A Kinder, Gentler ECT
by the Riverfront Times
1997
"Something bent down and took hold of me and
shook me like the end of the world," wrote
Sylvia Plath in The Bell Jar. "Whee-ee-ee-ee-ee,
it shrilled, through an air crackling with blue
light, and with each flash a great jolt drubbed
me until I thought my bones would break and the
sap fly out of me like a split plant."
That's what shock therapy used to be.
Today, anesthesia, muscle relaxants,
re-engineered machines and repositioned
electrodes buffer the jolt, and insights about
the biochemistry of depression ease the stigma.
As a result, electroconvulsion therapy (ECT) is
being used more readily and more successfully,
even on older adults once considered high risk.
Not only does ECT work when drugs can't, but it
efficiently short-circuits psychiatric-hospital
stays, making it a natural in a cost-conscious
managed-care climate.
The improvements are dramatic -- but
not everything has changed. Patients still
complain of permanent, significant memory loss,
and psychiatrists still say they're wrong.
Researchers still don't know exactly how ECT
works or what it might do to a child's
developing brain. Ethicists still don't know how
to tell if a patient's consent was really
"informed." And the Food and Drug Administration
(FDA) still hasn't asked for clinical trials
showing that individual ECT machines are safe.
Used to people recoiling at the very
notion of electrically induced brain seizures,
ECT experts tend to minimize concerns, afraid
another swing of the pendulum could deprive
patients of their last alternative. But after
struggling so valiantly to reclaim ECT's
reputation, psychiatrists' own memories may have
grown a little spotty when it comes to the need
for caution.
Ugo Cerletti and Lucio Bini first used shock
therapy in Italy in 1938, convinced the body
manufactured a "vitalizing substance" during an
epileptic convulsion. They watched breathlessly,
Cerletti wrote later, "overwhelmed during the
apnea as we watched the cadaverous cyanosis of
the patient's face." No substance oozed, but the
shock did snap the man into lucidity.
In the bedlam of the '40s and '50s,
shock was the only tool psychiatrists had, and
they administered it with abandon. The typical
recipient was a 40-ish male, impoverished and
rebellious, living in a public institution. By
the end of the '50s, enough asylums had zapped
patients with a rainbow of disorders into
monochrome docility, and public outrage grounded
ECT. Just in time, miraculous new anti-psychotic
and anti-depressant medications took over.
It took another few decades to realize
the drugs' less than miraculous side effects --
cardiac risks and mobility disorders -- and the
plain fact that they didn't help everyone.
Meanwhile, ECT had been significantly improved.
Learning that seizure thresholds varied
enormously, psychiatrists found they needed only
a fraction of the standard voltage for many
women and young people. Sedatives and muscle
relaxants removed the pain, the need for
restraints, the physical danger of broken limbs
and the horrific twitching spasms. Patients were
thoroughly monitored, and physical resistance
(some people do have thicker skulls) was
measured ahead of time to avoid electrical
burns.
When Malcolm Bliss closed, Dr. John
Csernansky, medical director of the Metropolitan
Psychiatric Center that replaced it, retrieved a
little black box from the basement -- a shock
machine from the 1940s. Now, holding it in one
hand, he presses its silver button urgently,
demonstrating how the psychiatrist controlled
the electrical pulse's duration. Crudely
measured, those pulses lasted one or two seconds
apiece, and continued as long as the doctor
chose. In today's machines, the electricity is
produced from a different kind of wave, the
duration of each shock is computerized, each
pulse lasts perhaps 0.5 milliseconds, and the
entire train of impulses cannot last longer than
eight seconds.
An American Psychiatric Association
(APA) task force issued guidelines in 1990
suggesting that hospitals "insulate the waiting
patient from auditory and visual contact with
the treatment and recovery areas" -- so he no
longer has to watch peers emerge from treatment,
their eyes deadened. The guidelines also note
that "immediate side effects from ECT are rare
except for headaches, muscle ache or soreness,
nausea and confusion."
Compared to the old days, it's a
picnic.
Almost all St. Louis hospitals provide ECT
treatment. "We do maybe 10 a day," says one
anesthesiologist. "Everybody's doing them. It's
very well accepted in the medical community."
St. John's Mercy Hospital counted more than
2,000 treatments given in the last fiscal year
(compared to 1,500 five years ago). Dr. Donald
Hay, director of the mood-disorders program at
St. Louis University, says they do 10 treatments
a week on average. BJC Inc., known as the local
ECT headquarters, declined to provide a count.
But even satisfied patients call Barnes "Jiffy
Jolt" because it speeds so many of them through
its ECT assembly line.
The nickname isn't surprising: Harvard
researchers announced last year that ECT's
popularity increases around academic medical
centers. Universities are supposed to take the
lead, after all, and depression is the disease
of the decade. In 1990, the National Institute
of Mental Health estimated a startling 9.5
percent of American adults (17.5 million people)
suffering from depressive disorders. Now that we
know depression is often biological, there's
less shame, more determination to get relief.
And after successful ECT, improvement's
intuitively obvious.
"Somehow I just knew that I was
better," people say, "and that I did not have to
be in the hospital anymore." Major depression
isn't the blues, they add; it's hell, eroding
love, joy, energy, will, clarity and the very
instinct for life. When Anne Simpson (a
pseudonym) sank into deep depression, "it went
on for months, and the part of me that was
willing to continue on felt as though it were
getting smaller and smaller." Doctors tried a
buffet line of drugs; none worked. But after her
third course of ECT, Simpson renewed
friendships, changed jobs, re-entered the world.
Fran Scott has had ECT twice in her life, when
manic-depression hit a wall no drug could
penetrate, and she'd do it again. "A lot of
people just go in the hospital and sit there
while doctors play games with drugs," she
explains, "and they are still miserable. And
it's scary to be depressed."
Scientists still don't know exactly why ECT
works -- except that it has less to do with
electrical jolts than with the seizure they
induce. Electricity runs through our brains
already; that's what causes the neurons to fire
and discharge neurotransmitters, which then
carry the impulse across the great divide to the
next cell. "Brain cells are set up in
oscillating circuits that are firing regularly,"
explains Csernansky. "What you are trying to do
when you induce a seizure is get them all to
fire in synchrony."
Many psychiatrists believe an ECT
seizure increases the brain's sensitivity to the
neurotransmitter serotonin, which meshes
perfectly with the theory that low levels of
serotonin cause depression. Another theory is
that ECT, which, paradoxically, raises the
brain's seizure threshold, causes an
anti-convulsive effect that may also involve
serotonin.
ECT can temporarily help catatonic,
manic and other psychotic states, but it's used
most often for severe depression whose cause is
biological. "What ECT cannot do," underscores
Metropolitan's new ECT director, Dr. Omar
Quadri, "is change the real-life situation of
the person." Psychiatrists say patients who
respond best to ECT have depression that shows
up physically, in disrupted sleep, appetite,
energy, sex drive, etc. But Debbie Kuhn, a
social worker who co-founded the Women's
Counseling Collective, points out that
biological and situational depression aren't
that easy to divide. Emotional problems often
bubble up as physical symptoms, and what looks
biological can have complex underlying causes.
Misdiagnose, and you're needlessly subjecting
someone to the anesthesia, expense,
disorientation, stigma and possible memory loss
of ECT -- not to mention the despair that hits
when the "treatment of last resort" has failed.
Or keeps failing. "I've seen people
who were not responding to medication," says a
former psychiatric patient, "and the ECT didn't
work, and they'd just keep giving it and giving
it." There's more than sadism at work;
apparently the seizures have to reach some
critical unknown number. "There was actually a
movement at one time to do multiple seizures
within a single treatment," Csernansky recalls.
"In principle, it sounded like a good idea."
ECT machines, in use long before the 1976
Medical Device Act, were grandfathered into FDA
approval without rigorous review. They are Class
III, and normally manufacturers would have had
to submit clinical trials documenting their
safety by now. Instead, they applied for a
reclassification to Class II, explains FDA
physiologist Steve Hinckley. "We are trying to
decide how we want to approach the
reclassification," he adds, "and that should be
addressed in the near future." Currently,
manufacturers need provide only a technical
comparison of their machine to a similar
product. No ongoing inspections are required; a
hospital could be using an ancient high-voltage
machine without violating a single rule.
Hinckley says the FDA would only look twice if a
pattern started showing up, "like suddenly a lot
of Chevys with the brakes failing."
Rep. Peter DeFazio (D-Ore.) has
repeatedly demanded governmental review of ECT;
the federal Department of Health and Human
Services (HHS) finally acceded, but DeFazio was
recently informed that they have subcontracted
that review to a private nonprofit organization.
David Oaks, director of the Support Coalition
(an alliance of 44 groups working for human
rights in psychiatry), says the review proposal
is so vague it doesn't even mention ECT.
Dr. Harold Sackeim, professor of
psychiatry at Columbia University and consultant
to the APA's task force on ECT, calls U.S.
machines markedly superior in safety. He says,
"At a purely technical level, there's been a
misunderstanding or misrepresentation. ECT's
opponents claim that, because anesthesia is
used, more electricity is required. What isn't
appreciated is that the nature of the wave form
used now is far more efficient, so on average
you need about a third less electricity."
The debate blurs into a general lack
of consensus -- a Harvard study in the June 1995
American Journal of Psychiatry reported "marked
disagreement" among clinicians about the value,
proper use and timing of ECT. The research is
rife with contradictory results and conflicts of
interest. The standard textbook on ECT was
written by Dr. Richard Abrams, who happens to
co-own Somatics Inc., one of the world's largest
ECT-machine companies. One of ECT's strongest
advocates is APA task-force member Dr. Max Fink,
a paid consultant on ECT lawsuits who's been
receiving video royalties from an ECT-machine
company. Csernansky isn't worried about such
conflicts -- an ECT machine is hardly an
"impulse purchase," he points out. Still, the
experts do stand to gain.
According to the APA's model consent form,
perhaps one in 200 patients reports devastating
memory losses. That stat has been vigorously
challenged by activists, and APA consultant
Sackeim admits "it's hard to defend
quantitatively." What was accurate, he says, was
the intent, which was to emphasize the
infrequency of severe memory problems with
today's ECT.
Anne Simpson had three courses of ECT
last year, and a lot of memory loss. "The
standard line I would get from my psychiatrist
was, `That isn't in the literature,'" she says
wryly. "But everyone I know who's had ECT has
had problems with memory. I think psychiatrists
really underplay the side effects. I had
cognitive problems, I was physically wasted,
exhausted all the time. And most of 1995 is
gone.
"After you recover from depression,
people encourage you to rebuild your life," she
adds. "But frankly, I couldn't even remember
what my life was. I run into people I met in '95
and have no recollection of who they are.
Journals I kept at the time are completely
unfamiliar. And I'm still finding clothes I
don't recognize." She'd been depressed before,
she says, but never experienced this kind of
memory problem. "I consider myself a proponent
of ECT, but I strongly feel people are not given
full information."
In lawsuit after lawsuit,
psychiatrists have blamed the mental illness
itself -- and not the ECT -- for the memory
loss. Neuropsychological deterioration results
from some of the disorders for which ECT is
used, they say, and as for mood disorders, mood
is the best predictor of how anyone evaluates
his or her memory. If we're sad, we feel like
we're forgetting more.
In patients' accounts, though, memory
problems don't explain themselves away that
readily. "The nurse kidded me because I kept
asking her, `Why am I getting a divorce?'"
laughs Ellen Fein, "but it was brand new to me."
Scott doesn't remember "going to the doctor,
going in the hospital, the treatments, the day
in between. Except smoking -- I remember being
out on the smoking porch! But I don't remember
the month of May." She's told her depression
started after she found a sofa and couldn't get
it to her home. "I don't even know why I was
looking for a sofa," she chuckles, "or where I
got the money."
Psychiatrists make much of the shift
to unilateral ECT, which is given only on the
"nondominant" side of the brain and thus leaves
verbal memory unscathed. Unilateral ECT is
recommended whenever possible (although
clinicians do murmur that bilateral still causes
a better seizure). In Toxic Psychiatry, Dr.
Peter Breggin names the downside of the
improvement: "It's relatively easier for doctors
to overlook harm done to the nonverbal side,
because the patient can't speak about it."
Maybe people who feel they were
pressured into ECT have such a sense of loss and
outrage, they cling to illusions of impaired
memory. But there are other possibilities: That
it's easier to call someone with mental illness
"treatment-resistant" than to credit her claims.
That standardized tests can fail to detect
subtle memory problems. That psychiatrists don't
want to emphasize the memory problems of an
80-percent-effective treatment that's often used
as a last resort.
Sackeim does admit, "If you are
engaged in a physical treatment that is altering
neuropsychological function, there will be
exceptional, very rare cases where there are
untoward effects." Even a generally favorable
National Institute of Health consensus report
(1985) conceded the risk of permanent memory
loss with ECT. But Quadri, about to head a new
ECT program, insists that "the memory loss is
not permanent. If it happens at all, it's
usually transient and very minor. Not major
chunks of their life -- that does not happen."
Tell that to the psychiatrist who
drove round and round her own neighborhood, the
woman who didn't remember being president of a
self-help center, the woman who couldn't find
her shower. "She probably remembered it that
night," remarks a St. Louis anesthesiologist who
asked not to be named. "I don't think the memory
problems are that profound." His dismissal
sounds cavalier until he continues, his voice
taut: "You have to know what these people look
like. Usually they are chronically depressed,
they have the flattest affect (emotional
expression) you have ever seen, and they're
leading pretty dysfunctional lives. To see them
starting to come in and actually have a
conversation ..." To a witness, that change is
worth a few memories.
Today's typical ECT patient is a privately
hospitalized older white woman who's clinically
depressed, can't be helped by medication and has
insurance. That shift alone worries ECT's
opponents. "An older woman who is sad, isolated
and pressured by her family will sign almost
anything," Oaks warns. "It's not consent, it's
elder abuse! If we were dealing with gutter
repair and how the elderly are being ripped off,
60 Minutes would be there in a flash."
Psychiatrists counter with the
benefits: ECT is fast, it works when drugs can't
and at least 80 percent of the time it breaks
the impasse. Would you deny healing to someone
you love just because, at the point of decision,
she's too sick to say yes? In ECT cases, logical
guidelines for informed consent spin into
paradox: How do you set criteria when, in Hay's
wry summary, "The organ that makes the decision
is the organ affected"?
Missouri law allows a guardian or
court to order ECT for someone who is too
deluded to decide or too depressed to think
anything could help. "We have to have a lot of
paperwork to back up a request for court order,"
notes Dr. Peggy Szwabo, assistant professor of
psychiatry at St. Louis University. "Anytime we
go to court, all of us get nervous. But if
someone is a danger to themselves or others, you
are going to do the hard work."
The law presumes every individual
competent until proven otherwise, and the APA
guidelines say that "the presence of psychosis,
irrational thinking, or involuntary
hospitalization do not in themselves constitute
proof of lack of capacity." To a layperson, the
statement sounds ludicrous: Since when do
psychosis and irrationality make for good
decisions? Quadri offers a crisp reminder that
"psychosis is not global. A patient may believe
someone is coming to kill them, but they don't
stop knowing food is good." (If a patient
consented saying, "Great, the electricity will
suck the evil spirits from my mind," their
capacity would be questioned; psychosis twisted
its way into the decision.)
The APA guidelines warn that "threats
of involuntary hospitalization or precipitous
discharge" violate someone's informed consent.
Then they say patients have the right to know
the consequences of their decisions, and
physicians have the right to transfer a patient
if they disagree with the chosen course of
treatment. So how do you, nonthreateningly, tell
someone who's severely depressed that she may
kill herself without ECT, and if she refuses ECT
you will have to stop treating her and she will
have to leave the hospital?
"We always try to be matter-of-fact,"
comments Csernansky. "We say, `Well, we think
you would benefit from ECT. Yes, there are
alternatives, we could try drug therapy, but it
would take longer.' We're not threatening them,
but we are advising them." Unfortunately,
whether someone hears threat or advice will
depend on their mood, past experiences and
hundreds of other unknowable variables. Private
hospitals have an even tougher scenario because
money dictates the time frame. "We're in a
relatively cleaner position," notes Csernansky,
"because we can continue treating patients
whether they can pay or not."
Most of the ECT recipients The
Riverfront Times spoke with did give consent --
sort of. "Really, I didn't know it was up to the
person," confides Scott. "I mean, I realize I
probably signed a consent form, but I didn't
realize it was up to me." Ellen Fein, normally
her own sharpest advocate, says, "I don't really
remember giving an OK. I was at a point where I
felt like I'd tried everything, and I trusted my
doctors."
Short of telepathy, there's no way to
clarify consent proceedings. So maybe we need to
be a little franker about their limitations.
"If someone is ill enough to be admitted to the
hospital," notes Csernansky, "which is getting
harder and harder to prove, there is tremendous
pressure to treat their illness as quickly as
possible." ECT can cost as much as $800 per
treatment; it requires six to eight treatments
on average, and lasts two or three weeks. But
drug and/or psychotherapy treatment can take
considerably longer, and the least expensive
psychiatric hospital, the state-funded
Metropolitan, costs about $400 a day. "If ECT
decreases length of stay," sums up Quadri, "they
will promote it."
As for outpatient ECT, when Dr.
Michael J. Bennett, vice president of Merit
Behavioral Care, attended a meeting of the APA's
new task force on ECT, he found medicine and
insurance in rare agreement. At St. John's
Mercy, outpatients and inpatients are already
split 60-40, and the trend's increasing
everywhere. It's great for patients with
supportive families to sleep in their own bed --
but what about people who live alone, or who
drive in from a rural area three days a week,
exhausted and disoriented?
The allegation that doctors make money
off ECT is more flurry than fact, although it's
true that insurance companies reimburse at a
higher rate for ECT than for psychotherapy or
drug checks. "ECT tends to be self-regulated,"
says Csernansky, "because people who do it, do a
lot of it. They pay higher insurance premiums,
so ..." We'll say it: They need to justify the
expense.
At the Women's Counseling Collective,
Kuhn says she had six patients hospitalized last
year, and every one was offered ECT. "I've had
clients actually told, `This is the only
treatment that will help you,'" she adds. "Or
given ECT without the therapist or
(primary-care) physician being consulted. My
concern is the increase: For a while, hospitals
began to offer more comprehensive treatment,
with chemical-dependency and sexual-trauma
units, family programs, therapy, medications.
Now, with the rise of managed care, we help
people by giving them a pill or shocking them.
Heaven forbid we talk to them about their
lives."
Last December, Dennis Cauchon wrote a
cover story for USA Today quoting an assertion
that in Texas (one of only four states with ECT
reporting laws), 65-year-olds got 360 percent
more shock therapy than 64-year-olds. There,
Medicare made the difference. In St. Louis,
there's no way to know. Our Medicare B carrier,
General American, also reimburses for ECT, but
it doesn't track the number of treatments
separately, and neither does the state of
Missouri.
Activists warn that, based on Texas'
stats, the elderly's rate of death after ECT
could be 50 times higher than the 1 in 10,000
estimated on the APA model consent form. But Hay
points out that elderly patients are often
referred very late (people expect the old to be
depressed) and have serious medical conditions
(often that's why they're receiving ECT instead
of drugs with cardiac side effects).
Researchers do agree that the risk of
severe confusion and heart and lung problems
after ECT increases with age. So does the
seizure threshold, which means it's harder to
induce a seizure long enough to have the desired
effect. So why is ECT being used more and more
with older patients? Because medication risks
also increase with age, as does the
vulnerability to severe depression. Older
people's psychic reserves are depleted from all
sides -- by physical aging, by decreases in
neurotransmitter levels, by losses and
loneliness.
At the other end of life's spectrum,
children carry even higher risk. Precious little
is known about mood disorders in a developing
brain. (Psychiatrists used to think children
couldn't get depressed because they weren't
mature enough to feel guilt. Biochemical
discoveries exploded that cozy notion, but
insight hasn't filled the void.) Dr. Tony Baker
published an article in the British medical
journal Lancet last year recommending a halt to
treatments of children, whose skulls have lower
electrical resistance. In the U.S., only Texas
and California prohibit ECT on children younger
than 16. What's most frightening is the
inescapable logic: We won't know how to do it
safely until we do it more often.
The paradoxes continue: As the World Association
of Electroshock Survivors fights to ban ECT, the
National Association of Mental Illness pushes to
make it accessible to lower-income and minority
patients. In a 1986 National Institute of Mental
Health survey, 23 percent of patients -- but
only 1.5 percent of ECT recipients -- were
African-American.
Higher-income recipients -- mostly
white and two-thirds female -- will be receiving
even more ECT in the future. Since no ECT study
has shown an effect lasting longer than a month,
and since drugs didn't work in the first place,
more psychiatrists are now recommending
"maintenance ECT," which continues treatments
for many weeks at a decreasing frequency.
"Certain patients respond only to ECT," explains
Quadri. "Maintenance ECT is like a miracle to
them."
It had better be a well-administered
miracle, though, and the APA guidelines are
streaked with uncertainty. "Criteria for
capacity to consent are vague," they admit, and
"formal `tests' of capacity do not exist." How
do you know when to use ECT? "At present no
accepted standards exist." There's also no
central tracking and no licensing; each hospital
is responsible for "privileging" psychiatrists
who, hopefully, have had specialized training.
"Unfortunately," the guidelines note, "in many
departments training in ECT has fallen behind
training in other treatment modalities."
Going futuristic, there are
frightening potential applications for ECT,
especially since, as Quadri notes, "low levels
of serotonin are linked also to impulsivity.
Impulsive suicides, aggressive homicides." Last
year, a study published in the Journal of
Forensic Sciences examined a case of involuntary
ECT that had been court-ordered in New York for
a prisoner before his trial.
The simpler future lies with
alternatives. Researchers in Spain, Israel and
New York are experimenting with magnetic
currents, which don't require anesthesia, don't
cause pain or externally obvious seizures, and
can be focused precisely. So far, benefits last
only two weeks. But as Fein points out, "There's
still no cure for mental illness."
Until there is, manipulating
electromagnetic forces and chemicals will
continue -- probably should continue -- to make
us uneasy. "Despite everything we can do, there
is something sacred about the human mind,"
Csernansky says softly. "My own view is that
there will always be a certain mystery about it
-- and some discomfort about whether it's right
to treat the mind like it's just another organ
of the body." After this sudden rush of words,
he pauses, then gestures with an open palm.
"It's a little closer to God than the liver."
