Residents in good health will be invited to participate in the treatment arms of the study if they also comply with the following criteria. They must:
1. Have been living in the nursing home for more than 3 months
2. Be more than 65 years old

4. Have English as their first language
They must also have:
5. A Mini-Mental State Examination (MMSE) score of 10-26
6. A diagnosis of dementia, short-term memory loss or cognitive impairment that is not caused by any other diagnosis of mental illness
7. Residents with non-acute concomitant diseases may participate if their disease is medically controlled.

- Primary Outcome Measures
Name Time Method The primary outcome measure will be the difference in mean baseline and endpoint scores on the standardised Mini-Mental State Examination (MMSE) (Molloy et al., 1991). The MMSE is the standard scale used by aged care facilities for assessing the stage of dementia and cognitive function of their residents.<br><br>The annual rate of change on the MMSE for people with a base-line score between 7-28 is a decrease of 3.6 points per year, or about 0.9 points per 12 weeks (Swanwick et al., 1998). A typical Alzheimer's drug trial reports a mean MMSE increase over 12 weeks between 0.8 and 2.3 points for a similar population.
- Secondary Outcome Measures
Name Time Method Secondary outcome measures will be:<br>1. Difference in baseline, repeated measures and endpoint scores on the Nurses? Observation Scale for Geriatric Patients (NOSGER) (Spiegel et al. 1991)<br>2. Changes in the use of other medications related to cognitive and behavioural functions (for example, anti-depressants, anti-psychotics)<br>3. Correlation between ability to smell the treatments and end-point scores on MMSE and NOSGER
