Alzheimer's disease takes the form of sticky plaques and stringy tangles. These plaques and tangles destroy the neural tissue, thus rendering that part of the brain disabled. As the plaques and tangles progress, the brain shrinks in size and weight. Generally, Alzheimer's targets first the entorhinal cortex, which is a mimory-processing center used for making new memories and recalling old ones (1). Next it goes on to the hippocampus, which is used to form complex memories of objects or events (2). Finally, the plaques and tangles move on to theneocortex, which controls all behavior (3). After this, the neuro tissue is degraded until the components vital for life in the brain are targeted and destroyed.
