and apoplexy (into which "carus" could turn and which he localized in the white matter) are mentioned. The term "carus" is also derived from Greek, where it can be found in the roots of several words meaning soporific or sleepy.
