Aims The current study examined the association between pain catastrophizing and alcohol cue-elicited brain activation in individuals with alcohol use disorder (AUD). Methods Non-treatment seeking heavy drinkers with AUD (n = 45; 28 males) completed self-report measures of pain catastrophizing and alcohol use/problems as part of a clinical trial of the neuroimmune modulator ibudilast. Participants were randomized to either placebo (n = 25) or ibudilast (n = 20) and completed an functional magnetic resonance imaging (fMRI) scan to assess neural activation to alcohol cues 1 week into the medication trial. Multiple linear regression examined whether pain catastrophizing predicted cue-induced activation in a priori regions of interest, namely the dorsal and ventral striatum (VS). An exploratory whole-brain analysis was conducted to assess the relationship between pain catastrophizing and neural alcohol cue reactivity. Results Pain catastrophizing predicted greater cue-induced activation in the dorsal (b = 0.006; P = 0.03) but not VS controlling for medication. Pain catastrophizing was positively associated with neural activation to alcohol cues in regions including the bilateral thalamus, left precuneus and left frontal pole. Conclusion Greater pain catastrophizing is associated with greater cue-induced neural activation in brain regions sub-serving habits and compulsive alcohol use. These findings provide initial support for a neural mechanism by which pain catastrophizing may drive alcohol craving among individuals with AUD.

酒精使用障碍患者的疼痛灾难化与酒精提示引起的神经活动增加有关

目的 当前的研究调查了酒精使用障碍 (AUD) 患者的疼痛灾难化与酒精提示引发的大脑激活之间的关联。方法 未接受治疗的 AUD 重度饮酒者(n = 45;28 名男性)完成了疼痛灾难性和饮酒/问题的自我报告测量,作为神经免疫调节剂异丁司特临床试验的一部分。参与者被随机分配到安慰剂 (n = 25) 或异丁司特 (n = 20) 组,并在药物试验 1 周后完成功能性磁共振成像 (fMRI) 扫描,以评估酒精线索的神经激活情况。多元线性回归检查了疼痛灾难化是否预测了先验感兴趣区域(即背侧和腹侧纹状体(VS))中线索诱导的激活。进行了探索性全脑分析,以评估疼痛灾难化和神经酒精提示反应之间的关系。结果 疼痛灾难化预测了背侧更大的提示诱导激活(b = 0.006;P = 0.03),但不是 VS 控制药物治疗。疼痛灾难化与双侧丘脑、左侧楔前叶和左侧额极等区域的酒精信号神经激活呈正相关。结论 更大的疼痛灾难化与遵循习惯和强迫性饮酒的大脑区域中更大的提示诱导神经激活有关。这些发现为神经机制提供了初步支持,通过这种机制,疼痛灾难性可能会导致 AUD 患者对酒精的渴望。结果 疼痛灾难化预测了背侧更大的提示诱导激活(b = 0.006;P = 0.03),但不是 VS 控制药物治疗。疼痛灾难化与双侧丘脑、左侧楔前叶和左侧额极等区域的酒精信号神经激活呈正相关。结论 更大的疼痛灾难化与遵循习惯和强迫性饮酒的大脑区域中更大的提示诱导神经激活有关。这些发现为神经机制提供了初步支持,通过这种机制,疼痛灾难性可能会导致 AUD 患者对酒精的渴望。结果 疼痛灾难化预测了背侧更大的提示诱导激活(b = 0.006;P = 0.03),但不是 VS 控制药物治疗。疼痛灾难化与双侧丘脑、左侧楔前叶和左侧额极等区域的酒精信号神经激活呈正相关。结论 更大的疼痛灾难化与遵循习惯和强迫性饮酒的大脑区域中更大的提示诱导神经激活有关。这些发现为神经机制提供了初步支持,通过这种机制,疼痛灾难性可能会导致 AUD 患者对酒精的渴望。疼痛灾难化与双侧丘脑、左侧楔前叶和左侧额极等区域的酒精信号神经激活呈正相关。结论 更大的疼痛灾难化与遵循习惯和强迫性饮酒的大脑区域中更大的提示诱导神经激活有关。这些发现为神经机制提供了初步支持,通过这种机制,疼痛灾难性可能会导致 AUD 患者对酒精的渴望。疼痛灾难化与双侧丘脑、左侧楔前叶和左侧额极等区域的酒精信号神经激活呈正相关。结论 更大的疼痛灾难化与遵循习惯和强迫性饮酒的大脑区域中更大的提示诱导神经激活有关。这些发现为神经机制提供了初步支持,通过这种机制,疼痛灾难性可能会导致 AUD 患者对酒精的渴望。
