This is the second revision of an application (1 R01 NS056397), "Epidemiologic Study of Brain Vitamin E, Diet and Age-Related Neurologic Diseases", which was not funded. This application proposes to use data from an existing longitudinal clinical-pathologic study, the Religious Orders study, to analyze biochemical levels of the various forms of vitamin E in post-mortem brain tissue and cerebrospinal fluid in 450 deceased participants as well as selected markers of neuropathology and neural reserve, oxidation, inflammation, and insulin activity, and to collect prospectively annual dietary exposure data on the entire cohort of 800 participants. The Religious Orders Study will provide at no cost to the proposed study, data on all non-dietary risk factors, all clinical outcome data on neurological diseases and cognitive and motor function, and most data on post-mortem neuropathology of brain tissue. Recent studies by this group and others suggest that high-dose a-tocopherol, which is currently being tested in clinical trials, may not be the effective therapeutic agent. If funded, the proposed study will have the unprecedented ability to relate brain levels of the various forms of vitamin E to clinical- pathologic outcomes relevant to Alzheimer's disease (AD) and parkinsonian signs as well as to dietary exposures. The proposed multidisciplinary team conducted a pilot study that suggests brain levels of both gamma and alpha tocopherols are inversely related with AD neuropathology and severity of parkinsonian signs, and positively associated with semantic memory. Substantiation of these associations in the entire cohort would be of the utmost importance to the public health, especially given the debilitating and incurable nature of these diseases, and their high occurrence among the fastest growing age group in the US population. Principal Investigator/Program Director (Last, First, Middle): Morris, Martha Clare This is the second revised R01 application to investigate the relations of tocopherols in the brain to age-related neurological diseases and to dietary tocopherols in an existing longitudinal clinical -pathologic study, the Religious Orders Study.

这是申请(1 R01 NS056397)的第二次修订，“大脑维生素E、饮食和年龄相关神经疾病的流行病学研究”， 它没有得到资金支持。这项申请建议使用现有的纵向临床-病理研究，宗教教团研究， 450例死亡者死后脑组织和脑脊液中各种形态维生素E生化水平分析 以及选定的神经病理和神经储备、氧化、炎症和胰岛素活性的标志物，并前瞻性地收集 整个800名参与者队列的年度饮食暴露数据。宗教秩序研究将免费提供给拟议的研究， 关于所有非饮食风险因素的数据，关于神经系统疾病以及认知和运动功能的所有临床结果数据，以及关于 脑组织的死后神经病理学。该小组和其他人最近的研究表明，高剂量的α-生育酚，目前 在临床试验中，可能不是有效的治疗剂。如果得到资助，这项拟议的研究将具有前所未有的能力 将大脑中各种形式的维生素E水平与阿尔茨海默病(AD)和帕金森氏症相关的临床病理结果联系起来 体征以及饮食暴露的影响。拟议的多学科团队进行了一项初步研究，表明大脑伽马和 α-生育酚与阿尔茨海默病的神经病理和帕金森症状的严重程度呈负相关，与语义记忆呈正相关。 在整个队列中证实这些关联对公共健康至关重要，特别是考虑到 这些疾病的衰弱和无法治愈的性质，以及它们在美国人口中增长最快的年龄段中的高发率。 首席调查员/项目主任(最后、第一、中间)：莫里斯、玛莎·克莱尔这是第二次修订R01申请进行调查 既往纵向临床研究中脑内生育酚与年龄相关神经疾病和饮食生育酚的关系 -病理学研究，宗教教团研究。
