Abstract: (23 Views)
Background: Technology-based interventions such as electrical brain stimulation may be effective in the craving and absolute power of the alpha wave of substance abusers, including nicotine dependents.
Aims: We conducted this study to investigate the effectiveness of transcranial alternating current stimulation (tACS) using alpha frequency on craving and absolute power of the alpha wave in nicotine-dependent individuals.
Methods: We used a pre-test/post-test quasi-experimental design with control and sham groups. We selected 30 eligible nicotine addicts from Mashhad city in the spring of 2022 using the available sampling method and randomly divided the subjects into three groups. We applied the intervention in 8 sessions for 20 minutes in the dorsolateral prefrontal cortex for the first group, sham interventions for the second group, and no intervention for the third group. We collected experimental data with the Fagerström Questionnaire (FTQ,1991), Quantitative Electroencephalogram (QEEG) and the craving use drugs questionnaire (Franken,2008). After eight sessions, we evaluated those people's craving and absolute power of the alpha wave and analyzed the results using multiple covariance analysis. The data was analyzed by multivariate analysis of variance and by SPSS 19 software.
Results: The effectiveness of Alpha-tACS intervention on short-term craving and absolute power of the alpha wave was significantly different in the experimental group compared to other groups (P= 0.001).
Conclusion: Alpha-tACS intervention effectively reduce craving,increase absolute power of the alpha wave in nicotine-dependent individuals.
