Abstract

Objective Lavender and Lemon Balm essential oils are popular in the management of older person agitation due to their ease of application, minimal side effects and low interaction with concurrent medications. This study addressed limitations in the literature to evaluate and compare effectiveness of Lavender and Lemon Balm essential oils on the agitated behaviour of older people with and without dementia living in residential aged care facilities [RACFs].Methods Forty-nine nursing home residents with dementia (n=39) and without dementia (n=10) exhibiting agitation participated in this study. Participants were randomised to a counterbalanced, repeated measures design experiment that tests the treatments Lavender, Lemon Balm, and Placebo (Sunflower oil). Treatments were administered once daily for two-weeks followed by a two-week washout period before commencing the subsequent treatment. All participants trialed all three treatments over a 10-week period. Data were collected on the Neuropsychiatric Inventory (NPI) and Cohen-Mansfield Agitation Inventory (CMAI).Results A significant difference was shown when essential oils effect were compared between the cognitive groups. Post hoc analysis reports Lemon Balm more effective in reducing NPI agitation (p = .04) and CMAI physical non-aggressive behaviour (PNAB) (p = .02) in residents without dementia. Lemon Balm less effective in reducing NPI irritability (p = 0.01) and Lavender more effective in reducing CMAI PNAB (p = 0.04) in dementia.Conclusion The findings support an opposing effect of Lemon Balm and Lavender in reducing agitated behaviour between the participant cognitive groups. There was no reduction in agitation with treatments when compared to placebo independent of cognitive groups.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
