 This study was conducted to determine if the loss of functional ability in geriatric patients occurs in the reverse order of child development along with loss of cognitive function, and if so, what is the relationship between functional age and Hasegawa's Mental Screening Examination(HDS)scores. Also can the HDS be used not only as a mental screening test but also as a clinical tool to transfer medical diagnostic information into direct patient care? For this purpose, all of the 131 residents of a special care geriatric home were evaluated for this study. Functional skill level was determined by using the check list devised by the authors with 13 items taken from child development of 3 months to about 12 years of age. Many patients who have motor impairments showed lower scores in the items which need motor ability but could perform higher items requiring less motor skill. The analysis of HDS and functional skill data was done by using Pearson's product moment correlation coefficient, Spearman's nonparametric correlation coefficient, and a regression equation.

 The results showed that there is a good correlation between HDS scores and functional skill level. As hypothesized, the loss of functional ability occurred in the reverse order of child development. Also there is a good correlation with functional age level, thus making it possible to estimate functional age level. Clinically, the HDS scores can be used as good clinical tool to transfer medical information into direct patient care.
