What this trial is about
Study to understand factors related with the preclinical stages of Alzheimer's Disease and investigate markers that predict its progression. Cross-sectional and single arm study performed on a subgroup of individuals recruited in the ALFA project. Study without therapeutic interest for the research participants (440 participants of the ALFA project who have been selected for being cognitively healthy and in their vast majority are direct descendants of patients diagnosed with Alzheimer's Disease). Each study candidate will be selected from the ALFA project (STUDY 45-65 FPM/2012) according to their clinical characteristics, their compliance to selection criteria and their desire to participate in this study. After signing this study's specific informed consent form, the neuropsychological screening and the brain MRI acquisition will be performed. Once all inclusion criteria are checked, the PET scans with 18F-Flutemetamol and 18F-FDG will be performed
