This can be attributed to denial, where cognitive impairment is attributed to normal aging or lack of insight, and the idea that nothing can be done.9,10 If primary care physicians wait for obvi-ous symptoms of dementia before taking action, the diagnosis is delayed, often by several years, and this can delay the initiation of support for patients and their caregivers.11 Early detection by means of screening might prevent such delays in this vulnera-ble group of patients, who do not easily request help. However, it is feared and reported that after diagno-sis these patients may suffer from feelings of shock, anger, fear, and negative effects on their self-esteem.12 On the other hand, the vast majority of patients with mild dementia wish to be fully informed.13 Furthermore, it was initially feared that these patients would become depressed after diagnosis, but most of them do not.14 Although there is still insufficient evi-dence to recommend or disapprove of screening for dementia and cognitive impairment in asymptomatic persons, it is worthwhile continuing with research on new screening methods.11,15,16 Self-reports on the IQCODE in
