Alzheimer's disease is the most common form of dementia, affecting millions of people worldwide.
The prevalence and incidence rates vary by age, sex, race, and geographic location.
According to the Alzheimer's Association, an estimated 5.8 million Americans were living with Alzheimer's disease in 2020, and this number is projected to increase to nearly 14 million by 2050.
Globally, the World Health Organization estimates that around 50 million people have dementia, with Alzheimer's disease being the most common cause.
The incidence of Alzheimer's disease increases with age, and it is more common in women than in men.
Additionally, certain genetic and environmental factors may increase an individual's risk of developing the disease.
It is important to note that these numbers are estimates and may vary depending on the source and methodology used in the studies.
