Abstract
The IQCODE is a retrospective questionnaire for caregivers about changes which occurred in a patient's cognitive and functional efficiency in the previous 10 years of life. Previous studies demonstrated the validity of the IQCODE for the screening of dementia similar to that of traditional cognitive screening tests, with the additional advantage of allowing the detection of cognitive change, rather than just cognitive impairment. The present paper deals with the preliminary results of the validation of the Italian version of the questionnaire in a sample of 45 mild to severely demented patients and 13 patients with mild cognitive impairment (MCI), compared to 20 cognitively intact elderly subjects. The IQCODE demonstrated satisfactory discriminative power for dementia as well as for MCI and a good correlation with the MMSE.
