Moderate Dementia Clinical Trial
Official title:
Can Virtual Reality Reduce Depression and Agitation in Older Adults With Moderate to Severe Dementia? A Randomized Controlled Trial.
Dementia is a term used to describe a collection of symptoms including memory loss, problems
with reasoning and communication, and a reduction in a person's ability to carry out daily
activities. The most common types of dementia are: Alzheimer's disease, vascular dementia,
mixed dementia and dementia with Lewy bodies. Clinicians and families are looking for ways to
deal with this challenging group of diseases to improve quality of life, reduce depression
and agitation for individuals in long term care (LTC).
There are a variety of non-pharmacologic interventions for dementia often used in addressing
physiological and behavioral challenges, new to this category of treatment is virtual reality
(VR).
Virtual reality has been studied in mild cognitive impairment. Colleagues completed a
systematic review of non-pharmacological intervention to treat older people with dementia and
found music to be the only intervention effective, VR was not included as no studies were
found.
The Registered Nurses Association of Ontario report non-pharmacological approaches are an
important alternative to the use of antipsychotic medications. They recommend health-care
providers should consider non-pharmacological interventions wherever possible as a first-line
approach to the management of BPSD.
Virtual reality as proposed in this research will include music, library items will be
selected that are person specific, and will provide sensory stimulation. To date there is no
published research on the use the VR in moderate to severe dementia in LTC, looking at
depression.
Dementia is a term used to describe a collection of symptoms including memory loss, problems
with reasoning and communication, and a reduction in a person's ability to carry out daily
activities such as washing, dressing and cooking. The most common types of dementia are:
Alzheimer's disease, vascular dementia, mixed dementia and dementia with Lewy bodies.
Dementia is a progressive condition, which means that the symptoms will gradually get worse.
Clinicians and families are looking for ways to deal with this challenging group of diseases
to improve quality of life, reduce depression and agitation that often accompany dementia as
it progresses and individuals are placed in long term care (LTC).
There are a variety of non-pharmacologic interventions for dementia ranging from traditional
interventions such as behavioral therapy to newer interventions such as multisensory therapy.
Often used in addressing physiological and behavioral challenges, some interventions have
been shown to aid cognitive ability as well. "Cognitive stimulation," is a catchall term
referring to non-pharmacologic interventions with a cognitive focus, new to this category of
treatment is virtual reality (VR).
Virtual reality has been studied in mild cognitive impairment. A systematic review of studies
evaluating computerized cognitive training and virtual reality cognitive training
interventions for individuals at high risk of cognitive decline called mild cognitive decline
documented consistent improvement in the domains of attention, executive function, visual and
verbal memory, and also on the psychological symptoms of depression, anxiety, and apathy in
participants. Colleagues completed a systematic review of non-pharmacological intervention to
treat older people with dementia and found music to be the only intervention effective, VR
was not included as no studies were found.
The Registered Nurses Association of Ontario completed a best practice guideline on Dementia
based on current evidence in 2016. They report non-pharmacological approaches are an
important alternative to the use of antipsychotic medications, which historically have been
overused as a first-line strategy for managing behavioural and psychological systems of
dementia (BPSD). They recommend health-care providers should consider non-pharmacological
interventions wherever possible as a first-line approach to the management of BPSD.
The most well-studied and effective non-pharmacological approaches include listening to
music/music therapy, effective communication and person-centred approaches and other sensory
stimulation. Virtual reality as proposed in this research will include music, specific
library items will be selected that are person specific, and will provide sensory stimulation
in keep with the RNAO guidelines. To date there is no published research on the use the VR in
moderate to severe dementia in LTC looking at depression as the primary outcome measure.
