"In The Irritable Heart Jeff Wheelwright profiles five ailing veterans, unraveling the health mystery through their intimate and fascinating case histories. He describes the veterans' experiences, beginning with their deployment to the Gulf and tracking them through their return, their mysterious suffering, and their struggles to find the reasons for their illnesses." "Drawing on his experiences as a reporter in the Gulf in 1991, he reviews the toxic substances in the environment, such as oil smoke and nerve gas, that many believe to be the cause of the conditions. Wheelwright demonstrates why such scenarios are unlikely. Rather, he shows that the gulf war illnesses belong in the company of chronic fatigue syndrome, fibromyalgia, and multiple chemical sensitivity - symptom complexes that are increasing in America and evading a biomedical explanation. Although these contemporary illnesses are unrelated to war, Wheelwright points out that the gulf war ills have their own precedents in military history as far back as a Civil War malady known as "irritable heart.""--BOOK JACKET.
