NEUROBIOLOGY OF FEEDING BEHAVIOR IN BULIMIA AND ANOREXIA NERVOSA

神经性贪食症是一种病因不明的进食障碍， 通常发生在正常体重的女性身上。 这些女人放纵和净化 并且经常有情绪和能量平衡的紊乱。 生病的时候， 神经性贪食症的女性已经被发现有一些改变， 神经递质系统（去甲肾上腺素，血清素，肽YY（PYY）， β-内啡肽和胆囊收缩素（CCK））。 没有研究评估了 这种干扰可能会在恢复后持续存在，因此， 可能与特质有关 我们将研究 神经递质的改变病理喂养，以及情绪和 能量平衡，在BN和确定是否神经递质紊乱 与状态和/或特质相关。

Bulimia nervosa is an eating disorder of unknown etiology that most commonly occurs in women at normal weight. These women binge and purge and often have disturbances of mood and energy balance. When ill, bulimia nervosa women have been found to have alterations of a number of neurotransmitter systems (norepinephrine, serotonin, peptide YY (PYY), beta-endorphin, and cholecystokinin (CCK)). No studies have assessed the possibility that such disturbances may persist after recovery and thus are potentially trait-related. We will study the relationship of neurotransmitter alterations to pathological feeding, as well as mood and energy balance, in BN and determine whether neurotransmitter distrubances are state-and/or trait related.
