The most common cause of dementia is Alzheimer’s disease, which is defined as a progressive decline in cognitive, behavioural, and social skills that impairs a person’s ability to function independently.
Alzheimer’s disease affects approximately 5.8 million people in the United States aged 65 and up.
Eighty percent of those are 75 or older.
Alzheimer’s disease is estimated to affect 60-70 percent of the approximately 50 million people worldwide who have dementia.
The disease’s early symptoms include forgetting recent events or conversations.
A person with Alzheimer’s disease will suffer severe memory loss and lose the ability to perform daily tasks as the disease progresses.
There is no known cure so far for Alzheimer’s disease or any treatment that alters the disease process in the brain. Complications from severe loss of brain function, such as dehydration, malnutrition, or infection, resulting in death in advanced stages of the disease.
