Design
Blinded comparison of HVLT and MMSE results with Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition (DSM-IV) diagnoses of dementia (the diagnostic standard).
Setting

56 patients (mean age 75 y, 63% women, mean education 8.5 y) participated. Exclusion criteria were age <65 years, hearing impairment, aphasia, MMSE score <18, insufficient ability to speak English, or inability to consent.
Description of tests and diagnostic standard
3 experienced registered nurses blinded to patients' diagnostic status administered the HVLT and the MMSE. The maximum HVLT total score was 36 and for the HVLT recognition score, 12. The maximum MMSE total score was 30. Each patient was assessed by an independent psychiatrist (blinded to HVLT and MMSE test results) for the presence of dementia and other psychiatric diagnoses using DSM-IV criteria.
