EPIDEMIOLOGICAL STUDIES ON BRAIN AGING IN JAPAN AND THE UNITED STATES

Ni-Hon-Sea-Tai项目是一个协调的流行病学研究系列， 关于痴呆症的研究，其中包括在成人健康研究队列中进行的一项调查， 广岛的辐射效应研究基金会。 该项目 由亚太办事处组织，并继续作为一项共同努力， 在西雅图、川崎市、台北、广岛和 檀香山。 一个中心目标是开发和使用足够相似的方法 这样就可以比较不同地区痴呆症的发病率和发病模式， 网站将是可能的。 与广岛研究的协调是通过建立 与能源部的机构间协议，通过该协议， 向RERF提供了与我们的合作有关的工作 关于痴呆症的研究 这些资金的很大一部分用于支持 日本科学家参加第六次日美 跨国痴呆症研究方法。 该项目进展顺利，很可能平行研究 使用可比的方法将在美国的两个地点进行， 日本的一个或两个研究中心，以及台湾的至少两个研究中心。

The Ni-Hon-Sea-Tai project is a coordinated series of epidemiologic studies on dementia that include a survey in the Adult Health Study Cohort of the Radiation Effects Research Foundation (RERF) in Hiroshima. The project was organized by the Asia-Pacific Office and is continued as a shared effort by cooperating scientists in Seattle, Kawasaki City, Taipei, Hiroshima, and Honolulu. A central goal is to develop and use methods sufficiently alike so that comparisons of rates and patterns of dementing illnesses across sites would be possible. Coordination with the Hiroshima study was facilitated by establishment of an interagency agreement with the Department of Energy, through which funds were made available to the RERF for work related to our collaborative studies on dementia. A large part of these funds were used to support the participation of Japanese scientists in the Sixth Japan-U.S. Workshop on Methods for Cross-National Dementia Research. The project is progressing well and it is likely that parallel studies using comparable methodologies will be conducted at two sites in the U.S., one or two sites in Japan, and at least two sites in Taiwan.
