Objective:To study cognitive function and activities of daily living (ADL) in patients with remitted geriatric depression (RGD) and to determine their relationship. Methods:Fifty-one patients with GRD and 52 normal control subjects were recruited. Their cognitive function and ADL were mainly examined by Mattis dementia rating scale (MDRS) and ADL scale. Results:Compared with control subjects,patients with RGD showed poorer cognitive function,which was not associated with Hamilton depression rating scale for depression (HAMD) scores and antidepressant treatment. ADL score of RGD patients was significantly lower than that of normal control subjects. The score of initiation/perseveration subscales of MDRS was significantly negative correlated with ADL scores. Conclusion:Cognitive impairments might be persisted as endogenous damages of RGD,which may affect ADL.
