Alzheimer’s disease (AD) is a neurodegenerative disease with characterization of deficits in progressive memory loss, cognitive and behaviour functions. Mild cognitive impairment (MCI) is a predromal stage of AD, displaying cognitive deficit but neither marked functional impairment nor satisfying established clinical criteria for dementia or probable AD. However, not all MCI patients may eventually progress to AD (progressive MCI, pMCI), and some remain unchanged (stable MCI, sMCI), or are recovered from. Therefore, differential diagnosis of MCI types and earlier diagnosis of AD and prediction of disease evolution are difficult
