Background: Behavioural and Psychological Symptoms in Dementia (BPSD) are frequent and a major management problem, especially for patients with severe cognitive impairment. Preliminary reports have indicated positive effects of aromatherapy using select essential oils, but there are no adequately powered placebo controlled trials . We conducted a placebo controlled trial to determine the value of aromatherapy with essential oil (melissa) for agitation in people with severe dementia.
