Alzheimer's disease is irreversible and destroys brain cells, causing thinking ability and memory to deteriorate. At first, someone with Alzheimer's disease may notice mild confusion and difficulty remembering. Eventually, people with the disease may even forget important people in their lives and undergo dramatic personality changes. It is a fatal disease that eventually affects all aspects of a person’s life: how they think, feel, and act. Each person is affected differently. It is difficult to predict symptoms, the order in which they will appear, or the speed of their progression. Currently, there's no cure for Alzheimer's disease, it's important to seek supportive services and tap into your support network as early as possible.
