Shock Therapy
Called `barbaric' by some, a `miracle' cure by others,
it is
being used more and more to treat depression

SUSAN WITTE remembers looking at her children and wondering when
they grew up. She recalls looking at pictures from a fun-filled vacation
and wondering when she was away. And she still wonders about her husband
. . . has it really been 23 years of marriage?
Susan Witte has lost six years of her life.
The 42-year-old North Valley Stream woman says the memories, both
good and bad, were wiped out when psychiatrists passed electric currents
through her brain to pull her from the depths of a depression.
"The doctors said that my memory would return in four weeks," Witte
said of her treatment with electroconvulsive therapy (ECT). "It just
kept getting worse. It never came back." And, she says, the treatments
did not alleviate her depression.
Thousands of patients who receive what is popularly known as shock
therapy complain of its problems, such as loss of memory. But thousands
of others swear by the treatment that has rapidly expanded to an
estimated 100,000 people a year.
Since it was discovered more than 50 years ago, ECT has split the
psychiatric community. Some doctors argue that it is a barbaric
throwback to a time when there were no drugs available to treat
depression and radical surgery, even lobotomies, were mistakenly
believed to be the only cure. Other psychiatrists contend that using
quick, high-voltage bursts of electricity is usually safer, faster and
more effective in treating suicidal depression than are most drugs.
"Some of my colleagues would rather spend years, even decades,
administering mind-altering drugs, most with disturbing side effects,
even though studies have shown that thirty percent of patients do not
respond to medications," said Dr. Max Fink of the Health Science Center
at the State University of New York at Stony Brook. An ECT expert, Fink
edits the only journal devoted to research on shock therapy.
"They still believe that there are no alternatives," the
psychiatrist said. "If any of us could find a better way to treat
patients, we would. At the present time, there is nothing that beats
ECT."
But there are equally outspoken doctors who have built their careers
on fighting shock therapy. They are armed with decades of studies that
they say prove the dangerousness of the technique.
"ECT is a barbaric assault on the brain," said Dr. Peter Breggin, a
Maryland psychiatrist who opposes the treatment. Breggin is often called
as a witness in ECT malpractice cases. "It damages the brain. ECT
patients don't know whether they are coming or going." Animal studies
clearly show that zapping the brain with electricity damages cells, he
argues.
Breggin is also one of the leading opponents of a recent task force
report by the American Psychiatric Association that backs ECT as a
primary therapy for some cases of severe depression and mania.
The report, released in December, recommends that the 29,000 U.S.
psychiatrists learn the technique and offer it as an alternative to drug
therapy. The six researchers who worked on the report concluded that ECT
was safe and effective when used appropriately. ECT, the report
concluded, "should not be seen as a `last resort' therapy. Such a view
may well deprive patients of effective treatment."
Perhaps the only thing both sides agree on is that the technology of
ECT has steadily improved.
ECT dates from 1938 when psychiatrist Ugo Cerletti, practicing in
Italy, applied electrified tongs to the temples of a schizophrenic
patient. He and others argued that epileptics had seizures but were free
of schizophrenia, so perhaps inducing seizures in non-epileptics would
relieve the symptoms of schizophrenia.
European psychiatrists began inducing seizures by giving toxic
doses of camphor or Metrazol. Cerletti's electric technique was
convenient and seemingly safer. By 1948, about 85 percent of U.S.
hospitals surveyed said they used chemically or electrically induced
shock on mental patients. In time, psychiatrists began to see that the
electric technique worked best for people seriously depressed and on the
verge of suicide.
NO ONE REALLY knows how ECT works, only that it causes a seizure in
the brain that seems to alleviate many of the symptoms of severe
depression and mania. It is also being used experimentally to treat
schizophrenia, Alzheimer's and Parkinson's diseases.
Psychiatrists agree that modern ECT, administered with muscle
relaxants and anesthesia, has come a long way from the days when an
electric shock jarred the whole body into convulsions, often resulting
in broken bones.
Researchers at the National Institute of Mental Health estimate
that during any six-month period about 10 million people suffer
depression. An episode can last weeks or months, and the likelihood of a
future bout is high. Researchers now suspect that some forms of
depression are caused by brain chemicals gone awry.
Drug therapy is still considered the best treatment for most people
with depression. Some people can't tolerate the side effects, which can
include blurred vision, dry mouth, urinary retention, constipation,
rapid heart beat, hypotension, sedation and sexual difficulty.
Researchers say that 70 percent of patients respond to
antidepressant medications, but it may take several weeks, even months,
for people to begin to feel better. ECT, which is saved for only the
most severe cases of depression or mania, is said to work quickly, often
after the first treatment. Dr. Herbert Fox of Gracie Square Hospital in
Manhattan said that studies have shown that it is effective 80 to 90
percent of the time.
Some doctors estimate that 100,000 Americans a year receive ECT
treatments. Modern-day therapy calls for a series of six to 12
treatments, doctors say, compared to dozens, even hundreds, of shock
sessions decades ago.
But ECT is not an easy solution, nor is it a cure. It provides
temporary relief from life-threatening mental illnesses, Fox said. It is
a type of surgery, and any surgery has its limits and dangers. During
the procedure, electrodes are placed on the head and chest to record
changes in heart rate and brain waves. Electrodes are also placed on the
scalp to elicit a seizure.
Before electricity surges through the brain, patients are given an IV
barbiturate to sleep and a relaxant to calm the body's hundreds of
muscles. The bolt of electricity lasts seconds, just long enough to
produce a seizure. The anesthetic wears off in minutes, and the patient
resumes normal activity within two hours of treatment.
The majority of ECT cases are carried out in a hospital, but more
and more patients are receiving shock treatments on an out-patient
basis.
Julie, 32, of Queens, has spent most of her adult life fighting
severe bouts of depression. She has seen six doctors in as many years.
She was given antidepressants, antipsychotics, even lithium, but the
side effects were always so harsh that she was forced to stop. She was
falling so deep into her sadness that she felt that it would only be a
matter of time before she was evicted from her apartment.
"I was so emotionally dull that I was unable to connect with other
people," said Julie, who asked that her last name not be used. "I felt
so weak that I did not have the strength to look for yet another
doctor." So Julie, who was working her way through a master's degree in
social work, decided to look into electroshock therapy. Her mother also
suffered from severe depressions and found relief from shocks to her
brain.
"I read about all the side effects, and they did not sound as bad as
the ones I was experiencing on the medications," Julie said. Some of her
complaints: severe dry mouth, dulled thinking and concentration, and
anxiety. Lithium left her with disfiguring acne. She was a persistent
patient. She worked at a psychiatric hospital and did not want to take
time off to get better. She found the answer at an out-patient clinic at
Gracie Square.
There she worked with psychiatrists on a treatment schedule that
would allow her to continue work and college. She travels to the
hospital once a month for ECT treatment.
"It's a miracle. Years ago, I would have been institutionalized for
a couple of years," Julie said, pointing out that her depression has
lifted. "I am doing a lot better than most people who have never
suffered depression."
Fox and others say they worry that ECT is fast becoming a treatment
for the rich or, like Julie, at least the adequately insured. Private
hospitals are buying up ECT machines, Fox said, while state hospitals
are relying more heavily on drugs to treat their patients.
New York State, which operates 33 hospitals, is looking into whether
it should provide more ECT. According to Dr. John Oldham, the acting
chief of the state's Office of Mental Health, "We can't be sure whether
it should be used more or less. I would say that there are a few state
facilities where it is not readily available and that it can be a
problem for patients."
But making it available may also cause problems. Dr. Richard
Frances, a professor of clinical psychiatry at the University of
Medicine and Dentistry of New Jersey, said that patients' most common
complaints are confusion and memory lapses.
"These problems can be very frightening to people," Frances said.
"There is a temporary period of memory loss during the time people are
getting ECT."
While some patients complain of lifelong memory lapses, studies on
the structure of the brain have not shown any evidence of such permanent
memory loss. Dr. Matthew Rudorfer of the National Institute of Mental
Health says that he has done PET (positron emission tomography) scans on
a few patients and so far has found no brain chemical differences
between those who received ECT and those who did not. In other studies,
researchers have induced repeated seizures in rats and were unable to
detect any damage to the stimulated area. Other animal studies conducted
using MRI (magnetic resonance imaging) scans - these devices reveal
structural abnormalities - also found no changes before or after ECT.
IN ADDITION to memory problems, some patients complain of side
effects including headaches, nausea, muscle aches or soreness, weakness,
drowsiness, anorexia and missed menstrual periods, said Harold Sackeim,
an ECT researcher at Columbia University College of Physicians and
Surgeons.
More than two years after Long Island's Witte had ECT to treat her
chronic sadness, she says she is still having problems. While some of
her memories returned after her shock treatment, others from several
years before the therapy have not. After her hospital stay, she says,
she had no idea how to find her own house. She did not know the
neighborhood foodstore where she had shopped for a decade. Family
vacations were snapshots of empty weeks.
Friends, family and a long-time psychologist have helped Witte put
the pieces of her lost life back together.
"The treatment has profoundly changed her," husband William said.
"She has had to get to know me and the children all over again."
