D’Andrea F, Tischler V, Dening T, Churchill A. Olfactory stimulation for people with dementia: A rapid review. Dementia. April 2022. doi:10.1177/14713012221082377

This study used a mixed methods approach to synthesise the evidence on olfactory stimulation in dementia care. In particular, this review (1) synthesised the qualitative and quantitative evidence on the impact of olfactory stimulation on responsive behaviours, cognitive function, communication, quality of life, pain and physical functioning; (2) assessed the effects of different types of scents used and identify, if any, patterns in their effects and (3) reviewed the different ways in which olfactory stimuli are administered and identify, if any, patterns in their effects.

Mixed results were reported on the benefits of olfactory stimulation on responsive behaviours and cognitive function. Although the evidence available is limited, encouraging results were found regarding olfactory stimulation and increased sleep duration, food intake and improved balance. Overall, the review shows promising results that support further investigation of olfactory stimulation as a nonpharmacological intervention for people with dementia.
