Deficiencies and prospects
alcohol-dependent, AD
However, there are some deficiencies in this study. First, the sample size of this study is small, and the study subjects are all male AD patients, resulting in the effect of VR cues exposed to induce and treat alcohol craving being gender different and not universal. Second, this study did not design a traditional CET as a control group, and it is impossible to compare whether the VR-CET is better than the traditional CET. Finally, the intervention duration and intervention period of this study were short, and long-term follow-up was not conducted to understand the long-term effectiveness of VR-CET.Future studies are still needed to further verify the relationship between heart rate, skin conductance, and respiration and craving. Future studies could also add aversion therapy or relaxation therapy after CET to increase the efficacy of the treatment. In addition, it is possible to monitor the patient’s blood pressure changes and use eye-tracking technology to track the participants’ gaze objects, gaze duration and other information to explore objective physiological indicators that can effectively reflect craving and help in the assessment and treatment of alcohol-dependent patients.
