Psychogenic. Descriptive of mental disturbances having a psychological rather than physiological origin.
Nobody doubts that the neuroses are psychogenic. "Psychogenesis" means that the essential cause of a neurosis, or the condition under which it arises, is of a psychic nature. It may, for instance, be a psychic shock, a gruelling conflict, a wrong kind of psychic adaptation, a fatal illusion, and so on.["Mental disease and the Psyche,"CW3, par. 496.]
