In 1897 Ganser (1) gave a lecture entitled “Ueber einen eigenartigen hysterischen Dämmerzustand.” This has been translated literally as on “A specific hysterical twilight state,” which we consider unfortunate, as in keeping the words it loses the sense of the original, for the notion of a twilight state remains foreign to us, and is better rendered as a “dimming of consciousness” or “clouding of consciousness.” Further, the concept of hysteria has changed considerably since then and his cases would now be regarded as psychotic.
