Description

The purpose of this study was to evaluate the effect of keishibukuryogan (KB) against the cognitive symptoms associated with silent brain infarction in a prospective cohort study. The subjects were 93 patients with silent brain infarcts who visited the Department of Japanese Oriental Medicine, University of Toyama, and its allied hospitals. They consisted of 24 males and 69 females, mean age (± S.E.) 70.0±0.8.Group SK (n=51) consisted of patients who used KB extract for more than6months per year. Group SC (n=42) consisted of patients who did not use Kampo formulas. The NS group (n=44) consisted of elderly subjects who had no silent brain infarction, 21 males and 23 females, with a mean age (± S.E.) of 70.7±0.7 years. Among the three groups, the revised version of Hasegawa's dementia scale, apathy scale and self-rating depression scale were compared between the study start and after three years. In the SK and SC groups, these scores, and the subjective symptom levels (head heaviness, headache, dizziness or vertigo, stiff shoulder) were also studied. The results showed that the self-rating depression scales at study start for the SK and SC groups were significantly higher compared to the NS group. In spite of the scores for the NS group increasing after three years, the SK group scores were significantly decreased compared to the SC and NS groups. KB was effective against head heaviness, which often complicates silent brain infarction. In the above mentioned, KB was effective in treating cognitive disorders and subjective symptoms related to silent brain infarction.
