Panphobia
Look up panphobia in Wiktionary, the free dictionary.
Panophobia, also called Pamphobia, omniphobia, Pantophobia or Panphobia, is a rare medical condition in which the sufferer literally fears everything. Alternatively, it may manifest as what is known as a "non-specific fear"; the sufferer finds themself in a state of fear but with no known target, and therefore no easy remedy. It has been described as "a vague and persistent [dread] of some unknown evil" [1]. It is officially recognised by the National Institute of Health's Office of Rare Disease.
Panophobia is most frequently found as a secondary condition to schizophrenia. Hypnosis is sometimes claimed as a cure.
It should not be confused with pantaphobia; the fear of nothing.
