Neuropsychological evaluation of mild cognitive impairment: three case reports.

Recent research on mild cognitive impairment (MCI) has focused on the description of the disorder, its biological markers, and conversion rates to dementia. Studies of cognitive deficits in individuals who present with memory decline but do not fulfill criteria for dementia have analyzed baseline group data according to outcome diagnosis. The application of these findings to the individual person remains problematic. The current article presents three cases with a relatively isolated deficit in memory for word lists but better performance on other memory tests. Questions arising with regards to the MCI criteria are discussed in light of these case reports.
