In patients having Alzheimer’s disease the brain is somewhat shrunken and, on postmortum examination, a definite loss of nervous tissue is noted. Examination of the brain tissues under a microscope reveals small bundles of material called senile plaques, scattered throughout the tissues. The more plaques that are present, the worse is the mental condition of the patient. Chemical analysis reveals the presence of the metal aluminum at the core of each plaque and within many of the cells found in the plaques. Evidence is accumulating to indicate that aluminum may be involved in the formation of the plaques, and it is therefore a prime suspect as the initial cause of the disease.
