Prevalence and predictors of diagnosed mild cognitive impairment among Medicare beneficiaries.

ABSTRACT:

Introduction

Mild cognitive impairment (MCI) is a known risk factor for dementia and presents an opportunity for early engagement in preventative strategies, treatment, and advanced planning. However, little is known about MCI diagnosis rates among Medicare beneficiaries.
