"Post-Traumatic Stress Disorder Statistics for OEF / OEF AFGHANISTAN * A recent study showed that 18 percent of 45,880 veterans were diagnosed with psychological disorders, including 183 with PTSD. IRAQ * According to a 2005 VA study of 168,528 Iraqi veterans, 20 percent were diagnosed with psychological disorders, including 1,641 with PTSD. * In an earlier VA study this year, almost 12,500 of nearly 245,000 veterans visited VA counseling centers for readjustment problems and symptoms of PTSD. * The Marines and Army were nearly four times more likely to report PTSD than Navy or Air Force because of their greater exposure to combat situations. * Enlisted men were twice as likely as officers to report PTSD. "

"Past studies have shown group therapy to be ineffective on veterans with PTSD, but authors of this study, published in the April issue of the Journal of Traumatic Stress, said the amount of exposure therapy - 60 hours - in this group may be the key to why it works."

Neuron Culture covers a new study on predictors of PTSD in deployed American combat troops. Predicting whether a soldier will break down through combat has been one of the Holy Grails of military psychiatry and the impressive results of this study suggest that this may be getting closer.

"The findings also complement evidence from imaging and clinical studies in humans and other mammals that link depression and PTSD with decreased hippocampal volume. In those studies, researchers had no way of knowing which came first: environmental stress that caused the hippocampus to shrink, or an inherently smaller hippocampus that predisposed certain individuals to depression or PTSD under stressful conditions."

The Department of the Army has finally gone public and acknowledged the alarming rate of suicide among its ranks. While Army leadership is to be commended for breaking the barrier of silence regarding mental illness in the military, the underlying culture of secrecy that has contributed to the current trend is in dire need of reform.

"A new study says Wisconsin veterans are more likely to commit suicide than the general population is. The report says veterans make up 8 percent of Wisconsin's population but committed nearly 21 percent of suicides in the state. Kenneth Black is the secretary of the state Department of Veterans Affairs. He says his department sees the issue of veteran suicide as a growing concern. "

Received the following from the Department of Psychiatry at the Stanford University School of Medicine seeking candidates for a study.

Deploying to Afghanistan, Craig Mullaney writes, "was a slow immersion, like Dante's descent into the Inferno."\n\nOne moment, Mullaney and his Army Ranger platoon waited in an airport terminal at Fort Drum, N.Y. Televisions were tuned to Major League Baseball games. The soldiers ate what one jokingly called their "Last Supper" - rubbery T-bone steaks with Mexican rice.\n\nThey received an intelligence briefing warning them of the dangers awaiting them in Afghanistan, including ticks, cobras and camel spiders that can run more than 30 mph. Then they marched onto a cavernous cargo plane. Two flights and 7,000 miles later, Mullaney and his men stepped out into the dusty, baking heat of an airbase in Kandahar. It was 128 degrees, in the shade.\n\nIn that summer of 2003, Afghanistan had fallen off the front page. Attention had shifted to the war in Iraq. Meanwhile, the Taliban regime that had been toppled by the U.S. invasion following 9/11 was resurgent. Operating from across the border in Pakistan, where Osama bin Laden was suspected to be hiding, Taliban and al-Qaida fighters harassed local villages and Western occupiers.\n\nMullaney's Army Ranger training did not cover desert warfare, which had been dropped in 1995. Studying modern military history at West Point, he took just one paragraph of notes on Afghanistan, involving the Russians' failed experience there in the 1980s.

"If you haven't seen Ilona Meagher's website focused on combat-related post-traumatic stress among US soldiers and veterans, go here. Meagher wrote a book called, Moving a Nation to Care: Post-Traumatic Stress Disorder and America's Returning Troops. And this week, she's gathered a very useful collection of statistics on the military services with some of the following highlights. Better not to quote me directly here; go to Ilona's site and see the sources she cites for the study parameters and context:"

The scans of 42 U.S. soldiers who had served in Iraq or Afghanistan in the recent past showed that, compared with healthy veterans, those suffering from post-traumatic stress disorder (PTSD) had marked differences in some areas of brain activity. The study, presented at the World Psychiatric Association Congress in Italy, suggested identifying certain brain patterns could one day help diagnose PTSD before symptoms appeared and better track treatment, the researchers said.
