Brain Training for Substance Use Disorders

The main purpose of this project is to gather pilot data on neurofeedback games that use electroencephalogram (EEG)-based Attention Bias Modification (ABM) to reduce cue-induced drug craving processes in individuals with Opioid Use Disorder (OUD). The project will involve the use of three empirically-supported and potentially therapeutic games that include drug- (such as pill bottle and syringe) and non-drug-related stimuli (such as food and smiling faces). An EEG system will be used to monitor brain activity during gameplay.

The neurofeedback loop for attention training will be synchronized to cue presentations using EEGs which monitor visual Event-Related Potentials (ERP) signatures of attention. The degree of difficulty (i.e., cue content) on subsequent trials of the game will be determined based on the level of attention measured in the neurofeedback loop.

Inclusion criteria

• DSM-IV-TR diagnosis of OUD;
• Ability to provide informed consent;
• A minimum of a 6th grade reading level; and
• Able and willing to provide own contact information for follow-up visit(s).

Control participants:

• Age- and gender-matched to an OUD patient participant in the study;
• Ability to provide informed consent;
• A minimum of a 6th grade reading level;
• Able and willing to provide own contact information for follow-up visit(s).

Exclusion criteria

OUD patient participants:
