Text: Data used in the preparation of this article were obtained from the Alzheimer<U+0092>s Disease Neuroimaging Initiative (ADNI) database (adni.loni.usc.edu). The ADNI was launched in 2003 as a public-private partnership. The primary goal of ADNI has been to test whether serial magnetic resonance imaging (MRI), positron emission tomography (PET), other biological markers, and clinical and neuropsychological assessment can be combined to measure the progression of MCI and early AD. This research was approved by the Institutional Review Boards of all participating sites, and written informed consent was obtained for all study participants.   http://adni.loni.usc.edu/<|eot_id|><|start_header_id|>assistant<|end_header_id|>
