Neuroimaging tools to rate cognitive impairment

Abstract

Various neuroimaging techniques have been employed to detect the subtle brain changes related to mild cognitive impairment (MCI) and Alzheimer's disease (AD). Current areas of interest in neuroimaging include the detection of predictive indicators, prognostic values and the effects of treatment, as well as the features of disease. In this article, the findings of structural studies, functional imagings and white matter lesions in MCI are reviewed. Several cases of MCI are presented, and the usefulness of neuroimaging in the prediction of the treatment course and prognosis of MCI is evaluated.
