IV. The Biochemistry and Genetics of Mental Health
Certain mental health afflictions are either correlated with a statistically abnormal biochemical activity in the brain - or are ameliorated with medication. Yet the two facts are not ineludibly facets of the same underlying phenomenon. In other words, that a given medicine reduces or abolishes certain symptoms does not necessarily mean they were caused by the processes or substances affected by the drug administered. Causation is only one of many possible connections and chains of events.
To designate a pattern of behaviour as a mental health disorder is a value judgment, or at best a statistical observation. Such designation is effected regardless of the facts of brain science. Moreover, correlation is not causation. Deviant brain or body biochemistry (once called "polluted animal spirits") do exist - but are they truly the roots of mental perversion? Nor is it clear which triggers what: do the aberrant neurochemistry or biochemistry cause mental illness - or the other way around?
That psychoactive medication alters behaviour and mood is indisputable. So do illicit and legal drugs, certain foods, and all interpersonal interactions. That the changes brought about by prescription are desirable - is debatable and involves tautological thinking. If a certain pattern of behaviour is described as (socially) "dysfunctional" or (psychologically) "sick" - clearly, every change would be welcomed as "healing" and every agent of transformation would be called a "cure".
The same applies to the alleged heredity of mental illness. Single genes or gene complexes are frequently "associated" with mental health diagnoses, personality traits, or behaviour patterns. But too little is known to establish irrefutable sequences of causes-and-effects. Even less is proven about the interaction of nature and nurture, genotype and phenotype, the plasticity of the brain and the psychological impact of trauma, abuse, upbringing, role models, peers, and other environmental elements.
Nor is the distinction between psychotropic substances and talk therapy that clear-cut. Words and the interaction with the therapist also affect the brain, its processes and chemistry - albeit more slowly and, perhaps, more profoundly and irreversibly. Medicines - as David Kaiser reminds us in "Against Biologic Psychiatry" (Psychiatric Times, Volume XIII, Issue 12, December 1996) - treat symptoms, not the underlying processes that yield them.
V. The Variance of Mental Disease
If mental illnesses are bodily and empirical, they should be invariant both temporally and spatially, across cultures and societies. This, to some degree, is, indeed, the case. Psychological diseases are not context dependent - but the pathologizing of certain behaviours is. Suicide, substance abuse, narcissism, eating disorders, antisocial ways, schizotypal symptoms, depression, even psychosis are considered sick by some cultures - and utterly normative or advantageous in others.
This was to be expected. The human mind and its dysfunctions are alike around the world. But values differ from time to time and from one place to another. Hence, disagreements about the propriety and desirability of human actions and inaction are bound to arise in a symptom-based diagnostic system.
As long as the pseudo-medical definitions of mental health disorders continue to rely exclusively on signs and symptoms - i.e., mostly on observed or reported behaviours - they remain vulnerable to such discord and devoid of much-sought universality and rigor.
VI. Mental Disorders and the Social Order
The mentally sick receive the same treatment as carriers of AIDS or SARS or the Ebola virus or smallpox. They are sometimes quarantined against their will and coerced into involuntary treatment by medication, psychosurgery, or electroconvulsive therapy. This is done in the name of the greater good, largely as a preventive policy.
Conspiracy theories notwithstanding, it is impossible to ignore the enormous interests vested in psychiatry and psychopharmacology. The multibillion dollar industries involving drug companies, hospitals, managed healthcare, private clinics, academic departments, and law enforcement agencies rely, for their continued and exponential growth, on the propagation of the concept of "mental illness" and its corollaries: treatment and research.
VII. Mental Ailment as a Useful Metaphor
Abstract concepts form the core of all branches of human knowledge. No one has ever seen a quark, or untangled a chemical bond, or surfed an electromagnetic wave, or visited the unconscious. These are useful metaphors, theoretical entities with explanatory or descriptive power.
"Mental health disorders" are no different. They are shorthand for capturing the unsettling quiddity of "the Other". Useful as taxonomies, they are also tools of social coercion and conformity, as Michel Foucault and Louis Althusser observed. Relegating both the dangerous and the idiosyncratic to the collective fringes is a vital technique of social engineering.
The aim is progress through social cohesion and the regulation of innovation and creative destruction. Psychiatry, therefore, is reifies society's preference of evolution to revolution, or, worse still, to mayhem. As is often the case with human endeavour, it is a noble cause, unscrupulously and dogmatically pursued.
