were more likely converted to dementia (1 year 16.7 vs 37.5 vs 69.2%; 2 year 33.3 vs 50.0%, and 76.9%) (Figure.1).The difference in conversion rates were significant at both 1 year (p<0.001) and 2 year (p1⁄40.004). The positive likelihood ratio (LR+) of mixed type MCI converting to dementia was 15.63 and 9.16 at 1 and 2 year respectively when comparing with MCI of Alzheimer’s etiology. Conclusions: The overall dementia conversion rate of MCI is high and up to 40% in 2 years. Subtype of MCI has significant impact on rates of progression to dementia.
