Mild Cognitive Impairment: A Comprehensive Review

 Title:

                Mild Cognitive Impairment: A Comprehensive Review

Abstract:

This research article provides a comprehensive review of mild cognitive impairment (MCI), an intermediate stage between normal aging and dementia, focusing primarily on its definition, etiology, diagnostic criteria, progression, and potential interventions. Drawing from various research-based sources and relevant books, the article aims to enhance understanding of MCI, its clinical manifestations, and implications for individuals and healthcare systems. Furthermore, it explores current research advancements and future directions in the field of MCI.

Keywords: Mild cognitive impairment, MCI, cognitive decline, etiology, diagnostic criteria, progression, interventions, research advancements

1. Introduction

   - Definition and significance of mild cognitive impairment

   - Distinction between normal aging, MCI, and dementia

2. Etiology of Mild Cognitive Impairment

   - Neurodegenerative causes: Alzheimer's disease, Lewy body dementia, etc.
