This evidence theme on Namaste Care is a summary of the issues identified in a scoping review of dementia research. If you need more information on this topic, try using the PubMed search below.
There is plenty of support for Namaste Care with aged care providers. [2] At the same time, there is still little research evidence demonstrating the benefits of the overall program for the person with dementia. [5] However, one review assessed the evidence of the effectiveness of the individual components of the program. [2] It found generally positive evidence of benefits for the following elements of Namaste Care:
- Lavender for reducing agitation and other responsive behaviours and improving sleep quality
- Diffused or massaged lemongrass and eucalyptus oil for reducing agitation
- Multisensory stimulation for reducing verbal agitation
- Group music interventions, including singing, for reducing anxiety and enhancing social participation
- Exposure to nature, including videos, live and robotic animals, and cuttings from the garden for improving mood
- Offering dolls to people living with dementia for improving communication and social interaction, and reducing anxiety, responsive behaviours, and social isolation
- Exposure to pets, especially dogs, for evoking positive responses from people living with dementia in care homes. This includes improvement in mood, communication, and sense of self-worth, along with a reduction in depression, aggression, and agitation. (It is worth noting that people living with dementia responded to a robot dog with almost the same level of engagement as with a live dog.) [2]
Some elements of Namaste Care are supported by less conclusive evidence as different studies reported contradictory findings. These elements include:
- Bright light therapy for improving sleep and reducing depression
- Playing background music during mealtimes for reducing responsive behaviours
- Massage, although generally well tolerated by participants, had no consistent effect on responsive behaviours
- Food and drink offerings for increasing hydration and nutrition.
The conclusions from the review might help carers decide which elements of Namaste Care to try, however, it does not guide them in knowing the best combinations to use, or their ideal duration. Interactions might occur between multiple components (e.g., massage and aromatherapy) that strengthen or lessen the overall impact of the program. [2]
