Alzheimer’s disease is a brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. Memory problems are one of the first signs of Alzheimer’s disease. People may have trouble remembering things that happened recently or names of people they know. Over time, symptoms get worse, and problems can include getting lost, repeating questions, and taking longer than normal to finish daily tasks. As the disease progresses, people may have trouble learning new things, recognizing family and friends, and communicating. Eventually, they need total care.
