The Myth of Mental Illness - Genetics of Mental Health

Written by Sam Vaknin

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.

4. 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.

5. 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.

6. 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.

7. The Insanity Defense

"It is an ill thing to knock against a deaf-mute, an imbecile, or a minor. He that wounds them is culpable, but if they wound him they are not culpable." (Mishna, Babylonian Talmud)

If mental illness is culture-dependent and mostly serves as an organizing social principle - what should we make of the insanity defense (NGRI- Not Guilty by Reason of Insanity)?

A person is held not responsible for his criminal actions if s/he cannot tell right from wrong ("lacks substantial capacity either to appreciate the criminality (wrongfulness) of his conduct" - diminished capacity), did not intend to act the way he did (absent "mens rea") and/or could not control his behavior ("irresistible impulse"). These handicaps are often associated with "mental disease or defect" or "mental retardation".

Mental health professionals prefer to talk about an impairment of a "person's perception or understanding of reality". They hold a "guilty but mentally ill" verdict to be contradiction in terms. All "mentally-ill" people operate within a (usually coherent) worldview, with consistent internal logic, and rules of right and wrong (ethics). Yet, these rarely conform to the way most people perceive the world. The mentally-ill, therefore, cannot be guilty because s/he has a tenuous grasp on reality.
