Also known as Hysteria
Hysteria, in its colloquial use, describes unmanageable emotional excesses. People who are "hysterical" often lose self-control due to an overwhelming fear that may be caused by events in one's past that involved some sort of severe conflict. The fear can be centered on a body part, or most commonly, on an imagined problem with that body part. Disease is a common complaint; see also body dysmorphic disorder and hypochondriasis. Generally, modern medical professionals have given up the use of "hysteria" as a diagnostic category, replacing it with more precisely defined categories such as somatization disorder. In 1980, the American Psychiatric Association officially changed the diagnosis of "hysterical neurosis, conversion type" to "conversion disorder".Source: Wikipedia
