Alzheimer's disease is the most common cause of dementia, which is a gradual decline in memory, thinking, behavior, and social skills.

Alzheimer's disease is characterized by changes that lead to the accumulation of certain proteins in the brain. Alzheimer's disease causes the brain to shrink and eventually brain cells to die.

It is estimated that 60% to 70% of the approximately 55 million people with dementia worldwide have Alzheimer's disease.

The early sign of the disease is often difficulty in finding words, forgetting recently learned information. Over time, severe memory problems and loss of ability to perform daily tasks develop.

Medications used to treat Alzheimer's disease slow the progression of symptoms.

There is no treatment that cures Alzheimer's disease. As the disease progresses, it is due to severe brain function loss; dehydration, malnutrition, or infection may develop. These complications can result in death.

Repeating questions
Get lost in places know well
