Talk Therapy: Off the Couch and into the Lab

Tue, 23 Feb 2010 00:00:00 EST

A remarkably important event has just occurred in the world of psychology: A leading, peer-reviewed journal has published the strongest evidence yet that psychodynamic psychotherapy -- “talk therapy” -- works. In fact, it not only works, it keeps working long after the sessions stop.

Full disclosure: We report this not as disinterested observers, but as psychotherapists and researchers on the process and efficacy of therapy. Our book , “Handbook of Evidence-Based Psychodynamic Psychotherapy,” summarized the body of research through last year and another will follow late this year. Still, we can state as fact: The movement to establish an evidence base for psychodynamic therapy has taken a giant new step forward.

Brain Scan Offers First Biological Test in Diagnosis of Post-Traumatic Stress Disorder

An event such as sexual assault or a battlefield injury is physically agonizing at the time, but it also can eventually sentence a person to a host of mental symptoms--often vivid flashbacks, anxiety and emotional detachment--known as post-traumatic stress disorder (PTSD). The disorder afflicts 3.4 percent of men and 9.7 percent of women in the U.S., according to research estimates. [More]

LSD Returns--For Psychotherapeutics

Thu, 24 Sep 2009 08:00:00 EST

Albert Hofmann, the discoverer of LSD, lambasted the countercultural movement for marginalizing a chemical that he asserted had potential benefits as an invaluable supplement to psychotherapy and spiritual practices such as meditation. “This joy at having fathered LSD was tarnished after more than ten years of uninterrupted scientific research and medicinal use when LSD was swept up in the huge wave of an inebriant mania that began to spread over the Western world, above all the United States, at the end of the 1950s,” Hofmann groused in his 1979 memoir LSD: My Problem Child.

For just that reason, Hofmann was jubilant in the months before his death last year, at the age of 102, when he learned that the first scientific research on LSD in decades was just beginning in his native Switzerland. “He was very happy that, as he said, ‘a long wish finally became true,’ ” remarks Peter Gasser, the physician leading the clinical trial. “He said that the substance must be in the hands of medical doctors again.”

Can fearful memories be erased?

Thu, 03 Sep 2009 18:35:00 EST

In the movie Eternal Sunshine of the Spotless Mind , Joel and Clementine's relationship ends so sourly that the couple elects to have their mutual memories swept away via a non-surgical procedure called "targeted memory erasure." No such tool actually exists. Even the most intense therapies can't completely erase troubling or fearful memories in adults. Yet, if two young rats fall in and out of love--or, more likely, have a close encounter with a subway car--permanent memory erasure may actually be possible, previous research has suggested. So, what happens in a growing rodent brain to cause this change? [More]

Readers Respond on "The Expanding Universe"

Fri, 24 Jul 2009 08:00:00 EST

Quantifying Quandary In " The Post-Traumatic Stress Trap ," David Dobbs reports on a growing number of experts who believe that post-traumatic stress disorder (PTSD) is being overdiagnosed. In support of this argument, Dobbs cites a 1990s study in which researchers asked veterans "about 19 specific types of potentially traumatic events.... Two years out, 70 percent of the veterans reported at least one traumatic event they had not mentioned a month after returning, and 24 percent reported at least three such events for the first time." These memories are assumed to be "new," but it may be that the subjects simply could not bring themselves to put their experiences into words so soon after those experiences occurred and that after some time they could.

The Science of Economic Bubbles and Busts (preview)

Mon, 22 Jun 2009 08:00:00 EST

It has all the makings of a classic B movie scene. A gunman puts a pistol to the victim’s forehead, and the screen fades to black before a loud bang is heard. A forensic specialist who traces the bullet’s trajectory would see it traversing the brain’s prefrontal cortex--a central site for processing decisions. The few survivors of usually fatal injuries to this brain region should not be surprised to find their personalities dramatically altered. In one of the most cited case histories in all of neurology, Phineas Gage, a 19th-century railroad worker, had his prefrontal cortex penetrated by an iron rod; he lived to tell the tale but could no longer make sensible decisions. Cocaine addicts may actually self-inflict similar damage. The resulting dysfunction may cause even abstaining addicts to crave the drug any time, say, the thudding bass of a techno tune reminds them of when they were stoned.

Even people who do not use illicit drugs or get shot in the head have to contend with the [More]

Soldiers' Stress: What Doctors Get Wrong about PTSD (preview)

Mon, 13 Apr 2009 08:00:00 EST

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.

Stevens led the medics tending an armored brigade of 800 soldiers, and his team patched together GIs and Iraqi citizens almost every day. He saw horrific things. Once home, he said he had his share of "nights where I'd wake up and it would be clear I wasn't going to sleep again."
