撰文 | 英成 暴食症(binge eating disorder, BED)是常见的饮食失调症之一,会导致肥胖、生活质量下降和短寿【1】。大多数针对肥胖的诊疗策略往往治标不治本,即使是减重手术也无法完全改善暴食症【2】。相关动物模型的结果显示,脑伏隔核的电生理活性和暴食相关行为有明确的关联,短暂的高频电刺激可显著降低小鼠的暴食行为【3】,但持续刺激则会降低疗效【4-5】。这些证据表明,类似的干预策略有一定的临床应用价值,值得临床探索性研究。 近日,宾夕法尼亚大学Casey H. Halpern课题组在Nature Medicine上发表题为Pilot study of responsive nucleus accumbens deep brain stimulation for loss-of-control eating的探索性研究,在2名入组患有暴食症的严重肥胖志愿者中,发现靶向伏隔核的脑深部电刺激技术可改善食物摄入量和体重,为后续更大规模的临床研究奠定了基础。
