A US study has found a possible link between traces of pesticide DDT, found in the blood, and Alzheimer’s disease.
Researchers found the group of 86 people with Alzheimer’s disease who were tested had on average 3.8 times more DDE (a DDT by-product) in their blood, than the 79 people tested who did not have Alzheimer’s disease.
Dr Doug Brown, Director of Research and Development, Alzheimer’s Society said that while this wasn’t the first time DDT had been linked to health problems, it was hard to draw any firm conclusions from this small sample of people from the United States.

Widespread agricultural use of DDT is banned in most parts of the world. There has been a ban on the use of DDT in the US since the 1970s, the UK and Australia since the 1980s.
