title: Clinical management of Gulf War veterans with medically unexplained physical symptoms.
abstract: Veterans of the Persian Gulf War have increased rates of medically unexplained physical symptoms (MUPS). This article describes a model for the clinical management of MUPS in Gulf War veterans. Predisposing, precipitating, and perpetuating factors contribute to the emergence and clinical course of MUPS. Predisposing factors include biologically and psychosocially determined vulnerabilities that render individuals more susceptible to MUPS and related morbidity. Precipitating factors promote the onset of MUPS. These factors are triggering events that serve to initiate episodes of MUPS. Perpetuating factors sustain illness. They maintain, exacerbate, or prolong MUPS and associated distress and disability. Intervention involves identifying and addressing all relevant predisposing, precipitating, and perpetuating factors. A representative patient vignette is presented to illustrate the clinical utility of the model for a Gulf War veteran with MUPS.
