Alzheimer's disease (AD) is a progressive condition associated with a broad variety of clinical symptoms. These symptoms can, for the most part, be conceptualized as falling within three primary categories: (I) cognitive symptoms, (II) functional symptoms, and (III) behavioral (disturbance) symptoms. All of these symptom categories may potentially respond to specific behavioral intervention approaches to treatment and management. However, at this time, few behavioral approaches have convincingly been substantiated to be effective in treating any of the symptoms in any of these categories.
