Comparison of Different Clinical Diagnostic Criteria for Depression in Alzheimer Disease

This study shows that there is a high variability in the prevalence rates of depression in AD depending on the diagnostic criteria used and that there is a low rate of agreement among the diagnostic criteria analyzed. The results suggest that the use of generic diagnostic criteria such as the ICD-10, the CAMDEX, or DSM-IV provides low prevalence rates of depression in patients with AD compared with specific diagnostic criteria such as the PDC-dAD.
