Defining the competent psychiatrist

psychwclientWhat defines a competent psychiatrist?  To staunch critics of the field, perhaps nothing.  Some believe psychiatry has done far more harm than good, or has never helped anyone, rendering moot the question of competency.  What defines a competent buffoon?  A skillful brute?  An adroit half-wit?  Having just finished Robert Whitaker's Anatomy of an Epidemic: Magic Bullets, Psychiatric Drugs, and the Astonishing Rise of Mental Illness in America (Crown, 2010), a reader might easily conclude that psychiatric competency is a fool's errand.  From directing dank 19th Century asylums, to psychoanalyzing everyone for nearly anything during much of the 20th Century, to doling out truckloads of questionably effective, often hazardous drugs for the past 35 years, perhaps psychiatry is beyond redemption. Of course, I don't think so.  For one thing, critics often disagree about what is wrong with the field.  For every charge of over-diagnosis and overmedicating, another holds that debilitating disorders are under-recognized and under-treated.  A charge that psychiatry has become too "cookbook" and commodified is answered by the complaint that it is too anecdotal and not sufficiently "evidence-based."  Claims that the field stumbles because it is subtle, complex, and understaffed by well-compensated specialists, are met with counter-claims that checklists in primary care clinics can do most of the heavy lifting at less expense.  Contradictory criticisms offer no evidence that the field is faultless.  But the confusion does suggest that psychiatry's limitations reside at a different level of analysis than that engaged by its critics.

For another thing, the undeniable shortcomings of psychiatry don't make the patients disappear.  Whether the field teems with genius humanitarians or raving witchdoctors, there are still families watching their teenage daughters starving themselves to death; beloved aunts and uncles living unwashed and mumbling to themselves on the street; people ending their lives out of temporary tunnel-vision; tormented souls imprisoned in their homes by irrational fears.  And our society still harbors a nagging ethical sense that a crime is committed only when a person knows what he's doing — and that when he doesn't, he deserves help not punishment.

We can admit that psychiatrists are (at times meddlesome) do-gooders who take on misery and heartache and uncontrolled destructive behavior despite deep controversies over how best to help.  It's the same role filled, in different times and places, by clergy, by family, by shamans, by the village as a whole.  Every society fills it by someone.  This is the modest starting point that bootstraps a meaningful definition of psychiatric competency.

Lists of "core competencies" are issued by the Accreditation Council for Graduate Medical Education (ACGME) for psychiatry residents, and by the American Board of Psychiatry and Neurology (ABPN) for board-certified psychiatrists.  Both organizations categorize psychiatric competency under the six headings established by the ACGME for all medical specialties: Patient Care, Medical Knowledge, Interpersonal and Communications Skills, Practice-Based Learning and Improvement, Professionalism, and Systems Based Practice.  (These categories are also used by the Accreditation Council for Continuing Medical Education [ACCME], so that continuing education required to maintain one's medical license addresses one or more of these competency areas.)  A review of either of these detailed lists reveals two important truths.  First, a committee can make any aspirational standard byzantine and lifeless.  And second, in the eyes of  ACGME and ABPN at least, it's not so easy to be a competent psychiatrist.

However, these official competencies are unlikely to satisfy skeptics, nor do they get to the heart of the matter.  No such list can be exhaustive: the ABPN includes knowledge of transcranial magnetic stimulation, presumably a recent addition, but fails to require knowledge of specific pharmaceuticals.  Focus areas such as addiction, forensic, and geriatric psychiatry are mentioned, but not administrative or community psychiatry.  The linguistic philosopher Ludwig Wittgenstein argues that our inability to precisely define natural categories, even simple nouns like "chair," is a feature of language itself, not of psychiatric competence specifically.  Accordingly, any catalog of psychiatric competencies, whether intended to be comprehensive or a "top ten" list, captures some, but not all, of what constitutes a competent psychiatrist.

As implied above, the starting point, although not the end point, for defining the competent psychiatrist is intent.  A psychiatrist aims to relieve suffering in an uncertain human domain.  Brought to bear are skills, knowledge, and personality factors ("professionalism" etc) which bring this goal closer.  These cannot be listed exhaustively: virtually the whole of human knowledge and experience can inform one's understanding of a patient's emotional turmoil.  The best we can say, I believe, is that a competent psychiatrist is curious, has a wide fund of knowledge and life experience, and aims to keep an open mind.  Some of this knowledge certainly should be biomedical.  But knowing about the psychology of aging, common stressors such as job loss and divorce, gender differences, and many other areas are hardly less important. The practitioner's proclivity to observe the human condition both scientifically and humanistically is ultimately a better gauge of competence than whether a specific treatment modality such as TMS has been added to a long list, or whether the practitioner is able to cough up a specific fact.

Given the controversy and uncertainty in the field, another essential of competent practice is humility.  In most cases we don't know the etiology of what we're treating.  Any treatment we offer helps some patients but not others, and nearly always carries risk.  Whitaker makes many good points along these lines.  A competent psychiatrist tempers his or her urge to intervene with the realization that the road to hell is often paved with good intentions.  Psychiatrists virtually always mean well, and (contrary to some critics) help our patients far more often than not.  Nonetheless, a competent psychiatrist is always ready to admit misjudgment or miscalculation.  Self-correction is a feature of competence in psychiatry as well as in many, perhaps all, other domains of human expertise.

For another take on the competent psychiatrist, arriving at a similar endpoint using different reasoning, see this 2011 post by Dr. Raina.

I wrote above that psychiatry's limitations may reside at a different level of analysis than that engaged by its critics.  Psychiatry is a hard job because the brain is the most complex organ, because normality is so hard to define, because human development is a subtle interplay of nature and nurture, and because we don't understand the root causes of many forms of mental distress.  But even if we did know and understand these far better than we do now, the field would still be fraught with controversy and uncertainty.  Our attitudes regarding responsibility, free will, conformity versus deviance, and how we treat each other reflect our politics and deeply held values.  Psychiatry serves as a lightning rod for strong feelings around these matters.  By its very nature, it always will.  Psychiatrists must accept that many will view us skeptically, some with hatred — and others with undeserved adoration — and not let this dissuade us.  A competent psychiatrist hears criticism from individual patients and the public, neither dismissing it unthinkingly, nor allowing it to lead to demoralization and defeat.

Enjoying clinical uncertainty

Uncertainty-is-an-uncomfortableLucia Sommers of the Department of Family and Community Medicine at UC San Francisco commented on my last post, noting that clinical uncertainty among primary care physicians (PCPs) is usually regarded as tolerable at best.  She was delighted that I called such uncertainty intellectually attractive, and something to embrace in psychiatry.  Sommers and her coauthor John Launer recently published a book that argues for managing clinical uncertainty in primary care using "collaborative engagement with case-based uncertainty in the setting of small groups of clinicians."  This contrasts with medicine's tradition of practitioners working independently.  In her comment, Sommers asked me to describe how psychiatrists manage clinical uncertainty, and specifically whether "supervision" — cases "presented for discussion to at least another psychiatrist if not a small group," similar to what she advocates for primary care physicians — is a good strategy in my experience.  This post is my response. At its most fundamental level, human psychology exists to manage uncertainty.  Confronted with an incomprehensible, threatening world, the infant soon differentiates "good" from "bad."  Initially a crude split without nuance or shades of gray, this primitive psychological distinction,  second only to distinguishing "self" from "other," represents a huge step forward.  It sets the stage for approach versus avoidance — the first "management" the infant undertakes.  Further psychological development allows subtler gradations to improve upon this harsh dichotomy.  Developmental psychology describes how secure attachment with caretakers, and an increasingly stable sense of self, contribute to tolerance of uncertainty.  With normal development, and under most circumstances, we no longer cling desperately to sharp black-or-white categories.  We make finer distinctions, and can also tolerate degrees of uncertainty.

Adult development takes this process further.  Mastery of an academic or occupational field solidifies a stable professional identity, which contributes to comfort with uncertainty.  Many years ago I learned a type of computer programming from my friend, an accomplished software engineer.  I felt anxious when confronted with programming challenges:  Would I fail to discover the solution?  Waste long hours trying?  Feel stupid in the end?  In contrast, my friend felt no such anxiety.  He explained that even when he was uncertain how to solve a problem, he knew he soon would, or at least would soon recognize it was impossible.  He was able to wrap his arms around the whole field in a way I could not.  Uncertainty for him no longer carried implications of permanence, nor of personal failure, i.e.,  narcissistic injury.  It wasn't threatening.  In this frame of mind, a programming challenge is merely a puzzle, an engaging intellectual pursuit which can even be fun.

Although the stakes are higher, the same applies in medicine.  An intern faced with clinical uncertainty shares my erstwhile self-doubt as a beginning computer programmer.  Is my uncertainty humiliating?  A sign of failure?  Will I ever figure it out?  With more experience comes confidence that uncertainty isn't psychologically threatening.  It's an intellectually engaging puzzle, often with a gratifying emotional reward at the end.  In specialties such as primary care and psychiatry, uncertainty becomes the norm.  We get used to it, expect it; we realize it doesn't tarnish us individually.

An additional factor that may sound esoteric but is crucial to thriving in uncertainty is the flow state.  Variously described as being "in the zone" in sports, "centered" in Eastern meditative and martial arts practices, and "in the groove" in musical performance, this is a mental state of heightened awareness, engagement, and creativity accompanied by a relative lack of self-consciousness and conscious intent.  Whether in extreme sports, music improvisation, video gaming, or academic brainstorming, moment-by-moment uncertainty is less disruptive and feels more welcome in the flow state.  Although uncommon in typical medical practice, the flow state can arise during intimate discussion with a patient, during research activities, and when intensely absorbed in medical work-up or treatment planning — the very times when clinical uncertainty is actively addressed.

Peers are a good source of emotional support whatever one's level of expertise.  Seeing that a problem is inherently difficult is reassuring; its apparent difficulty does not reflect on oneself.  Social interaction bolsters self-esteem, and often humor is shared to defuse fear and anxiety.  Similar challenges shared by others promote camaraderie and a sense of being "all in the same boat."  And tales of challenges successfully overcome can instill optimism, and sometimes offer practical solutions for the problem at hand.

My own experience with psychiatric supervision is hierarchical, not peer-to-peer.  Supervisors model a great deal non-verbally and often unintentionally: our attitudes toward patients and their issues, the focus of clinical attention, our approach to formulating cases, levels of formality and informality, and so on.  The supervisor's engagement with clinical uncertainty is one such factor, sometimes discussed explicitly, more often modeled non-verbally.  Ideally, this role-modeling inspires and encourages supervisees to nurture clinical curiosity, and to avoid frantic efforts to resolve uncertainty with premature conclusions.

Having not read the Sommers/Launer book, I cannot comment on their rationale for "collaborative engagement with case-based uncertainty in the setting of small groups of clinicians."  Psychologically, such collaboration is apt to confer the benefits of peer support mentioned above.  In addition, it is often more fun and energizing to work as a team, although teamwork can be frustrating at times too.  As a practical matter, putting multiple brains to the task may resolve clinical uncertainties more quickly and/or accurately compared to a practitioner working alone.  Alternative tactics for resolving clinical uncertainty include consulting with recognized experts and conducting literature searches.

In my experience, psychiatrists manage clinical uncertainty by accepting that uncertainty is inherent in the field.  It is therefore not a source of shame or a sign of personal inadequacy.  Released from these emotional burdens, we are free to be curious, to keep an open mind, and to enjoy uncertainty as a puzzle to be solved, an engaging intellectual challenge.  Relatively unstructured dialog in psychotherapy may particularly induce flow states in both participants, with enhanced capacity to accept and work with uncertainty during the hour.  And finally, while many office-based psychiatrists practice individually, social support from peers, supervisors, and treatment teams can enhance comfort with clinical uncertainty.  I have every reason to believe the same holds true in primary care.

Psychiatric uncertainty and the neurobiological buzzword

brain-mriA few years ago I wrote that uncertainty is inevitable in psychiatry.  We literally don't know the pathogenesis of any psychiatric disorder.  Historically, when the etiology of abnormal behavior became known, the disease was no longer considered psychiatric.  Thus, neurosyphilis and myxedema went to internal medicine; seizures, multiple sclerosis, Parkinson's, and many other formerly psychiatric conditions went to neurology; brain tumors and hemorrhages went to neurosurgery; and so forth.  This leaves psychiatry with the remainder: all the behavioral conditions of unknown etiology.  Looking to the future, my fervent hope that researchers will soon discover causes and definitive cures for schizophrenia, bipolar disorder, and other psychiatric disorders comes with the expectation that these conditions will then leave psychiatry for other specialties.  We will always deal with what is left.  At minimum we psychiatrists should accept this reality about our chosen field.  After all, there appears to be no alternative.  Some of us go beyond this to embrace uncertainty as intellectually attractive.  We like that the field is unsettled, in flux, alive. Yet many of us clutch at illusory certainty.  Decades ago, psychoanalysis purportedly held the keys to unlock the mysteries of the mind.  It later lost favor when many conditions, particularly the most severe, were unaffected by this lengthy, expensive treatment.  Now the buzzword is that psychiatric disorders are "neurobiological."  This is said in a tone that implies we know more than we do, that we understand psychiatric etiology.  It's a bluff.

Patients are told they suffer a "chemical imbalance" in the brain, when none has ever been shown.  Rapid advances in brain imaging and genetics have yielded an avalanche of findings that may well bring us closer to understanding the causes of mental disorders.  But they haven't done so yet — a sad fact obscured by popular and professional rhetoric.  In particular, functional brain imaging (e.g., fMRI) fascinates brain scientists and the public alike.  We can now see, in dramatic three-dimensional colorful computer graphics, how different regions of the living brain "light up," that is, vary in metabolic activity.  Population studies reveal systematic differences in patients with specific psychiatric disorders as compared to normals.  Don't such images prove that psychiatric disorders are neurobiological brain diseases?

Not quite.  Readers of these exciting reports often overlook two crucial facts.  First, these metabolic differences only appear in group studies and cannot be used to diagnose individual patients.  As of this writing there is no lab test or brain scan to diagnose any psychiatric disorder.  Attempting to do so would be like diagnosing malnutrition based on height.  While malnourished people are shorter than the well-nourished on average, there is wide overlap and height is not diagnostic.  Second, etiology — the cause of these differences in brain function — remains unknown.  Differences in brain function (and structure) are not necessarily inborn.  Brain anatomy can change as a result of life experience, and metabolic activity (function) from experimental manipulation of cognitive effort, induced mood, guided imagery, etc.  Just as multiple factors affect a subject's height, multiple biological and psychological factors affect brain findings as well.  Thus, learning that patients with borderline personality show decreased metabolism in the frontal lobes (hypofrontality) is neither surprising nor indicative of a neurobiological etiology.  We already know the frontal lobes inhibit impulsive activity, and we already know borderline personality is characterized by impulsivity.  What else would we expect?

Genetic studies consistently show both heritable and environmental factors at play in psychiatric disorders.  Since the 1960s, psychiatry has called this combination the diathesis-stress model: an inborn predisposition meets an environmental stress, leading to an overt disorder.  The model helped shift the field from "nature versus nurture" to "nature and nurture" — and no research discovery or neurobiological rhetoric so far has shifted it back.  Patients and their doctors still contend with diathesis and stress: recreational drug use tips one patient into psychosis, sudden abandonment tips another into borderline rage.  Indeed, clinicians remain much more able to influence stress than diathesis.  A dispassionate assessment of what we currently know should lead to humble agnosticism about psychiatric etiology.  Genetics, biology, and environment all play a role, but beyond that there isn't much we can say.  This is why all current psychiatric medications treat symptoms and are not curative.

In this light, the popularity and zeal of neurobiological language is startling.   The American Psychiatric Association (APA) subtly changed the wording in its new Diagnostic and Statistical Manual, DSM-5, to imply that all psychiatric conditions are biological in nature.  The National Institute of Mental Health (NIMH) assumes that "Mental disorders are biological disorders...."  The National Alliance on Mental Illness (NAMI) says, "A mental illness is a medical condition...."

A more ground-level version is expressed by editor-in-chief Henry A. Nasrallah, MD in the latest edition of Current Psychiatry.  In an editorial not-so-subtly titled, "Borderline personality disorder is a heritable brain disease," Dr. Nasrallah proclaims BPD a "neurobiological illness" and "a serious, disabling brain disorder, not simply an aberration of personality" — as though these were distinct alternatives rather than two terms for the same thing.  After citing a number of biological findings which fail to prove etiology (e.g., the hypofrontality mentioned above) and which show partial heritability, Dr. Nasrallah concludes that "the neuropsychiatric basis of BPD must guide treatment."

Of course, it already does.  We already treat borderline personality disorder the best we know how, with psychotherapy (shown by functional imaging to modify brain metabolism, by the way) and often with adjunctive medication to treat symptoms.  What more do breathless declarations of brain disease buy us, other than reduced credibility?  It's not as though any of us currently withhold neurobiological treatment as a result of outmoded ideology.  On the contrary, the moment the FDA approves a cure for borderline personality disorder based on an established neurobiological etiology, I will gladly refer my patients to the neurologist, virologist, or genetic counselor who would thereafter treat such patients.

The APA annual meeting: a photo essay

MosconeCenterAs posted previously, last month I attended the American Psychiatric Association's (APA's) annual conference.  Straying from my usual format, I thought I'd post pictures from the meeting and, of course, offer comments. The meeting took place in Moscone Center, a conference center complex located just south of Market Street in downtown San Francisco.  Depicted here are anti-psychiatry protesters who held a rally in front of the main entrance at noon on the first day.  There was also an exhibit of psychiatry's cruelties (psychosurgery, shock treatment, inhumane conditions in asylums, etc) running all five days in a tent across the street from the conference.  GamelanConcert The conference was also a block from Yerba Buena Gardens, where I caught a very pleasant Balinese gamelan concert at the same time as the protest rally. This simultaneity — two events scheduled to coincide, forcing a choice — was a constant in the conference as well. The "scientific program" consisted of  numerous overlapping talks, such that attending any presentation meant missing five or more other good ones.  I'm not sure why the APA opted for such frustrating redundancy.  Nor can I explain why predictably popular talks were scheduled into small rooms, with the result that dozens of registrants were turned away once the room filled.  For instance, the crowd for Otto Kernberg's psychoanalytic talk on love and aggression was several times larger than the assigned room.KernbergAt APA  In this unusual case we were all moved to a cavernous hall at the last moment, where Dr. Kernberg gave a warm and very engaging presentation on the necessity and creative consequences of aggression in romantic love.  (I like how this photo depicts the renowned psychoanalyst Kernberg representing the APA in an era of biological ascendancy.)

The same huge auditorium was to hold the keynote address by Bill Clinton.  However, Mr. Clinton was ill and could not be there in person.  Several hundred (a couple thousand?) conference-goers nonetheless waited over an hour to see him on video.  Mr. Clinton was pleasant, thoughtful, and charismatic, but didn't offer much specifically about psychiatry or mental health.ClintonCrowd  Mostly he spoke about public health needs in general.

I didn't take many photos in the talks themselves.  Officially it was forbidden, although this rule was routinely ignored by attendees.  The quality of the presentations was high — I mostly chose "mainstream" ones this time, not the many off-beat and generally smaller meetings.  I attended presentations on suicide, personality disorders, PTSD, sexual compulsions, DSM-5 and mood disorders, the controversy over antidepressant efficacy, psychiatrists writing and blogging for the general public, teaching psychotherapy to residents, and assessing the capacity of demented patients to make medical decisions for themselves.  There were dozens of others I would have liked to attend, had they not coincided with the ones I chose.

I skipped the industry-sponsored, free lunch or dinner, non-CME presentations.  But I did wander through the exhibit hall, both to see the "new investigator" scientific posters, and to peruse the brand-new DSM-5. In contrast to the last time I went to this conference, the industry booths seemed less garish and "over the top."APAexhibits  Of course, there were still a lot of them.  Several had raffles where valuable prizes such as an iPad Mini could be won by those who gave the company their contact information.  One booth offered a pocket digest of the new DSM-5, MSRP about $60, to everyone who watched a 12 minute presentation and coughed up a mailing address.  I was tempted... but no.  (It's interesting to ponder how much a single psychiatrist contact is worth to a drug company.  Much more than $60, I'd venture.)

The DSM-5 itself is $200 in hardcover, $150 in paperback — an unabashed moneymaker for the APA.  Despite the incredible controversy it stirred up, my impression is that the changes from DSM-IV-TR are relatively minor.  In particular, the personality disorder section hasn't changed much, although the new edition is no longer multi-axial, i.e., there is no "Axis 2".  Some language has been made more precise, as well as more "biological" in some passages, and some disorders have been expanded to include more that would previously have been considered normal.  Whether this is good or bad depends on one's perspective in several respects; mostly I find it unfortunate.  DSM classifications often matter more to insurers and disability officers than to practicing psychiatrists, who in David Brooks' words are "heroes of uncertainty" (echoing an earlier post of mine, but I'll forgive him for not quoting me).  We deal with individuals, not disease categories.NoAveragePatient

I will end with a slide from the talk on antidepressant efficacy that summarizes this tension in my field.  As I've discussed previously, randomized controlled trials (RCTs) are the gold standard for scientific rigor in psychiatry; however, a lot of psychiatry is not scientific in this sense.  DSM categories help define the "average" patient with a particular disorder, leaving a lot of wiggle room since the categories are not based on etiology.  RCTs say which treatments best help this "average" patient, represented by the computer composite in the center of this slide.  However, I don't see "average" patients,  I see one of the 12 individuals who contributed to the composite.  Thus, for me, the new DSM was a sideshow at the conference.  The most insightful presentations, whether on PTSD, suicide, or capacity assessment, combined science and the nuanced human communication of meaning.  They recognized that our work is informed by science but goes well beyond it.  Anti-psychiatrists don't like this, insurers don't like this, neuroscientists don't like this, even many psychiatrists don't like this.  But it's true and inevitable for the foreseeable future.  I like it.  As for the APA annual meeting, I'm glad I went, and equally glad I won't feel the need to go back for several years at least.

Polypharmacy — Sloppy thinking in psychiatry 2

My second post in this series on sloppy thinking in psychiatry is devoted to polypharmacy, the medical term for prescribing multiple medications at once, especially for the same problem.  Polypharmacy is at best a risk thoughtfully taken because nothing simpler and safer will do.  At worst it's a dangerous error, exposing patients to unnecessary hazards purely as a result of laziness and sloppy thinking by their doctors.  Unfortunately, the latter is all too common in psychiatry.  Let's look at why. It has been said that the less we know about an illness, the more treatments we have for it.  Instead of one definitive cure that attacks the root of the problem, various remedies ease symptoms — not the cause — often via different mechanisms.  A good example of a definitive cure is a specific antibiotic to treat a bladder infection.  We know how bacterial infections work, and we have antibiotics to attack the root of the problem.  Ancillary treatments for fever or pain are sometimes used, but they are clearly secondary, and often optional.  In contrast, the pathogenesis of psychiatric disorders is not known, thus we have no treatments to attack the roots of these problems.  For example, antidepressants affect neurotransmitters that appear implicated in depression, but the exact way these neurotransmitters relate to the syndrome of depression is unknown.  Thanks to our ignorance, we have medications that affect serotonin, and others that affect norepinephrine and/or dopamine.  In recent years atypical neuroleptics (antipsychotics) have been approved as add-ons for treating depression, a worrisome development given their risks.

Since we don't have a definitive cure for depression, many patients report partial (or minimal) improvement from any one medication.  The prescriber may then add another on the theory that it may help via a different chemical mechanism — a theory that is difficult to confirm or refute, as we don't know the mechanism in the first place.  The original medication is not stopped: If the patient improves, why disrupt a winning combination?  And if the patient doesn't improve, we wouldn't want to withhold an antidepressant from a depressed person, would we?  Sloppy thinking all around, yet sadly common.

Similar arguments can be made for the treatment of bipolar disorder and schizophrenia.  Lacking a true understanding of pathogenesis, we treat empirically.  And empiric treatment, while often compassionate and necessary and helpful, invites the shaky logic of adding more medications hoping for more empiric benefit.

Compounding and worsening this situation is psychiatry's abandonment of parsimony in diagnosis and clinical assessment over the past 30 years.  Prior to the publication of DSM-III in 1980, psychiatric evaluation was an attempt to explain a patient's seemingly unrelated complaints using a single theory (often psychoanalytic, but possibly biological or even behavioral).  The introduction of phenomenological diagnosis in DSM-III encouraged multiple diagnoses in the same patient, say Major Depression and PTSD on Axis I, and a personality disorder on Axis II.  There was no longer any attempt to tie it all together.  This has encouraged a piecemeal approach to treatment: a medication for depression, a different one for PTSD, maybe something for sleep, and something else again for agitation due to the personality disorder.  That's four different psychiatric medications already, and we've hardly even started.  Patients with personality disorders often complain of "mood swings," so let's add a mood stabilizer like lithium or Depakote.  And they're anxious, so we could add a benzodiazepine tranquilizer like Ativan, or a beta-blocker like propranolol, or an atypical neuroleptic.  Or what the hell, all three!  We're up to seven or eight medications now, and we haven't even considered a stimulant for their ADHD — because, after all, the patient is having trouble concentrating... funny how it was never diagnosed before.  And we haven't augmented the antidepressant with thyroid supplementation, nor have we added a second antidepressant...

While 10+ psychiatric medications is clearly over top, I've evaluated a number of patients who arrive on six, often an (1) antidepressant, (2) mood stabilizer, (3) tranquilizer, (4) sleep aid, (5) stimulant, and (6) another antidepressant or mood stabilizer.  Almost without exception, I've been able to cut this list in half, and in some cases down to zero, or more often, one medication.  It's less a matter of expert medication choice, and more an aversion to sloppy thinking.  According to one study, antipsychotic polypharmacy can be simplified without harm 2/3 of the time.

Psychiatric polypharmacy is often intellectually lazy.  Needless to say, there are far more drug combinations than there are studies assessing the risks and benefits of these combinations.  Polypharmacy is nearly always an educated guess, not "evidence based medicine."  It's not even good single-case research, where one would ideally change a single variable at a time.  All too often, medications are added to treat the side-effects of other medications, as with "ADHD" in the case above, a tail-chasing exercise that only gets worse over time.  With every added medication there are added side-effects, and sometimes adverse interactions that can be more harmful than the original problem.  In my experience, generic side-effects such as weight gain and cloudy thinking are more the rule than the exception in patients taking multiple psychiatric medications.  It should happen a lot less than it does.
