Abstract


OBJECTIVE
This study aimed to investigate the neurocognitive functions of patients with late-life depression compared to healthy controls and their association with improvement of depressive symptoms.
METHODS
We compared the results of neurocognitive tests between 41 patients with late-life depression and 20 healthy controls at baseline and 3 months later prospectively. And then we investigated the association of change of cognitive function and improvement of depressive symptoms in patients with late-life depression.
RESULTS
Patients with late-life depression showed significantly impaired results in neurocognitive tests especially in domains of language, memory and frontal executive function compared to healthy control. However, after 3 months of treatment of depression, there was no association between the change of results of neurocognitive tests and the changes of scores of Hamilton Depression Rating Scale (HAM-D).
CONCLUSION
Impairment of cognitive functions in late-life depression includes the domains of language, memory and executive function and after 3 months of treatment of depression, there was no association of improvement of depressive symptom and cognitive change in patients with late-life depression.
