Alzheimer disease is the most common cause of dementia. Dementia is a loss in mental function that impacts daily life. The ability to learn, remember, and function is slowly lost. It is related to abnormal deposits of protein and twisted fibers in nerve cells in the brain. The cause of this is not known. Less common disease forms include those associated with heart disease and Parkinson disease.
