NCT02839187

Brief Summary

The present study aimed at measuring cerebral changes in Alzheimer Disease (AD) patients, who responded to strict physiological criteria typical of AD pathology. The objective of the present study was to identify the earliest alterations in cerebral connections that could contribute to the initial episodic memory impairment.

Outcome Measures

Primary Outcomes (1)

  • fixing the AV-45 during PET

    compare fixing the AV-45 during a examination emission tomography (PET) between three different groups: healthy subjects, patients with Alzheimer's disease and a mild stage patients of Alzheimer's disease at a pre-dementia stage

    baseline

Secondary Outcomes (3)

  • Deposition of amyloid protein

    baseline

  • Standard Cognitive function

    Baseline

  • Specific memory evaluation

You may qualify if:

  • For all subjects :
  • Capacities visual, auditory (authorized devices) and oral or written expression sufficient for the proper performance of tests
  • Obtain informed written consent of the subject
  • Patients with AD :
  • Outpatient accompanied by a "helping"
  • No parenchymal lesions allowing isolation explain the symptoms on brain MRI (T1 and T2) carried more than 6 months prior to enrollment in the study. Patients with more than three hyperintense white matter or visible lacunar infarction or T2 FLAIR will not be included in the study.
  • probable Alzheimer's disease diagnosis par with international standards
  • Illness in a mild stage (CDR 1, 24 ≥ Mini-Mental State Examination (MMSE)\> 18)

  • Alzheimer's Diagnosis pre-dementia based on the search criteria
  • Illness in a mild stage (CDR 0.5, 30 ≥ MMSE ≥ 25)
  • ADL items ≤ 4 1/4
  • Control subjects :
  • ≥ MMSE ≥ 27
  • +4 more criteria

You may not qualify if:

  • Subjects with a contra-indication to MRI (carrying a pacemaker or cardiac defibrillator, implanted a material activated by an electrical, magnetic or mechanical carriers hemostatic clips intracerebral aneurysms or carotid artery , holders of orthopedic implants, claustrophobia)
  • Subjects with clinically significant gastrointestinal, renal, hepatic, endocrine, or cardiovascular
  • Subjects with a psychiatric disorder or progressive neurological
  • French Language level insufficient to be appropriately involved in neurophysiological evaluation
  • less than 5 years Education (insufficient understanding level to participate in the study)
  • Administrative problems: unable to give informed about information, not covered by a social security system
  • Hypersensitivity to the active substance or to any of the excipients
  • unbalanced diabetes mellitus
