Objective: To examine the associations of depression in the carers of
dementia sufferers, diagnosed on the basis of a semistructured intervi
ew. Design: Case control study. Setting: Referrals to clinical service
s. Subjects: The informal carers of 109 dementia sufferers, 32 with de
pression and 77 without. Measures: Carers were interviewed using the G
eriatric Mental State Schedule. The diagnosis of depression was made a
ccording to Research Diagnostic Criteria. Instruments used to assess a
ssociations included Carers' Stress Scale, Marital Intimacy Scale, Cor
nell Depression Scale and CAMCOG Schedule. Results: Only increasing ag
e was significantly associated with depression in the overall group of
carers. The severity of cognitive impairment was significantly associ
ated with depression in carers who lived with a dementia sufferer and
a low level of premorbid marital intimacy was significantly associated
with depression amongst carers who were marital partners. Conclusion:
Few factors are clearly associated with depression in the carers of d
ementia sufferers. The pattern of associations was, however, different
for carers in different situations.
