What data supports the effectiveness of the treatment Audiovisual Stimulation VR System for Alzheimer's Disease?

Research shows that virtual reality (VR) treatments can help improve cognitive functions like memory and attention in people with dementia, including Alzheimer's. A study found that VR-based navigation training improved real-life cognitive skills, and another review highlighted VR's positive impact on emotional and social wellbeing. ^{1 2 3 4 5}

Is VR audiovisual stimulation safe for humans?

Research shows that virtual reality (VR) technology, including audiovisual stimulation, is generally safe for older adults, including those with Alzheimer's disease. Most participants in studies could complete VR tasks without significant side effects, and there were no major increases in symptoms like simulator sickness. ^{1 2 6 7 8}

How is the VR Audiovisual Stimulation treatment different from other Alzheimer's treatments?

The VR Audiovisual Stimulation treatment is unique because it uses immersive virtual reality technology to engage patients in cognitive training, which can improve navigation skills and cognitive function in daily life. Unlike traditional treatments, this approach leverages interactive and immersive environments to potentially enhance memory and attention in Alzheimer's patients. ^{1 2 5 9 10}

What is the purpose of this trial?

This is a single-blind, sham-controlled, clinical trial that aims to evaluate the safety, tolerability, and feasibility of delivering audiovisual stimulation via a Virtual Reality (VR) headset to people cognitively impaired due to Alzheimer's and cognitively unimpaired people.

Treatment Details

Interventions

• Audiovisual Stimulation VR System

Trial Overview The study tests if it's safe and feasible to use a VR headset to provide audiovisual stimulation to people with mild Alzheimer's and healthy aging individuals. It’s single-blind, meaning only the participants won’t know if they’re getting the real treatment or a sham (fake) version.

Participant Groups

Group I: Active and Sham Audiovisual Stimulation (Mild AD and MCI due to AD): Experimental Treatment 1 Intervention

Both active and sham stimulation conditions will be delivered to 25 cognitively impaired participants to demonstrate the mechanism of action of the intervention.

Group II: Active and Sham Audiovisual Stimulation (Cognitively Healthy): Experimental Treatment 1 Intervention

Both active and sham stimulation conditions will be delivered to 25 healthy participants to demonstrate the mechanism of action of the intervention.

Findings from Research

Current virtual reality (VR) technologies for Alzheimer's disease applications are underutilizing immersive features, often relying on conventional 2D displays instead of fully engaging 3D environments.

To enhance the effectiveness of VR in diagnosing and training for Alzheimer's, improvements such as advanced head-mounted displays, multi-sensory interactions, and neuro-physiological feedback are recommended, along with making these technologies accessible for home and nursing home use.

A case study of a man with early Alzheimer's disease showed that he could successfully learn to navigate in a virtual reality environment, indicating potential for cognitive training in AD.

Feedback from his caregiver suggested that this training not only improved his navigation skills in the virtual setting but also translated to real-life benefits, such as better driving skills and overall cognitive improvement at home.

A scoping review of 19 studies found that Virtual Reality (VR) technologies can positively impact the emotional wellbeing of persons with dementia, with emotional outcomes being the primary focus in 89.5% of the studies.

While VR shows promise in enhancing quality of life for people with dementia, there is a need for further exploration of its effects on social engagement and personhood, as well as customization of VR tools for different sub-groups.

A virtual reality driving simulator (VRDS) was tested on 11 participants with varying levels of dementia over 10 sessions, showing a significant 44.4% improvement in spatial cognition as measured by the Morris Water test after the intervention.

Participants not only improved their spatial skills but also progressed to more challenging levels of the game and reported better mood, suggesting that regular use of the VRDS could be beneficial for older adults with cognitive impairments.

Virtual reality (VR) intervention significantly improves cognitive function in older adults with mild cognitive impairment or dementia, showing moderate positive effects on overall cognition, attention, memory, and global cognition based on a meta-analysis of 11 studies with 359 participants.

VR intervention also positively impacts motor function, particularly balance, but does not show significant improvements in visuospatial ability or gait performance, indicating its potential as a beneficial non-drug treatment option.

Audio Visual Stimulation (AVS) is a non-drug intervention that has shown effectiveness in enhancing performance and managing symptoms, with potential new applications for improving sleep and reducing pain.

Despite its clinical use, there is a need for more standardized research methods and clearer definitions in AVS studies to better evaluate its clinical outcomes and mechanisms of action.

Over 80% of older adults, both with and without Alzheimer's disease, successfully completed a virtual reality (VR) navigation task, indicating that VR can be a feasible tool for cognitive assessment in this population.

While most participants tolerated the VR experience well, only 60% completed the eye tracking component, with calibration issues being a common barrier, particularly among those with Alzheimer's disease.

The study involving six persons with dementia showed that they could effectively interact with a virtual reality environment, indicating that VR can be a useful tool for assessing functional behavior in a realistic setting.

Participants did not experience significant simulator sickness or negative impacts on their psychological and physical well-being, suggesting that VR technology is safe for use among individuals with dementia.

Video prompting was found to be effective in helping individuals with mild and moderate Alzheimer's disease perform daily activities, showing similar effectiveness to verbal instructions and static pictorial cues.

Social validation assessments indicated that observers rated the performance of patients using video prompting more favorably compared to the other strategies, suggesting a preference for this method in supporting daily activities.

The interactive multimedia internet-based system (IMIS) significantly improved cognitive function in patients with Alzheimer's disease when combined with an integrated psychostimulation program (IPP), as shown by sustained improvements in the Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog) and Mini-Mental State Examination (MMSE) over 24 weeks.

Patients receiving only the IPP showed better outcomes than those on cholinesterase inhibitors alone, but the cognitive benefits from the IMIS were greater and maintained longer, highlighting its potential as an effective cognitive stimulation tool for Alzheimer's patients.
