Understanding Alzheimer's Genes: Know Your Family History

Introduction

Alzheimer’s disease is an illness of the brain. It breaks down connections among brain cells and causes these cells to die. Over time, this affects how well a person can remember, think clearly, and use good judgment. Alzheimer’s begins slowly and gets worse over time.

Many people wonder if Alzheimer’s runs in the family. Your chance of having the disease may be higher if you have certain genes passed down from a parent. However, having a parent with Alzheimer’s does not always mean that you will develop it.

This booklet will help you learn:

  • what genes are
  • how genes relate to Alzheimer’s disease
  • what it means if you have a family history of Alzheimer’s
