[Hysteria: problems of definition and evolution of the symptomatology].

What is the evolution of hysteria, now that the spectacular crises of previous times tend to occur less frequently? Are hysterical manifestations disappearing or do they take other forms? This question raises semantic and phenomenological problems concerning hysteria. A review of the literature shows the complexity and precariousness of some definitions, the question raised by associated organic disorders and the compounding influences of other nosological entities, such as depression and psychosomatic disorders. Clinical histories from the records of a psychiatric hospital for the period 1910-1929 were compared with those for the period 1970-1980. The results of the study were surprising with respect to the similarity of epidemiological profiles. If it can be concluded that hysterical manifestations are not disappearing, then the study confirms the evolution of symptomatology which, especially in women, takes atypical forms of depressive, neurovegetative or psychosomatic disorders. In males, hysterical symptoms are of a more acute nature and frequently occur in dependent, immature or infantile personalities, whilst in the past they were more chronic and frequently associated with more serious personality disorders.
