The purpose of this study was to explore the effectiveness in how the group art therapy centered on
repetition expression affects their picture expression and linguistic expression of hemiplegia elderly patients
with dementia. This study was a case study observing and recording a sequence of art therapy processes
on the subjects of elderly patients residing in a sanatorium for 43 sessions in total, a session per week
between February 2012 and December 30, 2012. Following are the results of this study: It was found that
there was a positive effect of the group art therapy centered on repetition expression upon the picture
expression and linguistic expression of hemiplegia elderly patients with dementia. The group art therapy
applying repetition expression not only increased perception and understanding of the objects but played a
role of catalyzer which induced formative elements and recollection as well, and it was confirmed that it
could be a way of constituting something that hemiplegia elderly patients with dementia might have which
otherwise might be collapsed.
