Health Tools help you make wise health decisions or take action to improve your health.
The cause of Alzheimer's disease isn't clear. It's likely that there are several causes. Alzheimer's disease causes changes or deterioration in certain areas of the brain that control thinking, communication, and behavior. Some of the deterioration may be related to a loss of chemical messengers in the brain (neurotransmitters)—acetylcholine, in particular—that allow nerve cells in the brain to communicate properly.
Some theories have suggested that metals, such as zinc or aluminum, play a role in Alzheimer's disease. But research hasn't found much evidence to support these theories. Experts agree that there is no reason to leave zinc out of your diet or to avoid items that contain aluminum, such as cooking utensils or soda pop cans.
