We investigated whether changes in these three instruments over time correlate with loss of cortical gray matter volume (cGMV). <b><i>Methods:</i></b> We retrospectively investigated 204 patients (aMCI, <i>n</i> = 114; AD, <i>n</i> = 90) who had undergone MMSE, CDR-SOB, the dementia version of the Seoul Neuropsychological Screening Battery (SNSB-D), and 3-dimensional T1-weighted magnetic resonance images at least twice. We investigated the partial correlation between annual decline in test scores and percent change of cGMV. <b><i>Results:</i></b> In aMCI patients, changes in the SNSB-D total score (<i>r</i> = 0.340, <i>p</i> < 0.001) and CDR-SOB (<i>r</i> = 0.222, <i>p</i> = 0.020), but not MMSE, showed a correlation with cGMV loss, with the SNSB-D total score showing the strongest correlation. In AD patients, decline in all three test scores correlated significantly with cGMV loss, with MMSE exhibiting the strongest correlation (<i>r</i> = 0.464, <i>p</i> < 0.001). <b><i>Conclusion:</i></b> In aMCI patients, neuropsychological battery, though time-consuming, was the most adequate tool in tracking disease progression. In AD patients, however, MMSE may be the most effective longitudinal monitoring tool when considering cost-effectiveness.</p> 2017-08-02 12:37:19 Alzheimer disease Mild cognitive impairment Mini-Mental State Examination Neuropsychological tests Longitudinal study Magnetic resonance imaging
