In this study we assess, by means of resting state fMRI, which resting state networks (RSN) are interested by the Alzheimer's disease (AD) at different stages. In particular we investigated the possible dynamics of corruption of the RSNs when comparing AD subjects with patients affected by mild cognitive impairment (MCI) and healthy controls. We confirmed changes in specific RSNs that are indicative of neurodegeneration. Moreover we found RSNs alterations involving the cerebellum, which could have a compensatory meaning (abnormal recruitments of neurons) leading to increase activity in specific cerebro-cortical areas, along with the worsening of the pathology.
