- Clinical interview and visit are executed by expert geriatricians, members of the same geriatric staff who apply diagnostic criteria for dementia (DSM IV), Alzheimer disease (NINCDS ADRDA diagnostic criteria); Vascular dementia (NINDS -AIREN criteria); Lewy Body dementia (third report, DLB consortium); frontotemporal dementia ( 2002 modified Consensus conference criteria). Other cognitive problems were classified as Mild Cognitive Impairment (MCI) following Petersen's criteria or Cognitive Impairment No Dementia (CIND) when cognitive impairments are in areas other than memory and they do not meet whole criteria for dementia. Every diagnostic conclusion is revised by another doctor; in case of discrepancies a third geriatrician, chief of the study, intervenes to arbitrate.
