“…The sampling frequency was 512 Hz. Parameters used in this study such as the number of sessions, the duration of the training and the choice of the tasks were designed following some previous works methods (Marzbani et al, 2016;Arns et al, 2017;Enriquez-Geppert et al, 2017), current guidelines (Dessy et al, 2020;Ros et al, 2020;Steingrimsson et al, 2020) and experts recommendations for EEG NF training implementation (Micoulaud-Franchi et al, 2015;Zivoder et al, 2015;Banerjee and Argaez, 2017). The NF training was carried out for 20 sessions, twice a week for 10 weeks.…”

“…This last decade, knowledge regarding principles and technical aspects to achieve the efficient use of EEG NF improved a lot (Marzbani et al, 2016;Arns et al, 2017;Enriquez-Geppert et al, 2017). Among the NF protocols, the NF sensorimotor (SMR NF) appears to be one of the most effective (Dessy et al, 2020). It is based on brain oscillations of 12-15 Hz frequency training, recorded over central scalp regions, and generated in a reticular-thalamocortical network (Sterman, 1996(Sterman, , 2000.…”

Background: Neurofeedback (NF) training, as a method of self-regulation of brain activity, may be beneficial in elderly patients with mild cognitive impairment (MCI). In this pilot study, we investigated whether a sensorimotor (SMR)/theta NF training could improve cognitive performance and brain electrical activity in elderly patients with MCI. Methods: Twenty elderly patients with MCI were assigned to 20 consecutive sessions of sensorimotor (SMR)/theta NF training, during 10 weeks, on a basis of two sessions each week. Neuropsychological assessments and questionnaires, as well as electroencephalogram (EEG), were performed and compared between baseline (T0), after the last NF training session at 10 weeks (T1), and 1-month follow-up (T2). Results: Repeated measures ANOVA revealed that from baseline to post-intervention, participants showed significant improvement in the Montreal cognitive assessment (MoCa, F = 4.78; p = 0.012), the delayed recall of the Rey auditory verbal learning test (RAVLT, F = 3.675; p = 0.032), the Forward digit span (F = 13.82; p < 0.0001), the Anxiety Goldberg Scale (F = 4.54; p = 0.015), the Wechsler Adult Intelligence Score-Fourth Edition (WAIS-IV; F = 24.75; p < 0.0001), and the Mac Nair score (F = 4.47; p = 0.016). EEG theta power (F = 4.44; p = 0.016) and alpha power (F = 3.84; p = 0.027) during eyes-closed resting-state significantly increased after the NF training and showed sustained improvement at a 1-month follow-up.

“…As we hypothesized, the changes produced by the NFB treatment in the theta and beta frequency bands not only persisted but were also enhanced one year later. It has been proposed that the changes produced by NFB comprise a reorganization of the overall EEG activity and do not merely imply local changes associated with the target electrode and training frequency [ 30, 69, 70 ].…”

“…Neurofeedback (NFB) is a neuroregulatory training tool that aims to modify specific characteristics of brain activity through the application of operant conditioning. In the particular case of EEG-based NFB, individuals can learn to modify their brain’s electrical activity [ 30, 31 ]. This training has been used in older adults, both healthy and with NCD, to improve certain aspects of their cognitive performance.…”

Background: In healthy older adults, excess theta activity is an electroencephalographic (EEG) predictor of cognitive impairment. In a previous study, neurofeedback (NFB) treatment reinforcing reductions theta activity resulted in EEG reorganization and cognitive improvement. Objective: To explore the clinical applicability of this NFB treatment, the present study performed a 1-year follow-up to determine its lasting effects. Methods: Twenty seniors with excessive theta activity in their EEG were randomly assigned to the experimental or control group. The experimental group received an auditory reward when the theta absolute power (AP) was reduced. The control group received the reward randomly. Results: Both groups showed a significant decrease in theta activity at the training electrode. However, the EEG results showed that only the experimental group underwent global changes after treatment. These changes consisted of delta and theta decreases and beta increases. Although no changes were found in any group during the period between the posttreatment evaluation and follow-up, more pronounced theta decreases and beta increases were observed in the experimental group when the follow-up and pretreatment measures were compared. Executive functions showed a tendency to improve two months after treatment which became significant one year later. Conclusion: These results suggest that the EEG and behavioral benefits of this NFB treatment persist for at least one year, which adds up to the available evidence contributing to identifying factors that increase its efficacy level. The relevance of this study lies in its prophylactic features of addressing a clinically healthy population with EEG risk of cognitive decline.

“…In both mental and physical training, digital health, wearables, and remote monitoring are likely to play important roles in study design as well as in developing individualized patient “prescriptions,” and for monitoring progress and efficacy of treatment. Along these lines, considerable attention and research activities have focused on virtual reality, high-density electroencephalogram neurofeedback and other methods to reduce MS. 209 These tools offer objective measures of neural activity that can be observed in real-time during stress management activities and could provide the basis for goal-directed training and tracking longitudinal progress over time.…”
