Alzheimer's Disease
Conditions
Brief summary
Investigators propose in this study to evaluate prospective memory (MP) in all its complexity as well as the processes, cognitive and brain, the underlying. Specifically, investigators propose to evaluate the evolution of the MP during normal aging and Alzheimer's disease (AD) to identify the cognitive and brain processes underlying this development. To do this, this study will have to include healthy subjects, 18 to 95 years, patients with Mild Cognitive Impairment (MCI) and patients with probable AD. All participants will undergo a series of examinations, both neuropsychological and brain imaging.

Inclusion criteria
* All participants: * Normal Education\> 7 years * French mother tongue * right-handed (Edinburgh Inventory) * score on the scale of Beck \<7 (depression scale) * signing the informed consent of the protocol in agreement with the Committee to Protect People * Medical examinations, neurological, neuropsychological and neuroimaging depth in accordance with the specific inclusion and
Exclusion criteria
for each population, that is to say: * Young healthy subjects aged between 18 and 44 years * Healthy subjects intermediate age: between 45 and 69 years * score on the Mattis Dementia Scale higher than 137, in order to exclude any potential dementia * Performance normal to test RI RL-16 (that is to say, not differing by more than 1.65 standard deviation from the norm for age and cultural level \[see normative values published Van der Linden et al., 2004\]), test conventionally used to assess the verbal episodic memory. * Healthy elderly subjects aged 70 and over, living at home * score on the Mattis Dementia Scale higher than 137, in order to exclude any potential dementia * Performance normal to test RI RL-16 (that is to say, not differing by more than 1.65 standard deviation from the norm for age and cultural level \[see normative values published Van der Linden et al., 2004\]), test conventionally used to assess the verbal episodic memory. * MCI patients: older than 50 years and recruited from memory clinics and meet the current criteria and recognized including amnestic MCI * memory complaint * targets deficits of episodic memory (lower performance of at least 1 standard deviation from the norm for age and cultural level to one or more (sub) episodic memory scores of diagnostic battery - cf. . Tables 1 and infra) * performance in the standards for age and cultural level in all tests of diagnostic battery measuring other cognitive functions as memory, including the evaluation of overall cognitive ability tests. * Alzheimer's patients: older than 50 years were recruited from the clinics and memory satisfying the standards NINCDS-ADRDA criteria for probable AD which include * abnormal global cognitive functioning and deficits in two or more cognitive domains identified by the diagnostic battery * mild to moderate AD (MMSE ≥ 18).
