Confusion now hath made his masterpiece.
-- Shakespeare
Introduction
...thinking
apparatus shriveled and shrunken, withered and liquified ... eyes merely
appear to follow the actions of people and things around her ... completely
blind, taking-in nothing and recognizing nothing ... appears to be responsive,
but actually braindead; seemingly intelligent behaviors are nothing more
than reflex movements.
Is this a description of Terri Schiavo? -- No.
As we demonstrate below, this description fits not Terri but the entire mainstream
news media and the vast majority of the medical and legal experts who have
commented on the Terri Schiavo "Report of Autopsy" issued on June 15, 2005 by the Florida District Six Medical Examiner.
Whatever
the results of the Medical Examiner's (ME's) report may indicate about the
condition of Terri Schiavo at the time of her death, we know from the mainstream
media's hyped reporting that America's leading news outlets and reporters
are mindlessly ill-informed, willfully blind, thoroughly unprincipled, and
miserably unschooled in the basic principles of medicine, the scientific
method and statistics.
The news reports that the liberal media spewed-out on the Schiavo autopsy
reveal little or nothing about whether Terri was braindead, blind, and incapable
of feeling pleasure or pain. But they certainly yield insights into the sorry
intellectual, moral and politicized state of the liberal media as well as
the armies of medical and legal experts who prostitute themselves by shamelessly
dispensing legally unsound and medically unsupported misinformation and disinformation
without adequately informing themselves on the facts of the case.

What
follows is Part I of a critique of the Autopsy Report and accounts of it
in the media. This and each successive Part of the analysis presents a single
issue in Q & A form.
This Part I of the Q & A series deals with the diagnosis of Terri Schiavo
as being in a persistent vegetative state (PVS); specifically, whether or
not the ME's Autopsy Report confirmed, or lent support to, the PVS diagnosis
and provided conclusive proof that Terri was "braindead," unconscious," incapable
of feeling any pain or pleasure, and unable to think, wish, will or recognize
anyone or anything.

Inconsistent With the Truth
Before
proceeding with the analysis of the Autopsy Report on the PVS question, it
is essential to understand a certain category of medical and statistical
terminology the use of which (by the ME and the media) is responsible for
generating so much of the public's current confusion regarding the ME's autopsy
findings.
Principal among these is the term "consistent with" as utilized by the ME.
"Consistent with" is sometimes amplified by "very," as when the New York Times Editorial
of June 16, 2005 quotes the ME as explaining that the autopsy findings were
"very consistent with" a persistent vegetative state (PVS):
Although
the autopsy could not definitively establish that Ms. Schiavo was in a persistent
vegetative state, the findings were deemed "very consistent with" that diagnosis.
What the Times
and the rest of the liberal media and the medical experts "very consistently"
confused, in a manner "not consistent" with being truthful and factual, is
the fact that the term "consistent with" is as close to meaningless as you
can get in medical terms. To say that a given finding is "consistent with"
a particular diagnosis is just about the weakest connection you can make,
diagnostically speaking. "Consistent with" is about a hair's breadth short
of stating, "There was absolutely no relationship at all."
Just as a statistical correlation between two events is useless in establishing a causal connection,
so the fact that a medical finding is "consistent with" a diagnosis is virtually
meaningless in establishing what precisely the diagnosis might be.
The only really meaningful way to use the term is in excluding a diagnosis,
in those cases where you can determine that the laboratory or autopsy findings
are "not consistent with" such-and-such a diagnosis. Here the negative
is of use in establishing either: (1) the data enables a given etiology or
diagnosis to be "ruled-out" or excluded; or (2) through an arduous process
of elimination, all known "consistent with" alternatives may be excluded,
leaving only one as the presumptive explanation or cause for purposes of
making the diagnosis.
Nearly 100 per cent of the time, when physicians say that a given test result,
autopsy finding or other piece of data is consistent with a given diagnosis
or determination, that very same finding is also "consistent with" a different,
or even directly contrary, conclusion.
To say that a decedent's fractured skull is "consistent with" murder does
not lend any substantive support to the notion that the decedent was murdered,
since the same fracture may be, and often is, "consistent with" the contrary
conclusion that the decedent was not-murdered (for example, fell and hit
his head).
Applied to the Terri Schiavo case, when the ME states or implies, for example,
that his findings were "consistent with" her having been in a PVS for many
years prior to her death, every single one of those findings was equally "consistent with" the conclusion that she was not-PVS prior to her death.
When the scientific and medical data is equally consistent with both x and
non-x as in the Schiavo case, then it is utterly meaningless to suggest,
as the ME appears to have implied (predictably leaving the liberal mainstream
news media to infer) that the data supports or establishes one or the other
as true. Something meaningful has been said only when the physician or the
ME can use data to "rule-out" something, by finding that the data is "not
consistent with" such-and-such a diagnosis, or cause of death.
If the ME had said, for instance, that the autopsy findings are "not consistent
with" Terri Schiavo having been able to think, feel enjoyment and pleasure,
or feel pain, then that would have represented a meaningful finding. Adding
"very consistent with" PVS is as meaningless as saying that a woman's weight
increase is "very consistent with" her being very pregnant. A woman is either
pregnant or not pregnant, and a person is either conscious or not conscious.
Nothing in the ME's autopsy findings rules-in or rules-out the one any more
than the other. For a professional ME of many years experience to suggest
otherwise is highly misleading and scientifically reprehensible. Yet the
New York Times Editorial
of June 16, 2005 directly quotes the ME as stating that his findings were
"very consistent with" the PVS diagnosis. If true, the ME's actions would
be "very consistent with" an extreme deficiency in scientific integrity and
adherence to basic medical standards.
For purposes of understanding the Autopsy Report, the term "consistent with"
should be considered nothing more than a wild guess or a hunch -- at its
best the epistemological equivalent of a loose correlation in terms of its
level of certainty.
No responsible physician would ever perform surgery or administer medication
merely based on the fact that one or more of his findings for the patient
is "consistent with" a given disease or diagnosis. If the findings are "consistent
with" two or five or ten different diagnoses, then before embarking on a
risky course of surgical or other treatments, the ethical physician is first
obliged to rule-out all but one. In the present case, the autopsy findings
are perfectly "consistent with" two perfectly contrary diagnoses, PVS and
not-PVS, and to claim that the postmortem findings somehow lend additional
support to the PVS diagnosis in the Terri Schiavo case would be the height
of medical fraud and duplicity.
The ME's responsibility for widespread misinterpretation of the autopsy findings
in the liberal mainstream media is not diminished merely because he also
drily and perfunctorily stated deep in the text of the formal print version
of the Autopsy Report that "PVS is a clinical diagnosis arrived at through physical examination of living patients."
More serious reporters interested in accurate accounts would have been able
to discern the absence of evidence for PVS in the ME's printed Autopsy Report,
but political enterprises such as CBS News, the New York Times, the Washington Post, the Los Angeles Times, the AP
and nearly all of their politicized reporters, columnists, and editorial
staffs who handled the story ran with the "consistent with" line of fraudulent
reporting instead. Consequently, nearly the entire print and broadcast media
distributed wildly inaccurate and intentionally misleading accounts of the
postmortem findings that went uncontested, such as those below.
Q & A
Does the Autopsy Report confirm that Terri Schiavo was in a persistent vegetative state (PVS)?
MEDIA ACCOUNT:
The AP reported
on June 15, "An autopsy on Terri Schiavo backed her husband’s contention
that she was in a persistent vegetative state, finding that she had massive
and irreversible brain damage and was blind, the medical examiner’s office
said Wednesday."
Newsday went further,
claiming in its "Health & Science" section that Terri Schiavo's brain
was nothing but a mangled bundle of dead scar tissue, reporting that her
"autopsy revealed that her brain was reduced to half its normal size and
filled with scarred, dead tissue -- evidence to medical examiners and neuropathologists
that she was unable to carry out higher thinking."
The Washington Post's David Brown and William Branigin reported
that, "The autopsy essentially supported Michael Schiavo's contention that
his wife's brain damage was irreversible and that she had no cognitive ability."
Jim Axelrod reporting for the CBS Evening News:
"It's the most widely anticipated autopsy in recent memory and the results
couldn't be clearer." Proclaimed Axelrod, "That meant lost tissue, and lost
tissue meant lost functions.
The night of the Autopsy Report release, Alan Colmes on Fox News Channel's Hannity & Colmes program said,
"The Pinellas-Pasco medical examiner, Jon Thogmartin, joined by Dr. Stephen
Nelson today, described the condition as very consistent with a persistent
vegetative state."
Likewise an ecstatically deranged Keith Olbermann of MSNBC opened his program by blurting-out,
"The autopsy of Terri Schiavo is complete. She was in, and had been in, a
persistent vegetative state. She had massive and irreversible brain damage."
He manically backed-up his bold claim by asserting that the ME and other
medical authorities had put their reputations and even their medical licenses
on the line, "And if you do not believe those doctors, you have to be willing
to believe that they would be willing to lose their licenses and jobs if
they were proved to be incorrect."
NBC Today Show's Matt Lauer on June 16 may have been the one to pronounce
the final, definitive medical judgment, asserting with oracular certainty,
"The long-awaited autopsy report on Terri Schiavo was released on Wednesday.
It concluded that she was in a persistent vegetative state, suffered from
severe and irreversible brain damage."
On MSNBC's Scarborough Country, conservative Joe Scarborough thus seemed willing to throw the towel in
at last, conceding, "And this is what they came out with. They said, when
she died, Terri Schiavo, before she died, of course, had no brain activity."
What was most striking about the news reports was the smugness and certainty
with which the purported scientific "facts" of the case were misreported.
As printed in the Washington Post, famed science columnist Ellen Goodman disclosed,
"No amount of treatment or rehabilitation would have reversed her condition.
There was no doubt about it." Displaying her storied fact-checking abilities,
Goodman added, "Now we know beyond any doubt that Terri Schiavo couldn't
smile. Does this fact change even one opinion?"
MEDICAL EXPERTS' COMMENTARY:
Newsday claims to have consulted two anonymous "brain
specialists" whose conclusions seemed to completely contradict the ME's Autopsy
Report. According to Newsday reporter Jamie Talan, "The autopsy of
Terri Schiavo found extensive damage throughout her brain, according to two
Florida brain specialists who read the report. She lost all or most of her
ability to think, recognize people and objects, and perform the simplest
actions." Talan claims these two unsourced experts (she does not inform us
whether they are neurologists, psychologists, or correspondence school grads)
reported to her on the state of Schiavo's cerebral cortex. According to these
"experts" there was, "Sever [sic] damage, with little gray matter left in
the area responsible for thinking, remembering, math and higher thought.
This suggests a persistent vegatative [sic] state." We only hope that
their medical knowledge and Jamie's reporting skills exceed her ability to
spell and her Newsday editors' ability to edit and verify unnamed sources.
Interviewed on the CBS Evening News
with Bob Schieffer (see article with video link), just after release of the
ME's Autopsy Report, Dr. Douglas Miller, Director of Neuropathology at New
York University Medical Center, had this exchange with CBS's Jim Axelrod
concerning the Schiavo autopsy findings:
Dr.
MILLER: This person could not perceive things from the outside at a conscious
level, neither pain nor thirst nor who was around her.
Unidentified Man: (From videotape, speaking to Terri Schiavo) Open your eyes up! Good, good job!
AXELROD:
So that familiar piece of videotape Schiavo's family and friends pointed
to as evidence she was aware, has another definitive explanation according
to...
Dr.
MILLER: She was not aware, and appearances to the contrary in the videotape
that was shown over and over and some of the accounts, those were reflexes.
We know
how Senate Majority Leader Bill Frist was excoriated in the media for merely
suggesting that, while she was alive, Terri Schiavo may not have merited
the PVS diagnosis based on his observation of videotaped recordings of her
apparent conscious responsiveness.
Yet Schieffer and Axelrod are wildly ecstatic upon hearing Miller's method
of error-proof PVS diagnosis-at-a-distance based on nothing more than postmortem
findings in an Autopsy Report. The CBS duo never inquire of Miller whether
he viewed the entire videotape (rather than just clips of a few seconds length
shown on the network news shows). They are undoubtedly aware that he was
rendering an expert opinion and expressing absolute certainty on the PVS
diagnosis, without having never examined the living patient and while relying
exclusively on a thoroughly misleading and self-contradictory ME remark on
the Autopsy Report. Yet the NYU medical expert continues to express absolute
certainty on the PVS diagnosis to a ravenous Axelrod, denying with the certainty
of a medieval authority even the slightest possibility that others, from
family members to expert neurologists, consistently observed conscious responses
in Terri Schiavo:
AXELROD: Not possible, at least medically speaking, says Miller. In fact, she was blind.
Dr.
MILLER: [Those who claim Terri was conscious and responding to her environment]
were seeing what they wanted to see, which is common and unfortunate.
In a
June 16, 2005 broadcast segment, CBS's Axelrod, sensing the problem in concluding
from postmortem autopsy findings to Terri's clinical function while alive,
presses the NYU neuropathologist Dr. Miller on the postmortem brain weight
finding's significance for the PVS diagnosis:
AXELROD: That meant lost tissue, and lost tissue
meant lost functions.
Dr.
DOUGLAS MILLER: Wouldn't recognize anybody's face, wouldn't recognize anybody's
voice, wouldn't respond to stimuli in anything but a reflexive way.
AXELROD: This autopsy is conclusive about that?
Dr. MILLER: In my opinion, yes.
This sort of desperate effort by Schieffer, Axelrod, et al
to accumulate and promote fraudulent data that confirms a preconceived notion
based on purely political motivation is reminiscent of a similar effort by another recent divinity at CBS, Dan Rather. While CBS News
anchor, Dan Rather became the point man for a scandalous journalistic effort
that ultimately cost him his job and his reputation, the attempt to defeat
the Republican incumbent in his presidential bid based on fraudulent memos
from an obviously unreliable source. CBS appears to have figured-out that
phony journalistic accounts and pseudo-expert opinions on the Autopsy Reports
of already euthanized women provide a safer route to political success for
the "news" organization.
We would like to know which one is the medical fraud: Dr. Frist, who spent
an hour or more viewing the court-sanctioned videotaped examination of Terri
Schiavo and merely raised a question about the PVS diagnosis; or Dr. Miller
of NYU, who probably never viewed the extended tape of the live patient and
who made a definitive PVS diagnosis based on the postmortem findings of the
ME who himself wrote in the Autopsy Report that no conclusion as to PVS is
legitimate based on the postmortem findings? We think it is obvious
which of the two is more deserving of the prize for Outstanding Fraud of
the Year. The only problem is that the right to the prize is being claimed
by so many other medical experts, and by Bob and Jim and the rest of the
integrity-challenged mainstream media.
LEGAL OPINION:
The principal blog on legal aspects of the Schiavo case, Abstract Appeal,
states that: "The medical examiner's report explains that whether someone
is in a persistent vegetative state is a clinical diagnosis that his office
cannot evaluate after her death. However, the report does offer findings
that are relevant to the PVS diagnosis."
On MSNBC's The Abrams Report, a less scrupulous but thoroughly mindless Dan Abrams felt sufficiently vindicated to dictate
to his viewers, "Terri Schiavo's autopsy is complete. It sure seems her husband
was right, that Terri was in a persistent vegetative state."
MEDICAL EXAMINER FINDINGS:
In the official print version of the Autopsy Report
the ME, Dr. Jon Thogmartin, asks and answers: "Was Mrs. Schiavo in a persistent
vegetative state (PVS)? - This can't be determined posthumously, though the
findings of the autopsy were not inconsistent with this diagnosis: PVS is
a clinical diagnosis arrived at through physical examination of living patients."
In spite of this caution lying unconscious in the print version of the ME's
own Autopsy Report, Stephen Nelson, MD (consultant neuropathologist to the
Medical Examiner and author of a major section of the Autopsy Report) reportedly
did not hesitate to comment
at the news conference in which the Autopsy Report was released: "There's
nothing in her autopsy report, in her autopsy, that is inconsistent with
persistent vegetative state."
At this June 15th news conference, Nelson also remarked that the Autopsy
Report's findings are "very consistent with persistent vegetative state."
According to Keith Olbermann,
Dr. Nelson also concluded that Terri Schiavo "would not have been able to
form any cognitive thought -- meaning no thinking, no emotion, no recognition
of people. She couldn't have swallowed, and she was blind."
It is astonishing that both of the Medical Examiners principally responsible
for the Autopsy Report acknowledge in the print version that it is illegitimate
to use postmortem findings to retroactively make the clinical diagnosis of
PVS, and yet in speaking to the press they make a point of repeatedly and
consistently violating their own prohibition. In spite of the fact that the
written report appears to have been cleansed of the more extreme forms of
scientific dishonesty evident at the news conference, subtler manifestations
are nonetheless apparent in the written report as well.
Our Reply to the Medical Examiner's Spin of the Autopsy Report's Objective Findings
As Thogmartin and Nelson clearly state in the written Autopsy Report, it
is impossible to confirm a diagnosis of PVS postmortem -- on the basis of
their own autopsy. As explained above, to say that the autopsy is "consistent
with" persistent vegetative state is utterly devoid of meaning because it
is just as true that the autopsy is "consistent with" Terri's having been
in a conscious state of one level or another.
Therefore it was extremely misleading, and even medically reprehensible,
for either ME to have stated to the press that the autopsy results are either
"consistent with" or "not inconsistent with" a PVS diagnosis, without in
every instance where the topic of PVS arose, emphasizing and repeatedly cautioning
the press in the strongest possible terms that such a statement must not
be misinterpreted as lending support to the PVS diagnosis. This caution appears
not to have been given at the news conference.
The use of "consistent with," "very consistent with" and "not inconsistent
with" decoupled from a blaring warning against misinterpretation provided
the unscrupulous and politically-motivated members of the liberal mainstream
media an opening to produce thoroughly dishonest reports and editorial commentary.
Blindly led by the political machines of the New York Times and the Washington Post,
as well as CBS and MSNBC, many news outlets dispensed intentionally falsified
news and commentary leaving the clear impression with the public that somehow
the Autopsy Report either directly confirmed the PVS diagnosis, or excluded
the possibility that Terri Schiavo was minimally -- or more than minimally
-- conscious.
Having flooded the airwaves and filled the newspapers with this sort of junk
medicine and junk reporting, aided and abetted by the ME and other willing
accomplices among medical experts lacking any scruples, the liberal mainstream
media prepared the ground for the next stage of the Crusade for Death, a
series of fraudulent polls
such as those conducted prior to Terri Schiavo's being euthanized. Legitimate
polling data on the significance of the Schiavo case will, as before, go
unnoticed in favor of the usual phony push-poll technique of manipulating public opinion.
We contend that this is more than a minor sin of omission on the ME's part;
it is tantamount to a supersized-Big Lie. Without pretending to know what
was in the minds of Drs. Nelson and Thogmartin, we might with justification
raise the question whether this was a knowing and intentional deception on
their part, particularly since the text of the Autopsy Report itself carefully
had been scoured to rid it of any such misleading verbiage.
It bears repeating that Nelson's irresponsible statements to the press are
all the more egregious in light of his own concluding statement in the written
Autopsy Report, in which he pronounced clearly that "Neuropathologic examination
alone of the decedent’s brain -- or any brain, for that matter -- cannot
prove or disprove a diagnosis of persistent vegetative state or minimally
conscious state."
We are convinced that Nelson either knew, or should have known, that his
irresponsible and misleading "consistent with" and "not inconsistent with"
statements to the press would predictably lead them to conclude that the
autopsy directly supported the diagnosis of PVS. Dr. Thogmartin sat there
and did nothing to contradict, or even qualify, what his colleague Dr. Nelson
had to say.
The press and the public cannot be expected to know that beginning with the
pioneering work of the great nineteenth century neurologist and neurophysiologist
Duchenne
it has been clear that clinical diagnoses and assessments of the quality
and extent of the mental and motor functioning of the brain and the nerves,
and the muscles they control, can only be obtained in the living patient,
not postmortem. This applies not only to the higher mental functions but
also to complex movements and expressions, from smiling and eating, to tracking
visual objects. We know far too little about the functioning of the brain
and particularly about its plasticity to be confident in drawing such inferences
from autopsy findings.
Original Observations on the Autopsy Report: With Specific Reference to the PVS Diagnosis
Medical Examiner & The Media: Bulimia of the Brain.
The principal finding by the ME that was interpreted by the media and medical
experts as supporting the PVS diagnosis was Terri Schiavo's brain weight.
The ME's Autopsy Report disclosed that at the time of death Terri's brain
weighed 615 grams, barely half the normal brain weight. The ME refers to
sex, age, weight, and height differences without providing any data on the
breakdown for these categories, and there is no supporting data on the standard
deviations or correlations with level of brain function in severely brain-damaged
patients. The impression is left with the press and the public that there
is hardly anything left of Terri's brain that works, and that the autopsy
findings conclusively prove that all of the important centers of cognitive
and other high-level human functioning including volition, emotion, sense
perception and feeling pain were utterly disabled if not destroyed.
Yet as we indicate below, the regions that govern cognition and emotion were
largely intact in Terri's brain, and we have uncovered new findings in the
medical literature suggesting that at least a large portion of the reduction
in the weight of Terri's brain is likely attributable to the dehydration
process to which she was subjected in being euthanized.
As we illustrate below, the media mimicked the ME in consistently mischaracterizing
the degree of Terri's brain damage and the purported significance of her
brain weight postmortem. The use of brain weight to support the PVS diagnosis
may turn out to be as much of a fiction as the scandalous misattribution
of her weight loss prior to 1990 to an imaginary diagnosis of bulimia for
purposes of her husband's lawsuit. While the ME was at pains to refute the
evidence for the fraudulent bulimia claim in the Autopsy Report, he merely
substituted for it an equally absurd claim that Terri was in a PVS based
on a spurious diagnostic entity invented for the ME's purpose -- what might
be termed "shrunken brain syndrome."
Shrunken, Shriveled, Withered, Liquified.
The media had a field day kicking around Terri's brain. It was common for
the press to characterize her brain as if she were a victim of a head-shrinking
tribe in deepest, darkest Africa. Before the autopsy, Terri's brain was frequently
described as "liquified" by certain of the more refined members of the press
corps, as if it had been removed, whipped-up in a blender, and then poured-back
into her skull.
"Reporting" for NPR'S All things Considered on March 24, 2005, the celebrated liberal brain scientist and plagiarist
Nina Totenberg remarked that "Terri Schiavo has been in a persistent vegetative
state, that her cerebral cortex has been liquified, that she cannot feel,
sense or think, and that she has no chance of recovery." And the entrancing
Nina knows what that's like, no doubt from personal experience.
The release of the Autopsy Report on June 15, 2005 has unleashed an orgy
of celebration in the media and Democratic Party circles over the diminutive
size of Terri's brain postmortem, many of the characterizations being extraordinarily
vicious and mean-spirited.
MSNBC presented an uplifting AP report
about plans for releasing photographs of Terri's brain, citing "George Felos,
Michael Schiavo's attorney, as revealing that Michael Schiavo plans to release
autopsy photographs of her shrunken brain in the near future."
The Washington Post painted
a delightful portrait of its own, enlightening its readers with the insight
that, "A meticulous study of the organs, fluids, bones, cells and medical
records of the Florida woman who became a cause celebre over the ‘right to
die’ also found that her brain was severely shriveled and weighed about half
that of a normal adult's."
Not to be outdone, the New York Times offered
its own enchanting image, "An exhaustive autopsy found that Terri Schiavo's
brain had withered to half the normal size since her collapse in 1990 and
that no treatment could have remotely improved her condition, medical examiners
said on Wednesday."
The earlier false account of "liquification" of Terri's brain notwithstanding (hydrocephalus ex vacuo
due to brain atrophy is the actual process in which the space previously
occupied by the atrophied tissue is replaced by cerebrospinal fluid), the
finding of decrease in the size of Terri's brain should come as no surprise
given the fact that she was deprived of all liquids and food for the two
week period immediately prior to her death.
The brain no less than the rest of the body is composed largely of water.
Common sense dictates that there will be significant weight loss in all organs
under circumstances of extreme longterm dehydration.
Recent research confirms what common sense suggests, demonstrating that even
shortterm dehydration lasting merely hours can produce substantial decrease
in brain volume and, we might expect by extension, brain weight. At this
point it is impossible to determine to what degree Terri's presumed loss
in brain weight is attributable to longterm cerebral atrophy vs. nearly two
weeks of total dehydration. Even a basic standard of decency, integrity and
respect for truth would surely suggest, however, that the ME should have
exercised more caution rather than heedlessly contributing to the utterly
predictable "shrunken brain," "shriveled brain," "withered brain" stories
that completely dominated the reporting.
In an article published just this year in the leading journal, Neurology,
Dr. Duning and colleagues report that even shortterm dehydration lasting
16 hours can produce a significant decrease in brain volume in excess of
a half of a per cent. Not directly answered in this study is the question
whether the rate of decrease in brain volume due to dehydration directly
corresponds to the overall bodily loss of weight, though this is certainly
likely. In any case, common sense suggests that much of the loss of weight
in Terri's case might be explained as a consequence of longterm dehydration
over the two week period after her feeding tube was disconnected and she
was denied any hydration or sustenance of any kind. The ME omitted all data
on overall weight loss as a result of dehydration from the Autopsy Report
on Terri Schiavo, though the report does indicate Terri's weight at the time
of death was 112 pounds, providing a basis for comparison if she was weighed
prior to removing her feeding tube.
Recovery of Mental Function: Evidence from Hemispherectomy.
Every week it seems there is a story in the media about the amazing brain
with its ability to recoup from injuries due to its marvelous functional
plasticity. This extraordinary capacity of the brain permits an injured brain
region that controls for instance language or music or intellectual ability
or motor function to effectively "relocate" itself to alternate uninjured
areas and rebuild from scratch seemingly lost capacities and connections.
In recent years and months any number of television programs
have been aired and a veritable barrage of articles written concerning individuals
with intractable seizure and other neurologic disorders who have undergone
a procedure known as hemispherectomy, in which all or most of the diseased side of the brain is removed surgically.
Clearly, hemispherectomy patients suffer an extreme loss in brain weight
(approaching the 50% loss supposedly suffered by Terri) even though in cases
where the alternate method of functional hemispherectomy is used, something
less than the full half of the brain is removed. These operations are usually
highly successful, especially in children, most of whom regain normal intellectual,
language and other functioning.
This is not at all to suggest that a PVS diagnosis is always unwarranted
in patients who suffer an extreme degree of brain atrophy resulting in a
loss of a large percentage of the brain's volume or weight. Yet it is just
as impossible to conclude from a postmortem finding of low brain weight that
the patient was PVS prior to his death.
With respect to the question of PVS, Terri's autopsy is perfectly incapable
of providing instructive answers. While a marked loss of brain weight or
volume after surgery or other brain insult is "consistent with" PVS, it is
equally "consistent with" a minimally conscious state or even a fully conscious
state. The level and state of consciousness is a function of a variety of
factors most of which are not meaningfully illuminated by an autopsy -- or
brain weight. Most hemispherectomy patients return to a fully conscious state,
with restoration of cognitive and other abilities, despite suffering loss
of half, or nearly half, of their brain weight. At least as important as
the brain's weight is the determination of which areas of the brain are lost
to surgery, trauma or other forms of insult.
Error Rate in PVS Diagnosis.
As noted
many times during the course of the controversy over whether to euthanize
Terri, the diagnosis of PVS is subject to an error rate as high as 43 per
cent even when the evaluation is done in living patients, according to a
study by leading investigators and carried out at the Royal Hospital for
Neurodisability, London and published in the British Medical Journal. Should life and death decisions be made on the basis of a diagnostic category misapplied in nearly one out of every two cases?
Postmortem assessments of PVS are completely illegitimate and anyone such
as Dr. Miller of NYU who treats postmortem data as sufficient to establish
a conclusive diagnosis of PVS is practicing junk medicine. What basis does
Dr. Miller have to appear on CBS Nightly News to ridicule family,
friends, and physicians who carefully studied Terri Schiavo when she was
alive and reached the contrary conclusion? Did Dr. Miller ever examine her
during her life? Did he ever read her entire patient record? Did he view
the full videotapes of her being examined by neurologists who are disability
experts? Did he read their reports or listen to their comments?
Some of the more irresponsible diagnosticians with purported "expertise"
in assessing consciousness may even have a demonstrable track record of 100
per cent misdiagnosis rate in PVS. This will be demonstrated in a future
publication in which we will discuss the diagnosis of PVS in Terri's case.
We maintain that for all of the above reasons it was misleading for the ME
to employ the language of "consistent with" to suggest to the press and the
public that the weight of Terri's brain was of substantive evidentiary value
on the PVS question.
We also contend that Dr. Nelson's comparison in the Autopsy Report of the weight of Terri's brain to that of another patient, Karen Ann Quinlan,
is equally misleading and liable to being criticized as intentionally deceptive.
To the best of our knowledge, Karen Ann Quinlan died naturally
of pneumonia and was not euthanized by means of longterm dehydration. It
would therefore seem that for this reason alone there is little if any basis
for comparison. The reference to Karen Ann Quinlan in the Autopsy Report
appears to be gratuitous; yet another possible example of intentional misrepresentation
and deception meriting inquiry as to its significance and motivation.
Irreversibility of Brain Damage: non sequitur.
We were extremely disappointed in the intellectually dishonest comments of
Medical Examiner Dr. Jon Thogmartin on the issue of Terri's putatively irreversible
brain damage. The ME stated that, "This damage was irreversible, and no amount
of therapy or treatment would have regenerated the massive loss of neurons."
This account is a prime example of a non sequitur, falsely suggesting that the antecedent somehow supports the consequent.
Now, by definition, since neurons cannot be regenerated in the living human
brain, when neurons die there is no way they can be regenerated. This is
true of every person alive, not just Terri Schiavo, since in varying degrees
we have all suffered a limited quantity of non-regenerable neuronal death.
For most of us the loss of a certain number of neurons over the course of
our lives is not noticeable until we reach an advanced age. To state that
Terri's neuronal loss, as being irreversible, is somehow special, or particularly
significant, is therefore completely misleading. All neuronal loss is "irreversible,"
as Dr. Thogmartin well knows.
Patients who undergo major brain surgery and victims of serious head injuries
and other brain insults and disease processes have all suffered significant
death of neurons, none of which can be regenerated. In consequence, to this
extent they have all suffered "irreversible brain damage." But the vast majority
can recover significantly from their temporary loss of motor or mental function,
without meriting anything like a PVS diagnosis.
Once again, the ME is being at best unintentionally misleading and at worst
intentionally deceptive by making the utterly meaningless and even tautological
statement that, "This damage was irreversible, and no amount of therapy or
treatment would have regenerated the massive loss of neurons." In doing so
he leaves the clear impression with the press and the public that there is
something special, final and irreversible about the effect on mental functioning
of the death of neurons in Terri's particular case.
Out of the "fact" that Terri has allegedly sustained some unique type or
extent of neuronal loss "consistent with" PVS, the ME creates the utterly
false impression that this proves beyond doubt that in fact Terri was braindead
and that in all of the areas of mental and motor functioning she would never
have received any benefit from therapy while she was alive.
These two points are completely distinct and the distinction needs to be
maintained by any legitimate ME issuing an Autopsy Report, if he is to avoid
the accusation of extreme negligence and irresponsibility, or worse: (1)
autopsy data on the distribution and quantity of neuronal damage in the brain,
all of which entails permanent and irreversible loss of neurons; and (2)
whether the patient can recover function through medication, surgery, rehabilitation,
or the natural healing process.
Dr. Thogmartin appears to have utterly confused the two concepts in a manner
that can only be described as reprehensible for being extremely negligent
and misleading in an official charged with the objective, factual, and accurate
assessment of the cause of death in Terri Schiavo's case. If this is true,
he deserves the sharpest possible criticism, even if he claims that his extremely
misleading statements were not designed to deceive. It is difficult to imagine,
however, that he did not anticipate how these reckless remarks would have
been received, interpreted and deployed by the rabidly pro-death mainstream
media.
It must be said that, in the Thogmartin-Nelson Autopsy Report and news conference,
no less than in the media reports, the facts of Terri's case have been consistently
stated in a slanted and tendentious way to suggest that the postmortem evidence
is confirmatory of PVS and irreversible loss of all conscious function, something
that can hardly ever be established by postmortem data. This includes the
opportunity for Terri to regain the ability to eat and drink by mouth, as
we will explain in a subsequent section of this Q & A series.
Perhaps the most deplorable medical commentary on the Schiavo case in general,
and the Autopsy Report in particular, has come from the renowned forensic
pathologist Dr. Michael Baden. On Fox's show, On The Record With Greta Van Susteren,
Baden mystically intuited from the 2005 autopsy findings, "The damage occurred
in a few minutes in 1990, [her brain] shrunk down to less than half its size
and all of the cells for consciousness, all of the cells for seeing, she
was blind all this time, all the cells that could recover and give her more
function just disappeared."
PVS vs. Preservation of the Frontal and Temporal Lobes.
What went largely unreported in the media is the interesting section of the
Autopsy Report entitled, "Neuropathology Macroscopic Description," written
by Dr. Nelson, wherein he coldly observes without comment that, "The changes
seen were striking in their appearance, and global in their distribution.
They predominantly involved the border zone ("watershed") areas and were
most severe in the occipital lobes, with relative preservation of the frontal
and temporal lobes." The ME also remarks, "The frontal temporal and temporal
poles and insular-cortex demonstrated relative preservation."
While Nelson here does nothing to quantify "relative preservation," it is
worth noting that the "relative preservation" of the frontal and temporal
lobes speaks, if anything, against the diagnosis of a PVS state and is certainly
"consistent with" higher cortical functioning with consciousness of some
degree. This finding is of no evidentiary value on the PVS question apart
from the fact that it makes it all the more illegitimate for any medical
expert or the media to conclude from the Autopsy Report to a PVS diagnosis.
As meaningless as this term "relative preservation" may be, the preservation
of these brain regions makes the autopsy "consistent with" consciousness.
This includes anything ranging from a minimally conscious state, to some
variant of the "locked-in syndrome"
in which the paralyzed patient is conscious, but unable to move or form meaningful
sounds -- essentially a prisoner trapped in his own body. Clearly this fact
alone does not dictate that Terri had to have been cognitively "normal" or
even conscious at all. Nor does it prove, as one medical ethicist has suggested through WorldNetDaily,
that "What this tells us is that her cortex retained function." As noted
above, such determinations are entirely outside the scope of postmortem data
and can be made only through examination of the living patient.
New Explanation for Terri's Putative Cortical Blindness: Dehydration
There is yet another potentially spurious interpretation of the objective
data by the ME in the Autopsy Report: his suggestion that Terri suffered
from total cortical blindness predating her death. Cortical blindness involves
severe neuronal loss in the brain's visual cortex despite eyes that are anatomically
and structurally healthy and intact.
The clear implication is that court-ordered videotapes of neurologic examinations
from 2002 in which Terri Schiavo clearly appears to track visual objects,
and visually recognize and react to people in her environment are examples
of merely coincidental reflex movements being misinterpreted as visual and
other conscious mental responses due to wishful thinking on the part of those
wanting to keep her alive.
"Her vision centers of her brain were dead," the ME claimed. Thogmartin continued, "Therefore, Mrs. Schiavo had what's called cortical blindness. She was blind, could not see."
The clear implications of the ME's assertion (not to mention its mocking,
hymnal tone) are: (1) that Terri was totally blind for the weeks, months
and years prior to her death; and (2) that the widespread impression that
she had vision and the capacity to track objects and even recognize people
is a complete fiction or delusion on the part of her supporters, including
neurologists who are experts in disability assessment. The statement, "She
was blind, could not see," is senseless if limited to the period after her
death or even the two week period where she was dying of dehydration. The
ME's claim makes sense and has significance only if he was referring to the
years and months prior to her death when she was being sustained by a feeding
tube and her supporters were fighting to keep her alive.
Whatever his thought process, it is certain that the ME's contention that
Terri suffered from cortical blindness predictably left the absolutely clear
and unmistakable impression with the press and the public nationwide and
worldwide that for years and years prior to her death Terri was totally blind
and never saw or recognized anybody. Here the ME was contradicting the claims
of parents, siblings, and friends who interacted with her, and several of
the physicians and neurologists specializing in disability assessment who
very thoroughly examined her level of mental, sensory and motor functioning
back in 2002.
Leaving aside the claims of her supporters that Terri was sighted, prior
to removal of her feeding tube and particularly back in 2002 when she was
videotaped seemingly responding to visual stimuli, there are several factors
that call into question both the ME's diagnostic interpretation and his personal
motivation in communicating it:
(1) It is necessary to point out that it is virtually impossible for an autopsy
to firmly date the onset of cortical blindness in a case such as Terri's.
The mere fact that a decedent has massive neuronal damage to the occipital
lobes at the time of autopsy does not prove that all or any such damage was
present one month, one year, or one decade prior to death. On these grounds
alone, we can say that Dr. Thogmartin was unwarranted in interpreting the
findings as he did. Thogmartin all but dictated to the press that, back in
2002 when the court-sanctioned videotapes were made of her clearly appearing
to track visual objects, this was all an illusion, and: "She was blind, could
not see." We may cite on this question no lesser authorities than the two
MEs, Drs. Thogmartin and Nelson themselves, as acknowledging in their written
Autopsy Report that it is not legitimate or reliable to retroactively diagnose
the clinical state in a living patient using that patient's postmortem findings
-- particularly when the higher mental, sensory and motor functions are in
question.
(2) There is nothing in the autopsy findings that negates the possibility that, having sustained a severe anoxic insult to her brain in 1990 (or at some later stage) causing major damage to her occipital lobes, Terri suffered for years not from total cortical blindness but from some degree of what is known as cortical visual impairment.
To use the language of the ME, it is perfectly "consistent with" the postmortem
findings that the damage to her occipital lobes occasioned a less-than-complete
blindness. There are several possible causes of occipital lobe damage capable
of causing cortical blindness or cortical visual impairment, one of which
is elevated pressure
due to hydrocephalus. -- To repeat, the postmortem finding reported by the
ME, of "hypoxic damage and neuronal loss in her occipital lobes which indicates
cortical blindness," is by no means proof that Terri was totally blind either
in 2002 or even early in 2005 prior to implementation of the dehydration
order. While this postmortem finding is "consistent with" longterm total
cortical blindness, by no stretch of the imagination does it provide proof
that she was totally blind during the years, months or even weeks prior to
her being euthanized by dehydration. The fact is, there is every reason to
suspect that Terri Schiavo had partial vision for years prior to the execution
of the dehydration order.
(3) Lastly, we suggest it is also possible, according to recent reports in the medical literature such as this,
that the devastating dehydration to which Terri was subjected during the
last two weeks of her life, might have exacerbated her already existing cortical
visual impairment. This dehydration, producing varied neurotoxic effects
not at all limited to the loss of basic brain weight and volume referenced
above, may have induced an ischemic insult in the occipital cortical region
thereby occasioning significant neuronal loss that was magnified as the effects
of dehydration progressed. It is not our intent to explain the actual mechanism
that might have led to the objective autopsy finding of pervasive damage
to the occipital lobes, but merely to remind the ME, the press and the public
that such a postmortem finding does nothing to prove the existence of total
cortical blindness prior to the inception of the dehydration process. --
What might have been the effects of dehydration on Terri’s visual cortex,
and did the dehydration process hasten the demise of already vulnerable brain
structure? -- Based on the autopsy, there is reason to believe that back
in 1990, Terri's visual cortex had borne the brunt of the anoxic attack in
which she sustained profound damage to the occipital lobes and proximate
regions of her brain. We may speculate that the already impaired visual centers
of her brain were therefore most vulnerable to subsequent insults such as
the severe dehydration that caused her death when her feeding tube was disconnected.
Accordingly, what the ME found at autopsy may reflect the accelerated effects
of extreme dehydration within the last two weeks of her life upon the already
diseased visual cortex rather than what would have been the state of Terri's
visual cortex had she not been deprived of fluids and feeding through her
feeding tube.
All of the above evidence suggests that the Medical Examiners, Drs. Thogmartin
and Nelson, likely went into the autopsy process with the preconceived notion
that Terri Schiavo was in a persistent vegetative state (PVS), incapable
of any human mental functioning or even feeling pain, despite convincing
evidence to the contrary. By bending and breaking the rules and standards
of science and medicine, including those contained in their own Autopsy Report,
they convinced themselves of the veracity of what they already knew prior
to autopsy, and identified data such as reduced brain weight and cortical
blindness that supported their preconceived conclusions. They then set about
systematically providing the press with their manufactured "evidence" for
the PVS diagnosis, knowing that the impatient liberal mainstream media was
primed to spread these lies to the public in order to advance their political
and social agenda.
Concluding Postscript to an Unscientific Autopsy Report: A Medical "Wilding"
The ME's Autopsy Report, and the reporting on it, provide an object lesson
in media and medical misinformation and deliberate distortion, amounting
to a "medical wilding" with Terri as its victim.
On virtually every issue of importance to her family and public policy, the
ME's Autopsy Report lent itself to misinterpretation and misuse. If our analysis
is correct, the statements to the press by the ME were tendentious, negligent,
and irresponsible in the extreme, and their PVS inferences from the limited
facts and objective findings of the autopsy were consistently unsupported
and designed to deceive. The contrast between their reckless remarks at the
news conference, and the somewhat more carefully stated facts presented in
the print version of the Autopsy Report, further support the suspicion that
they were pursuing an agenda in their presentation but wanted to hide behind
more cautious formulations in the formal report.
Their distorted interpretations of the facts both in the print version and
particularly in the news conference directly contributed to wildly misleading
reports in the liberal mainstream media and the other pro-death propaganda
mills.
In our opinion, the Pinellas County Medical Examiner Dr. Jon Thogmartin and
the consulting forensic neuropathologist Dr. Stephen Nelson, the Medical
Examiner of Polk County, who jointly produced the Autopsy Report, deserve
criticism no matter what their explanation. Either they intentionally deceived
the public with comments that lent themselves to predictable misuse by the
politically motivated liberal mainstream media, or they were incompetent
and negligent in not anticipating the consequences of their confused, misleading
and equivocal statements.
Their unscientific interpretation of the facts and their biased presentation
was irresponsible in the extreme. Cautionary statements buried deep within
the text of the Autopsy Report do not provide adequate cover for a presentation
that in the overall sense followed an arc of untruth and provided ammunition
to those in the media engaged in an aggressive assault on the truth for political
purposes. In most cases this was due to Thogmartin and Nelson ignoring their
own cautions against drawing unscientific inferences about the functional
capacity of Terri Schiavo's mind and body during her lifetime, based on the
physical state of her brain at the time of autopsy.
The strategy of the liberal mainstream media and the biased medical experts
on whom they relied for cover in analyzing and interpreting the facts, is
the scientific equivalent of the proverbial cheating husband caught in the
act by his wife. The husband, caught in flagrante dilicto, says, Look, honey, what are ya gonna believe, what I tell you or your own lying eyes?
The media promulgated the deception that everyone’s eyes really did lie,
that the videotapes clearly showing Terri recognizing her relatives and expressing
pleasure and pain were the product of delusions and hallucinations. Armed
with the ME's misleading interpretation of the postmortem data, the media
was convinced it had a license to purvey the Big Lie that Terri Schiavo was
merely a mindless lump of withered matter, a mere vegetable, incapable of
thought, will or emotion and even incapable of feeling pain -- functioning
merely by the same reflex jerking seen in a recently severed frog’s leg.
Some frog, some leg.
It is the liberal mainstream news media that is braindead and beyond resuscitation.
They are the ones who have suffered total blindness, who are permanently
and totally incapable of seeing or recording or reporting reality. Their
minds and souls and senses are completely withered, neuronally dead, irremediably
and irreversibly so. They are sustained by their corporate feeding tubes
and financial life support, dying a very slow, slow death without feeling
any twinge of pain or remorse. Yet in their case no judicial authority exists
to order mercifully that the plug be pulled.
The autopsy report is yet to be written.
