Page "Psychosis" Paragraph 91

The word was also used to distinguish disorders which were thought to be disorders of the mind, as opposed to " neurosis ", which was thought to be a disorder of the nervous system.

The psychoses thus became the modern equivalent of the old notion of madness, and hence there was much debate on whether there was only one ( unitary ) or many forms of the new disease.

One type of broad usage would later be narrowed down by Koch in 1891 to the ' psychopathic inferiorities ' - later renamed abnormal personalities by Schneider.
