Abstract
Mild Cognitive Impairment is a transitional stage between cognitive changes of normal aging and early-stage dementia. Nowadays, the construct of mild cognitive impairment (MCI) is recognized as a pathological condition, not as a normal process associated with age, and is used specifically to refer to a group of individuals who have some degree of cognitive impairment but not full filed all criteria for dementia and not to pose a fundamental commitment in the activities of daily living. MCI originally referred to a memory deficit in the context of non- amnesic functions preserved (amnestic MCI) but now the term includes deficits in other cognitive functions beyond memory. The amnestic MCI is possibly a precursor state to Alzheimer’s disease. Neuropathological data confirm this transition from amnestic MCI to Alzheimer’s disease.
