Objective: To develop a simple clock drawing score system for patients with Alzheimer's disease, that correlates with the MMSE (Folstein Mini Mental Status Examination).¹

Design: A retrospective analysis of 88 patients with the diagnosis of Alzheimer's disease

Setting: Outpatient Memory Disorder Institute of a large community teaching hospital.

Measurements: MMSE score and two different clock drawing ratings. The MMSE and the clock drawing scoring were performed by different raters. We present a "simple clock scoring system" and compared it with a previously published scoring system by Sunderland et al,² referred to as the standard score system.

Results: There is a strong correlation between the "new score system" and the standard scoring (Pearsons Correlation Coefficient r = 0.91, p < 0.001). However, when both systems were evaluated in a multivariate linear regression analysis, the " simple score system " was a significant predictor of Folstein MMSE (P < 0.01), while the standard scoring system was not.

Conclusion: The "simple score system" is an easy to use, accurate predictor of the MMSE score, in patients with the diagnosis of Alzheimer's disease.
