Considering olfactory stimulation for adults with age-related dementia.

Behavioral interventions and activities for adults with age-related dementias sometimes use olfactory stimulation; however, limitations to the usefulness of such stimulation are suggested by both neurological studies which show a large amount of degeneration in the cells of the olfactory bulb and studies of perception which indicate that adults with Alzheimer's disease and related dementias perform poorly on tests of smell identification and detection. Current approaches to using olfactory stimulation as a component of interventions for adults with age-related dementia may need to be either abandoned or reassessed.
