Demographic and clinical profiles of patients with a Clinical Dementia Rating of 0 at baseline.

Analysis of variance with post-hoc Tukey’s test was used for group-wise comparisons of baseline scores and progression rates except for the UPDRS tremor/non-tremor scores. Two-way analysis of variance with post-hoc Tukey’s test was used for the UPDRS tremor/non-tremor scores. Data are given as the mean±SD except for the fields with asterisks. a and b indicate p*Data are given as (the number of patients below −1 SD)/(the number of patients who underwent the test).¶The scores were calculated according to Lewis and colleagues. [5] Data were obtained from 21 non-converters, 6 memory-only converters and 5 memory-plus converters.†The mean score for controls (n = 20, 65.5±4.8 years) is 21.3±3.5. [49].‡The mean score for controls (n = 24, 66.1±5.3 years) is 32.9±4.4. [32].§The mean score for controls (n = 20, 65.5±4.8 years) is 4.8±1.0.
