The problem of Gulf War syndrome

Following a war with widespread attention to and concern over the potential for numerous biological and chemical warfare exposures, some Gulf War veterans returned home and developed various illnesses. Although some of these illnesses are readily diagnosable, the so-called Gulf War syndrome has remained a controversial and nebulous diagnosis. It is characterized by multiple, subjective symptoms, and by a lack of objective pathology. To date, the search for a single disease entity and a biological model to explain this illness has been unsuccessful. Wars have long affected the health of veterans in multiple ways, and a single disease entity is not likely as a viable explanation for these outcomes. Given the nature of the illness, and its overlap with many other controversial chronic illnesses, we suggest that the biopsychosocial model may provide a better solution to this diagnostic conundrum.
