Neurocognitive Assessment in Virtual Reality Through Behavioral Response Analysis

Extended reality for neurocognitive assessment: A systematic review

OBJECTIVE

The objective of this study is to evaluate the effectiveness, feasibility, and clinical relevance of extended reality (XR) technologies for neurocognitive assessment.

METHODS

A systematic review of published literature on augmented reality (AR), mixed reality (MR) and fully immersive virtual reality (VR) technologies for neurocognitive assessment was conducted. Studies were included if they evaluated XR for assessing neurocognitive domains, with outcomes related to diagnostic accuracy or usability.

RESULTS

28 studies met the inclusion criteria. VR-based tools (n = 26) were the most commonly utilized, offering immersive environments for assessing several cognitive domains including memory, attention and executive function. AR applications (n = 2) were less frequently utilized but showed promising potential in cognitive impairment detection. No studies utilized MR technology for assessing neurocognitive functions. XR technologies were found to be more sensitive, ecologically valid, and engaging compared to traditional assessment tools.

DISCUSSION

XR technologies offer a transformative approach to neurocognitive assessments by providing immersive, interactive environments that go beyond the limitations of traditional methods. Despite their potential, XR technologies face limitations such as high costs and technical challenges like motion sickness. Future efforts should focus on improving accessibility, user interfaces, and incorporating social and emotional dynamics to create more realistic assessments.

Patient experiences of virtual care across specialist neuroscience and psychiatry clinics related to the second wave of the COVID-19 pandemic in Calgary, Alberta

Purpose

The emergence of the COVID-19 (SARS-CoV-2) pandemic has led to public health restrictions and a shift towards virtual care and telehealth. The aim of this study was to explore barriers and facilitators of virtual care from the perspective of neurological and psychiatric patients.

Methods

One-on-one interviews were conducted remotely using telephone and online video teleconferencing. There was a total of 57 participants, and a thematic content analysis was conducted using NVivo software.

Results

The two main themes were (1) virtual health service delivery and (2) virtual physician/patient interaction, with subthemes around how virtual care improved accessibility of care for patients and improved patient-centered care; how privacy and technical issues impact patients using virtual care; and the need for relationality and connection between health care providers and patients while using virtual care.

Conclusions

This study showed that virtual care can increase accessibility and efficiency for patients and providers, indicating its potential for ongoing use in the delivery of clinical care. Virtual care was found to be an acceptable mode of healthcare delivery from the perspective of patients; however, there is a continued need for relationship-building between care providers and patients.

The Use of Immersive Environments for the Early Detection and Treatment of Neuropsychiatric Disorders

Neuropsychiatric disorders are highly prevalent conditions with significant individual, societal, and economic impacts. A major challenge in the diagnosis and treatment of these conditions is the lack of sensitive, reliable, objective, quantitative tools to inform diagnosis, and measure symptom severity. Currently available assays rely on self-reports and clinician observations, leading to subjective analysis. As a step toward creating quantitative assays of neuropsychiatric symptoms, we propose an immersive environment to track behaviors relevant to neuropsychiatric symptomatology and to systematically study the effect of environmental contexts on certain behaviors. Moreover, the overarching theme leads to connected tele-psychiatry which can provide effective assessment.

Technological Competence Is a Pre-condition for Effective Implementation of Virtual Reality Head Mounted Displays in Human Neuroscience: A Technological Review and Meta-Analysis

Immersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent to display, sound, motion tracking, navigation, ergonomic interactions, user experience, and computer hardware that should be considered by the researchers. Subsequently, a meta-analysis of 44 neuroscientific or neuropsychological studies involving VR HMD systems was performed. The meta-analysis of the VR studies demonstrated that new generation HMDs induced significantly less VRISE and marginally fewer dropouts. Importantly, the commercial versions of the new generation HMDs with ergonomic interactions had zero incidents of adverse symptomatology and dropouts. HMDs equivalent to or greater than the commercial versions of contemporary HMDs accompanied with ergonomic interactions are suitable for implementation in cognitive neuroscience. In conclusion, researchers' technological competency, along with meticulous methods and reports pertinent to software, hardware, and VRISE, are paramount to ensure the health and safety standards and the reliability of neuroscientific results.
