Virtual reality working memory training improves cognitive performance of acute and remitted patients with major depressive disorder

Effects of virtual reality technology on anxiety and depression in older adults with chronic diseases: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Previous research has demonstrated the effectiveness of virtual reality (VR) technology in many application areas. However, there is a clear gap in the literature regarding its effects on depression and anxiety in older adults with chronic diseases.

AIMS

This review aimed to assess the effectiveness of VR interventions for depression and anxiety in older adults with chronic diseases.

METHODS

Seven electronic databases were systematically searched from their inception to April 9, 2024. Two researchers evaluated methodological quality using RoB (version 2.0) and performed meta-analyses using RevMan (version 5.4) and Stata (version 16.0) software.

RESULTS

This review included 19 randomized controlled studies. Meta-analysis revealed that VR significantly improved depression (standard mean difference [SMD] = -0.67, 95% confidence interval [CI] [-0.90, -0.45], p < .00001) and anxiety (SMD = -0.76, 95% CI [-0.95, -0.57], p < .00001) in older adults with chronic diseases, improved their quality of life (SMD = 0.39, 95% CI [0.17, 0.61], p = .0006) and positive emotions (SMD = 5.65, 95% CI [3.61, 7.69], p < .00001), and relieved stress (SMD = -1.08, 95% CI [-1.52, -0.64], p < .00001). However, the difference in self-efficacy was statistically non-significant (SMD = 1.01, 95% CI [-0.48, 2.50], p = .19).

LINKING EVIDENCE TO ACTION

The results of this systematic review provide important evidence for developing interventions to improve the mental health of older adults with chronic diseases.

Effects of virtual reality-based cognitive training for adolescents with depressive episodes: A pilot randomized controlled study

Cognitive impairment is a common symptom in depression, yet few intervention strategies target adolescents. This study investigated the effects of an attention and working memory cognitive training system based on virtual reality (VRCT) in adolescents with mild to moderate depressive episodes. Adolescents with depression were randomized into a VR training group (VRG, n = 47) or a waitlist control group (WT, n = 46). The VR training consisted of three 10-min tasks per session, conducted three sessions per week for 20 sessions over 7 weeks. Forty-four healthy adolescents participated as a comparison group for baseline cognitive assessment. Cognitive functions and depressive symptoms were assessed using the Das-Naglieri cognitive assessment system, driven by the Planning, Attention, Simultaneous, and Successive (PASS) processing theory, and the Hamilton Depression Rating Scale-24 at pre- and post-intervention. Baseline results indicated significantly lower cognitive scores in patients compared to healthy adolescents. Post-intervention, the VRG demonstrated significant improvements in all four cognitive scales (effect sizes 0.56 to 0.76) and a significant reduction in depressive symptoms compared to the WT. These findings suggest that VRCT holds potential for improving cognitive impairments and alleviating depressive symptoms in adolescents with depression. Further large-scale and follow-up studies are necessary to confirm long-term benefits.

Being in Virtual Reality and Its Influence on Brain Health-An Overview of Benefits, Limitations and Prospects

BACKGROUND

Dynamic technological development and its enormous impact on modern societies are posing new challenges for 21st-century neuroscience. A special place is occupied by technologies based on virtual reality (VR). VR tools have already played a significant role in both basic and clinical neuroscience due to their high accuracy, sensitivity and specificity and, above all, high ecological value.

OBJECTIVE

Being in a digital world affects the functioning of the body as a whole and its individual systems. The data obtained so far, both from experimental and modeling studies, as well as (clinical) observations, indicate their great and promising potential, but apart from the benefits, there are also losses and negative consequences for users.

METHODS

This review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework across electronic databases (such as Web of Science Core Collection; PubMed; and Scopus, Taylor & Francis Online and Wiley Online Library) to identify beneficial effects and applications, as well as adverse impacts, especially on brain health in human neuroscience.

RESULTS

More than half of these articles were published within the last five years and represent state-of-the-art approaches and results (e.g., 54.7% in Web of Sciences and 63.4% in PubMed), with review papers accounting for approximately 16%. The results show that in addition to proposed novel devices and systems, various methods or procedures for testing, validation and standardization are presented (about 1% of articles). Also included are virtual developers and experts, (bio)(neuro)informatics specialists, neuroscientists and medical professionals.

CONCLUSIONS

VR environments allow for expanding the field of research on perception and cognitive and motor imagery, both in healthy and patient populations. In this context, research on neuroplasticity phenomena, including mirror neuron networks and the effects of applied virtual (mirror) tasks and training, is of interest in virtual prevention and neurogeriatrics, especially in neurotherapy and neurorehabilitation in basic/clinical and digital neuroscience.
