More Vietnam War veterans are asking for help for post traumatic stress disorder.

The disorder was a topic at the Nebraska Vietnam Veterans Reunion Friday.

Only about three percent of Americans have PTSD, but 30 percent of Vietnam veterans admit they suffer from the disorder.

Another 20 to 25 percent have enough symptoms to affects their life.

But not everyone reports their symptoms, and the symptoms can resurface over time.

More than three decades after the war ended, Vietnam Veterans fill a room at the reunion to learn more about PTSD.

Dr. Krista Krebs says she's seeing more veterans from the era seeking help these days, and many for the first time.

"There's just a lot of veterans coming in since the Iraq War started, the second Iraq War started," she said. "More veterans [are] coming in as they retire and have more time and this stuff comes back at them."

Roy Schoen helped organize sessions like the one on PSTD, and as a veteran knows about the disorder first hand.

He remembers one particular incident when his wife touched a hot plate.

"She grabbed it and burned her finger, and I had a total shut down of emotions," said Schoen.

Krebs says symptoms like avoidance and heightened anxiety, anger, or tension are normal reactions to trauma, but many returning Vietnam vets didn't get help or the right help.

"It's only been I would say in the last 20 years that we've gotten some really good solid therapies that we know work well," said Krebs.

But she says there's no cure for PTSD.

"People really do get better. It doesn't take away what happened, of course. That's something that becomes part of the person, but it doesn't have to rule your life and it doesn't have to hurt this bad," said Krebs.

Krebs says treatment options vary, but many include a combination of therapy and medication.

She says, veterans need to reestablish a sense of safety that was lost in a combat zone.
