PI PROTOCOL

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 这是一个仪器协议，其中测试了各种新型仪器在阿尔茨海默病一级预防试验中的未来效用。 同时，测试管理的三种方法正在测试：在诊所，在家里，和基于网络的方法。 本试验已全部入组，共有31例受试者参与试验，将跨越未来4年进行纵向数据收集。 由于研究已停止入组，因此未随附知情同意书文件。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This is an instrument protocol in which various novel instruments are tested for their future utility in primary prevention trials for Alzheimer's disease. Simultaneously, three methods of test administration are being tested: in clinic, at home, and web-based methods. This trial is fully enrolled, with 31 subjects involved in the trial, which will span the next four years for longitudinal data collection. No consent form document is enclosed since the study is closed to enrollment.
