Rating reliability for life events and difficulties in the elderly

Life events and senile dementia. Affective symptoms

BACKGROUND

Previous research in the elderly has linked threatening life events with depression. Dementia sufferers are known to be sensitive to stressful changes in their daily life such as relocation. This study investigates whether threatening life events are associated with depressive symptoms in dementia sufferers.

METHOD

Using the Life Events and Difficulties Schedule, this study examined life events before admission in a group of 70 dementia patients compared with two control groups: dementia sufferers in the community and mentally fit elderly people matched for age and sex.

RESULTS

Life events with severe threat were not significantly more frequent in the dementia patients than in two control groups. However, depressive symptoms in the dementia sufferers were significantly associated with independent severe life events. This strong association was maintained when a multivariate analysis was used to control for the effects of other social factors and severity of cognitive impairment. This association appears to be specific to the threat aspect of life events since there was no association between depressive symptoms and events relating to change in the social environment.

CONCLUSION

In dementia sufferers, threatening life events are associated with depressive symptoms. This means that dementia sufferers are responsive to stress in the same way as cognitively intact individuals, and clinicians need to be more aware of the social influences on them.

Life events and senile dementia. I. Admission, deterioration and social environment change

This study examines the frequency of life events before admission and before deterioration in 70 dementia patients, in comparison with 50 dementia controls living in the community and 50 fit elderly people matched for age and sex. We hypothesized that there would be an excess of events connoting changes in routine and the social environment. Specific scales were developed to measure these aspects of events. Our results supported the initial hypothesis, confirming that it is the social disruptiveness of change rather than the threat implied by life events that is associated with deterioration. The findings are discussed in the light of current models of the dementia process.

Life events, life difficulties and confiding relationships in the depressed elderly

A total of 101 elderly depressed patients and 85 community residents (matched for age and sex) were interviewed about life events, difficulties, and confiding relationships. Significantly more of the depressed sample reported at least one severe event in the three months before the onset of their illness. Lack of a good confiding relationship was associated with depression in men but not in women. In this relatively affluent Australian sample, life difficulties were rare and, probably as a result, were not significantly associated with depression.
