Study Stopped
On 15 January 2019, the sponsor decided to stop the study prematurely due to lack of patient recruitment because of supply problems with 18 F-Florbetaben.

Outcome Measures
Primary Outcomes (2)
Incidence of Adverse events of a single dose of FBB followed by PET scan in individuals at risk of genetic Alzheimer?s disease.
At baseline, when FBB-PET is performed.
Proportion of FAD mutation carriers that present positive uptake after FBB-PET through visual examination
At baseline, when FBB-PET is performed.
Secondary Outcomes (4)
Proportion of FAD mutation carriers presenting standardized uptake value ratios (SUVRs) of FBB-PET higher than 1,4.
baseline
Areas of significant difference (p<0,05) in regional SUVR between FAD mutation carriers and non-carriers.
baseline
Earliest age of positive FBB-PET in FAD mutation carriers.
baseline
Individual cortical areas with positive amyloid deposition at visual or semi-quantitative assessment

Eligibility Criteria
You may qualify if:
- Adult children (\> 18 yo) of genetic Alzheimer?s disease patients with a known mutation in PSEN1, APP o PSEN2 genes and who are either cognitively normal (CDR=0) or have mild symptoms of cognitive decline (CDR 0.5 or 1)
- According to the principal investigator, participants must be committed to participate and complete all study procedures.
- Has signed the Informed Consent Form voluntarily to participate in the study
You may not qualify if:
- Subjects that are not able to complete the study.
- Any major disease or history of a major disease, especially hepatobilliar disease (AST /ALT ? 5 x ULN) or advanced renal insufficiency (creatinine ? 2 x ULN)
- Current or previous history of alcohol abuse or epilepsy
- Allergic to Florbetaben or any of its constituents
- Multiple drug allergies and/or previous history of contrast allergy.
- Pregnancy or breast feeding or planned pregnancy during the study period
- Any disease or history of disease which, in the opinion of the investigator, can cause disturbance of brain function (e.g. vitamin B12 or folic acid deficiency, disturbed thyroid function)
- Evidence for any other neurological or psychiatric disease
