New York University (NYU) School of Medicine, and supported by the National Institutes of Health, Bethesda, Maryland, researchers have found that WTC attack still has its effect in terms of people suffering with inexorable headaches years after the incident.

Sara Crystal, lead author of the study, NYU School of Medicine, said, “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.”

For concluding this researchers studied about 765 people who got themselves registered in the WTC Environmental Health Center of Bellevue Hospital, seven years after the 2001 attack. These people never complained of a headache before the attack took place.

Researchers after investigating those under study found that about 55 per cent people reported being caught in the dust cloud immediately after the attack. And they suffer from headaches as they get exposed to dust.

So it was concluded that those who were trapped in dirt, and smoke immediately after the attack had a higher tendency of reporting headaches.

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