ABSTRACT
INTRODUCTION Dementia-including its most common form, Alzheimer’s disease (AD)—is characterized by progressive memory impairment, confusion, loss of independence, and a variety of other cognitive and functional deficits. AD affects predominantly the elderly and is usually insidious in onset. A patient with AD generally undergoes a relatively rapid progression from being a healthy, independent person to being a completely dependent, uncomprehending person who lacks insight and self-awareness. This progression makes AD one of the most feared disorders in the elderly (1).
