A synthetic pesticide that's banned in the U.S. may raise the risk for Alzheimer's disease.
DDT has been banned since the early 1970's, but scientists say the chemical can take many years to break down in the environment.

Those with the disease were much more likely to have evidence of DDT in their blood.
The study also found the chemical exposure may increase the severity of the disease.
