Alzheimer's disease

Abstract
We carried out a correlational analysis of the scores on the Blessed Information-Memory-Concentration Test and the Mini-Mental State Exam in 40 subjects with Alzheimer''s disease. The average product moment correlation coefficient between the two tests on repeated administration over 6 weeks ranged from -0.73 to -0.83. Both tests demonstrated test-retest reliability coefficients of 0.75 and above. A formula was developed to convert one test score to the other.
