Objectives
Narrative objectives1 To optimize the criteria for evaluation of treatments for Alzheimer's disease (AD), determination of surrogate biomarkers that reflect the pathophysiology of AD is mandatory. J-ADNI study aims at setting the standard values for long-term changes in imaging surrogate markers (e.g., MRI and PET), and simultaneously collecting clinical/neuropsychological data as well as blood/cerebrospinal fluid samples, to eventually prove the adequacy of the surrogate endpoints.
Basic objectives2 Others
Basic objectives -Others Establishment of imaging and biochemical surrogate markers that reflect the progression of Alzheimer's disease.

Assessment
Primary outcomes Clinical/neuropsychological examinations: CDR, MMSEm WMS-R logical memory I & II, ADAS-Cog, clock drawing/copying, symbol, block design, digit span, knowledge, fluency, trail making test A & B, Boston naming test, geriatric depression scale, Neuropsychiatric Inventory Q, FUnctional activity questionnaire
Magnetic Resonance Imaging of brain: 1.5 tesla MRI in all cases, 3 tesla in 25% of cases
Positron Emission Tomogram: fluorodeoxy glucose PET in 50% of cases
Lumbar puncture: in 50% cases at baseline and 12 months
blood and urine collection in all cases
amyloid PET imaging (25% cases)
