Alzheimer’s Disease
Back to Brain DiseasesAlzheimer’s Disease Overview
Alzheimer’s disease is an irreversible brain disease that affects memory, thinking, and the ability to complete daily tasks. Approximately 5 million people in the U.S. have Alzheimer’s disease. It is the most common cause of dementia and accounts for 60 to 80% of all dementia cases. There is currently no cure for Alzheimer’s, and the disease is typically fatal within 10 years of onset.
Read on to learn more about Alzheimer’s disease risk factors, symptoms, and research efforts.

Alzheimer’s Disease Risk Factors
Age is the top risk factor, and the risk of developing Alzheimer’s doubles every five years after age 65. However, about 200,000 people under age 65 have early-onset Alzheimer’s.
Genetic, environmental, and lifestyle factors can play a role in causing dementia-related diseases like Alzheimer’s. The most significant factor in early-onset dementia is genetics. If a person has a parent or sibling with Alzheimer’s, that person has double the likelihood of developing it.
Cardiovascular conditions like high blood pressure, diabetes and high cholesterol may also be contributing factors to Alzheimer’s. In addition, secondary conditions such as stroke can be factors.
