Abstract:

Drug addicts have decision-making defects, and show the characteristics of impulsivity, risk-taking, dysfunctional reward processing, and lack of signals in bodies. Neuroimaging studies have shown that abuse of addictive drugs may cause damage to some brain areas such as DLPFC, ACC, OFC, VMPFC, Amygdala, Insula, etc, that may be incur addicts' decision-making defects. Cognitive training is beneficial to improve individuals' decision-making ability, for instance, goal management training and mindfulness meditation can improve working memory, promote self-awareness and goal oriented behavior; while, noninvasive brain stimulation can directly change the active state of addicts' brain regions that related to decision-making, hence, the cognitive function related to decision-making is improved. All in all, in the future cognitive training and noninvasive brain stimulation still have a broad space to expand in the aspect of addiction intervention.

Key words: drug addiction, decision-making defects, addiction intervention, impulsivity, risk-taking, dysfunctional reward processing
