“…In relation to the study design, four studies were randomised clinical trials with two groups, experimental and control; one was a case study [43]; and three studies were non-randomised clinical trials [38][39][40]. Among the clinical trial studies, two included an experimental and a control group, in which the latter was maintained on treatment as usual (TAU) procedures [41,42]; one study with an AUD experimental group, an AUD control group kept in TAU and a no-AUD control who underwent neurofeedback sessions [15]; and another one included a non-equivalent pretest-posttest control group, in which participants were randomised in disproportionate groups of individuals, divided in experimental and control on TAU [20].…”

“…However, Ko and Park [20] investigated the reduction of brain hyperexcitation by inhibiting high‐frequency beta waves, which are usually excessive in people who abuse alcohol, and increasing the alpha frequency, using the alpha‐beta protocol. They found promising results, opening the question about the specificity of the alpha‐theta protocol or, also, if the main effect of neurofeedback in this population is the modulation of alpha, regardless of whether the reinforcement is given for the alpha/beta or alpha/theta ratio.…”

Issues Alcohol use disorder (AUD) causes the highest harms around the world. Many people use alcohol to reduce stress and anxiety, considered as risk factors for AUD. Chronic alcohol use leads to changes in the reward system and the high level of stress may exacerbate neuroendocrine responses. Electroencephalographic (EEG) neurofeedback shows reduction of stress, anxiety and alcohol abuse and it could be an important tool for reducing harm and risk associated with AUD. The aim of this paper is to review the studies that investigated the effects of EEG neurofeedback in subjects with AUD and it proposes to discuss this intervention as a tool for reducing harm and risk in AUD. Approach Medline, PsycINFO and LILACS databases were searched and appropriated terms were used. Inclusion criterion was adopted. The year of publication was not limited because of the scarce number of studies. Eighty‐two papers returned and eight were included. A critical review was conducted. Key Findings Most of the papers analysed used the alpha/theta protocol to reduce the ‘hyperexcitation’ of the nervous system. This protocol provides relaxation, decreases anxiety or stress, prevents alcohol relapse, maintains abstinence and increases the feeling of well‐being. Implications EEG neurofeedback has important effects on AUD and anxiety or stress. Studies reinforce the use of EEG neurofeedback as an alternative tool for reducing harm and risk in AUD. Conclusion EEG neurofeedback is an intervention to treat AUD, specifically, to reduce harm and risk. However, more randomised studies are necessary to consolidate the effectiveness of the technique.

“…The gamma/γ powers, but not other frequency bands, were elevated across the cortex of patients with AUD (Bauer, 2001). However, Ko and Park showed that there was a reduction in alpha/α power while an increase in gamma/γ powers (Ko & Park, 2018). Interestingly, by analyzing EEG obtained from 191 male alcoholic patients, Coutin-Churchman et al revealed that the most frequent reduction took place in the delta/δ and theta/θ bands (Coutin-Churchman et al, 2006).…”

Electroencephalography (EEG) likely reflects activity of cortical neurocircuits, making it an insightful estimation for mental health in patients with substance use disorder (SUD). EEG signals are recorded as sinusoidal waves, containing spectral amplitudes across several frequency bands with high spatio-temporal resolution. Prior work on EEG signal analysis has been made mainly at individual electrodes. These signals can be evaluated from advanced aspects, including sub-regional and hemispheric analyses. Due to limitation of computational techniques, few studies in earlier work could conduct data analyses from these aspects. Therefore, EEG in patients with SUD is not fully understood. In the present retrospective study, spectral powers from a data house containing opioid (OUD), methamphetamine/stimulants (MUD), and alcohol use disorder (AUD) were extracted, and then converted into five distinct topographic data (i.e., electrode-based, cortical subregion-based, left-right hemispheric, anterior-posterior based, and total cortex-based analyses). We found that EEG spectral powers in patients with OUD were significantly different from those with MUD or AUD. Differential changes were observed from multiple perspectives, including individual electrodes, subregions, hemispheres, anterior-posterior cortices, and across the cortex as a whole. Understanding the differential changes in EEG signals may be useful for future work with machine learning and artificial intelligence (AI), not only for diagnostic but also for prognostic purposes in patients with SUD.

“…As the brain's executive center is responsible for advanced thinking skills, the prefrontal cortex forms personality, regulates the depth of emotions (such as anger and aggression) and controls logical thinking. QEEG has a long history and its clinical usefulness has gradually become well-known [17][18][19][20]. The rapid development of desktop computers in the 1990s placed QEEG technology in the hands of clinicians.…”

We examined the association between multidimensional empathy, brain function, and mental fitness and identified correlates of mental fitness. In total, 146 female high school freshmen from a South Korean school participated in this cross-sectional study. Data were collected from March to April 2019, using a self-report questionnaire and quantitative electro-encephalographic data (QEEG). Instruments included the Interpersonal Reactivity Index and the Mental Fitness Scale, to access multidimensional empathy and mental fitness. Prefrontal cortex brain function was assessed with the brain quotient measure from the QEEG during free time after school. Data were analyzed using descriptive statistics, Pearson’s correlation coefficient, and multiple regression analysis. Mental fitness had statistically significant relationships with multidimensional empathy (r = 0.36, p < 0.001) and brain quotient (r = 0.23, p = 0.005). Demographic factors affecting mental fitness included satisfaction with school life (β = 0.23, p = 0.001) and economic status (β = 0.17, p = 0.024). Factors from the subscales of multidimensional empathy included perspective taking (β = 0.26, p = 0.001), fantasy (β = 0.22, p = 0.004), and personal distress (β = −0.19, p = 0.010); and the brain function factor was brain quotient (β = 0.14, p = 0.038). The explanatory power of the model was 49.4% (F = 14.44, p < 0.001). There is a need for a concrete and objective understanding of mental fitness in adolescents to develop intervention programs for freshmen with various maladaptation problems.

Effects of Quantitative Electroencephalography Based Neurofeedback Training on Autonomous Regulations in Patients with Alcohol Use Disorder

Abstract: Neurofeedback training is recommended for improving autonomous regulation in alcohol use disorder as a nursing intervention. However, for significantly attenuating hyperarousal through brain wave correction, it may be necessary to increase the number of neurofeedback sessions.
