Chronic Hallucinatory Psychosis (CHP) is a disease that has long been considered in the French literature, but is neglected by the current Anglo-Saxon classification systems, which generally classifies it among the atypical forms of Schizophrenia.Various authors have described the disorder, attributing it different characteristics. In 1911, Gilbert Ballet (1985) first described CHP, which has been subsequently considered by De Clérambault (1923), Ey (1934) and Pull (1987). These Authors underlined the central nature of the hallucinatory symptoms and suggested the nosographic autonomy of the syndrome, but each hypothesized different underlying pathogenetic mechanisms and disagreed about the prognosis.The French concept of "Psychose Hallucinatoire Chronique" is characterized by late-onset psychosis, predominantly in females, with rich and frequent hallucinations, but almost no dissociative features or negative symptoms.We propose the definition of "Hallucinatory Disorder" (HD) in order to underline the differences between the clinical picture we observed and the psychopathological profile of Chronic Hallucinatory Psychosis proposed by the French Authors.Auditory verbal hallucinations are the prevalent psychopathological phenomena in HD, appearing in the absence of other types of hallucinations and of thought or behavioral disorganization.
