What is Alzheimer's disease? Alzheimer's disease is the most common cause of dementia. The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. These symptoms occur when the brain is damaged by certain diseases, including Alzheimer's disease.

There is a genetic component to Alzheimer disease as well.lzheimer disease is, in part, caused by the development of things called neurofibrillary tangles in brain cells that edge out what is otherwise supposed to be there.
