Alzheimer's and the brain

Alzheimer's disease or other dementias can lead to nerve cell death and tissue loss in the brain. It is a result of abnormal clusters of protein fragments called plaques that build up between the nerve cells, as well as tangles, which are dead and dying nerve cells. Over time, the brain shrinks dramatically, affecting nearly all its functions and causing a variety of symptoms to appear.
