|Alzheimer’s disease (or Alzheimer’s syndrome) is the most common form of dementia.
Dementia is a group of brain disorders that gradually destroys brain cells and impairs the ability to function effectively in daily life. Cognitive functioning is slowly affected (memory, reason, judgment, and communication), making it increasingly difficult to carry out daily tasks and activities.
Personality can be also be affected by Alzheimer’s, and behaviors may begin to change as the disease progresses. Characteristically, symptoms of Alzheimer's disease includes becoming anxious, suspicious, or agitated.
In its most severe form, people with Alzheimer’s often reach the stage where they are unable to respond appropriately to their environment and are unable to speak and control their movements.
Because Alzheimer’s disease affects approximately 10% percent of people over 65 and nearly 50% of people over 85 years of age, this form of dementia continues to be the focus of a great deal of research.
