The Classic Edition of this foundational text includes a new preface from Holly A. Tuokko, examining how the field of Mild Cognitive Impairment (MCI) has developed since first publication. Bringing together research from multiple studies and perspectives from various countries, the volume identifies MCI as an important clinical transition between normal aging and the early stages of Alzheimer's disease (AD).The up-to-date preface highlights the expansion in research, examining the benefits of various pharmacological, cognitive and behavioral approaches to intervention. Influenced by recent findings in neuroplasticity across the lifespan, the book recognizes the importance of intervention at the earliest stages of the decline trajectory. It revisits the contested diagnostic approaches for MCI as well as the varying prevalence of MCI internationally, yet points to the need for further longitudinal studies to fully understand the condition.Mild Cognitive Impairment continues to provide a comprehensive resource for clinicians, researchers and students involved in the study, diagnosis, treatment and rehabilitation of people with MCI.
