[Clinical application of Japan Stroke Scale Higher Cortical Function (JSS-H)]

To clarify the characteristics of Japan Stroke Scale Higher Cortical Function (JSS-H), we compared the results of JSS-H with those of Revised Hasegawa Dementia Scale (HDS-R), on the 47 patients with cerebrovascular disease visiting to the day-care center of the Yoshinaga Municipal Hospital. The scores of the two scales significantly correlated. Especially, among the patients who gained over 21 points (non-dementia) in HDS-R, the results of both scales were almost parallel, but among those who gained less than 20 points(dementia), the scores showed some discrepancy. Most of the patient with discrepancy had higher scores in JSS-H than in HDS-R, and were independent in their daily life despite of their memory disturbance. These results suggest that JSS-H can assess more global cerebral function than HDS-R and will be useful for estimating the characteristics of the higher cortical function of the patients, although it has some problems to be solved for clinical application.
