H. Allen et al., DEPRESSION IN DEMENTIA - A STUDY OF MOOD IN A COMMUNITY SAMPLE AND REFERRALS TO A COMMUNITY-SERVICE, International journal of geriatric psychiatry, 12(5), 1997, pp. 513-518
The association between degree of cognitive impairment and severity of
depressive symptoms was examined in a randomly selected community-bas
ed sample of elderly people and in a sample of patients referred to an
old age psychiatry service. Findings contradict previous reports of l
ess cognitive impairment in demented patients with depressive symptoms
. We suggest that sample selection bias has contributed to the earlier
reports. (C) 1997 by John Wiley & Sons, Ltd.
