Background: There are many comprehensive neuropsychological tests to assess Alzheimer’s disease in mild to moderate stage. In contrast, there have been few rating scales for neuropsychological evaluation of the severe Alzheimer’s disease patients.
Methods: We developed the Severe Dementia Rating Scale (SDS), that evaluates cognitive functions using 30 questions that assess orientation, memory registration, calculation, attention, memory recall, visuospatial and verbal functions, and motor function. Ninety seven probable and possible AD patients received the Clinical Dementia Rating Scale (CDR), Korean version of Mini-Mental State Examination (K-MMSE), Severe Dementia Rating Scale (SDS) and some also received Barthel Activity of Daily Living Index (B-ADL). We tested internal consistency, test-retest reliability and validity.
Results: The SDS significant by correlated with CDR -0.85 (p<0.01), B-ADL -0.51 (p<0.01), and K-MMSE 0.79 (p<0.01). Internal consistency was -0.86 and test-retest correlation was 0.97.
Conclusion: The SDS can be a brief and easy test for staging patients with moderate to severe dementia with excellent reliability and validity.
