Abstract
This article presents a brief overview of mild cognitive impairment in older adults, considering its main anticipating precursors, and the risk factors that may accelerate the processes of cognitive aging, which increases the likelihood of being diagnosed with MCI. In turn, the presence of MCL increases the risk and eventual transition to dementia, particularly Alzheimer’s dementia. Moreover, the article describes the different forms cognitive impairment may present itself, and also reviews MCI associated with depressive symptoms, Parkinson’s disease and other degenerative diseases of the CNS. This revision accounts for recent and relevant findings regarding cognitive dysfunction in the elderly, who represent a growing share of national and global populations.
