We have studied neuropathologically 200 aged nursing home residents (101 men and 99 women) autopsied between 1976 and 1985. Seventy-three of the 200 showed dementia during life, that is, 27% and 55% of the residents in nursing homes and special nursing homes, respectively. The relative frequencies of SDAT and VD in nursing homes as a whole were the same (34%). The relative frequencies of SDAT and VD in special nursing homes, where usually high concentrations of VD have been noted, were 21% and 52%, respectively. A comparison of the results of our special nursing homes (SDAT:VD = 1:2.5) and nursing homes as a whole (SDAT:VD = 1:1) with those of Barnes and Raskind (SDAT:VD = 2:1) and Rovner et al. (SDAT:VD = 3:1) showed that the frequencies of VD in Japanese nursing homes are considerably higher than those in their American counterparts.
我们对1976年至1985年间接受尸检的200名老年疗养院居民（101名男性和99名女性）进行了神经病理学研究。200名居民中有73人在生前患有痴呆症，即在疗养院和特殊护理院的居民中分别占27%和55%。整个疗养院中SDAT（阿尔茨海默病性痴呆）和VD（血管性痴呆）的相对频率相同（34%）。在通常注意到VD（血管性痴呆）高发病率的特殊护理院中，SDAT（阿尔茨海默病性痴呆）和VD（血管性痴呆）的相对频率分别为21%和52%。将我们特殊护理院（SDAT:VD = 1:2.5）和整个疗养院（SDAT:VD = 1:1）的结果与Barnes和Raskind（SDAT:VD = 2:1）以及Rovner等人（SDAT:VD = 3:1）的结果进行比较，发现日本疗养院中VD（血管性痴呆）的发病率明显高于美国疗养院。
