Alzheimer's disease is a progressive disease that causes the degeneration and death of brain cells. Alzheimer's disease is the leading cause of dementia. A continual decline in thinking, behavior and social skills that interfere with a person's ability to work autonomously. The first signs of illness may be forgetting recent events or conversations. As the disease progresses, a person with Alzheimer's disease develops a severe deterioration in memory and loses the ability to perform daily tasks.
Current medications used to treat Alzheimer's disease may temporarily improve the symptoms or decrease their incidence. These treatments can sometimes help people with Alzheimer's disease to optimize their functions and maintain their independence for a while. Various programs and services can help people with Alzheimer's disease and their caregivers. No treatment can cure Alzheimer's disease or alter the course of the disease in the brain. In advanced stages of the disease, complications due to severe brain dysfunction such as dehydration, malnutrition, or infection result in death
