Alzheimer's Disease is a condition that affects the brain. It causes changes in the way people remember things, think, and behave. People with Alzheimer's have trouble remembering things like names, what happened yesterday, and even how to do everyday tasks like brushing their teeth. As the disease gets worse, their behavior can change, too, and they might become confused or scared. Alzheimer's can't be cured, but there are treatments and therapies to help people cope with the symptoms.
