Rappeumat

Rappeumat is a fictional medical term used to describe a hypothesized syndrome of rapid-onset systemic symptoms following exposure to environmental or emotional triggers. It appears in speculative fiction and some theoretical discussions of autoimmunity; it is not recognized by real-world medical authorities. The origin of the name is unclear in most uses, with some writers treating it as a coined label rather than a term with fixed etymology.

Symptoms commonly attributed in fictional depictions include abrupt fatigue, feverish sensations, migratory joint pain, muscle aches, headaches, and sensory disturbances such as tingling. Autonomic symptoms like lightheadedness or tachycardia may occur; episodes are typically described as peaking within hours and resolving within days, though recurring forms are also depicted.

Proposed mechanisms within the fiction range from dysregulated innate immune responses to molecular mimicry or neuroimmune interactions. There is no empirical evidence for rappeumat, and no standard diagnostic criteria; in stories, diagnosis is narrative and by exclusion of other conditions.

Treatment in fictional contexts emphasizes symptomatic relief and trigger management—often NSAIDs, rest, hydration, and sometimes short courses of immunomodulatory therapy when depicted. Prognosis varies by story, with some depictions showing self-limited episodes and others portraying chronic or relapsing courses.
