• Patient with major physical or neurosensory problems likely to interfere with the tests; contraindication or refusal to perform functional brain imaging examinations;
• Absence of caregivers to complete psychological and behavioral scales and/or questionnaires;
• Patient with illiteracy and/or inability to perform psychological and behavioral evaluations;

• Pregnancy or breast-feeding;
• Vitamin B12 or folic acid deficiency without supplementation;
• Patient living in institution;
• Patient deprived of liberty by law;

• Male and female patients between 50 and 90 years inclusive;
• Sufficient clinical and paraclinical information for the diagnosis of AD according to the international diagnosis criteria from McKhann G. M. et al. 2011;
• Patient presents clinically significant behavioral and psychological symptoms of dementia (BPSD) requiring medication in the opinion of the study physician (at least one item of the Neuropsychiatric Inventory-12 \[NPI-12\] with a score ≥ 4);
• Mild to-severe AD with a Minimal Mental State Examination (MMSE) score from 10 to 26 included;
• Symptomatic treatments of AD (acetylcholinesterase inhibitors and memantine) and psychotics drugs (benzodiazepines, antidepressants, anxiolytics, neuroleptics) are allowed but need to be maintained during at least 4 weeks before inclusion and during the follow-up;
• Female patient of childbearing potential must be willing to use an efficient birth control method during the study and until 5 days after the end of the treatment.
  • A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus, tubal ligation).

• Male patient must be willing to use male contraception (condom) during the study;

• Patient affiliated to French social security;
• Patient is willing to and can comply with the study protocol requirements, in the opinion of the investigator.
• If the patient took part to another therapeutic clinical trial, he/she must systematically observe a wash-out period of \> 4 weeks, or of \> 6 months if he/she received a biologic disease modifying treatment (antibodies targeting the β-amyloid protein or the p-Tau protein) or 5 half-lives of investigational drug(s), whichever is longer.
