The ability of Improvement in the ability to perform the tasks was exhibited across the board for all patients with mild to severe dementia regardless of degree of cognitive impairment: two out of two patients with MMSE scores 0e9 improved (100%), 11 out of 13 patients with scores 10e19 improved (84.6%), and two out of two patients with scores 20e23 improved (100%). We found no significant correlation between the degree of improvement in forming the rice balls and degree of de- mentia (MMSE score) (Spearman’s rank correlation test showed, r Z e.07, p Z .82).
