Abstract

Objetive

The main aim of this study is to characterize the profile of emotional functioning (emotion recognition and experience and interoception) and neuropsychological performance (frontal-executive related behavioural dysfunction, flexibility and decision-making) in polysubstance users vs. controls.

Material and method

The sample is composed by 60 subjects: 30 polysubstance abusers currently in treatment and 30 healthy individuals that formed the control group. Questionnaire measures were used to assess interoception and alexythimia, and performance tests were used for assessment of emotion recognition and experience and executive functions.

Results

Polysubstance abusers showed increased levels of alexithymia and somatosensory amplification, poorer recognition of fear, sadness and disgust, and a flattened arousal response towards natural reinforcing stimuli. With regard to neuropsychological performance, polysubstance abusers had poorer switching and greater behavioural problems related to frontal striatal systems than the control group. We found significant correlations between alexithymia and somatosensory amplification, both dimensions correlated with executive dysfunctions, and between decision making and perception of fear.

Conclusions

Polysubstance abusers have combined interrelated deficits in neurocognitive and emotional functions.

多药使用者在治疗中的情绪处理、间感觉和执行功能

目的本研究的主要目的是表征多物质使用者与对照组的情绪功能(情绪识别和体验和内感受)和神经心理表现(额叶执行相关的行为功能障碍，灵活性和决策)的特征。材料与方法样本由60名受试者组成:30名正在接受治疗的多种药物滥用者和30名健康个体组成对照组。问卷测量法用于评估内感受和述情障碍，表现测试法用于评估情绪识别和体验以及执行功能。结果多药物滥用者述情障碍和躯体感觉放大水平增加，对恐惧、悲伤和厌恶的识别能力下降，对自然强化刺激的唤醒反应变平。在神经心理表现方面，与对照组相比，多药物滥用者的转换能力较差，与额纹状体系统相关的行为问题更大。我们发现述情障碍和躯体感觉放大之间存在显著相关性，这两个维度都与执行功能障碍相关，决策和恐惧感知之间也存在显著相关性。结论多种药物滥用者存在神经认知和情绪功能的相关缺陷。
