This study describes two well-characterized groups of Alzheimer's disease (AD) patients with similar levels of cognitive functioning, but with different overall behavioural disturbance levels. Seeks to determine the nature of this difference - whether AD patients with higher levels of behavioural disturbance differ from less disturbed AD patients in terms of the range of symptoms exhibited; the frequency of occurrence of these symptoms; or both of these. Results found that differences occurred in the frequency of 10 out of 21 behaviours, rather than in a variety of endorsed behaviours. These 10 behaviours, observed at different frequencies in both groups, may be useful for monitoring change in studies of drugs or behavioural interventions for behavioural disturbance in persons with AD.
