Subject characteristics between non-demented (n = 23) and demented (n = 24) subjects, as assessed by the GDS, were not statistically different, except that BMI in non-demented subjects was marginally higher than that in demented subjects [23.1 (3.5) vs. 21.0 (3.5) kg/m2, p = 0.067] (Table 1). Although higher proportion of subjects without dementia reported a history of alcohol use (p = 0.041), the data were only available for only 58% of demented participants.
