How it affects the brain Alzheimer’s disease affects the brain by shrinking it. The shrinking affects all functions. The cortex shrivels up, causing damage to areas of thinking, planning and memory occurs. The shrinking also plays a role in the hippocampus. The hippocampus is an area in the cortex where new memories are formed. The ventricles of the brain also grow larger. Alzheimer’s disease also leads to nerve cell death and tissue loss. When scientists or doctors look under a microscope at Alzheimer cells verses healthy cells you will see fewer nerve cells and synapses. Scientists have also found abnormal clusters of proteins called beta-amyloid. These clusters are called plagues. They have also found the dead or dying nerves contain tangles. Tangles are another protein called tau that is twisted. Although research cannot prove what causes the cells to die, it is believed that plagues and tangles play an important role in the death of them. …show more content…
