Aroma therapy for dementia.

Complementary therapies have become more commonly used over the last decade and have been applied to a range of health problems, including dementia. Of these, aroma therapy is reported to be the most widely used in the British National Health Service (Lundie 1994) and might be of use for people with dementia for whom verbal interaction may be difficult and conventional medicine of only marginal benefit. Aroma therapy has been used for people with dementia to reduce disturbed behaviour (e.g. Brooker 1997), promote sleep (e.g. Wolfe 1996), and stimulate motivational behaviour (e.g. MacMahon 1998).
