Facts about Alzheimer's Disease
- Alzheimer's disease is the most common form of dementia among older adults. It involves parts of the brain that control thought, memory, and language and can seriously affect a person's ability to carry out daily activities.
- Although not a normal part of aging, the risk of developing Alzheimer's disease increases with age. Most individuals with Alzheimer's disease are over the age of 65. However, people younger than age 65 also can develop Alzheimer's disease.
- Scientists do not know what causes Alzheimer's disease, but it is believed that it is similar to other chronic conditions and develops as a result of multiple factors rather than a single cause.
Global Alzheimer's Disease
- According to the World Health Organization (WHO), approximately 18 million people worldwide have Alzheimer's disease. By 2025, this estimate is projected to grow to 34 million people, with the highest increase expected among developing countries.
Alzheimer's Disease in the United States
- It is currently estimated that approximately 2.6 million to 5.2 million Americans currently have Alzheimer's disease, depending upon the approach used for identifying individuals with dementia.
- If no cure is developed and present population trends continue, as many as 16 million individuals may have Alzheimer's disease by the year 2050.
- Alzheimer's disease ranks as the 6th leading cause of death among adults aged 18 years and older, and is the 5th leading cause of death for adults aged 65 years and older.
- For people with Alzheimer's disease and other dementias, the total payments for health care, long-term care, and hospice are projected to increase from $183 billion in 2011 to $1.1 trillion in 2050 (in 2011 U.S. dollars).
Current Efforts
A coordinated approach involving public and private partners is needed to address Alzheimer's disease and its devastating effects on individuals, families, and the health care system. There are several new and existing activities currently underway. Some of these efforts are described below. Read More
