Methods: Forty-six AD patients aged 49 - 76 years were recruited for the study. Neurofeedback regulation was conducted using a BCI game designed to modulate EEG rhythms. Cognitive function was assessed using MMSE, MoCA, and ADAS-cog scales before and after a 10-day training period. EEG measurements were taken to evaluate changes in brain activity complexity. Statistical analyses were performed using SPSS25.0 software to compare pre- and post-training scores. Results: Post-intervention results showed significant improvement in the cognitive function of AD patients. The total scores of MMSE, MoCA, and ADAS-cog scales increased significantly (P < 0.01). Notable improvements were observed in memory, language, and attention domains. EEG complexity in the left frontal area also showed a significant increase (P < 0.05). Additionally, the disruptive behaviors of patients were significantly reduced, improving their overall quality of life. Conclusions: Neurofeedback therapy based on BCI games is a promising intervention for enhancing cognitive functions and reducing disruptive behaviors in AD patients. This innovative approach demonstrates significant potential for clinical application, providing a non-invasive method to improve patient outcomes. Further studies with larger sample sizes and long-term follow-ups are recommended to validate these findings and explore the specific effects of NFB training on different cognitive impairment levels.展开更多

The clinical alterations associated with these pathologies are multiple and have a complex psycho-organic character that moves along the micorobiome-gut-brain-axis. For the present study, 45 patients of both sexes (19 male, 26 female) aged 30 - 59 years were enrolled because of a diagnosis of Functional pain syndromes (FPS) that lasted for more than 6 months. All patients underwent pre-treatment clinical assessments (T0) for anxiety disorder, multidimensional assessment of pain, monitoring of baseline values of Alpha-Theta cerebral rhythm in occipital region and monitoring of salivary cortisol levels. All the patients underwent a clinical treatment combined with central neuromodulation with neurofeedback—Alpha Theta increase protocols (once a week for three months), administration of multispecies probiotic (one dose per day for 3 months) and clinical psychological interviews (once a week for three months). At the end of treatment (T1), patients were re-evaluated. Results show statistically relevant improvements of each feature considered: the Relief from Pain provided by the medication increases on average from 36.6% to 87.3%, the salivary Cortisol level at 11 pm decreases from 6.4 ng/ml to a physiological value of 1.2 ng/ml, and the anxiety rating score is reduced from 28 to 12. Moreover, the 23.9% increase in α-θ relative power shows the positive outcome of the brain autoregulation. This study highlights that the combined approach of Neurofeedback with drugs and multispecies probiotic results in great improvements in the patients’ life.展开更多

Although many previous studies have demonstrated that neurofeedback training alters the functional connectivity between brain regions in the task state and resting state, it is unclear how the regulation of the key hub of the default mode network (DMN) affects the topological properties of the resting-state brain network. The current study aimed to investigate what topological changes would occur in the large-scale intrinsic organization of the resting state after the real-time down-regulation of the posterior cingulate cortex (PCC). The results indicated that the down-regulation of the PCC in the DMN reduced the functional connectivity of the PCC with the nodes outside of the DMN and reduced functional connectivity between the superior medial frontal gyrus (SFGmed) and parahippocampal gyrus (PHG) in the experimental group. Moreover, the nodal graph properties of the SFGmed were reduced, while that of the PHG showed the opposite alteration after the down-regulation of the PCC. These findings possibly suggest that the regulation of the key hub of the DMN, the PCC, mainly changed the information transfer of the SFGmed and PHG.展开更多

Information about visual-spatial attention mainly arises from studies using event-related potentials (ERPs) during Posner’s spatial cueing paradigm. This study aims to use neurofeedback with a special protocol for treating children with reading disabilities, and moreo-ver, to evaluate visual-spatial attention ability by means of Posner paradigm task and ERPs. The study was conducted in a single subject design in 20 sessions. Participants were 2 male children, aged between 10 - 12 years old, who completed twelve 30-min neurofeedback sessions. Repeated measurements were performed during the baseline, treatment, and post treatment phases. Results showed some improvement in Posner paradigm parameters (correct response, valid and invalid reaction times). Furthermore, grand average ERPs for both of the participants in each of the four conditions (Valid-right, Invalid-right, Valid-left and Invalid-left) were analyzed. The analysis of P3 component showed a reduction in latency, indicating an improvement in the timing of cognitive processes. In addition, the graphs showed a decrease in amplitude level, which meant easier processing than before.展开更多

However, randomized controlled clinical trials are still needed for evaluation of this treatment as a standard option. This preliminary study was aimed to evaluate the effect of NET on continuous attention （CA） and short-term memory （STM） of clients with moderate TBI using a randomized controlled clinical trial （RCT）. Methods： In this preliminary RCT, seventeen eligible patients with moderate TBl were randomly allo- cated in two intervention and control groups. All the patients were evaluated for CA and STM using the visual continuous attention test and Wechsler memory scale-4th edition （WMS-IV） test, respectively, both at the time of inclusion to the project and four weeks later. The intervention group participated in 20 sessions of NFT through the first four weeks. Conversely, the control group participated in the same NF sessions from the fifth week to eighth week of the project. Results： Eight subjects in the intervention group and five subjects in the control group completed the study. The mean and standard deviation of participants＇ age were （26.75 ~ 15.16） years and （2Z60 ＋_ 8.17） years in experiment and control groups, respectively. All of the subjects were male. No significant improvement was observed in any variables of the visual continuous attention test and WMS-IV test between two groups （p _~ 0.05）. Conclusion： Based on our literature review, it seems that our study is the only study performed on the effect of NET on TBl patients with control group. NET has no effect on CA and STM in patients with moderate TBI. More RCTs with large sample sizes, more sessions of treatment, longer time of follow-up and different orotocols are recommended.展开更多
