Mild cognitive impairment (MCI) is considered a transitional state between healthy controls (HC) and Alzheimer’s disease (AD). This study compares the predictive value of neuropsychological evaluation, structural magnetic resonance imaging, diffusion tensor imaging and resting state functional MRI indices able to identify MCI conversion. AD versus HC and converted MCI (cMCI) versus non-converted MCI (ncMCI) presented different features of differentiation. This result suggests adopting advanced MRI techniques to investigate early alterations. Due to the clinical heterogeneity of MCI patients, considering cMCI as AD-like and ncMCI as HC might be inappropriate when attempting to distinguishing between cMCI and non-converted MCI.
