Electroconvulsive Therapy Causes Permanent Amnesia
And Cognitive Deficits, Prominent Researcher Admits

In a stunning reversal, an article in the journal Neuropsychopharmacology
in January 2007 by prominent researcher Harold Sackeim of Columbia
University reveals that electroconvulsive therapy (ECT) causes permanent
amnesia and permanent deficits in cognitive abilities, which affect
individuals' ability to function.
"This study provides the first evidence in a large, prospective
sample that adverse cognitive effects can persist for an extended
period, and that they characterize routine treatment with ECT in
community settings," the study notes.
For the past 25 years, ECT patients were told by Sackeim, the nation's
top ECT researcher, that the controversial treatment doesn't cause
permanent amnesia and, in fact, improves memory and increases intelligence.
Psychologist Sackeim also taught a generation of ECT practitioners
that permanent amnesia from ECT is so rare that it could not be
studied. He asserted that most people who said the treatment erased
years of memory were mentally ill and thus not credible.
The National Institute of Mental Health (NIMH) estimates that more
than 3 million people have received ECT over the past generation.
"Those patients who reported permanent adverse effects on cognition
have now had their experiences validated," said Linda Andre,
head of the Committee for Truth in Psychiatry, a national organization
of ECT recipients.
Since the mid-1980s, Sackeim worked as a consultant to the ECT
device manufacturer Mecta Corp. He never revealed his financial
interest in ECT to NIMH, as required by federal law, and, until
2002, did not reveal it to New York officials as required by state
law. Neuropsychopharmacology has endured negative publicity over
its failure to disclose financial conflicts of journal authors,
resulting in the editor's resignation and a promise to disclose
such conflicts in the future; yet there is no disclosure of Sackeim's
long-term relationship with Mecta, nor did Sackeim disclose his
financial conflict when his NIMH grant was renewed to 2009 at approximately
$500,000 per year.
The six-month study followed about 250 patients in New York City
hospitals, an unusually large number; most ECT studies are based
on 20 to 30 patients. Sackeim's previously published studies were
short term, making it impossible to assess long-term effects. "However,
in other contexts over the years -- court depositions, communications
with mental health officials, and grant protocols -- Sackeim has
claimed to follow up patients for as long as five years. This raises
serious questions as to how long he has actually known of the existence
and prevalence of permanent amnesia and why it wasn't revealed until
now," Andre said.
Besides finding that ECT routinely causes substantial and permanent
amnesia, the study contradicts Sackeim's oft-published statements
that ECT increases intelligence and that patients who report permanent
adverse effects are mentally ill.
"The study is a stunning self-repudiation of a 25-year career,"
Andre said.
