The Alzheimer’s Association says roughly one in nine people age 65 and older have Alzheimer’s disease. More than 7 million Americans are living with the disease.

Alzheimer’s disease is ultimately fatal, but there are several modifiable risk factors for dementia that, if addressed, may help delay the onset of symptoms.
