According to a study published in the Journal of the American Medical Association (JAMA) - Neurology, Alzheimer's patients have nearly four times the amount of DDT in their brains as do patients without the disease.

Currently, it is the 6th leading cause of death in the USA, with the death rate increasing dramatically over the past decade.
