Through this web site, qualified scientists may obtain access to imaging (MRI and PET), clinical and biomarker data obtained as part of the ADNI project. The ADNI is a multisite, multiyear program which began in October 2004. Patient enrollment began in late Summer of 2005, and is expected to continue until the Fall of 2007. Approximately 800 subjects will be recruited, 200 elderly controls, 400 with mild cognitive impairment and 200 with Alzheimer's disease. Subjects will be followed for 2-3 years and will be seen approximately every 6 months. All data are de-identified to protect patient privacy.
Prospective investigators must submit an on-line application to request access to the ADNI data. As part of the application process, investigators are required to provide information about proposed research plans and agree to the ADNI data sharing and publication policies. Applications are reviewed by the Data Publication and Sharing Committee within one week of receipt.
