  1. CI: cognitive impairment (CInD and DEM). NoCI: no cognitive impairment. CInD: cognitive impairment without dementia. DEM: dementia. NoDEM: no dementia (NoCI and CInD).
  2. MMSE: MiniMental State Examination. MMSEc: MMSE with corrected scores. MIS: Memory Impairment Screen.
  3. The figures are n° of subjects (percentage) or mean ± sd; figures in square brackets = n° subjects able to take the MIS
