Evaluation of the usefulness of a simple touch-panel method for the screening of dementia.

In clinical settings, Hasegawa's dementia scale, revised (HDS-R), and the mini-mental state examination (MMSE) are widely employed as simple mental function tests useful for the diagnosis of dementia. In recent years, for the early diagnosis of dementia, a simple computerized touch panel-type screening test (touch panel-type screening test), called the "forgetfulness consultation program" (Nihon Kohden Corp.), has been developed. We performed dementia screening using this touch panel-type screening test in 95 elderly subjects, and evaluated its usefulness in comparison with HDS-R or MMSE. The results of evaluation using the touch panel-type screening test were significantly correlated with those using HDS-R and MMSE in the elderly subjects. This touch panel-type screening test was not time-consuming (about 3 min) since it includes only a small number of test items. It could also be performed solely by the examinee, and so was free from examiner-related bias. Therefore, this method may be very useful for the diagnosis of dementia and evaluation of its severity.
