Inclusion Criteria
  • Patients

    • Age between 40 and 85
    • French mother tongue
    • Consulting at the Amiens Memory Resource and Research Centre (CMRR) for:
    • MCI, according to Albert et al.'s criteria (Albert et al., 2011)
    • Mild dementia (MMSE>20) due to AD, according to McKhann's criteria (McKhann et al., 2011).
    • Mild dementia due to LBD, according to McKeith et al.'s criteria (McKeith et al., 2005).
    • Mild dementia due to FTLD, according to Rascovsky et al.'s criteria (Rascovsky et al., 2011).
    • Social security coverage
  • Healthy controls

    • Healthy age and gender matched volunteers will be recruited into the study from the general population.
Exclusion Criteria
  • Reading or writing difficulties related to a learning disorder or illiteracy.

  • A medical history with a potentially significant impact on cognition (non-corrected thyroid disorders or heart failure):

    • NYHA stage IV dyspnoea.
    • respiratory impairment requiring oxygen therapy.
    • liver impairment.
    • kidney failure, progressing neoplastic disease, or past or present alcohol abuse.
  • Past or present neurological disorders other than those having prompted consultation in the Memory Clinic:

    • stroke.
    • meningitis or encephalitis.
    • severe head injury.
    • sensorimotor impairments (sensory, proprioceptive, cerebellar and visual impairments).
    • epilepsy (requiring ongoing treatment),
    • psychiatric disorders (other than treated depression).
    • treatment with psychotropic medications (other than anxiolytics or antidepressant withdrawn or initiated in the previous month). Patients with parkinsonian syndrome were examined in the "on-drug" state.
  • Impossibility to perform a neuropsychological evaluation or brain MRI.

  • Withdrawal from the study at any time, if desired.

  • Pregnancy

  • Contra-indication to MRI:

    • nerve stimulators
    • cochlear implants
    • ferromagnetic foreign bodies close to nervous structures in the eye or brain
    • cerebral shunts
    • dental appliances
  • Legal guardianship or incarceration.
