Alzheimer's disease is a brain disorder that gets worse over time. It's characterized by c
hanges in the brain that lead to deposits of certain proteins. Alzheimer's disease causes
the brain to shrink and brain cells to eventually die. Alzheimer's disease is the most com
mon cause of dementia — a gradual decline in memory, thinking, behavior and social skills.
These changes affect a person's ability to function.About 6.5 million people in the Unite
d States age 65 and older live with Alzheimer's disease. Among them, more than 70% are 75
years old and older. Of the about 55 million people worldwide with dementia, 60% to 70% ar
e estimated to have Alzheimer's disease.The early signs of the disease include forgetting
recent events or conversations. Over time, it progresses to serious memory problems and lo
ss of the ability to perform everyday tasks.Medicines may improve or slow the progression
of symptoms. Programs and services can help support people with the disease and their care
givers.There is no treatment that cures Alzheimer's disease. In advanced stages, severe lo
ss of brain function can cause dehydration, malnutrition or infection. These complications
can result in death.
