Behavioural disturbances in dementia.
OBJECTIVE
To assess the frequency of behavioural disturbances in patients suffering from dementia and their relation to dementia severity.


METHODS
The study evaluated 75 patients referred to the Memory Clinic at our hospital. Patients meeting DSM-IV criteria for dementia were included in the study. Activities of daily living (ADL) and cognitive functioning were also assessed. Patients were then rated for dementia severity using the Clinical Dementia Rating scale. Clinical data regarding behavioural disturbances was obtained from the patient (where possible) and an informant (usually the primary caregiver) who had contact with the patient at least thrice a week.


RESULTS
Results showed that behavioural disturbances were present in more than 60% of the sample. Psychotic and activity associated disturbances were most common, and that these were seen more frequently in Alzheimer's disease than any other type of dementia. Further, these disturbances occurred most frequently in dementias of moderate severity but reduced as the dementia progressed further.


CONCLUSIONS
Our results indicate that behavioural disturbances are a prominent part of dementia and that judicious use of psychiatric medication should form an important aspect of management.
