Alzheimer's disease is the only cause of death among the top 10 in America without a way to prevent, cure or even slow its progression.  Today, more than half of all Americans know someone with Alzheimer's. Soon, no one will be left untouched.  Help to change the course of this disease by walking.  Register today for the Walk to End Alzheimer's, the nation's largest event to raise awareness and funds for Alzheimer's disease, the nation's sixth-leading cause of death.  Walk to help our loved ones living with the disease; to support millions of caregivers emotionally and financially; and to speak up on the behalf of all those affected.
