Exploring the Use of Neurofeedback by Cancer Survivors: Results of Interviews with Neurofeedback Providers and Clients

Evaluating the effectiveness of neurofeedback in chronic pain management: a narrative review

The prevalence and impact of chronic pain in individuals worldwide necessitate effective management strategies. This narrative review specifically aims to assess the effectiveness of neurofeedback, an emerging non-pharmacological intervention, on the management of chronic pain. The methodology adopted for this review involves a meticulous search across various scientific databases. The search was designed to capture a broad range of studies related to neurofeedback and chronic pain management. To ensure the quality and relevance of the included studies, strict inclusion and exclusion criteria were applied. These criteria focused on the study design, population, intervention type, and reported outcomes. The review synthesizes the findings from a diverse array of studies, including randomized controlled trials, observational studies, and case reports. Key aspects evaluated include the types of neurofeedback used (such as EEG biofeedback), the various chronic pain conditions addressed (like fibromyalgia, neuropathic pain, and migraines), and the methodologies employed in these studies. The review highlights the underlying mechanisms by which neurofeedback may influence pain perception and management, exploring theories related to neural plasticity, pain modulation, and psychological factors. The results of the review reveal a positive correlation between neurofeedback interventions and improved pain management. Several studies report significant reductions on pain intensity, improved quality of life, and decreased reliance on medication following neurofeedback therapy. The review also notes variations in the effectiveness of different neurofeedback protocols and individual responses to treatment. Despite the promising results, the conclusion of the review emphasizes the need for further research. It calls for larger, well-designed clinical trials to validate the findings, to understand the long-term implications of neurofeedback therapy, and to optimize treatment protocols for individual patients.

Exploring expectations of neurofeedback treatment among trauma-affected refugees

BACKGROUND

The use of Neurofeedback (NF) to assist individuals in learning to regulate their brain wave activity has shown promising results in reducing symptoms of posttraumatic stress disorder (PSTD). However, few studies have focused on the patients' understandings of NF and even fewer explore the perspective of refugees.

PURPOSE

To evaluate NF treatment for trauma-affected refugees by focusing on their expectations and understanding of NF.

METHODS

This qualitative study was a part of a mixed method study carried out at an outpatient mental health centre in Denmark, offering 34 trauma-affected refugees 12 sessions of NF. In this qualitative study, a subsample of seven participants was interviewed. Using in-depth semi-structured interviews, the participants' thoughts and expectations prior to participating in NF treatment were examined. The analysis was carried out in four steps, using a hermeneutic and phenomenological approach.

RESULTS

The analysis resulted in two themes: (1) Rationale and working mechanisms of NF and (2) Motivators for participating in the study.

CONCLUSION

The findings show that NF treatment for trauma affected refugees was challenged by difficulties in communicating the message about the NF equipment capabilities as well as the expected treatment outcome. These challenges included e.g. health professionals' ability to explain and the participants' cultural frame of reference. This is consistent with previous research, showing that compared to the native population, the dissemination of health information to refugees is more difficult and comprehensive. Further studies on how to ensure mutual understanding of the content of NF and expected treatment outcome are needed.

Sleep Disturbances and Their Association With Quality of Life in Older Psychiatric Patients During the COVID-19 Pandemic

AIMS

The negative effect of the COVID-19 pandemic on sleep quality of clinically stable psychiatric patients is unknown. This study examined the prevalence of sleep disturbances and their association with quality of life (QOL) in clinically stable older psychiatric patients during the COVID-19 pandemic.

METHODS

This multicenter, cross-sectional study involved older patients attending maintenance treatment at outpatient departments of four major psychiatric hospitals in China. Patients' socio-demographic and clinical characteristics were collected. Sleep disturbances, depressive symptoms, and QOL were assessed with the Insomnia Severity Index, the 9-item Patient Health Questionnaire, and 2 items of the World Health Organization Quality of Life-Brief version, respectively. Binary logistic regression analysis was conducted to examine the independent associations of socio-demographic and clinical variables with sleep disturbances, while the association between sleep disturbances and QOL was explored with analysis of covariance.

RESULTS

A total of 941 patients were recruited. The prevalence of sleep disturbances was 57.1% (95% CI: 53.9-60.2%). Analysis of covariance revealed that QOL was significantly lower in patients with sleep disturbances compared to those without. Multivariate logistic regression analysis showed that sleep disturbances were positively and independently associated with more severe depressive symptoms (OR = 1.32, 95% CI: 1.26-1.37). Compared to patients with major depressive disorder, those with other psychiatric diagnoses had a significantly higher prevalence of sleep disturbances (OR = 1.44, 95% CI: 1.00-2.08).

CONCLUSION

Sleep disturbances were common among clinically stable older psychiatric patients during the COVID-19 pandemic. Considering the negative association with QOL, this subpopulation needs regular assessment and timely treatment to reduce their sleep disturbances and improve their QOL.

The effects of neurofeedback training on short-term memory and quality of life in women with breast cancer

Background/Aims

Breast cancer, one of the most common cancers among Iranian women, affects the physical, psychological and cognitive dimensions of patients' lives. The aim of the present study was to investigate the effects of neurofeedback training on short-term memory and quality of life in patients with breast cancer.

Methods

In a randomised, controlled pilot trial, a convenient sample of 20 Iranian women with breast cancer who had received chemotherapy and radiotherapy were randomly allocated to an intervention or control group. The intervention group received 4 weeks of neurofeedback training. Assessment tools in pre- and post-test sessions included the Wechsler short-term memory scale and SF-36 quality of life questionnaire. Data were analysed by a biostatistician blinded to the study.

Results

Short-term memory and quality of life scores improved significantly in the intervention group after neurofeedback training compared to the control group (P=0.001).

Conclusions

Findings indicate that neurofeedback training is an effective technique for improving short-term memory and quality of life alongside occupational therapy interventions in women after breast cancer treatment.
