It's still unclear what caused a soldier to open fire on his comrades at Fort Hood, but this shooting has put Post Traumatic Stress Disorder back in the spotlight.

Major Nidal Malik Hasan treated soldiers suffering from PTSD and now, he's blamed for the shooting rampage that killed 13.

While investigators haven't confirmed a motive, Hasan listened to graphic descriptions of war everyday and some are wondering if secondary PTSD could be a factor.

The shooting at Fort Hood is one of the largest shootings to take place on a U.S. military base. When tragedies like this happen, the mental state of those involved is always of concern.

"With the current situation in the United States with the war, the incidents of PTSD is becoming more known and talked about in the community because of the fact that we have returning military veterans coming back from the war," said David Miers, a counselor at Bryan LGH Medical Center.

Post Traumatic Stress Disorder can happen to anyone who survives a frightening event.

"They're irritable, easily startled, they might see more anger,"said Miers. "A combination of many different symptoms that occur for one month or longer, then typically a diagnosis of PTSD is given."

But, Miers said many PTSD sufferers don't seek help.

"Unfortunately there's individuals who don't seek treatment because of the fact of the stigma attached to mental health," said Miers. "They do see it as a sign of weakness and that's actually false."

Instead, Miers said it's a sign of strength because the person is reaching out to end his or her suffering.

"It's definitely important to seek help because if you don't seek help then those symptoms continue with your daily living and seeking treatment can then help turn things back around again," said Miers.
