Elderly (aged 60+): living at home, independent, no memory complaints. NORMA (aged 18+) with identified disease, carriers of mutated gene associated with familial early-onset AD, normal performance according to age and education level in all diagnostic battery tests. Patients from memory assessment centres: SCI (aged 50+), no memory complaints, normal performance according to age and education level in all diagnostic battery tests. MCI meeting current amnestic MCI criteria with memory complaints, objective episodic memory deficits, performances in other cognitive functions where memory loss could occur, standard performance for age and education level in assessments of overall cognitive ability, independent in everyday life, no dementia according to DSM-IV criteria and no probable AD according to NINCDS-ADRDA criteria. Alzheimer's patients meeting NINCDS-ADRDA criteria for probable AD with abnormal overall cognitive function and deficits in at least 2 cognitive areas identified by diagnostic battery tests; mild- to moderate-stage AD; accompanying party's signed informed consent. SAND: CHU neurology departments - major episodic memory disorder that may be related to an objective deficit in executive function and standard performance for age and education level in all diagnostic battery tests measuring instrumental function.",

    ['A diagnostic commission is organised on a monthly basis to report subject/patient neuropsychological results, as well as their enrolment category, on a case-by-case basis. A multimodal meeting is organised on a monthly basis to report quality control results for imaging data. This trial is monitored by a person appointed by the CHU to ensure that exact, complete and reliable data is collected and to provide logistical support to research centres.']
