Functional MRI (fMRI) is an important imaging modality to reveal altered function in neurodegenerative diseases. We hypothesize that functional changes in activation occur earlier and can be measured before structural degeneration is obvious. FMRI can potentially lead to an imaging marker for the early diagnosis of mild cognitive impairment (MCI) and furthermore may predict the development of Alzheimers disease (AD). In this work, we present fMRI results of 8 MCI and 8 normal subjects using different memory paradigms.
