Exposure to the banned insecticide DDT may be linked to Alzheimer’s disease.

In a small study, people with Alzheimer’s were much more likely to have higher levels of DDE, a metabolic byproduct, in their blood.

Even though the pesticide was banned in the U.S. 40 years ago, traces remain in the soil and some is present in imported agricultural products.

This doesn’t mean DDT causes Alzheimer’s, but the relationship deserves more study.
