摘要: Objective: To determine the rate of progression mild cognitive impairment (MCI) to dementia with Lewy bodies (DLB). Methods: We followed 337 patients MCI in Mayo Alzheimer9s Disease Research Center (range 2–12 years). Competing risks survival models were used examine rates clinically probable DLB and Alzheimer disease (AD). A subset underwent neuropathologic examination. Results: In this clinical cohort, 116 remained as MCI, while 49 progressed DLB, 162 AD, 10 other dementias. Among nonamnestic was 20 events per 100 person-years AD 1.6 person-years. amnestic 17 person-years, 1.5 88% those who developed baseline diagnosis included attention and/or visuospatial deficits. Those more likely have daytime sleepiness subtle parkinsonism. 99% group, memory impairment. Neuropathologic confirmation obtained 24 30 14 18 DLB. Conclusion: a sample, develop AD.
