It is estimated that some 30 million people suffer from Alzheimer’s disease worldwide. In the United States, over five million Americans, or one in nine, suffer from dementia in the advanced stages of Alzheimer’s disease. Estimates say that the number of Alzheimer’s patients is likely to triple in the next 20-30 years, as people are living longer lives.
Alzheimer’s disease is a progressive, neurodegenerative disease that occurs when nerve cells in the brain die. The disease can cause impaired memory, confusion, personality and behavior changes, impaired judgment, and impaired communication. Dr. Reisa Sperling, Director of the Center for Alzheimer Research and Treatment at Brigham and Women’s Hospital (BWH) calls it the “epidemic of Alzheimer’s.”
