Alzheimer (altz-hy-mer) disease (AD) causes major changes to occur in the brain, making it difficult to remember, learn, and make decisions. Researchers don’t know what causes AD, but research has shown that the brains of people who have this disease develop abnormal clumps (called plaques) and tangles of fibers, which interfere with the way brain cells communicate.
