Mild cognitive impairment (MCI), the presence of cognitive difficulties without having dementia, is viewed as a preclinical state for Alzheimer’s disease (AD) or another dementing illness. With the burden of AD expected to increase, research efforts have focused on interventions to delay the progression of MCI to AD. In this review, we first discuss the current conceptual understanding of MCI. Then, we outline a simplified approach to help clinicians diagnose MCI. Finally, we provide an overview of how to address the clinical needs of individuals with MCI.
Key words: mild cognitive impairment, Alzheimer’s disease, diagnosis, prognosis, treatment.
