Brain-injured troops face unclear long-term risks

December 4, 2008

Many of the thousands of troops who suffered traumatic brain injuries in Iraq and Afghanistan are at risk of long-term health problems including depression and Alzheimer’s-like dementia, but it’s impossible to predict how high those risks are, researchers say.

About 22 percent of wounded troops have a brain injury, concluded the prestigious Institute of Medicine — and it urged precise steps for studying how these patients fare years later so chances to help aren’t missed.

The Veterans Affairs Department, which requested the report, and the Pentagon already are taking some of the recommended steps. But a report out Thursday highlights the urgency.

“I don’t think we really knew how big a hole in scientific knowledge there is about blast-induced brain injuries,” said Dr. George Rutherford of the University of California, San Francisco, the report’s lead researcher.

Traumatic brain injury, or TBI, is a signature injury of the Iraq war. Most do not involve penetrating head wounds but damage hidden inside the skull caused by an explosion’s pressure wave. It can range from a mild concussion to severe injury. And because symptoms may not be immediately apparent, troops may not seek care.

“If you have a gunshot wound to some specific part of your brain, I can tell you the consequences,” Rutherford said. But with blast concussions, it’s not even possible to say “if you have six of these, are you six times more likely to have something bad happen to you than if you’ve had one?”

Returning soldiers have reported headaches, dizziness, memory loss, confusion, irritability, insomnia and depression. The military has said most of the TBI-injured troops recover with treatment.

“There’s clearly a whole bunch of people who have mild TBI who have no negative outcomes,” Rutherford agreed.
