Hasegawa Dementia Scales: What’s in a Name?
Masatoshi Takeda
Hasegawa Dementia Scale Revised (HDS-R)
was invented in Japan. Now its revised version is
the most popular screening test for dementia in
Japan. In this issue of the Taiwanese Journal of
Psychiatry, I am pleased to read the paper “The
Revised Hasegawa’s Dementia Scale (HDS-R) as
a Screening Tool for Delirium” [1], in which Chen
and her associates successfully expanded the use
of HDS-R. Inspired by the paper, I accepted
Winston W. Shen’s invitation to write a compan-ion editorial specifically to explain the initial and
revised development of HDS during the time
when psychogeriatric research began in Japan.
