简要总结
This study will examine the impact of functional near-infrared spectroscopy-based neurofeedback to a region within the brain's prefrontal cortex involved with self-regulation of resisting craving in alcohol use and prescription opioid use disorder patients. Participants will be asked to complete two cue reactivity tasks, six sessions of neurofeedback training as well as craving visual analog scales and self-efficacy questionnaires throughout a two-week period of their time in residential treatment at the Caron Treatment Center. They will be followed for 90 days after treatment completion at Caron to assess the impact neurofeedback had on their ability to remain sober once patients are living back in the "real world".

研究组 & 干预措施
Experimental Group for AUD Patients
Patients will undergo six NFB sessions from the rDLPFC using a closed-loop fNIRs-based system. During each session, participants will walk through a maze on a computer screen three times. Each maze consists of alternating 30-second rest and 30-second active blocks. During each active block, the participant will come into visual contact with an alcohol image, blocking them from progressing through the maze. When patients encounter the alcohol image and they increase activity in their rDLPFC, the image in the maze will decrease in size and vice versa. The size of the alcohol image can fluctuate throughout each thirty second active block as the raw fNIRs signal from the rDLPFC will be sampled every 500 milliseconds using COBI studio software.
干预措施: fNIRs-based Neurofeedback (Device)
Sham Feedback Group for AUD Patients
Patients will undergo six sham feedback sessions from the skin over the zygomatic arch using a closed-loop fNIRs-based system. During each session, participants will walk through a maze on a computer screen three times. Each maze consists of alternating 30-second rest and 30-second active blocks. During each active block, the participant will come into visual contact with an alcohol image, blocking them from progressing through the maze. When participants encounter the alcohol image and they increase blood supply over the zygomatic area, the image will decrease in size and vice versa. The size of the alcohol image can fluctuate throughout each thirty second active block as the raw fNIRs signal from the zygomatic area will be sampled every 500 milliseconds using COBI studio software.

Experimental Group for pOUD Patients
Patients will undergo six NFB sessions from the rDLPFC using a closed-loop fNIRs-based system. During each session, participants will walk through a maze on a computer screen three times. Each maze consists of alternating 30-second rest and 30-second active blocks. During each active block, the participant will come into visual contact with a pill image, blocking them from progressing through the maze. When patients encounter the pill image and they increase activity in their rDLPFC, the image in the maze will decrease in size and vice versa. The size of the pill image can fluctuate throughout each thirty second active block as the raw fNIRs signal from the rDLPFC will be sampled every 500 milliseconds using COBI studio software.

结局指标
主要结局
Improved capacity to increase neural activity in response to alcohol/pill cues in the rDLPFC measured by the change in the blood-oxygen level dependent (BOLD) signal
时间窗: First two weeks of protocol
Increase in fNIRs signal response to pill/alcohol cues from pre-to-post neurofeedback sessions.
时间窗: First two weeks of protocol
Increase in neural activation in the rDLPFC when viewing alcohol cues from the first neurofeedback session to the sixth (last) session.
Higher levels of abstinence 90-days post-residential treatment completion as assessed by the 7-day timeline followback questionnaires.
时间窗: First 90 days after treatment completion at Caron Treatment Center
7-day timeline followback questionnaire will be sent out every week for 12 weeks to assess abstinence
次要结局
- Change in self-reported self-efficacy from pre-to-post neurofeedback sessions assessed via the brief situational confidence questionnaire.(First two weeks of protocol)
- Change in self-reported craving from pre-to-post neurofeedback sessions assessed via a 100-point craving visual analog scale.(First two weeks of protocol)
