There are many studies on the neuropsychological profile of mild cognitive impairment (MCI) but the results of investigations specifically addressing its psycholinguistic characteristics have been inconclusive. The present article aims to review the main population-based and experimental studies on language in MCI and to identify the features that help to predict deterioration. Population-based studies have found that the main predictors of MCI and its progression to dementia are measures of verbal fluency, naming and word memory. Experimental studies comparing patients with MCI and matched healthy controls have mainly analyzed performance in different fluency and naming tasks and, to a lesser extent, other dimensions such as comprehension of sentences and texts and production of narrative speech, taking into account its semantic content and syntactic structures.

The results of studies seeking neurological correlates of the processes involved in language deterioration in MCI are discussed. The present review highlights the need to explore new linguistic features of MCI, their relationships with other cognitive processes and their psychophysiological bases. The need for interventions to attenuate deterioration and avoid progression to dementia as far as possible is also discussed.
