“…NFT led to greater consistency in response times on a response inhibition task for subjects scoring in healthy or abnormal ADHD ranges, agreeing with similar reports of subjects with ADHD [ 79 , 80 ]. In addition, the RCI demonstrated that approximately 50% of healthy participants improved their average response time, while similarly, participants in abnormal ranges reduced omission errors.…”

Background Neurofeedback training (NFT) has been shown to be effective in treating several disorders (eg, attention-deficit/hyperactivity disorder [ADHD], anxiety, and depression); however, little is currently known regarding the effectiveness of remote NFT systems. Objective This retrospective study provides real-world data (N=593) to assess the efficacy of app-based remote NFT in improving brain health and cognitive performance. Methods Improvement was measured from pre- to postintervention of in-app assessments that included validated symptom questionnaires (the 12-item General Health Questionnaire, the ADHD Rating Scale IV, the Adult ADHD Self-Report Scale, the 7-item Generalized Anxiety Disorder scale, and the 9-item Patient Health Questionnaire), a cognitive test of attention and executive functioning (ie, continuous performance task), and resting electroencephalography (EEG) markers. Clinically significant improvement was evaluated using standard approaches. Results The greatest improvement was reported for the anxiety questionnaire, for which 69% (68/99) of participants moved from abnormal to healthy score ranges. Overall, adult and child participants who engaged in neurofeedback to improve attention and executive functions demonstrated improved ADHD scores and enhanced performance on a cognitive (ie, response inhibition) task. Adults with ADHD additionally demonstrated elevated delta/alpha and theta/alpha ratios at baseline and a reduction in the delta/alpha ratio indicator following neurofeedback. Conclusions Preliminary findings suggest the efficacy of app-based remote neurofeedback in improving mental health, given the reduced symptom severity from pre- to postassessment for general psychological health, ADHD, anxiety, and depression, as well as adjusted resting EEG neural markers for individuals with symptoms of ADHD. Collectively, this supports the utility of the in-app assessment in monitoring behavioral and neural indices of mental health.

Shift work is an inconsistent and atypical work schedule. This study aimed to investigate the influence of shift work on the Quality of Sleep (QOS) and Executive Functions (EF). Thirty shift workers and thirty day workers first completed a demographic questionnaire. They then were tested using the Pittsburgh Sleep Quality Index (PSQI) and EF tests, including the Corsi Block-Tapping Task (CBTT), Berg's Card Sorting Task (BCST), and the Continuous Performance Task (CPT). Results were subjected to non-parametric Chi-Square Tests, the Mann-Whitney U Test, and Independent T-Tests. Shift workers had significantly poorer sleep quality than day workers, which was shown in PSQI global scale (p = 0.001), sleep duration (p = 0.042), habitual sleep efficiency (p = 0.021), and sleep disturbance (p =0.021). Concerning EF tests, shift workers performed significantly poorer on CBTT (p = 0.019) and BCST (p =0.015, 0.047) compared with day workers. Significant differences were also observed between shift workers and day workers in terms of variables of omission errors (p = 0.037) and commission errors (p = 0.041) on CPT, but no significant difference was found between shift workers and day workers in reaction time (p = 0.561). Shift work impaired EF. These findings are related to shift workers' poorer sleep and its detrimental effects on areas of the brain, which are critical for EF, such as the prefrontal area. Our results suggest the evaluation and implication of practices and policies to assuage the consequences of working in shifts.

“…This figure describes the process of evaluating the literature and eliminating studies which do not fit the inclusion criteria in this review. Nine publications were selected into the systematic review (Dentz et al, 2020; Gropper, 2014; Jaquerod et al, 2020; Mawjee et al, 2015, 2017; Ryoo & Son, 2015; Stern et al, 2016; Virta et al, 2010; Zilverstand et al, 2017).

“…The authors state that a benefit of this program is that the participant can choose the time of the training to fit their schedule. The third included study on 16 university students with ADHD used a continuous performance task described as similar to a go/no-go paradigm as an outcome measure (Ryoo & Son, 2015). A Korean CCT task where participants practice a game of archery and racing was used.…”

Objective: Treatments for adults with attention-deficit hyperactivity disorder (ADHD) are understudied, compared to children and adolescents with the same condition. In this systematic review and random-effects meta-analysis, we aim to evaluate the outcomes of computerized cognitive training (CCT) interventions in randomized controlled trials (RCTs) including adults with ADHD. Method: Cognitive outcomes and ADHD symptom severity were analyzed separately. In addition, the Cattell–Horn–Carroll (CHC) theory of cognitive abilities was used to categorize outcome variables into subdomains, which were analyzed separately in a subsequent analysis. Results: The results revealed a small positive change in overall cognitive functioning, a measure of all cognitive outcomes in each study, for individuals who took part in CCT compared to controls (k = 9, Hedge’s g = 0.235, 95% CI [0.002, 0.467], p = 0.048, τ2 = 0.000, I2 = 0.000). However, neither symptom severity nor specific cognitive outcomes (executive functioning, cognitive speed, or working memory) showed a significant improvement. Conclusions: We analyzed the risk of bias in the chosen studies and discuss the findings in terms of effect size. It is concluded that CCT has a small positive effect in adults with ADHD. Due to the lack of heterogeneity in intervention designs across the included studies, increased heterogeneity in future studies could help inform clinicians about the aspects of CCT, such as training type and length, that are most beneficial for this group.
