In 2009, half a million people in the United States were thought to have early-onset Alzheimer's or other dementia-causing conditions which develops before age 65.

Most cases of Alzheimer's disease develop after the age of 65 and are known as late-onset Alzheimer's.

Thirteen percent of individuals age 65 and older have Alzheimer's disease.

After age 65, the odds of a person having Alzheimer's double approximately every five years.

A person with Alzheimer's usually lives about ten years after the diagnosis is made.

Alzheimer's is the seventh-leading cause of death.
