Anorexia nervosa (AN) is a psychiatric disorder primarily characterized by "restriction of energy intake relative to requirements leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health" (DSM-5, n.d.). Here, we propose a novel interpretation of food restriction of AN, which elaborates on recent accounts of the brain as a predictive machine, continuously inferring and controling incoming signals, including bodily signals - i.e., interoceptive (active) inference. In this perspective, the extreme eating restrictions characterizing AN may serve the fundamental role of keeping under control (i.e., reducing excessively high levels of) interoceptive uncertainty, above and beyond controlling and mitigating concerns for body weight. In other words, noisy interoceptive streams may instantiate active strategies (i.e., eating restrictions) that amplify autonomic hunger signals, to minimize interoceptive uncertainty and maintain a more coherent sense of (interoceptive) self.

保持您的感知流受控:对神经性厌食症的积极推断观点。

神经性厌食症(AN)是一种精神疾病,其主要特征是“相对于年龄,性别,发育轨迹和身体健康而言,能量摄入量相对于需求显着降低的要求受到限制”(DSM-5,第nd)。在这里,我们提出了一种关于AN的食物限制的新颖解释,该解释详细说明了作为预测机器的大脑的最新情况,不断地推断和控制包括身体信号在内的传入信号,即,感知(主动)推理。从这个角度来看,表征AN的极端饮食限制可能起着基本作用,即控制和减轻对体重的担忧,可以控制(即降低过高的水平)感觉不确定性。换一种说法,
