- People who were near the World Trade Center around the 9/11 attacks have had headaches for years.
- Other symptoms are wheezing, shortness of breath, sinus congestion and acid reflux.
- Studying the health effects of disasters will help future first responders.
The 9/11 terrorist attacks happened nearly a decade ago, but people continue to suffer from the event, both physically and psychologically.
In a new, preliminary study, scientists found that nearly half of people who lived and worked near Ground Zero around the time of the attack have experienced persistent headaches for years afterward.
Scientists still can't say how -- or even if -- the event caused headaches to start, but follow-up research might help emergency responders better deal with future disasters, both natural and man-made.
"Headaches can have a huge impact on the ability to function," said Joan Reibman, medical director of Bellevue Hospital World Trade Center Environmental Health Center "This is a symptom that should not be overlooked."
