Washington, Feb 11 (ANI): A study has found that people who were exposed to dust, fumes during the collapse of the World Trade Center on September 11, 2001 still frequently report having headaches.

"We knew that headaches were common in people living and working near the World Trade Center on and immediately after 9/11, but this is the first study to look at headaches several years after the event," study author Sara Crystal, MD, with the NYU School of Medicine in New York City, said.

The study involved 765 people who were enrolled in the Bellevue Hospital World Trade Center Environmental Health Center seven years after the building collapse and who did not have headaches prior to 9/11.

About 55 percent of them reported having exposure to the initial World Trade Center dust cloud.

Headaches in the four weeks prior to enrolment were reported by 43 percent of those surveyed, suggesting that headache is a common and persistent symptom in those exposed to World Trade Center dust and fumes.

People caught in the initial dust cloud were slightly more likely to report headaches than those not caught in the dust cloud, which may indicate that greater exposure may be associated with a greater risk of developing persistent headache.

People with headaches were also more likely to experience wheezing, breathlessness with exercise, nasal drip or sinus congestion and reflux disease after 9/11.

"More research needs to be done on the possible longer-term effects of exposure to gasses and dust when the World Trade Center fell," Crystal said.

"We also need additional studies to understand the relationship between headaches, other physical symptoms, and mental health issues," she added.

Crystal will be presenting more data at the 62nd American Academy of Neurology's Annual Meeting in Toronto April 10 to April 17, 2010. (ANI)
