It is important to distinguish panophobia from (sometimes used interchangeably). Historically, pantophobia was a 19th-century clinical term for a “fear of everything” as a symptom of severe anxiety or psychosis, while panophobia is often described as a vague, existential dread without a clear focal point. Modern psychiatry does not formally list either in the DSM-5; instead, such symptoms are typically classified under unspecified anxiety disorder or agoraphobia (fear of open or crowded spaces where escape might be hard).
