It is clear that patients with anorexia nervosa and bulimia have disturbances of mood, and it is likely that the mood disturbances bear an important relationship to the disturbances of eating behavior. We have as many questions, however, about the relationship between mood and eating behavior in these syndromes as we have answers. Although patients with anorexia nervosa and bulimia are frequently depressed, they fail to exhibit many of the biological characteristics of typical depressive illness, suggesting that these eating disorders are probably not simply variants of depression. Patients with bulimia appear to binge in response to dysphoric emotional states and to derive some transient relief from their bingeing. But it is unclear what facet or facets of the binge produce the alteration in emotional state, and thereby may serve to reinforce the behavior. A more detailed examination of this issue may significantly advance our understanding of the relationship between mood and food in eating disorders.
显然，神经性厌食症和贪食症患者存在情绪障碍，而且情绪障碍很可能与饮食行为障碍有着重要关联。然而，对于这些综合征中情绪与饮食行为之间的关系，我们的疑问和答案一样多。尽管神经性厌食症和贪食症患者常常抑郁，但他们并未表现出典型抑郁症的许多生物学特征，这表明这些饮食失调症可能并非仅仅是抑郁症的变体。贪食症患者似乎会因烦躁情绪状态而暴饮暴食，并从暴饮暴食中获得一些短暂的缓解。但尚不清楚暴饮暴食的哪个方面或哪些方面会导致情绪状态的改变，进而可能强化这种行为。对这个问题进行更详细的研究可能会显著增进我们对饮食失调症中情绪与食物关系的理解。
