The use of aromatherapy to treat behavioural problems in dementia

Behavioural and psychological symptoms in dementia (BPSD) are common and distressing to both patients and carers. The use of antipsychotics to treat BPSD is associated with a high burden of side‐effects and alternative strategies are required. Aromatherapy is an option that has been recommended for use in dementia. We aimed to review the evidence supporting the use of aromatherapy in BPSD.
