Abstract

OBJECTIVE
The aims of this study were to investigate the prevalence of co-morbid depression and related factors of depression in mild cognitive impairment (MCI) patients.
METHODS
Nine hundred and six MCI individuals were included in this study. Depression was defined as major and minor depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). Depression-related demographic and clinical factors were also explored through multivariate logistic regression analysis.
RESULTS
In MCI patients, the prevalence of depression as defined according to the DSM-IV diagnostic criteria was 1.8% for major depressive disorder, 11.4% for minor depressive disorder, and overall 13.2% for both. Multivariate logistic regression showed that increased prevalence of overall depression was associated with female gender and non-amnestic subtype of MCI.
CONCLUSION
Our findings based on a large number of MCI subjects who visited memory clinic indicated that more than ten percent of MCI patients have comorbid depression. In addition, female and non-amnestic subtype of MCI patients seems to be more vulnerable to depression.
