The impact of interference between these tasks is observed by comparing the performance of a single task with that of the same task when associated with a second task, known as the dual-task effect (DTE). The decline in these functions due to aging and the associated increase in DTE might impair basic functions involving mobility, consequently increasing the risk of falls. Thus, this study aims to evaluate the DTE in functional mobility tasks across young, middle-aged, and older adults and to examine how different types of secondary tasks affect DT performance.</p><p><strong>Methods: </strong>This laboratory-based cross-sectional observational study involved forty-four young adults (32.5 ± 6.9 years), thirty-five middle-aged adults (54.6 ± 6.3 years), and twenty-eight older adults (73.9 ± 7.0 years).

Post-intervention analysis provided low certainty evidence that VR training reduced depression (SMD = -0.47; 95% CI: -0.88, -0.05, <i>p</i> = 0.03), but there was no significant effect on anxiety (SMD = -0.25; 95% CI: -0.53, 0.03, <i>p</i> = 0.08) and activities of daily living (SMD = 0.34; 95% CI: -0.05, 0.73, <i>p</i> = 0.09). Subgroup analysis indicated that participants under 60 years old who received VR intervention had a significant reduction in depression scores (SMD = -1.13; 95% CI: -1.89, -0.37, <i>p</i> = 0.004) compared with the control group. Those with moderate depression (SMD = -1.02; 95% CI = -1.96 to -0.07, <i>p</i> = 0.04) and intervention that lasted more than 6 weeks (SMD = -1.16; 95% CI: -1.87, -0.44, <i>p</i> = 0.002) also showed lower scores.</p><p><strong>Conclusions: </strong>Due to heterogeneity concerns and the poor quality of included studies, our meta-analysis that provided evidence with very low certainty indicates that VR technology may be a beneficial approach for improving the psychological health issues faced by stroke survivors, helping to reduce their depression, but has no significant effect on reducing anxiety and improving their activities of daily life. However, additional comprehensive research is required to reinforce these conclusions. Specifically, future research needs to involve larger scale and more rigorous approaches, utilizing tailored VR interventions to further improve patient well-being.

While EF-related cognitive decline has been extensively studied in late-onset Parkinson's disease (LOPD), research on EOPD remains limited. Addressing this gap, this study uniquely employed functional near-infrared spectroscopy (fNIRS), a technique well-adapted for assessing patients with motor challenges, to explore EF-related neural mechanisms in EOPD patients with mild cognitive impairment.</p><p><strong>Methods: </strong>This study included 30 patients with PD, classified into distinct cognitive profiles based on comprehensive assessments of their cognitive function. To assess functional changes in the prefrontal cortex (PFC) we administered a verbal fluency test to evaluate EF during task performance. In the resting state, we recorded neural activity and analyzed the amplitude of low-frequency fluctuations (ALFF) to assess spontaneous brain activity.</p><p><strong>Results: </strong>During executive tasks, patients with EF-dominant impairment (EOPD-EL) showed increased activation in the dorsolateral prefrontal cortex (DLPFC) and medial prefrontal cortex (mPFC), indicating disrupted balance between the executive and default mode networks. Resting-state analysis revealed reduced spontaneous activity in the ventrolateral prefrontal cortex (VLPFC), suggesting impaired regulatory efficiency in these regions. These findings support the dual syndrome hypothesis in EOPD, with EF dysfunction as a primary deficit that may lead to secondary cognitive challenges.</p><p><strong>Conclusion: </strong>This study underscores the central role of PFC dysfunction in EOPD-related EF impairment, identifying abnormalities in the DLPFC, mPFC, and VLPFC as key contributors to cognitive decline. These results lay the groundwork for early detection of EF deficits and inform targeted interventions to mitigate cognitive decline in EOPD.</p>","PeriodicalId":16160,"journal":{"name":"Journal of integrative neuroscience","volume":"24 5","pages":"36989"},"PeriodicalIF":2.5,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
