Hysteria is a term used colloquially to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the nineteenth century, female hysteria was considered a diagnosable physical illness in women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the twentieth century, it shifted to being considered a mental illness. Many influential people such as Sigmund Freud and Jean-Martin Charcot dedicated research to hysteria patients.Currently, most physicians do not accept hysteria as a medical diagnosis. The blanket diagnosis of hysteria has been fragmented into myriad medical categories such as epilepsy, histrionic personality disorder, conversion disorders, dissociative disorders, or other medical conditions. Furthermore, lifestyle choices, such as choosing not to wed, are no longer considered symptoms of psychological disorders such as hysteria. Source: Wikipedia (en)
