Alzheimer's disease is the most common form of dementia among older people. People with Alzheimer's disease typically show signs of memory loss, confusion, and impaired judgment. Other symptoms can include restlessness, a deterioration of language skills, and an impaired ability to understand visual information. In most cases, the brain tissue of someone with Alzheimer's disease contains abnormal protein clumps and tangled bundles of fibers. While Alzheimer's disease is not a normal part of aging, a person becomes more likely to develop this condition as he or she gets older. In fact, early signs of the disease are often missed because they closely resemble the natural signs of aging. As of yet, there is no cure for Alzheimer's disease and its exact causes are still unknown. There are, however, some medications that can help treat the disease's symptoms. People with Alzheimer's disease continue to live for an average of 8 to 10 years after they are diagnosed, though some people live for as many as 20 years after their diagnosis.
