Systematic Review and Meta-Analysis Confirm the Moderate Efficacy of High-Frequency r-TMS in Alzheimer's Disease: Mediating Effects of Anhedonia-Apathy and Add-On Motor-Cognitive Excersizes.

OBJECTIVES: Alzheimer's disease (AD) presents a major global health issue of significant socio-economic impact. Pharmacological treatments for AD have limited efficacy, prompting the exploration of alternative therapies, such as repetitive transcranial magnetic stimulation (rTMS), a promising non-invasive technique to enhance cognitive function in AD patients. Our systematic review and meta-analysis aim to evaluate the efficacy of rTMS in relation to cognitive function in AD patients, identify optimal rTMS stimulation parameters, and understand the underlying neural mechanisms. METHODS: We conducted a comprehensive literature search in PubMed using predefined search terms to identify original research articles investigating the effects of rTMS on cognitive function in AD patients. We selected only randomized controlled trials (RCTs) with sufficient quantitative data for comparing active rTMS to the sham-coil treatment, and then performed a random effects meta-analysis using standardized mean differences (SMDs) to synthesize the effects across studies. RESULTS: The systematic review included 22 studies, among which 14 RCTs met our criteria for meta-analysis. High-frequency rTMS, particularly targeting the dorsolateral prefrontal cortex (DLPFC), evoked significant cognitive improvements in AD patients, with a moderate positive effect size of rTMS on cognitive function (Hedges' g=0.580, 95% CI [0.268, 0.892], p<0.001), albeit with substantial heterogeneity (I²=59%). Funnel plot asymmetry and Egger's test suggested a potential publication bias, but fail-safe N analysis indicated a robust finding. Moreover, anhedonia-apathy symptoms and motor-cognitive exercises mediated the efficacy of tTMS in ameliorating cognitive functioning across several studies. CONCLUSION: rTMS demonstrates moderate efficacy in improving cognitive function in AD-patients, most distinctly with high-frequency rTMS stimulation protocols targeting the DLPFC area. The meta-analysis support rTMS as a viable therapeutic intervention for cognitive enhancement in AD. Future promising research should focus on personalized treatment strategies targeting mediating factors, baseline connectivity patterns, and TMS-induced neuroplasticity in AD.

Virtual Reality (VR) Device with Integrated Biofeedback Sensors (ReViSide) to Cope with Emotional Burnout State Among Employees Experiencing Stress at Workplace: Problem Overview and Action Plan.

INTRODUCTION: In this study we examine the issue of employee burnout, caused by long-term exposure to workplace stressors, considering its complex phenomenology in the context of contemporary psychological and psychiatric views. Towards the development of innovative technologies to correct burnout in the context of psychosocial rehabilitation, we present our study protocol involving the ReViSide virtual reality (VR) and biofeedback intervention, including monitoring of respiratory rates and EEG rhythms. METHODS: The randomized controlled trial protocol includes adult participants aged 18 to 65 years (n=140) who exhibit emotional burnout in the workplace. The intervention group will undergo a course of VR correction (ReViSide), while the control group receives a standard psychocorrection. The primary endpoint will be level of emotional burnout to the Maslach Burnout Inventory (MBI). We shall also assess anxiety, depression, asthenia and subjective improvement in condition using validated scales (HADS, HARS, HDRS, VAS-A, PGI-C). RESULTS: We shall test our hypothesis that the VR-correction group will show significant improvements in MBI scores, particularly in emotional exhaustion, depersonalization, and personal accomplishment, compared to the control group. Secondary outcome measures are likewise expected to demonstrate more prominent improvements in the VR group, correlating with the magnitude of burnout reduction to MBI. Analysis of EEG data may reveal changes in alpha rhythm patterns during VR sessions, potentially correlating with reduced distress levels. CONCLUSIONS: We designed this study to test the integration of an interdisciplinary approach for treating burnout, highlighting the ReViSide technology. Confirming the efficacy of this approach for psychosocial rehabilitation targeting burnout states among employees should improve their stress resilience, daily motivation, and work productivity in the context of the modern high working pressure environment and demanding corporate culture.
