mild cognitive impairment
A clinical syndrome of cognitive decline greater than expected for age but not severe enough to meet dementia criteria.
Full Definition
Mild cognitive impairment (MCI) represents an intermediate stage between normal cognitive aging and dementia. Individuals with MCI experience cognitive changes that are noticeable to themselves or others but do not significantly interfere with independence in daily functioning. MCI can affect various cognitive domains including memory (amnestic MCI), executive function, attention, or language (non-amnestic MCI). While MCI increases the risk of developing dementia, particularly Alzheimer's disease, some individuals remain stable or even improve over time. The condition requires careful monitoring and may benefit from cognitive interventions and lifestyle modifications.
Usage
Usage note: Spell out on first use, then use MCI; distinguish between amnestic and non-amnestic subtypes.
