Jonah Lehrer - In Defense Of Therapy

Cool to see a neuroscientist defend therapy. Following this article from Jonah Lehrer (The Frontal Cortex), I want to include a look inside the battle over the DSM-5, also from Wired. We may never know the truth about what happened behind the scenes in the making of the new DSM because of a very restrictive nondisclosure agreement that all insiders were required to sign. That sucks.

If the National Institute of Mental Health (NIMH) have their way, we will not be doing psychotherapy, but rather, clinical neuroscience.

In Defense Of Therapy

Every period has its signature disorder. We live in the age of depression. Consider a brand new survey published in the Archives of General Psychiatry: Between 1998 and 2007, the percentage of Americans being treated for depression increased by more than 20 percent. Other studies estimate that somewhere between 20 and 40 percent of American adults will suffer from depression at some point in their life.

Obviously, there’s a dizzying array of forces that are causing this rise. Part of the problem is diagnosis, as people like Alan Horwitz and Jerome Wakefield have argued. Thanks to changes in the DSM, Horwitz and Wakefield insist that we’ve medicalized sadness, transforming anguish and its synonyms into a clinical condition.

But it remains unknown how much of the rise in depression is accounted for by changes in diagnosis. And I think it’s extremely important to not dismiss the likely possibility that, even if our diagnostic standards had remained constant, there would still be a rise in depression. In other words, is there something about the way we live now that’s making us extremely sad? Are these intensely negative feelings symptoms of a larger societal problem?

Hard questions, no easy answers. In this blog post, I’d like to focus instead on one of the troubling data points in this most recent medical survey, which is that the percentage of depressed subjects seeking psychotherapy for treatment declined dramatically between 1998 and 2007, from 53.6 percent to 43.1 percent. (This drop has come despite the fact that a majority of subjects say talk therapy is their preferred method of treatment.) Needless to say, pills have taken the place of therapists, as more than 75 percent of depressed patients are now treated with anti-depressants, which has led to a dramatic increase in medical spending on the disorder. Between 1998 and 2007, Medicare expenditures for depression increased from $0.52 billion (1998) to $2.25 billion (2007).

When anti-depressants work, they are little blue miracles. But they often don’t work, at least not at rates higher significantly higher than placebo. (Plus, they often have unpleasant side-effects, which leads more than half of patients to stop taking the drugs shortly after the worst symptoms disappear. And then they relapse, which helps explain why patients treated with SSRI’s have relapse rates above 75 percent.) And that’s why I’m troubled by the drop in talk therapy, as most studies demonstrate that the most effective treatment for depression is pharmaceuticals coupled with a good therapist. Furthermore, many different kinds of therapy can be effective. For instance, the same December 2010 issue of the Archives of General Psychiatry also contains an interesting comparative study of anti-depressants and mindfulness therapy in preventing relapse following an extended depressive episode. The mindfulness therapy itself was straightforward stuff, if time intensive. There were eight weekly group sessions of two hours each, plus a full day retreat and optional one-hour meditation classes. The subjects learned how to reflect upon their feelings with “non-judgmental awareness” and “self-compassion.” They were urged to apply their new mindfulness skills to everyday life challenges.

The results were stark. Not surprisingly, patients who escaped depression with the help of anti-depressants, and then stopped taking the drugs, relapsed about 70 percent of the time. The chemical boost was temporary. However, during the 18 month follow-up period, only 28 percent of patients in mindfulness therapy slipped back into the mental illness.

What we often forget is that therapy alters the chemical brain, just like a pill. It’s easy to dismiss words as airy nothings and talk therapy as mere talk. Sitting on a couch can seem like such an antiquated form of treatment. But the right kind of talk can fix our broken mind, helping us escape from the recursive loop of stress and negative emotion that’s making us depressed. Changing our thoughts is never easy and, in severe cases, might seem virtually impossible. We live busy lives and therapy requires hours of work and constant practice; our cortex can be so damn stubborn. But the data is clear: If we are seeking a long-lasting cure for depression, then it’s typically our most effective treatment.

There has been more bickering and more behind-the-scenes chaos in the making of the new version of the Diagnostic and Statistics Manual of Mental Disorders (DSM for short) than most people who have not been following this process could ever imagine.

In my opinion, as a distant observer of the whole process over the past many years, I see two issues at the heart of most of the conflict - money and worldview.

The money issues comes from Big Pharma and their influence over the process - the more things that they can find a way to pathologize and treat with drugs, the more money they make. For example, depression is no more responsive to Paxil than to sugar pills (and has a lot of serious side effects) but its maker brings in billions of dollars a year. So why not treat sadness as part of the depression spectrum, then they can throw some pills at it and make even more money (except that withdrawal from Paxil is sometimes life-threatening).

They other issue in my perspective is worldviews - the mechanistic, objective view that sees mind and consciousness (and anything we might consider a self) as a function of the brain. On the other side are those who value subjective experience as important and possibly prior to brain states (i.e., experience shapes brain chemistry) so that talk therapy can change the brain and make it function better.

In reality, for most of us out here, it's both/and, not either/or - but in the DSM process there seems to be a pissing war. And we, the therapists (and you, the patients) are the real losers.

Inside the Battle to Define Mental Illness

By Gary Greenberg
December 27, 2010 | Wired January 2011

Every so often Al Frances says something that seems to surprise even him. Just now, for instance, in the predawn darkness of his comfortable, rambling home in Carmel, California, he has broken off his exercise routine to declare that “there is no definition of a mental disorder. It’s bullshit. I mean, you just can’t define it.” Then an odd, reflective look crosses his face, as if he’s taking in the strangeness of this scene: Allen Frances, lead editor of the fourth edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (universally known as the DSM-IV), the guy who wrote the book on mental illness, confessing that “these concepts are virtually impossible to define precisely with bright lines at the boundaries.” For the first time in two days, the conversation comes to an awkward halt.

But he recovers quickly, and back in the living room he finishes explaining why he came out of a seemingly contented retirement to launch a bitter and protracted battle with the people, some of them friends, who are creating the next edition of the DSM. And to criticize them not just once, and not in professional mumbo jumbo that would keep the fight inside the professional family, but repeatedly and in plain English, in newspapers and magazines and blogs. And to accuse his colleagues not just of bad science but of bad faith, hubris, and blindness, of making diseases out of everyday suffering and, as a result, padding the bottom lines of drug companies. These aren’t new accusations to level at psychiatry, but Frances used to be their target, not their source. He’s hurling grenades into the bunker where he spent his entire career.

One influential advocate for diagnosing bipolar disorder in kids failed to disclose money he received from the makers of the bipolar drug Risperdal.

As a practicing psychotherapist myself, I can attest that this is a startling turn. But when Frances tries to explain it, he resists the kinds of reasons that mental health professionals usually give each other, the ones about character traits or personality quirks formed in childhood. He says he doesn’t want to give ammunition to his enemies, who have already shown their willingness to “shoot the messenger.” It’s not an unfounded concern. In its first official response to Frances, the APA diagnosed him with “pride of authorship” and pointed out that his royalty payments would end once the new edition was published—a fact that “should be considered when evaluating his critique and its timing.”

Frances, who claims he doesn’t care about the royalties (which amount, he says, to just 10 grand a year), also claims not to mind if the APA cites his faults. He just wishes they’d go after the right ones—the serious errors in the DSM-IV. “We made mistakes that had terrible consequences,” he says. Diagnoses of autism, attention-deficit hyperactivity disorder, and bipolar disorder skyrocketed, and Frances thinks his manual inadvertently facilitated these epidemics—and, in the bargain, fostered an increasing tendency to chalk up life’s difficulties to mental illness and then treat them with psychiatric drugs.

The insurgency against the DSM-5 (the APA has decided to shed the Roman numerals) has now spread far beyond just Allen Frances. Psychiatrists at the top of their specialties, clinicians at prominent hospitals, and even some contributors to the new edition have expressed deep reservations about it. Dissidents complain that the revision process is in disarray and that the preliminary results, made public for the first time in February 2010, are filled with potential clinical and public relations nightmares. Although most of the dissenters are squeamish about making their concerns public—especially because of a surprisingly restrictive nondisclosure agreement that all insiders were required to sign—they are becoming increasingly restive, and some are beginning to agree with Frances that public pressure may be the only way to derail a train that he fears will “take psychiatry off a cliff.”

At stake in the fight between Frances and the APA is more than professional turf, more than careers and reputations, more than the $6.5 million in sales that the DSM averages each year. The book is the basis of psychiatrists’ authority to pronounce upon our mental health, to command health care dollars from insurance companies for treatment and from government agencies for research. It is as important to psychiatrists as the Constitution is to the US government or the Bible is to Christians. Outside the profession, too, the DSM rules, serving as the authoritative text for psychologists, social workers, and other mental health workers; it is invoked by lawyers in arguing over the culpability of criminal defendants and by parents seeking school services for their children. If, as Frances warns, the new volume is an “absolute disaster,” it could cause a seismic shift in the way mental health care is practiced in this country. It could cause the APA to lose its franchise on our psychic suffering, the naming rights to our pain.

This is hardly the first time that defining mental illness has led to rancor within the profession. It happened in 1993, when feminists denounced Frances for considering the inclusion of “late luteal phase dysphoric disorder” (formerly known as premenstrual syndrome) as a possible diagnosis for DSM-IV. It happened in 1980, when psychoanalysts objected to the removal of the word neurosis—their bread and butter—from the DSM-III. It happened in 1973, when gay psychiatrists, after years of loud protest, finally forced a reluctant APA to acknowledge that homosexuality was not and never had been an illness. Indeed, it’s been happening since at least 1922, when two prominent psychiatrists warned that a planned change to the nomenclature would be tantamount to declaring that “the whole world is, or has been, insane.”

Some of this disputatiousness is the hazard of any professional specialty. But when psychiatrists say, as they have during each of these fights, that the success or failure of their efforts could sink the whole profession, they aren’t just scoring rhetorical points. The authority of any doctor depends on their ability to name a patient’s suffering. For patients to accept a diagnosis, they must believe that doctors know—in the same way that physicists know about gravity or biologists about mitosis—that their disease exists and that they have it. But this kind of certainty has eluded psychiatry, and every fight over nomenclature threatens to undermine the legitimacy of the profession by revealing its dirty secret: that for all their confident pronouncements, psychiatrists can’t rigorously differentiate illness from everyday suffering. This is why, as one psychiatrist wrote after the APA voted homosexuality out of the DSM, “there is a terrible sense of shame among psychiatrists, always wanting to show that our diagnoses are as good as the scientific ones used in real medicine.”

Since 1980, when the DSM-III was published, psychiatrists have tried to solve this problem by using what is called descriptive diagnosis: a checklist approach, whereby illnesses are defined wholly by the symptoms patients present. The main virtue of descriptive psychiatry is that it doesn’t rely on unprovable notions about the nature and causes of mental illness, as the Freudian theories behind all those “neuroses” had done. Two doctors who observe a patient carefully and consult the DSM’s criteria lists usually won’t disagree on the diagnosis—something that was embarrassingly common before 1980. But descriptive psychiatry also has a major problem: Its diagnoses are nothing more than groupings of symptoms. If, during a two-week period, you have five of the nine symptoms of depression listed in the DSM, then you have “major depression,” no matter your circumstances or your own perception of your troubles. “No one should be proud that we have a descriptive system,” Frances tells me. “The fact that we do only reveals our limitations.” Instead of curing the profession’s own malady, descriptive psychiatry has just covered it up.

The DSM-5 battle comes at a time when psychiatry’s authority seems more tenuous than ever. In terms of both research dollars and public attention, molecular biology—neuroscience and genetics—has come to dominate inquiries into what makes us tick. And indeed, a few tantalizing results from these disciplines have cast serious doubt on long-held psychiatric ideas. Take schizophrenia and bipolar disorder: For more than a century, those two illnesses have occupied separate branches of the psychiatric taxonomy. But research suggests that the same genetic factors predispose people to both illnesses, a discovery that casts doubt on whether this fundamental division exists in nature or only in the minds of psychiatrists. Other results suggest new diagnostic criteria for diseases: Depressed patients, for example, tend to have cell loss in the hippocampal regions, areas normally rich in serotonin. Certain mental illnesses are alleviated by brain therapies, such as transcranial magnetic stimulation, even as the reasons why are not entirely understood.

Some mental health researchers are convinced that the DSM might soon be completely revolutionized or even rendered obsolete. In recent years, the National Institute of Mental Health has launched an effort to transform psychiatry into what its director, Thomas Insel, calls clinical neuroscience.
