Background: What is dementia?
• Not a part of normal aging
• Progressive neurodegenerative brain disorder
• Symptoms• Memory loss
• Difficulties with thinking, problem-solving or language
• Severe enough to reduce a person's ability to perform everyday activities

What Goes
![Page 4: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/4.jpg)
Not Giving Up
• Yes, brain function is diminished and there are severe problems
• But we need to build on what remains.
• There is still a capacity to enjoy
• There is still an ability to learn, if we use the parts of the brain that remain available
![Page 5: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/5.jpg)
What Stays?
• Emotions
• Motor Control (in many cases)
• Reinforcement/Implicit Learning
• Reward Seeking/Enjoyment
• Sensing
• Learned skills (procedural/automatic)• Dancing
• Playing piano
• Reading

What is the problem we are trying to solve?
Responsive Behaviours• 46% of residents exhibit some level of
aggressive behavior (screaming, hitting, wandering); on the rise (www.oltca.com)
• The need to attend to agitated behaviour is immediate, 24/7, takes priority
• It is time and resource consuming, stressful, disruptive to the environment
• Burden on residents & staff
![Page 7: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/7.jpg)
Responsive Behaviours in LTCs• Pharmacological intervention
• Overprescribed• More than 40% of people with dementia taking anti-psychotic medications
• Expensive: $38m annually
• Side effects: falls, stroke, death
• Push in Canada to reduce use of inappropriately prescribed anti-psychotics (www.cfhi-fcass.ca)
• Medicalized view: Treatment of symptoms not underlying cause of distress
(Penrod et al., 2007)
![Page 8: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/8.jpg)
• Problem behaviour is an expression of an unmet need (physical, social, emotional)
• Ideal solution • Uncover root cause of behaviour
• Individual characteristics (health conditions, personal history) and environmental triggers
• Problem• Communication becomes increasingly difficult as
dementia progresses
• Facilities are often under staff
• Our technological solution…
Unmet Needs
(Penrod et al., 2007)

Solution: Technology to help with the management of responsive behaviours in LTCs
AMBIENTAvailable in the environment
for easy access
AUGMENTINGExisting programming and
activities
ACTIVITIESProvide anytime access to
engaging activities

Person-centred Care
• Person centred-care in dementia
• Activities that were related to an individuals’ background resulted in
• More engagement
• More positive affect
• Fewer responsive behaviours
(Buron, 2008 – as cited in Nowell et al., 2013; Penrod et al., 2007)

The Need for Learning
• As dementia progresses
• Creating new explicit memories becomes impossible
• We need to utilize the implicit memory system
• Implicit Memory uses different brain processes at the relatively unaffected back of the brain
![Page 12: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/12.jpg)
Developing Usable Activities• 1-1 continuous support by
caregivers trained in Montessori principles and beh management
• Ideal, but costly and impractical
• The Design Opportunity• 24x7 available ambient activities
in the environment
• Linked to beh management systems
• Desired Outcomes• Retaining functions otherwise lost
• Creating engagement
• Improving well-being

The Research
![Page 14: New and Innovative Ambient Technologies for Dementia · PDF fileNew and Innovative Ambient Technologies for Dementia Andrea Wilkinson & Mark Chignell TRO 2017 Annual Conference London,](https://reader036.fdocuments.net/reader036/viewer/2022081517/5aa8370f7f8b9a9a188b486b/html5/thumbnails/14.jpg)
Research Questions
1. Do ambient technologies increase meaningful engagement with target activities?
2. Does the use of ambient technologies decrease responsive behaviours, and use of anti-psychotic medication?
3. What impact does ambient technology have on cognitive and emotional status?
4. What is the impact of ambient technology on staff and family (e.g., satisfaction and system usability)?
