Intervention model: CROSSOVER
Primary purpose: TREATMENT

Brief summary: The early assessment of new drugs for Alzheimer's disease remains difficult because of the lack of predictive end-point. The use of a battery including different parameters could improve this early development of new drugs. Nevertheless, the interest of such a battery should previously be validated with the yet marketed AD drugs.

Detailed description: The aim of the present study is to test the effect of a 15-day treatment with memantine on a mixed battery associating cognitive assessment, imaging and neurophysiological tests in healthy volunteers.

This multicenter, randomized, placebo-controlled, cross-over study is double-blind controlled and is conducted in 3 centers located in France (Lille, Marseille and Toulouse).

18-30 years old, healthy volunteers, without any neurological or psychiatric impairment, will complete 2 test sessions in a randomized order: one with a 15-day treatment with memantine, the other with placebo, and will be submitted to a mixed battery during the 14th and 15th day of the treatment. The primary outcome of the study will be based on cognitive assessment, imaging parameters and neurophysiological parameters

Eligibility criteria: Inclusion Criteria:

* 18-30 year old male non-smoker subjects

* Subject without history or current mental disease or addiction (MINI)
* Subject without lesion on MRI
* Subject without abnormal electrical activities on EEG

Exclusion Criteria:

* Subject with dementia or cognitive decline identified by Moca \< 26
