Abstract

Obesity represents one of the wellness diseases concurring to increase the incidence of diabetes, cardiovascular diseases, and cancer. One of the main perpetuating factors of obesity is food craving, which is characterized by an urgent desire to eat a large and various amount of food, regardless of calories requirement or satiety signals, and it might be addressed to the alteration of the dorsolateral prefrontal cortex (DLPFC) activity. Despite most of the gold-standard therapies focus on symptom treatment only, non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) could help treat overeating by modulating specific neural pathways. The current systematic review was conducted to identify whether convergent evidence supporting the usefulness of tDCS to deal with food craving are present in the literature. The review was conducted by searching articles published up to January 1st 2022 on MEDLINE, Scopus and PsycInfo databases. We included studies investigating the effects of tDCS on food craving in subjects affected by overweight and obesity. According to eligibility criteria, 5 articles were included. Results showed that tDCS targeting left DLPFC with unipolar montage induced ameliorating effects on food craving. Controversial results were shown for the other studies, that might be ascribable to the use of bipolar montage, and the choice of other target areas. Further investigations including expectancy effect control, larger sample sizes and follow-up are needed to support more robust conclusions. To conclude, tDCS combined with the use of psychoeducative intervention, diet and physical activity, might represents a potential to manage food craving in individuals with overweight and obesity.

经颅直流电刺激对肥胖和超重个体食物渴望和食物摄入的影响:对其影响程度的小型回顾。
肥胖是同时增加糖尿病、心血管疾病和癌症发病率的健康疾病之一。肥胖的主要持久因素之一是对食物的渴望,其特征是迫切渴望吃大量各种各样的食物,而不考虑卡路里需求或饱腹感信号,这可能与背外侧前额叶皮层(DLPFC)活动的改变有关。尽管大多数黄金标准疗法只关注症状治疗,但非侵入性脑刺激技术,如经颅直流电刺激(tDCS)可以通过调节特定的神经通路来帮助治疗暴饮暴食。目前进行的系统回顾是为了确定文献中是否存在支持tDCS处理食物渴望的有用性的趋同证据。检索截至2022年1月1日在MEDLINE、Scopus和PsycInfo数据库上发表的文章。我们纳入了调查tDCS对超重和肥胖受试者对食物渴望的影响的研究。根据入选标准,共纳入5篇文章。结果表明,tDCS以单极蒙太奇的方式靶向左DLPFC可诱导对食物渴望的改善作用。有争议的结果显示了其他的研究,这可能是由于使用双相蒙太奇,和其他目标区域的选择。需要进一步的调查,包括期望效应控制,更大的样本量和随访,以支持更有力的结论。综上所述,tDCS与心理教育干预、饮食和体育活动相结合,可能代表了一种控制超重和肥胖个体对食物渴望的潜力。
