Two-year outcome of MCI subtypes and aetiologies in the Goteborg MCI study

Abstract

The results suggest that memory impairment alone, or impairment in any one cognitive domain alone, is a rather benign condition. Impairment in several cognitive domains is associated with a more severe outcome over 2 years. Also, 20% of the subjects who progressed to dementia, including Alzheimer's disease, did not show memory impairment at baseline, which suggests that memory impairment is not always the first symptom of even the most common dementia disorders.
