Abstract


Background:Cognitive impairment is an important clinical issue among elderly patients with depression and has a more complex etiology. The aim of the present work was to examine the prevalence of cognitive impairment and depression in elderly subjects above 60 years.

Methods: A cross-sectional study on the prevalence of cognitive impairment and depression on elderly people (n=525) attending the General Medicine OPD of Sri Venkateswara Ram Narain Ruia Government General Hospital, Tirupati. Cognitive function and depression were assessed by applying standardized Mini-Mental State Examination of Folstein (MMSE) and the Geriatric Depression Scale (GDS), respectively.

Results:Prevalence of cognitive impairment was 31.0% (34.7% women, 23.4% men); there were significant differences observed with reference to age, gender, literacy and economic status. Prevalence of depression was 44.8% (51.0% women, 39.6% men); with relation to age, gender, literacy and economic status, there were significant differences observed.

Conclusion:Cognitive impairment and depression were present in elderly people and these disorders are more prevalent in the females than in the males. Hence, psychiatrist should pay special attention for early detection and treatment of depressive symptoms in elderly people with cognitive impairment.
