A study has found that soldiers who receive traumatic brain injuries during war may be at a higher risk of epilepsy even decades after the brain injury occurred. The new research is published in the July 20, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.
"Given the better chances of survival in soldiers fighting in conflicts today, our research suggests that all veterans with a traumatic brain injury should be routinely screened for post-traumatic epilepsy, even decades after the injury," said study author Jordan Grafman, PhD, of the National Institute of Neurological Disorders and Stroke in Bethesda, Md.
Post-traumatic epilepsy is the most common cause of new-onset epilepsy in young adults, with nearly 30,000 new cases per year in the United States.
Of the 199 people, about 44 percent developed post-traumatic epilepsy.
"For a surprising 13 percent, the post-traumatic epilepsy didn't show up until more than 14 years after the brain injury," said Grafman. "This research strongly suggests that veterans with brain injury will require long-term neurology care."
The study also found that the type of seizure changed over time, often becoming more severe (or causing loss of consciousness).
