A Weighted Buddy can be a powerful non-pharmacological tool used in dementia care. It combines the principles of Deep Pressure Stimulation (DPS) with the psychological benefits of a comfort object.
The Primary Mechanism: Deep Pressure Stimulation (DPS)
The core therapeutic benefit comes from the weight. Similar to a weighted blanket, the gentle, firm pressure applied to the body (typically the lap when sitting) provides proprioceptive input. This input helps to regulate the nervous system by:
- Activating the Parasympathetic Nervous System: It helps shift the body from a state of high alert (sympathetic “fight-or-flight”) to a state of calm (parasympathetic “rest-and-digest”).
- Modulating Neurotransmitters: DPS is believed to trigger the release of calming neurotransmitters, such as serotonin and dopamine, while reducing the levels of the stress hormone cortisol.
Specific Benefits for Dementia Care
The combination of DPS and the “Buddy” form factor addresses several common challenges associated with dementia:
1. Reduces Anxiety, Agitation, and Restlessness:
- The calming effect of DPS can significantly decrease feelings of anxiety and agitation, which are common symptoms, especially during “sundowning.”
- Holding or stroking the buddy provides a soothing, repetitive motion that can channel restless energy and reduce fidgeting.
2. Provides Comfort and Security:
- The weight provides a grounding sensation that can make a person feel more secure and present in their environment.
- The form of a soft animal or lap pad is non-threatening and can evoke feelings of comfort and safety, similar to a hug.
3. Combats Loneliness and Promotes Nurturing:
- The “Buddy” can serve as a constant companion, helping to alleviate feelings of isolation and loneliness.
- It can trigger a nurturing instinct, giving the person a sense of purpose and responsibility as they “care for” the animal. This can be particularly meaningful for individuals who were once pet owners themselves.
4. Decreases Unsafe Wandering:
- A Weighted Buddy placed on the lap can provide enough sensory feedback to make a person feel more settled and less inclined to stand up and wander without purpose. It gives them a focus point while seated.
5. Improves Engagement and Communication:
- The buddy can act as a social bridge. A caregiver or family member can ask about the “pet” or “baby,” opening a channel for communication that is less direct and potentially less stressful than personal questions.
6. Can Improve Sleep:
- By promoting a state of calm and reducing anxiety before bedtime, using a Weighted Buddy during quiet time in the evening can help facilitate an easier transition to sleep.
Practical Considerations and Best Practices for Implementation
For this tool to be effective and safe, healthcare professionals should consider the following:
- Choosing the Right Weight: The general guideline is 10% of the person’s body weight. A Buddy that is too heavy can be a safety risk, restricting movement or circulation.
- Choosing the Right Form: Consider the person’s life history and preferences. A person who loves cats may respond well to a weighted cat, while a person who loves dogs may respond well to a weighted dog. The goal is a positive association.
- Introduction: Introduce the Buddy gently. Don’t just place it on their lap. Present it as a gift or a visitor, e.g., “Look who came to see you today.” Observe their reaction and proceed only if it is positive.
- Mobility: Ensure the person can remove the Buddy independently if they wish.
- Individualised Approach: A Weighted Buddy is not a universal solution. Some individuals may not respond to it or may find it distressing. It is essential to monitor the person’s reaction and discontinue use if it causes agitation.
In summary, a Weighted Buddy is a valuable therapeutic tool that leverages deep pressure stimulation and psychological comfort to address some of the most challenging behavioural and emotional symptoms of dementia, promoting calm, security, and a sense of purpose. It should always be implemented thoughtfully and with careful consideration for the individual’s safety and preferences.
