A term coined in or shortly before 1900, possibly by the German neurologist Carl Wernicke (1848-1904), to denote a mental state or disorder in which hallucinations feature prominently. The term hallucinosis has been variously defined as
   1) a mental state characterized by continual hallucinations,
   2) an abnormal condition or mental state characterized by hallucinations,
   3) a psychiatric disorder involving hallucinations,
   4) a syndrome, usually of organic origin, characterized by more or less persistent hallucinations,
   5) a transient hallucinatory state accompanied by a clear sensorium and/or proper insight into its nature, and
   6) a delusional state triggered by hallucinations (as in * hallucinosis phantastica).
   The French psychiatrist Henri Ey (1900-1977) follows his compatriot Henri Charles Jules Claude (1869-1946) and the German psychiatrist Paul Schröder (1873-1941) in characterizing hallucinosis as a hallucination, the false nature of which is recognized by the affected individual. Aware of the multiple connotations of the term hallucinosis, Ey proposes that it be replaced by *hallucinotic eidolia (éidolie hallucinosique). Wernicke, however, uses the term hallucinosis to denote the clinical picture of *paranoia hal-lucinatoria, as well as in the context of notions such as * acute hallucinosis, *chronic hallucinosis, and chronic hallucinosis of alcoholics (i.e. *alcoholic hallucinosis). Some additional examples of * hallucinosic syndromes described in the literature are * algohallucinosis, * brainstem auditory hallucinosis, *chronic tactile hallucinosis, *cocaine hallucinosis, *crepuscular hallucinosis, *experiential hallucinosis, *experiential thalamic hallucinosis, * functional hallucinosis, *hallucinosis phantastica, *narcotic hallucinosis, *organic hallucinosis, * peduncular hallucinosis, *persistent hallucinosis, and *syphilitic hallucinosis.
