Study Suggests Possible Link to Alzheimers

A new study indicates there may be a link between a person's exposure to the pesticide DDT and their chances of developing Alzheimer's disease.

Researchers in the U.K. found Alzheimer's patients had four times as much DDT lingering in their bodies as people without the disease. The pesticide has been banned in the U.S. and elsewhere for several decades due to health and environmental concerns. However, DDT is still recommended by the World Health Organization for use in controlling malaria. It can also show up in some foods imported to the U.S.

Researchers stress that more evidence is needed.
