Aroma therapy is the use of pure essential oils from fragrant plants (such as Peppermint, Sweet Marjoram, and Rose) to help relieve health problems and improve the quality of life in general. The healing properties of aroma therapy are claimed to include promotion of relaxation and sleep, relief of pain, and reduction of depressive symptoms. Hence, aroma therapy has been used to reduce disturbed behaviour, to promote sleep and to stimulate motivational behaviour of people with dementia. Of the four randomized controlled trials found only one had useable data. The analysis of this one small trial showed a significant effect in favour of aroma therapy on measures of agitation and neuropsychiatric symptoms. More large-scale randomized controlled trials are needed before firm conclusions can be reached about the effectiveness of aroma therapy.

    ABSTRACT: This paper challenges the assumptions underlying many reviews and offers alternative criteria for examining evidence for nonpharmacological interventions. We evaluated 27 reviews examining interventions for persons with dementia as they relate to the issues of selection based on randomized controlled trial (RCT) design. Reviews were described by type of intervention, level of cognitive function, and criteria for inclusion. Of the 27 reviews, 46% required RCTs for inclusion and most had stringent inclusion criteria. This resulted in poor utilization of the literature and low ecological validity. Eliminating most of the available data poses a critical problem to corresponding clinical and research development. Studies meeting strict methodological criteria may not generalize to the greater population or may exclude sub-populations and interventions. Limitations of double-blind RCTs and potential design solutions are set forth based on appropriate populations, problems, interventions, and settings characteristics.

    ABSTRACT: Lavender essential oil shows evidence of sedative properties in neurophysiological and animal studies but clinical trials of its effectiveness as a treatment of agitation in people with dementia have shown mixed results. Study methods have varied widely, however, making comparisons hazardous. To help remedy previous methodological shortcomings, we delivered high grade lavender oil in specified amounts to nursing home residents whose agitated behaviours were recorded objectively. 64 nursing home residents with frequent physically agitated behaviours were entered into a randomized, single-blind cross-over trial of dermally-applied, neurophysiologically active, high purity 30% lavender oil versus an inactive control oil. A blinded observer counted the presence or absence of target behaviours and rated participants' predominant affect during each minute for 30 minutes prior to exposure and for 60 minutes afterwards. Lavender oil did not prove superior to the control oil in reducing the frequency of physically agitated behaviours or in improving participants' affect. Studies of essential oils are constrained by their variable formulations and uncertain pharmacokinetics and so optimal dosing and delivery regimens remain speculative. Notwithstanding this, topically delivered, high strength, pure lavender oil had no discernible effect on affect and behaviour in a well-defined clinical sample.Trial registration: Australian and New Zealand Clinical Trials Registry (ACTRN 12609000569202).
