Virtual reality can help improve quality of life for dementia patients, study

These memories not only provided positive mental stimulation for the patients but helped their caregivers learn more about their lives before care, thereby improving their social interaction.

Virtual reality (VR) technology may vastly improve the quality of life for people with dementia by helping them recall past memories, reduce aggression and improve interactions with caregivers, a study has found.

Eight patients aged between 41 and 88 who are living with dementia including Alzheimer’s disease and Huntington’s disease took part in the study published in Proceedings of the SIGCHI Conference on Human Factors in Computing Systems.

Each patient used a VR headset to ‘visit’ one of five virtual environments (VEs) of a cathedral, a forest, a sandy beach, a rocky beach, and a countryside scene, said researchers from the University of Kent in the UK.

Sixteen sessions were monitored with feedback gathered from patients and their caregivers.

“VR can clearly have positive benefits for patients with dementia, their families and caregivers,” Jim Ang from the University of Kent.

“It provides a richer and more satisfying quality of life than is otherwise available, with many positive outcomes,” Ang said.

One key finding was that VR helped patients recall old memories by providing new stimuli difficult to achieve, due to ill-health, or inaccessible within a secure environment.

For example, one patient recalled a holiday when they saw a bridge in the VE because it reminded them of that trip while another remembered a holiday where they visited a market.

These memories not only provided positive mental stimulation for the patients but helped their caregivers learn more about their lives before care, thereby improving their social interaction.

At an arts session some weeks later, one of the patients who had taken part commented that it had been ‘brilliant’.

He appeared to enjoy reminiscing about the experience and was inspired to draw a seaside picture, suggesting that his VR experience had had a positive effect on his mood and motivation to engage with the art session.

The patients also demonstrated their own choices during the experiment, with some keen to explore different VEs within a session, while others explored the same environment repeatedly.

“With further research it will be possible to further evaluate the elements of VEs that benefit patients and use VR even more effectively,” he said.
