Alzheimer's disease.

Abstract

Dementia is the fifth leading cause of death worldwide. The most common cause of dementia is Alzheimer’s disease (AD). This fully updated and revised chapter comprehensively reviews the latest evidence on diagnosis, assessment, investigations, clinical features, management, risk factors, prognosis, and future potential treatments for AD. Importantly, the chapter explores newer evidence that has changed the way AD is viewed as regards methods of assessment using various scales to determine diagnosis, as well as current and investigative methods of treating AD. Finally, it looks at the states of disease progression, potential disease-modifying drugs for Alzheimer’s disease, and possible therapeutic approaches to treatment and management.
