Role of VR based Games in Treating Dementia Patients

Dementia is a group of symptoms that interfere with daily functioning, affecting memory, language, problem-solving, and other cognitive abilities. It is a broad term that encompasses various conditions, with Alzheimer’s disease being the most common cause. As the population ages, the prevalence of dementia is expected to increase, making it a significant public health concern. Virtual reality (VR) technology has been explored as a potential tool to improve the lives of individuals with dementia, offering a unique opportunity for entertainment, socialisation, and cognitive stimulation.

The causes and symptoms of dementia include various factors that can lead to cognitive decline and interfere with daily functioning. Some common causes of dementia mentioned in the sources are:

1. Brain Injuries: Traumatic brain injuries (TBI) can cause memory loss, depression, explosiveness, and impaired speech, contributing to dementia symptoms.
2. Immune System Disorders: Conditions where the body’s immune system attacks nerve cells can lead to dementia, such as in multiple sclerosis.
3. Metabolic or Endocrine Issues: Thyroid problems, low blood sugar, and imbalances in sodium, calcium, or vitamin B-12 levels can result in dementia-like symptoms or personality changes.
4. Nutritional Deficiencies: Lack of essential nutrients like thiamin (vitamin B-1), vitamin B-6, vitamin B-12, copper, or vitamin E can lead to dementia symptoms.
5. Medication Side Effects: Some medications or their interactions can cause dementia-like symptoms in individuals.

The symptoms of dementia can vary depending on the cause and may include:

• Memory loss
• Communication difficulties
• Confusion and disorientation
• Problems with reasoning and problem-solving
• Personality changes
• Depression, anxiety, and agitation
• Inappropriate behaviour
• Hallucinations and paranoia

VR-based games and applications are designed to engage individuals with dementia in various activities, such as:

• Cognitive Training: Games that challenge memory, attention, and problem-solving skills, helping to maintain cognitive function.
• Social Interaction: Virtual environments that facilitate social interaction, reducing feelings of loneliness and isolation.
• Emotional Expression: Games that allow individuals to express emotions and creativity, promoting emotional well-being.
• Therapeutic Interventions: VR-based therapies that target specific symptoms, such as agitation, aggression, and anxiety.

The key benefits of using virtual reality (VR) in treating dementia patients include:

1. Reducing Aggressiveness: The study found that VR therapy had a statistically significant effect on reducing aggressive behaviours, such as physical aggression and loud vocalisation, in dementia patients.
2. Improving Memory and Cognition: VR can help stimulate memory and cognitive function in dementia patients. The studies reported that VR experiences helped patients recall old memories and contributed to an improvement in their relationships with caregivers.
3. Enhancing Quality of Life: VR-based interventions can enhance the quality of life for individuals with dementia by reducing feelings of loneliness and increasing social interaction.
4. Providing Cognitive Stimulation: VR-based games and activities can provide cognitive stimulation, helping to maintain cognitive function in dementia patients.

Some examples of virtual reality programs used in treating dementia patients include:

1. Virtual Environments: Patients with dementia accessed five different virtual environments, including a cathedral, a forest, a sandy beach, a rocky beach, and the countryside, over 16 sessions. These environments helped patients recall old memories and improve their relationships with caregivers.
2. Personal Space Option: Virtual reality creates a “personal space” option for patients in long-term care, allowing them to experience activities they may no longer have access to in daily life due to their declining health and secure environments. This personalised approach can provide relaxation and respite for dementia patients.
3. Tranquil Scenes: Tranquil virtual reality scenes have been found to effectively distract patients, reduce stress levels without medication, and help uncommunicative patients speak more. These experiences can deepen interactions between caregivers and patients, offering unique insights into the lives of dementia patients.
4. A Walk Through Dementia: Alzheimer’s Research UK has developed “A Walk Through Dementia” videos, offering 360-degree experiences designed to immerse viewers in the shoes of someone living with dementia in everyday situations. These videos aim to increase understanding, empathy, and awareness of the challenges faced by dementia patients.

Virtual reality (VR) has emerged as a promising tool for treating dementia, offering unique benefits compared to traditional treatments. One major advantage of VR is its ability to provide personalised and engaging experiences tailored to individual patients. Unlike traditional treatments that may lack customisation, VR allows developers to recreate specific environments, such as a patient’s home or a meaningful place, using 360-degree video. This personalised approach can enhance the effectiveness of interventions by triggering memories and emotions that are difficult to replicate in standard care settings.

Moreover, VR offers a novel way to stimulate memory and cognition in dementia patients. Studies have shown that VR experiences can help individuals recall old memories, contributing to improvements in their relationships with caregivers and overall quality of life. The immersive nature of VR environments can engage patients in cognitive tasks, social interactions, and emotional experiences, providing a richer and more satisfying quality of life than traditional treatments.

In terms of effectiveness, VR has shown promising results in reducing aggressiveness and improving well-being in dementia patients. Research indicates that VR therapy can significantly reduce aggressive behaviours and enhance mood and engagement levels among patients. Caregivers have reported deeper and improved interactions with patients after VR sessions, suggesting that VR can offer valuable insights into patients’ lives and enhance the caregiving experience.

While traditional treatments for dementia often focus on pharmacological interventions or standard cognitive exercises, VR stands out for its ability to provide a multi-sensory and interactive experience that can address cognitive, emotional, and social aspects of dementia care. By offering a more holistic approach to treatment, VR has the potential to complement traditional therapies and enhance the overall well-being of individuals living with dementia. Further research and development in the field of VR for dementia care are essential to fully understand the comparative benefits and limitations of VR versus traditional treatments and to optimise the use of this innovative technology in improving the lives of dementia patients.

The technical requirements for implementing virtual reality programs in aged-care settings include:
