Virtual Reality (VR)-based meditation has shown to help reduce, stress, anxiety, sadness, and anger in younger adults. However, this has not been extensively studied in older adults. Furthermore, there are no standard guidelines on how VR mindfulness interventions should be implemented to ensure successful outcomes in different cultures and languages. The availability of affordable hardware raises the possibility of VR being used in low-income countries. The goal of this study is to describe and highlight some key considerations and challenges when implementing low-cost VR mindfulness interventions with older adults in Quito, Ecuador.

We created a guided mindfulness intervention using low-cost VR (smartphones and Destek V5 headsets) for older adults with anxiety in Quito, Ecuador. This project is a collaboration between the Technology and Aging Lab at McLean Hospital and the Universidad San Francisco de Quito in Ecuador. Our goal was to recruit 20 older adults with anxiety from various outpatient settings in Quito. We used the free “Sites in VR” app and selected different nature scenes for each intervention. The intervention consists of a total of 10 sessions each lasting 30 minutes. We assessed depression using the Geriatric Depression Scale (GDS), and anxiety with the Generalized Anxiety Disorder 7-item scale (GAD-7). In addition, we also administered the Mindfulness Attention Awareness Scale (MAAS) and the Behavior Activation for Depression scale (BADS).

At the time of writing, we have reached 100% of our recruitment goal and anticipate completing data analysis by January 2023. Qualitatively, our intervention revealed barriers to designing scalable VR Spanish language interventions in Latin America. Some of the main difficulties we encountered are described below: (i) There are very few virtual reality videos (360° videos) that are available for use with the DesTeK VS VR Headset in Spanish. We therefore, used a standardized Spanish narration to guide the mindfulness practice based on a script used in the United States. (ii) We found that majority of the available content is not suitable for mindfulness. Using the application Sites in VR remedied this concern, as it provides static 360° images, suitable for mindfulness. (iii) Not all technology necessary for VR interventions is readily available in Latin America: smartphones sold in Latin America do not always have a gyroscope sensor.

Mindfulness interventions using virtual reality may be an effective way to address stress and mood symptoms in older adults across cultures. However, there are many culture-specific aspects that must be addressed before applying these interventions in different cultures. This study, conducted in Latin America, is an initial step toward the establishment of best practices and standardized low-cost VR mindfulness intervention in older adults, and many aspects addressed here may be generalizable to other cultures, settings, and countries.

Virtual reality (VR) is a promising tool with the potential to enhance care of cognitive and affective disorders in the aging population. VR has been implemented in clinical settings with adolescents and children; however, it has been less studied in the geriatric population.

The objective of this study is to determine the existing levels of evidence for VR use in clinical settings and identify areas where more evidence may guide translation of existing VR interventions for older adults.

We conducted a systematic review in PubMed and Web of Science in November 2019 for peer-reviewed journal articles on VR technology and its applications in older adults. We reviewed article content and extracted the number of study participants, study population, goal of the investigation, the level of evidence, and categorized articles based on the indication of the VR technology and the study population.

The database search yielded 1554 total results, and 55 articles were included in the final synthesis. The most represented study design was cross-sectional, and the most common study population was subjects with cognitive impairment. Articles fell into three categories for VR Indication: Testing, Training, and Screening. There was a wide variety of VR environments used across studies.

Existing evidence offers support for VR as a screening and training tool for cognitive impairment in older adults. VR-based tasks demonstrated validity comparable to some paper-based assessments of cognition, though more work is needed to refine diagnostic specificity. The variety of VR environments used shows a need for standardization before comparisons can be made across VR simulations. Future studies should address key issues such as usability, data privacy, and confidentiality. Since most literature was generated from high-income countries (HICs), it remains unclear how this may be translated to other parts of the world.

Recently, artificial intelligence-powered devices have been put forward as potentially powerful tools for the improvement of mental healthcare. An important question is how these devices impact the physician-patient interaction.

Aifred is an artificial intelligence-powered clinical decision support system (CDSS) for the treatment of major depression. Here, we explore the use of a simulation centre environment in evaluating the usability of Aifred, particularly its impact on the physician–patient interaction.

Twenty psychiatry and family medicine attending staff and residents were recruited to complete a 2.5-h study at a clinical interaction simulation centre with standardised patients. Each physician had the option of using the CDSS to inform their treatment choice in three 10-min clinical scenarios with standardised patients portraying mild, moderate and severe episodes of major depression. Feasibility and acceptability data were collected through self-report questionnaires, scenario observations, interviews and standardised patient feedback.

All 20 participants completed the study. Initial results indicate that the tool was acceptable to clinicians and feasible for use during clinical encounters. Clinicians indicated a willingness to use the tool in real clinical practice, a significant degree of trust in the system's predictions to assist with treatment selection, and reported that the tool helped increase patient understanding of and trust in treatment. The simulation environment allowed for the evaluation of the tool's impact on the physician–patient interaction.

The simulation centre allowed for direct observations of clinician use and impact of the tool on the clinician–patient interaction before clinical studies. It may therefore offer a useful and important environment in the early testing of new technological tools. The present results will inform further tool development and clinician training materials.

Cognitive impairments are directly related to severity of symptoms and are a primary cause for functional impairment. Intraindividual cognitive variability likely plays a role in both risk and resiliency from symptoms. In fact, such cognitive variability may be an earlier marker of cognitive decline and emergent psychiatric symptoms than traditional psychiatric or behavioral symptoms. Here, our objectives were to survey the literature linking intraindividual cognitive variability, trauma, and dementia and to suggest a potential research agenda.

A wide body of literature suggests that exposure to major stressors is associated with poorer cognitive performance, with intraindividual cognitive variability in particular linked to the development of posttraumatic stress disorder (PTSD) in the aftermath of severe trauma.

In this narrative review, we survey the empirical studies to date that evaluate the connection between intraindividual cognitive variability, PTSD, and pathological aging including dementia.

The literature suggests that reaction time (RT) variability within an individual may predict future cognitive impairment, including premature cognitive aging, and is significantly associated with PTSD symptoms.

Based on our findings, we argue that intraindividual RT variability may serve as a common pathological indicator for trauma-related dementia risk and should be investigated in future studies.
