Are Psychiatric Medications Making Us Sicker?

By John Horgan
Three years ago, I was reminded in dramatic fashion of the chasm
between psychiatry and more-effective branches of medicine. My
14-year-old son, Mac, while playing lacrosse, emerged from a collision
with his right arm askew. I drove him to a local hospital, where an
orthopedic surgeon on duty immediately diagnosed the injury: dislocated
elbow. He gave Mac an oral and local anesthetic and put him in a
portable X-ray machine that showed Mac's elbow joint on a screen, in
real time. Watching the screen, the doctor quickly snapped Mac's elbow
back into place.
Overcome with gratitude to the doctor, I was leading my groggy son out
of the hospital when my cellphone rang. An old friend, whom I'll call
Phil, was on the line. He was in the psychiatric ward of a New York
hospital, to which his 16-year-old son had been committed. The boy, who
was taking antidepressants for depression, had threatened to commit
suicide, not for the first time. The doctors were recommending
electroconvulsive therapy, or ECT. Knowing that I had written about
shock therapy and other psychiatric treatments, Phil (Dave
Plunkert for The Chronicle Review)
asked my opinion. The fact that Phil had called me, a mere journalist,
for advice in such a dire situation spoke volumes about the troubles of
modern psychiatry.
I first took a close look at treatments for mental illness 15 years ago
while researching an article for Scientific American. At the time,
sales of a new class of antidepressants, selective serotonin reuptake
inhibitors, or SSRI's, were booming. The first SSRI, Prozac, had
quickly become the most widely prescribed drug in the world. Many
psychiatrists, notably Peter D. Kramer, author of the best seller
Listening to Prozac, touted SSRI's as a revolutionary advance in the
treatment of mental illness. Prozac, Kramer said in a phrase that I
hope now haunts him, could make patients "better than well."
Clinical trials told a different story. SSRI's are no more effective
than two older classes of antidepressants, tricyclics and monoamine
oxidase inhibitors. What was even more surprising to me—given the rave
reviews Prozac had received from Kramer and others—was that
antidepressants as a whole were not more effective than so-called
talking cures, whether cognitive behavioral therapy or even
old-fashioned Freudian psychoanalysis. According to some investigators,
treatments for depression and other common ailments work—if they do
work—by harnessing the placebo effect, the tendency of a patient's
expectation of improvement to become self-fulfilling. I titled my
article "Why Freud Isn't Dead." Far from defending psychoanalysis, my
point was that psychiatry has made disturbingly little progress since
the heyday of Freudian theory.
In retrospect, my critique of modern psychiatry was probably too mild.
According to Anatomy of an Epidemic (Crown Publishers, 2010), by the
journalist Robert Whitaker, psychiatry has not only failed to progress
but may now be harming many of those it purports to help. Anatomy of an
Epidemic has been ignored by most major media. I learned about it only
after Marcia Angell, former editor of The New England Journal of
Medicine and now a lecturer on public health at Harvard, reviewed the
book in The New York Review of Books in June. If Whitaker is right,
American psychiatry, in collusion with the pharmaceutical industry, is
perpetrating what may be the biggest case of iatrogenesis—harmful
medical treatment—in history.
As recently as the 1950s, Whitaker contends, the four major mental
disorders—depression, anxiety disorder, bipolar disorder, and
schizophrenia—often manifested as episodic and "self limiting"; that
is, most people simply got better over time. Severe, chronic mental
illness was viewed as relatively rare. But over the past few decades
the proportion of Americans diagnosed with mental illness has
skyrocketed. Since 1987, the percentage of the population receiving
federal disability payments for mental illness has more than doubled;
among children under the age of 18, the percentage has grown by a
factor of 35.
This epidemic has coincided, paradoxically, with a surge in
prescriptions for psychiatric drugs. Between 1985 and 2008, sales of
antidepressants and antipsychotics multiplied almost fiftyfold, to
$24.2-billion. Prescriptions for bipolar disorder and anxiety have also
swelled. One in eight Americans, including children and even toddlers,
is now taking a psychotropic medication. Whitaker acknowledges that
antidepressants and other psychiatric medications often provide
short-term relief, which explains why so many physicians and patients
believe so fervently in the drugs' benefits. But over time, Whitaker
argues, drugs make many patients sicker than they would have been if
they had never been medicated.
Whitaker compiles anecdotal and clinical evidence that when patients
stop taking SSRI's, they often experience depression more severe than
what drove them to seek treatment. A multination report by the World
Health Organization in 1998 associated long-term antidepressant usage
with a higher rather than a lower risk of long-term depression. SSRI's
cause a wide range of side effects, including insomnia, sexual
dysfunction, apathy, suicidal impulses, and mania—which may then lead
patients to be diagnosed with and treated for bipolar disorder.
Indeed, Whitaker suspects that antidepressants—as well as Ritalin and
other stimulants prescribed for attention-deficit disorder—have
catalyzed the recent spike in bipolar disorder. Though bipolar disorder
was relatively rare just a half-century ago, reported rates of it have
increased more than a hundredfold, to one in 40 adults. Side effects
attributed to lithium and other common medications for bipolar disorder
include deficits in memory, learning ability, and fine-motor skills.
Similarly, benzodiazepines such as Valium and Xanax, which are
prescribed for anxiety, are addictive; withdrawal from these sedatives
can cause effects ranging from insomnia to seizures, as well as panic
attacks.
Whitaker's analysis of treatments for schizophrenia is especially
disturbing. Antipsychotics, from Thorazine to successors like Zyprexa,
cause weight gain, physical tremors (called tardive dyskinesia) and,
according to some studies, cognitive decline and brain shrinkage.
Before the introduction of Thorazine in the 1950s, Whitaker asserts,
almost two-thirds of the patients hospitalized for an initial episode
of schizophrenia were released within a year, and most of this group
did not require subsequent hospitalization.
Over the past half-century, the rate of schizophrenia-related
disability has grown by a factor of four, and schizophrenia has come to
be seen as a largely chronic, degenerative disease. A decades-long
study by the World Health Organization found that schizophrenic
patients fared better in poor nations, such as Nigeria and India, where
antipsychotics are sparingly prescribed, than in wealthier regions such
as the United States and Europe.
A long-term study by Martin Harrow, a psychologist at the University of
Illinois College of Medicine, found an inverse correlation between
medication for schizophrenia and positive, long-term outcomes.
Beginning in the 1970s, Harrow tracked a group of 64 newly diagnosed
schizophrenics. Forty percent of the nonmedicated patients
recovered—meaning that they could become self-supporting—versus 5
percent of those who were medicated. Harrow theorized that those who
were heavily medicated were sicker to begin with, but Whitaker suggests
that the medications may be making some patients sicker.
Several possible objections to Whitaker's case against psychiatry come
to mind. First of all, as Harrow speculates, over time heavily
medicated patients may not fare as well as less-medicated patients
because the former truly are sicker. Also, the recent surge in mental
disability may stem, at least in part, from a decrease in the stigma
associated with mental illness, spurring more people to seek and obtain
treatment and government assistance. In her review, Marcia Angell
called Whitaker's book "suggestive, if not conclusive," which seems
right to me. At the very least, Whitaker's claims warrant further
investigation.
Although Whitaker doesn't address electroconvulsive therapy, its
persistence strikes me as yet another symptom of the weakness of modern
psychiatry. It fell out of favor in the 1970s, in part because of its
negative portrayal in the 1975 film One Flew Over the Cuckoo's Nest,
and yet about 100,000 Americans a year still receive ECT. Studies
suggest that the therapy can provide temporary relief from acute
depression, but virtually everyone who receives electroconvulsive
therapy relapses within a year without further treatment. Proponents
claim that ECT has few significant side effects, but this year an FDA
panel ruled that ECT should remain classified as a "high-risk"
procedure because it can cause persistent memory loss and other side
effects. If SSRI's and other psychiatric medications were truly
effective, ECT would long ago have been tossed into the dustbin of
failed psychiatric treatments.
So what happened to Phil's son? When Phil called me, I told him that if
my son were suicidally depressed, I'd resist giving him shock treatment
unless doctors convinced me there was absolutely no alternative. Phil
decided against ECT, and his son, after being released from the
hospital, gradually stopped taking antidepressants too. He still
struggles with depression, and he smokes more marijuana than Phil would
like. But he is healthy enough to be starting college this fall.
