Background. Mindfulness-based interventions (MBIs) have emerged as an alternative intervention for symptoms of psychological and psychiatric conditions, such depression, anxiety, emotional discomfort. Over the last ten years, MBIs established a growing body evidence that shows cognitive neurophysiological benefits. Depression anxiety are conditions with high prevalence in world population. In developing countries, it is reported that, given being at social disadvantage, depression higher, resulting compromised well-being mental health. Objectives. This systematic review aims to quantitatively qualitatively assess changes neuropsychological, particularly executive functioning cognition domains, electroencephalographical (EEG) effects MBIs. Methods. A was conducted using Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) three databases, Web Science, Scopus, EBSCO MedLine complete; 14,464 articles were found, 141 evaluated MBI on functioning, 16 included both qualitative quantitative variables.

BACKGROUND Breast cancer patients undergoing chemotherapy often experience high levels of stress and symptom burden. Mindful breathing virtual reality with biofeedback may offer an effective non-pharmacological intervention for management, yet its efficacy remains underexplored. OBJECTIVE This study evaluated the effect mindful in reducing severity breast chemotherapy. METHODS A three-arm parallel randomized controlled trial was conducted from August to November 2023 at a medical center Taiwan. total 82 participants were randomly assigned group (n = 25), audio training 28), control 29). Outcomes included stress, severity, physiological features such as electroencephalography, heart rate variability, respiratory signals, galvanic skin response. Machine learning analyses used identify response patterns. RESULTS Participants showed significant reduction level (p < .05) .001) compared other groups. Additionally, demonstrated improvements further confirmed superior accuracy detecting differentiating responses. CONCLUSIONS effectively reduces chemotherapy, measurable benefits. These findings highlight potential innovative, support management oncology care. CLINICALTRIAL registered on ClinicalTrials.gov under identifier NCT06541587.
