Mild cognitive impairment: A concept analysis.

Aim: To clarify the concept of mild cognitive impairment (MCI) and identify its attributes to enhance understanding of its implications for nursing practice and research.

Background: MCI is a concept that has evolved, thus clarification of this concept is essential for the advancement of nursing science.

Design: Walker and Avant's eight steps of concept analysis strategy was used.

Data Source: Manuals of mental disorders and databases such as PubMed, Springer, PsychINFO, Cumulative Index to Nursing and Allied Health Literature, and Education Resources Information Center (ERIC) from 1982 to 2018.

Review Methods: A literature search was conducted using keywords such as "mild," "cognitive," "impairment," and "deterioration."

Results: The concept of MCI is defined as the transitional state between cognitive state normal for age and the early manifestation of dementia states. It is characterized by the presence of objective and subjective evidence of impairment in one or multiple cognitive domains, independence in daily activities, can be reversible, and is a risk factor for dementia.

Conclusions: Clarification of MCI serves as a framework for identification, treatment, and interventions that may support healthy aging in older adults.
