PTSD

Ed Yong, echoed by Mike the Mad biologist PhysioProf asks what the heck investigative science journalism would look like. I hope to write more extensively on this soon. In the meantime, a few observations:
To ponder this question -- and to do investigative reporting -- I think it helps to have a sense of the history of science, which embeds in a writer or observer a sense of critical distance and an eye for large forces at work beneath the surface. Machinations in government surprise no one who has studied the history of government and politics. Likewise with science.
Science -- the search…

See also The American Prospect on How Big Pharma Intends to Kill the Public Option. I should add this campaign is having an effect: On the radio this morning I heard NPR Steve Insky Inskeep vigorously press the "public plan as trojan horse" attack on Kathleen Sibelius; I can only hope he'll as vigorously ask people such as…

What if you could predict which troops are most likely to get PTSD from combat exposure -- and takes steps to either bolster them mentally or keep them out of combat situations? A new study suggests we could make a start on that right now -- and cut combat PTSD rates in half by simply keeping the least mentally and physically fit soldiers away from combat zones.
The study was part of the Millenium Study, huge, prospective study in which US Department of Defense researchers have been tracking the physical and mental health of nearly 100,000 service…
ddobbs | June 3, 2009Forgive my recent blogopause. i was fishing, and then traveling, and then writing rather head-down intensely -- all activities I have trouble mixing with blogging and social media such as Twitter, which I've also left idle these last days.
So what gives with all that? I often find it awkward to switch between blogging or twittering and engaging deeply immersive physical activities. This hiatus, for instance, started when I went fishing last Tuesday on Lake Champlain for salmon -- a piscatorial retreat before a highly engaging work trip to NY, DC, and environs to talk to scientists and see my…

As the comments and correspondence about my PTSD story and posts accrue, I've been pondering ways to pull out some of the most interesting, powerful, and affecting. I finally decided to just start posting some, sometimes with commentary, sometimes without. This is a story of many different colors and textures.
I'll start with this excerpt from a long, eloquent blog response to my story about PTSD at Scientific American by Kayla Williams, a vet of the Iraq War who blogs at VetVoice. Williams is accumulating quite a strong run of posts there, including posts on torture, being a woman veteran…
ddobbs | April 20, 2009Who stands most at risk of PTSD? A new study of PTSD in US veterans of the current Iraq and Afghanistan wars suggests that you can identify the most vulnerable -- soldiers who stand 2 to 3 times the risk of their peers -- with fairly simple measures of mental and physical health.
The study, conducted by the U.S. Navy's Tyler Smith and collegues, is part of an ongoing longitudinal study of over 150,000 U.S. soldiers. The Millennium Cohort Study began collected comprehensive health data on U.S. soldiers in 2001. This study draws on that data to compare health status before deployment to Iraq…
ddobbs | April 13, 2009One hopes there's a good explanation for this somewhere: According to this AP story, the number of people collecting VA benefits for being POWs exceeds -- by hundreds -- the number of actual POWs ever held (much less still alive). From the AP:
Prisoners of war suffer in ways most veterans don't, enduring humiliating forced marches, torture or other trauma that may haunt them long afterward. In partial recompense, the government extends them special benefits, from free parking and tax breaks to priority in medical treatment.
Trouble is, some of the much-admired recipients of these benefits…
amillikan | April 9, 2009How accurately can medical professionals distinguish post-traumatic stress disorder from related conditions? Is it better to be safe than sorry, or is overdiagnosis hurting patients rather than helping them? These are some questions that ScienceBlogger and freelance journalist David Dobbs addressed in his article in the April edition of Scientific American, bringing light to data that suggests PTSD may be grossly overdiagnosed in soldiers returning from combat. The article's publication has prompted thoughtful discussion with counter examples that led Dobbs to the conclusion that PTSD is…
ddobbs | April 8, 2009When you propose that we are overdiagnosing PTSD in vets, you run into not only a lot of flak but many offerings of evidence suggesting that we're missing a lot of cases. Since publishing my article on PTSD, I've received those arguments directly in comments, and on Wednesday, April 8, Salon published an article, "I am under a lot of pressure to not diagnose PTSD," by Michael de Yoanna and Mark Benjamin, that offers unsettling evidence that at least some doctors working for the VA are being pressed to not diagnose PTSD in combat vets.
So which is it? Are we under- or overdiagnosing PTSD in…
ddobbs | April 5, 2009Heads-up dept:
I'll be discussing I discussed "The Post-Traumatic Stress Trap," my Scientific American story on PTSD, at noon, Monday, April 6, on NHPR's "Word of Mouth." You can listen to the 7-minute segment here, following a very brief intro to the program. Link to the station's website here.
ddobbs | April 3, 2009What are the relative strengths and weaknesses of long-form, slow-bake, "mainstream" journalism and the idiom we call the blogosphere? As per Bora, the meaning of these terms are shifting as we speak. Last night, using my recent story and blogging on PTSD as a point of focus, I put in my latest two cents on this subject at my talk -- actually a long conversation with host and audience -- at the NYU Science, Health and Environmental Program's "Inside-Out" lecture series.
This was a crowd of writers, journalism profs, and journalism students, and I think we were all surprised at how many…
ddobbs | March 26, 2009A heads-up: to those in or near NYC:
Tuesday, March 31, at 6 pm, at 20 Cooper Square in NYC, I'll be giving a talk/discussion on blogging and long-form journalism -- particularly on the different demands, pros and cons, possibilities and constraints, and reader and writer experiences those two different modes of writing (and reading) impose and offer.
The event is part of the NYU journalism Science, Health, and Environmenatl Reporting programs's "Inside-Out" series. WSJ science columnist and former NASW president Robert Lee Hotz will sit down with me to discuss this and other topics.
We'll…
ddobbs | March 24, 2009Skip this post if you don't want to read a writer responding point by point to a self-indulgent, insubstantial attack by a major academic.
I should say right off that I've long admired the more measured critiques that J. Douglas Bremner, a PTSD researcher and professor of radiology and psychiatry at Emory University, has offered about the pharmaceutical industry's exploitation of the neurochemical model of depression. My regard for this work made his critique of attack on my article about PTSD, "The Post-Traumatic Stress Syndrome," all the more disappointing.
I'm not disappointed because…
ddobbs | March 20, 2009A few weeks ago, Matt Stevens, the National Guard captain and medic who served in Iraq and whom I mentioned in my Scientific American article, "The Post-Traumatic Stress Trap, wrote me an email about the social unease he often encountered when he showed any behavior that might remind people he had served in Iraq -- a greater seriousness, an impatience with petty concerns or inefficiency, or even just talking about the place.
I have begun to think of military PTSD as to some extent a civilian problem rather than a soldier problem. To expand slightly here; civilians/politicians send soldiers…
ddobbs | March 18, 2009It didn't take long for my Scientific American story on PTSD to draw the sort of fire I expected. A doctor blogging as "egalwan" at Follow Me Here writes
[Dobbs] is critical of a culture which "seemed reflexively to view bad memories, nightmares and any other sign of distress as an indicator of PTSD." To critics like this, the overwhelming incidence of PTSD diagnoses in returning Iraqi veterans is not a reflection of the brutal meaningless horror to which many of the combatants were exposed but of a sissy culture that can no longer suck it up.
Doctor or not, he's seeing politics where my…
ddobbs | March 16, 2009Below are materials supplementing my story "The Post-Traumatic Stress Trap," Scientific American, April 2009. (You can find the story here and my blog post introducing it here.) I'm starting with annotated sources, source materials, and a bit of multimedia. I hope to add a couple sidebars that didn't fit in the main piece -- though those may end up at the main blog, so you may want to keep an eye there or subscribe via RSS or Atom.
Main sources and documents in "The Post-Traumatic Stress Trap."
These are organized by story section, roughly in the order the relevant material appears.…

My story in the April 2009 Scientific American story, "The Post-Traumatic Stress Trap", just went online. Here's the opening:
In 2006, soon after returning from military service in Ramadi, Iraq, during the bloodiest
period of the war, Captain Matt Stevens of the Vermont National Guard began to have a problem with PTSD, or post-traumatic stress disorder. Stevens's problem was not that he had PTSD. It was that he began to have doubts about PTSD: the condition was real enough, but as a diagnosis he saw it being wildly, even dangerously, overextended.

edyong | January 11, 2009You've just been in a horrific car crash. You're unharmed but the vividness of the experience - the sight of a looming car, the crunching of metal, the overwhelming panic - has left you a bit traumatised. You want something to help take the edge off and fortunately a doctor is on hand to prescribe you with... Tetris.
Yes, that Tetris. According to Emily Holmes from the University of Oxford, the classic video game of falling coloured blocks could prevent people who have suffered through a traumatic experience from developing full-blown post-traumatic stress disorder (PTSD). As ideas go, it's…

One of the practical issues in doing neuroscience in humans is that you have a problem determining causation.
Say I do an imaging study with a neurological disease and find that the activity in a certain brain region is consistently lower. Do I know whether that reduced activity is causing the disease or whether it is just secondary? It is often really hard to tell in humans. If it were an animal study, we could just lesion the area in experimental animals and see if they were still capable of getting the disease. However, there are diseases where good animal models are lacking, and…
