In The Order of Things, Michel Foucault, the great French philosopher
cites a ‘certain Chinese encyclopedia’ that notes ‘animals
are divided into: (a) belonging to the Emperor, (b) embalmed, (c) tame, (d)
suckling pigs, (e) sirens, (f) fabulous, (g) stray dogs, (h) included in the
present classification, (i) frenzied, (j) innumerable, (k) drawn with a very
fine camelhair brush, (l) et cetera, (m) having just broken the water pitcher,
(n) that from a long way off look like flies’. The contemporary reader may look
on at this classification of animals with amusement and bewilderment or
contempt and derision. Yet, the same level of sophistication bedevils our
classification of morbid mental life today, as cataloged in the Diagnostic and Statistical Manual of Mental
Disorders, the official psychiatric bible. This cultural document, its
current permutation a product of fin-de-siècle America, holds up emotions,
behaviors, and beliefs deemed pathological as if they exist in external nature
as timeless, universal ‘things’ and aims to define and classify them.
Attempting to avoid any reference to the causal basis of the disorders listed
within, it also ignores the values, meanings, and assumptions imbued within the
system of classification or the context in which these ‘disorders’ are
experienced. About to enter its fifth revision, the DSM has been encircled in
debates regarding which elements of mental life should be recognized as morbid,
which disorders should bow their farewell, and where the disorders that are
included should be classified. These debates miss the point. Without
acknowledging the inherent meaning making in any system of classification, and
the context in which mental life is defined as disorder and then categorized,
the book is not only not valid, it is not useful.
A Brief History of Psychiatric
Classification
Attempts
at classifying elements of morbid mental life are not new. The first known
system dates back to 1400 BCE India, and the Ayurveda, which regarded aberrant
mental states as resulting from different forms of possession. In the West,
Hippocrates, Arataeus of Cappadocia, and Galen also tried their hand at
categorizing madness. Nor were they the only ones. Throughout the intervening
years a number of physicians, philosophers and theologians delineated their own
classifications of mental disorder. It was not until the 19th
century, however, that classifications of mental disorder came from careful
observation of the apparent causes, clinical course, and prognosis to
differentiate different forms of madness. Esquirol, more than anyone ushered in
this era and noted five types of madness including lypemania (melancholy),
mania, monomania, dementia, and idiocy. It was the German Psychiatrist Emil
Kraepelin though that made the most detailed study of the classification of
mental disorder, which was his life’s work and he refined his classification over
eight editions of his famous Textbook of Clinical
Psychiatry. The final classification included mostly medical problems
including traumatic brain injury, epilepsy, syphilis, intoxication, infection,
thyroid disease, and abnormal mental states in the context of brain disease.
His most enduring contribution to psychiatry was taking the “amorphous mass of
madness”* that existed before and separating it into manic-depressive insanity
(which includes depression and bipolar states today), and dementia praecox
(today’s schizophrenia). Dementia praecox was further divided into the
hebephrenic, catatonic, and paranoid types. Amazingly, Kraepelin’s
classification is the basis for our current psychiatric classification some 90
years later.
Why
this long trend in classifying pathological mental states? By defining the
unknown, and classifying psychopathology, we bring an element of knowability to
that which we do not know. Further, we create the illusion and indulge in the
deception of knowing more about that which we do not know than we do. It is
only natural that humans should try to reason with unreason, to order to
disorder, to dispassionately delineate the boundaries between sanity and
madness. It is ironic then, that this attempt at understanding and demystifying
abnormal mental states, should have compounded the sense of otherness and
alienation endured by those experiencing mental distress.
Is depression even a mood
disorder?
The
DSM attempts to catalog different aspects of mental life together that share
some element of commonality. For example, depression and mania are classified
as mood disorders, whilst generalized anxiety disorder, specific phobia, and
social phobia are classified as anxiety disorders. It would seem to make
intuitive sense to file major depressive disorder under the rubric of mood
disorders, and generalized anxiety under the rubric of anxiety disorders. It’s
in the names after all. When we come to closer inspect the experience that is
labeled as depression in the DSM, we discover that one does not even need to
experience depressed mood to be diagnosed with depression. For many people, the
experience is instead characterized by the inability to derive any joy from
their existence, from persistent feelings of stress and worry, endlessly
ruminating about the past, feelings of inadequacy, self-loathing and
worthlessness. It is almost as if the experience of ‘depression’ for these
individuals is summed up by thinking too much. Indeed, the concept of
depression does not exist for the Shona people of Zimbabwe. Instead, what would
get labeled as depression in the West is called Kufungisisa in Zimbabwe, which
means, “thinking too much”. For others the experience of depression is not
characterized by thinking too much or depressed mood. It is instead felt as a
profoundly visceral sapping of the
vital forces, of unending fatigue,
heaviness, nausea, malaise, tinnitus, and unexplained aches and pains. The
appetite has waned, sleep sparse and fitful. It is an extremely physical experience.
In China, the concept of depression does not exist, and despite attempts to
make the diagnosis, it is not accepted. Instead, what would be understood as
depression in the West is diagnosed as neurasthenia. Once regarded as an
American disease, today it has been expunged from the American psychiatric
classification as if it never existed. Even the selection of a particular
aspect of mental experience as a hallmark as a whole category of disorders is a
cultural act, laden with assumptions.
That
generalized anxiety disorder should be grouped with other anxiety disorders and
not depression is also more puzzling than might appear. For the Shona people of
Zimbabwe, the idea of “thinking too much” might equally be diagnosed as
generalized anxiety disorder or major depression in the West. It turns out
there is so much overlap between the two experiences, that the idea of
mixed-anxiety and depression is a common one in primary care. Intriguingly,
this overlap was not always the case. In the previous edition of the DSM,
generalized anxiety disorder had different diagnostic criteria altogether.
Instead of focusing on symptoms of worry, or constructing anxiety in cognitive
terms, generalized anxiety disorder was a fear-based diagnosis, constructed in
somatic terms. The experience was seen as characterized by persistent sweating,
shakiness, tremulousness, being on edge, experiencing palpitations,
breathlessness, a sinking sensation in the stomach, a sense of impending doom.
Just as neurasthenia (a physical experience and diagnosis) was supplanted by
the more psychologically experienced depression, a somatically or fear-based
anxiety disorder, has been supplanted by a more psychologically experienced
anxiety disorder. As we become more psychologically minded, the way we
experience distress is transformed from a somatic idiom to a psychic one.
The Problem with Psychiatric
Classification
The
process of psychiatric classification is weaved together with the assumption
that with each new edition some new truth has been discovered, a new disorder
unveiled, the boundaries between mental health and mental illness more firmly
delineated, that the process is the result of scientific progress. But as
Foucault demonstrated throughout his life, what appears as progress in seeing
the world are merely different ways of seeing, they are not necessarily better.
In the pursuit of scientific progress, our system of psychiatric classification
has attempted to uniformly describe the acceptable ways in which one can go
mad, as if to lose one’s mind was a uniform, discrete experience discontinuous
from the experiences of sadness, joy, fear, disgust, and terror we experience
in our daily lives. A psychiatric classification that ignores the wider
sociocultural forces at work rather than taking these to the heart of the
matter is woefully misguided. A psychiatric classification that attempts to
homogenize madness, rather than accept the enormous variation in the experience
of mental distress and the process of meaning making has missed the point. I
will continue to dutifully document my multi-axial diagnoses in my notes. But
like the DSM, my notes will be most salient not for what has been written, but
for what has not been written.
