Type 2 diabetes mellitus (DM2) is associated with moderate cognitive impairment in verbal memory, mental flexibility, and information processing speed, while other cognitive functions remain relatively unaffected.1 Moreover, epidemiological studies have shown that DM2 patients have a twofold increased risk of developing either vascular dementia or Alzheimers disease.1,2 In the present study we examined whether mild cognitive impairment (MCI) and "cognitive impairment, no dementia" (CIND)two concepts that are used to describe cognitive impairment in the transitional state between normal aging and early dementiacan be applied to the cognitive impairments encountered in a population based sample of DM2 patients. Recently, these concepts have attracted considerable attention, as individuals who meet the criteria for either MCI or CIND are known to have a substantially increased risk of developing dementia.3,4 MCI is defined as a memory deficit without impairments in other cognitive domains.3 Patients with MCI develop Alzheimers disease at an annual incidence
