Misdiagnosed for 23 Years, Rom Houben Is a Moral Lesson for Our Time
By Dave Andrusko
“The case of Terri
Schiavo--who died five years ago next March, deprived for nearly two
weeks of food and water, even the balm of ice chips--continues to
prick consciences,” writes bioethicist Wesley Smith. “That may be
one reason the case of Rom Houben, a Belgian man who was
misdiagnosed for 23 years as being in a persistent vegetative state,
is now receiving international attention.”
All those many, many
years Rom Houben, the victim of an automobile accident, had been
variously misdiagnosed as being either in a coma, comatose, or in a
“persistent vegetative state” (PVS). The common denominator was that
physicians had decided he was not conscious.
But Rom was, all
along. As Smith pointed out, “He was fully awake and aware but
unable to communicate, in a condition known as the ‘locked-in’
state.”
However, thanks to
the dogged determination of his family, Rom, a former martial arts
enthusiast and engineering student, now communicates using a
computer with the aid of speech therapists and physical therapists.
“I was only my
consciousness and nothing else,” he told his doctors. “I’ll never
forget the day they discovered me. It was my second birth.”
Like Terri, Rom would
have been a prime candidate for a hideous death by starvation and
dehydration, had it not been for his kin. His mother, Fina
Nicolaes-Houben; his late father; and his sister, Terein, never
bought into any of the diagnoses.
To jump ahead his
doctor, Steven Laureys, eventually concluded (as mentioned
previously) that Rom suffered from so-called “locked-in syndrome,”
described as “a rare neurological disorder in which nearly all the
body’s voluntary muscles are paralysed, but the patient remains
conscious and able to think and reason.”
But before this
diagnosis was made, determined not to give up on Rom, the family
“started a desperate odyssey around Belgium, France, and America on
a quest for a new chance, an inkling of better news, a hint of
medical breakthrough or discovery of some unknown expertise that
might defeat the resignation and the fatalism,” the Guardian
reported.
Many years and many
trips later—including five trips at their own expense to the Glenn
Doman Institute in Philadelphia, “a global pioneer in the treatment
and diagnosis of brain-damaged children”—Fina and Terein attended a
conference on locked-in syndrome. “The women met specialists from
Ghent and Louvain who recommended Dr Steven Laureys of Liege
University, a renowned neurologist,” the Guardian reported.
Not only was Laureys
well respected, he had become convinced that many patients
supposedly in what Europeans call a “neuro-vegetative” condition
were not. Last July, he published a paper in BMC Neurology showing
(as he told New Scientist) “that 41 per cent of vegetative patients
may actually be minimally conscious, based on the Coma Recovery
Scale–Revised.” (Minimally conscious can be described as being
profoundly cognitively impaired but showing “subtle but consistent
signs of awareness.”)
Rom is different,
Laureys said, “because he has more than minimal brain function—his
brain scans show that he has near normal function. But he has still
put a human face to the very important problem of assessing
consciousness, the importance of using a standardised scale and the
power of neuro-imaging.”
Laureys determined
Rom’s true condition, not by using fancy technology, but by
employing the Coma Recovery Scale–Revised. This “is a bedside
behavioural assessment done in a very standardised way, and which
you do repeatedly so as not to miss any signs of consciousness,”
Laureys explained. He said Rom had a lot of different scans but just
one—a PET scan—provided them with enough evidence to conclude that
Rom was conscious.
TIME magazine did an
online piece on the case (“Awaking from a Coma: What Did the Doctors
Miss?”). It’s easy to see why there is so much misdiagnosis of
brain-injured patients.
To begin with the
brains of some PVS patients do heal. Most often lodged in long-term
care facilities, patients with severe brain injuries do not have
access to specialists; the staff can easily miss the nuances.
Moreover, physicians may fail to distinguish between PVS and minimal
consciousness.
In addition,
according to TIME, “PVS and minimally conscious patients are at high
risk of infection and can be heavily medicated, which may affect
their responsiveness when tested by doctors.” Finally, “one of the
main tools for assessing brain function in intensive-care
settings—the Glasgow Coma Scale—does not perform well in chronic
cases.” Laureys “wrote that PVS patients should be tested frequently
using a standardized evaluation called the Coma Recovery
Scale–Revised, which involves more thorough tests such as measuring
patients’ eye-tracking abilities by moving a mirror slowly over
their faces.”
Laureys made it clear
that these diagnoses—which include “minimally conscious—are not
“black and white.” But that’s precisely the point. “The figures [of
misdiagnoses] are frightening but they are facts,” Laureys told TIME
magazine.
The Calgary Herald,
in ad editorial, may have put it best. “The lesson from Houben’s
case--and reinforced, sadly, too late by Schiavo’s case--is that if
doctors and courts must err, it should always be on the side of
life, and on the assumption that despite all outward appearances,
the ‘I’ is indeed there.” |
