It will be conducted in an outpatient setting at the tertiary memory clinics (CMRR) in France in patients with a preliminary diagnosis based on the completion of a prior, full diagnostic workup, not more than 12 months previously - which could include, but will not be limited to brain imaging if needed (magnetic resonance imaging (MRI) or computed tomography (CT)), neuropsychological evaluation including a Mini-Mental Status Examination (MMSE), CSF examination and other examinations according to "Haute Autorité de santé" (HAS, National Authority of Health, France) Recommendations - and in whom:

For all subjects the study will comprise 3 outpatient clinic visits to record information on previous work ups and to perform the FBB Positron Emission Tomography (PET) scan (Visit 1: screening/ baseline, Visit 2: PET scan, Visit 3: subject informed on the FBB PET scan result).
At Visit 1, the initial diagnosis based on previous work up will be collected and rated on a five-point Likert confidence scale by the Physician.
At Visit 2, the FBB PET scan will be performed. Adverse events will be reported during the exam and up to 7 days after the PET procedure.
At Visit 3, based on the amyloid PET scan results, change of diagnosis will be collected, in addition to physician confidence.
