The absence of evidence, in the absence of a valid examination of the data, or failure to put the safety issue to scientific scrutiny, is NOT an indication of safety. By that logic,
However, his question--why has no research been done on ECT's effects using MRI imaging, EEG brain waive studies, or autopsy examination of patients?-- is worth probing. Especially, in light of the contentious battle about ECT's safety between consumers who suffered the consequences, and ECT stakeholders.
The failure to conduct--or perhaps, more accurately, the failure to report--results from imaging studies and autopsy examinations, studies that would provide replicable, hard evidence of ECT effects on the Brain, demonstrates, we believe, that ECT promoters have evaded such studies for fear they would provide irrefutable documentation about ECT's brain damaging effects.

FDA panel advises
more testing of 'shock-therapy' devices
By David Brown
Friday, January 28, 2011
An expert panel advising the Food and
Drug Administration decided Friday that electroconvulsive therapy (ECT)
machines should undergo the same rigorous testing as new medical devices coming
onto the market - a decision that could drastically affect the future of
psychiatry's most controversial treatment.
The majority of the 18-member committee
said not enough is known about ECT, also known as "electroshock" or
simply "shock" therapy, to allow the devices to be used without more
research into its usefulness and hazards.
If the agency follows the panel's
advice, which it usually does, the two companies whose machines are used in the
United States will have to provide evidence of the therapy's safety and effectiveness
either from existing research or new studies. If the FDA isn't convinced, the
devices could be removed from use.
The panel's opinion is the latest
chapter in ECT's seven-decade history, during which the treatment has been
lauded as a lifesaver, villified as a form of legally sanctioned torture, and
has seen its popularity rise in recent years after a long decline.
ECT machines deliver an electrical
current to the brain, inducing a generalized seizure in which the patient
briefly loses consciousness. How that may be therapeutic or cause permanent
memory loss - the side effect most frequently mentioned by patients - isn't
known.
About 100,000 Americans undergo ECT
each year, usually getting about a dozen treatments over several weeks. Some
then get "maintenance" ECT every few weeks, as the therapeutic
effect, when it occurs, often doesn't last. The treatment is most often used
for depression and has also been prescribed to patients with schizophrenia,
catatonia, and more recently, to some violent children with autism.
"It was the best possible outcome
we could have gotten," said John Breeding, 58, a clinical psychologist
from Austin who says the procedure should be banned. He testified before the
panel at a two-day meeting in Gaithersburg.
For some patients, ECT epitomizes what
they view as the coercion and lack of respect for the patient's point of view
that is unique to psychiatry. That's also largely how it's been depicted in
popular culture, most famously in the book and film "One
Flew Over the Cuckoo's Nest," where it was a tool of punishment and
social control of mental patients.
"I lost not only my memories of
the time I was subjected to this torture but I was robbed of almost all
memories from about 2003, two years before treatment, to 2008, three years
after treatment stopped," testified Evelyn Scogin, a special-ed teacher
who got ECT after a suicide attempt. Her statement was read by a friend because
Thursday's snowstorm stranded her in the Charlotte airport.
Other patients described ECT as a
lifesaving, if mysterious, treatment worthy of wider use.
Among them was Kitty Dukakis, the
74-year-old wife of 1988 Democratic presidential nominee and former
Massachusetts governor Michael Dukakis. She first got ECT at age 63, and
continues to get it once a month.
"It is not an exaggeration to say
that I don't think I would be alive without ECT. It has been a miracle in my
life," she said.
One proponent, a nurse from Baltimore,
drove through the snow on her day off to read a grateful Christmas card from a
patient, choking up as she did.
"I actually think it's more
controversial than abortion," Amy Lutz, a 40-year-old mother of five from
Villanova, Pa., said of ECT, which her 12-year-old autistic and
manic-depressive son gets regularly.
She brought with her two poster-size
photographs of the boy, his face and hands bloodied from self-inflicted blows.
She told the committee that ECT, tried after a half-dozen other therapies,
stopped the violent behavior and increased her son's achievement in school.
A 1976 law requiring safety and
effectiveness of all new medical devices permitted ones in longstanding use, including
ECT machines, to stay on the market. Later, however, Congress told the FDA that
those grandfathered-in devices either had to undergo rigorous testing or be
officially "reclassified" as already-proven to be safe and effective
(although, in some cases with special warnings about their use).
In addition to patient testimony, the
advisory panel heard FDA staffers describe their analysis of hundreds of ECT
studies.
As a group, the studies tended to be
poorly designed and with too few patients to allow the drawing of firm
conclusions. Many failed to follow patients long enough to discover the
duration of ill effects. Ones done decades ago studied techniques and
electricity dosages different from current practice.
The FDA staff reported the existing research
suggests that for depression, ECT is more effective than placebo or
"sham" shocks and after a month more effective than antidepressants.
In terms of hazards, the FDA staff's
review found the treatment is associated with "impairment in orientation, memory
and global cognitive function immediately after ECT and up to 6 months."
Certain aspects of memory may return to baseline after six months.
"Autobiographical memory" - recollection of events in one's life -
appears to be at greatest risk. High-dose electric current and current applied
to both sides of the brain are associated with more thinking and memory
problems.
Panel member Christopher A. Ross, a
psychiatrist and neuroscientist at Johns Hopkins University, asked if the
published studies identified any risk factors that predisposed patients to
memory loss and thinking impairment.
"Evidence-based data for that
issue just doesn't exist," said Peter G. Como, a neuropsychologist at the
FDA.
Panel Chairman Thomas G. Brott, a
neurologist at the Mayo Clinic's campus in Jacksonville, Fla., said he was
amazed that essentially no research had been done on ECT's effects using
functional MRI imaging, repeated brain wave (EEG) studies, or autopsy
examinations of patients.
"I tried to look and saw very
little. I concluded that the evidence is not there to decide either way,"
he said.

THE
HUFINGTON POST
Dr. Peter Breggin
January 28, 2011 05:42 PM
Friday afternoon, January 28, 2011: The FDA's panel for electroconvulsive therapy
(ECT) voted to place ECT machines in Category III for all but one indication.
If the FDA accepts the panel's recommendation, the agency will require testing
for all uses except "catatonia" which was recommended for Category
II, requiring less stringent testing.
A tiebreaker by the chair was needed to propose putting ECT machines into
Category III for depression. Given acute trauma caused by the
treatment and the evidence for long-term memory and
cognitive problems, it reflects poorly on the panel that the vote
was so close.
The use of ECT for catatonia was recommended for Category II, apparently on
the grounds that nothing else works for that disorder. According to the Diagnostic
and Statistical Manual of Mental Disorders (DSM-IV-TR, 2000), the
qualifier "with catatonic features" can be applied to Major
Depressive Disorder or Bipolar I and II. It is also a type of schizophrenia.
If the diagnosis of catatonia is given this loophole, we will see more and
more people diagnosed with this disorder. It will be a potential medical
disaster because most catatonic-like states are now caused by drug toxicity,
including neuroleptic malignant syndrome from the antipsychotic drugs and
serotonin syndrome from the serotonergic antidepressants. I have been a medical
expert in malpractice cases in which clinicians have mistaken these toxic
syndromes for psychiatric disorders, resulting in chronic disability or death
from lack of proper treatment. I predict that thousands of patients who need
treatment for psychiatric drug toxicity will instead end up on the shock table.
On top of that, as the panel apparently recognized, there are no credible
studies of ECT for catatonic features or catatonic schizophrenia. It's a very
obscure disorder, but it will become a widespread disorder in order to justify
shock treatment. It's similar to what happened to children: massively
increasing the diagnosis of bipolar disorder to justify giving them adult mood
stabilizers and antipsychotic drugs.
It is scientifically unsound to act as though ECT causes serious safety
risks with one disorder but not another. In all cases, the same traumatic doses
of electricity are being given to the brain. The claim that there are no other
effective treatments for catatonia, whether true or false, should never be used
to justify a failure to test a device or drug for safety.
The reasonable and ethical approach for the FDA would require the agency to
call for the phasing out of ECT over a period of months while developing
protocols for testing ECT machines. It should begin with Phase I studies, like
any other dangerous treatment, and first be tested on animals. All prior
large-animal studies such as monkeys, cats and dogs have demonstrated brain
damage in the form of small widespread hemorrhages and/or cell death. My earlier blog about these hearings provides
citations to these studies. The animal studies can also be found in the bibliography on my website
and in my book Brain-Disabling Treatments in Psychiatry,
Second Edition (2008, pp. 237-241). If these studies are
reconfirmed, then ECT should be stopped without further testing on humans.
Nothing would be lost by not giving ECT during the testing period. Many
doctors never give ECT and never refer patients for ECT, and there's no
evidence that this deprives patients of a useful treatment. After all, there's
no substantial proof of efficacy and considerable proof of brain damage and
long-term cognitive problems.
Unfortunately, the FDA is already waffling about whether or not it will in
fact require the usual testing for Category III devices. In response to
questions at the hearing, the agency staff said it was not certain whether a
Category III designation for ECT would require the same rigorous testing
routinely carried out for safety and efficacy. No one on the panel seemed to
think the treatment should be phased out until safety and efficacy were proven.
Psychiatric reform moves ahead a step at a time, falters, and hopefully
moves ahead again. The classification of ECT into Category III for most
conditions, which at this point is only a recommendation, is a step forward and
a somewhat positive sign to those of us who have called for this for decades. We
hope the FDA will uphold its obligation to the public to thoroughly test such a
dangerous device for safety and efficacy.
