Various aspects of hysteria namely historical consideration, aetiology, diagnosis, clinical features and treatment have been discussed. Hysteria is only a symptom and not a disease. Slater (1961) argues that the absence of any strong genetic or familial element of any single perdisposed personality type, or any specially effective form of treatment, and with the evidence of antecedent and subsequent histories not of hysteria but of other psychiatric syndromes, all these factors justify the view that hysteria is not merely a phenomenon which can occur both in health and in illness.
