The
last time I saw Margaret Worthen was in November 2012. She was in New
York participating in a study of patients with severe brain injury. As
soon as I walked into her room, I knew something had changed. She was
still immobile, but she noticed my presence, was more attentive and
engaged. And there was something else: She at times was able to use her
left eye to answer simple yes or no questions. That morning, she seemed
to relish her new found fluency. She responded with verve, as if the
determined downward swoop of her eye could signal an exclamation point.
Communicating
with one eye may not seem like much, but it was something to behold.
Maggie, as she was known, had suffered a complex stroke six years
earlier, during her senior year at Smith College, that involved areas
deep in her brain. She had been thought to be in the “vegetative state” —
the term commonly used to define the unconscious brain state most of us
associate with the right to die movement and the legacies of Karen Ann
Quinlan, Nancy Cruzan and Terri Schiavo.
Later,
Maggie was found to be in the “minimally conscious state” — a term
medically formalized in 2002. Unlike vegetative patients, those in MCS are
conscious. They demonstrate intention, attention and memory. They may
reach for a cup, say their name and notice you when you walk into their
room. The problem is that these actions may be rare and intermittent, so
when family members who witnessed them share their observations with
staff members, they are often attributed to a family’s wishful thinking.
This may be true in individual cases. But often it is just part and parcel of the biology of MCS.
Indeed, at least one study
indicated an alarming rate of misdiagnosis: it found that 41 percent of
patients with traumatic brain injury who were in chronic care and
thought to be in the vegetative state were in fact in MCS.
If
not for the astute observations of her Boston neurologist, Maggie, too,
would have been misdiagnosed in perpetuity. But instead, she was
expressing herself one blink at a time. For a young woman who had been
thought permanently unconscious, this was truly a heroic accomplishment.
Maggie’s mother, Nancy, who gave me permission to tell her family’s story in my book, “Rights Come to Mind: Brain Injury, Ethics and the Struggle for Consciousness,”
never thought this would be how her daughter’s life would turn out. She
had other expectations for her beautiful daughter, who studied Spanish,
played Frisbee and aspired to be a veterinarian.
Still,
Nancy and Maggie made a life together after the stroke. And it was O.K.
Nancy was grateful that Maggie had learned to communicate, while
wishing she could do more than move that one eye. Still, she told me, it
seemed like it was “enough to have a life, even a small life.” Maggie
had things that many people didn’t have, she said — relationships,
friends and family who loved her.
In the end, Nancy arrived at a sort of acceptance: “So, I don’t know. But I think a small life is O.K.”
We
cannot know whether it was O.K. for Maggie. But the rudimentary
communication channel established with her left eye was the start of a
way to know what she might have thought. That we cannot yet know for
sure did not mean that she had no preferences or wishes. Indeed the goal
of those of us who do this work is to find out and try to provide these
patients with the chance to again express their agency.
Maggie’s case — her “small life” — became very consequential when my colleagues at Weill Cornell Medicine published a paper last December in the journal Science Translational Medicine
revealing what had happened within her brain following her injury.
During the recovery of her ability to communicate, Maggie’s brain
essentially rewired over a period of years.
Using
magnetic resonance imaging, Daniel J. Thengone, a graduate student, and
colleagues in the Laboratory of Cognitive Neuromodulation, led by Dr.
Nicholas D. Schiff, were able to demonstrate a strengthening of
structural and functional reconnections across the two hemispheres
emanating from Broca’s area, the region in the frontal lobe responsible
for speech. It showed, remarkably, that even a grievously injured brain
could heal itself. It appeared to do so by a process bearing a strong
resemblance to typical brain development. The ongoing reorganization of
connections among neurons is a reprise of how the developing brain gets
its start.
As
notable as these findings were, they did not stem from a high tech or
costly intervention. Instead, they were the byproduct of a mother’s
love, speech therapy and a simple eye-tracking device that cost about $30.
It was Freud’s “talking cure” in a modern guise, and no less
significant for our understanding of resilience and the importance of
interpersonal engagement.
Yet,
access to care is strained for this population. Utilization reviewers,
and insurance benefit companies will deny access to rehabilitation to
many individuals when they leave the hospital because they are deemed
not yet ready for rehabilitation. But when nearly half of those who
could participate are misdiagnosed as vegetative when they are actually
minimally conscious, this vulnerable group is further marginalized.
Organizations like the American College of Rehabilitation Medicine have
been calling for a comprehensive evaluation of patients after hospital
discharge so that misdiagnosis can be prevented and those who might be
helped can get the rehabilitation they need.
Even
those lucky few who do get rehabilitation and are not shunted off to
what is euphemistically called “custodial care” get too little time.
Most rehab stays are six weeks or less. But if the brain recovers
through a slow process similar to development, why do we provide — and
only to those lucky enough to receive it — just a few hours of
rehabilitation a week for six weeks? It would be akin to sending your
third grader to school for half-days of classes for a month or two and
telling them that they are now on their own. Now that we know that it
takes years for the developing brain to learn and mature, a similar
commitment to the recovering injured brain now seems indicated.
If
we reconceived rehabilitation as education, no one would graduate after
a six-week course of care. Instead, we would promote lifelong learning
as a means to achieve a recovered life. If there is a legal obligation
to educate the developing brain, should there not be a correlative
responsibility to those whose brain are in a process of redevelopment
and recovery?
These
are radical propositions at a time of fiscal scarcity and serious
debate about the fate of Obamacare and health care reform. Understood
this way, one might see the surrounding politics as untenable and
reasonably seek to spend resources elsewhere. But it would be a mistake
to view our responsibilities so narrowly. What is at stake here is more
than a simple insurance question or access to care. It is a more
fundamental question of basic civil rights, leaving conscious
individuals isolated and abandoned.
Tragically, the most fundamental rights have been have been denied patients in the minimally conscious state.
Take
pain control, for example. When a minimally conscious patient is
mistakenly diagnosed as vegetative and thus thought insensate, they may
not receive analgesic pain management or anesthesia for medical
procedures. If this occurs, they are incredibly vulnerable — unable to
communicate, and thus unable to cry out in pain. This error of omission
constitutes a disrespect for personhood that should be beyond the pale
in any civilized society.
Of
course, we can address this by better diagnostic assessments of a
patient’s brain state, to differentiate the minimally conscious from the
permanently unconscious patient. But we can do something more. We can
work to restore the patients’ own voices, so that they can tell us
whether they are in pain, and remind us that they are in the room. They
remain members of the human community even though society has segregated
them in chronic care.
I
use the verb “segregated” deliberately, to invoke a time when separate
but equal was the law. In the wake of legal advances like the Americans
with Disabilities Act and the United Nations Convention on the Rights of
the Disabled, which call for the integration of people with
disabilities into civil society, how is the pervasive segregation of
this population justified?
Part
of the problem is that when these laws were written, the notion of
reintegration was focused on physical mobility — the ramp on the side
walk and the accessible workplace. It wasn’t about people whose means of
integration required something more than a ramp. For minimally
conscious patients, the ramp is the restoration of functional
communication, which makes reintegration into its cognate — community —
possible. When we restore voice to these patients we bring them back
into the room and the conversation.
To
accomplish this we must consider the basic relationship between these
individuals and the state, and their civil rights as citizens. Legal
protections have eluded this population precisely because they have been
disenfranchised by their injury. They have fallen outside the scope of
legal protections and been subject to abuse and neglect.
This
is the civil rights issue most of us never thought about. But the long
arc of justice is sometimes refracted through scientific discovery and
medical advances.
I
often speak to university students brought up in the era of L.G.B.T.Q.
rights who can’t understand how my generation did not appreciate that
people could love those they chose to love. They find it
incomprehensible that this almost self-evident right had eluded earlier
generations. I caution against smugness, suggesting that their own
children may well ask them how they allowed society to ignore conscious
individuals and deprive them of their rights.
We
now can anticipate that there are large numbers of people like Maggie,
who have the potential to communicate but are sequestered — indeed,
segregated — in chronic care, isolated and abandoned by society. Some
could be identified with proper screening and coaxed back through
rehabilitation and emerging treatments. Now that we know this, we can’t
look away.

Thank you for posting this. People think PVS people just aren't in there and I have always believed they are, they just are trapped deep in their body.
