The way people living with dementia experience the world can change as the disease progresses. Their sense of reality or place in time can become distorted, which can cause agitation and distress.
One of the best ways to support people experiencing changes in perception and behaviour is to manage their environment. This can have profound benefits including reducing the need for sedatives.
One such strategy is the use of dolls as comfort aids.
More appropriately referred to as "child representation", lifelike dolls (also known as empathy dolls) can provide comfort for some people with dementia.
Memories from the distant past are often more salient than more recent events in dementia. This means that past experiences of parenthood and caring for young children may feel more "real" to a person with dementia than where they are now.
Hallucinations or delusions may also occur, where a person hears a baby crying or fears they have lost their baby.
Providing a doll can be a tangible way of reducing distress without invalidating the experience of the person with dementia.
A recent case involving an aged care nurse mistreating a dementia patient's therapy doll highlights the importance of appropriate training and support for care workers in this area.
For those who do become attached to a therapeutic doll, they will treat the doll as a real baby needing care and may therefore have a profound emotional response if the doll is mishandled.
It's important to be guided by the person with dementia and only act as if it's a real baby if the person themselves believes that is the case.
Evidence shows the use of empathy dolls may help reduce agitation and anxiety and improve overall quality of life in people living with dementia.
Child representation therapy falls under the banner of non-pharmacological approaches to dementia care. More specifically, the attachment to the doll may act as a form of reminiscence therapy, which involves using prompts to reconnect with past experiences.
Interacting with the dolls may also act as a form of sensory stimulation, where the person with dementia may gain comfort from touching and holding the doll. Sensory stimulation may support emotional well-being and aid commnication.
However, not all people living with dementia will respond to an empathy doll.
The introduction of a therapeutic doll needs to be done in conjunction with careful observation and consideration of the person's background.
Empathy dolls may be inappropriate or less effective for those who have not previously cared for children or who may have experienced past birth trauma or the loss of a child.
Be guided by the person with dementia and how they respond to the doll.
The approach has attracted some controversy. It has been suggested that child representation therapy "infantilises" people living with dementia and may increase negative stigma.
Further, the attachment may become so strong that the person with dementia will become upset if someone else picks the doll up. This may create some difficulties in the presence of grandchildren or when cleaning the doll.
The introduction of child representation therapy may also require additional staff training and time. Non-pharmacological interventions such as child representation, however, have been shown to be cost-effective.
The use of more interactive empathy dolls and pet-like robots is also gaining popularity.
While robots have been shown to be feasible and acceptable in dementia care, there remains some contention about their benefits.
While some studies have shown positive outcomes, including reduced agitation, others show no improvement in cognition, behaviour or quality of life among people with dementia.
Advances in artificial intelligence are also being used to help support people living with dementia and inform the community.
Viv and Friends, for example, are AI companions who appear on a screen and can interact with the person with dementia in real time. The AI character Viv has dementia and was co-created with women living with dementia using verbatim scripts of their words, insights and experiences. While Viv can share her experience of living with dementia, she can also be programmed to talk about common interests, such as gardening.
These companions are currently being trialled in some residential aged care facilities and to help educate people on the lived experience of dementia.
While child representation can be a useful adjunct in dementia care, it requires sensitivity and appropriate consideration of the person's needs.
People living with dementia may not perceive the social world the same way as a person without dementia. But a person living with dementia is not a child and should never be treated as one.
Ensure all family, friends and care workers are informed about the attachment to the empathy doll to help avoid unintentionally causing distress from inappropriate handling of the doll.
If using an interactive doll, ensure spare batteries are on hand.
Finally, it is important to reassess the attachment over time as the person's response to the empathy doll may change.
