Progression to dementia in a population with amnestic mild cognitive impairment: clinical variables associated with conversion

The aim of this study was to investigate clinical predictors of, and rates of conversion to, dementia syndrome in a case series of patients with amnestic mild cognitive impairment (aMCI). Two hundred and eight aMCI subjects were followed over a six-year period. A lower Mini Mental State Examination score was a significant predictor of dementia, and mild cognitive impairment patients with behavioral and psychiatric symptoms showed a faster conversion rate.
