Multiple Chemical Sensitivities–A Syndrome of Pseudotoxicity Manifest as Exposure Perceived Symptoms

Abstract

The history of and nomenclature of the multiple chemical sensitivities are reviewed. The author's definition of multiple chemical sensitivity is a symptom complex 1) triggered by odor or a perceived exposure; 2) occurring at exposure levels below those of allergic sensitivity or irritation; 3) analogous to the symptoms of panic disorder as defined by DSM-IV-R; 4) lacking objective clinic pathologic criteria; and 5) responsive to panic disorder management.
