cosmetic neurology

This is an interesting paper by Dr. Chaterjee, a very well respected neurologist. I find this subject matter endlessly fascinating, ultimately I do not think there is a difference between therapy and enhancement but in their use. I put my perspective/comments in green!

Basic neuroscience and neuropharmacology are beginning to yield therapies for cognitive disorders. While we can eagerly anticipate treatments for dementing illnesses, stroke, traumatic brain injury, and developmental abnormalities, these very treatments raise uncomfortable questions. If we can improve cognitive systems in disease, can we also do so in health? Should we practice cosmetic neurology?


I do not agree with the set up because it frames anything outside of treating an acute decrease in health, i.e. -disease, as "cosmetic". The word cosmetic is taken from the greek kosmetikos, meaning to adorn, that usage connotes a preoccupation with the exterior. I believe improving our cognitive systems is the same as "improving" our blood pressures, nutrition, or life spans.


The possibility of “better brains” has captured the imagination of the press, policy pundits, and ethicists [1-10]. With few exceptions, physicians have not contributed to these discussions, despite their central role in this unfolding drama [11,12]. Cosmetic neurology includes the use of botulinum toxin to brush away wrinkles.


I'll agree, using botox for wrinkles seems less "necessary" than using it for migraines or dystonias.


However, it also alters how we function and feel, rather than just how we look. Many interventions to improve cognitive and emotional systems are available now, and others are on the horizon. The risks and benefits of newer medications remain to be worked out. However, we can assume that some version of these medications will be relatively efficacious and safe. The accompanying article on neuroethics by Martha Farah reviews the anticipated pharmacopeia of cosmetic neurology and the deep ethical concerns raised for individuals and society (also see [12]). The focus here is on the role of the physician in managing the use of cosmetic neurologicinterventions.


Framing the Issue: the Purpose of Medicine

Ethical discussions of cosmetic neurology often frame the issue as one of therapy versus enhancement [6,13]. Therapy treats disease and enhancement improves normal abilities. Most people consider therapy desirable. By contrast, many pause at enhancement. Francis Fukayama, for example, opines, “the original purpose of medicine is to heal the sick, not turn healthy people into gods” [14].

So I'll take issue with Fukayama's quote, which in my opinion is hyperbole. I believe the underlying assumption that guides an ethical pursuit of enhancement is that mankind is mortal and can never be "gods" moreover that is not the purpose of improving "normal" function. The purpose for improving normal function is create opportunity for the growth, development, and evolution of our existence. Also, "normal" is a statistical measure of central tendency, it is descriptive- think how the "normal" human lifespan has improved over the last millennia, no one argues against pursuing this similar "enhancement". Again "healthy" people are defined by their state of health, derived from heilen, meaning "whole", but that definition does not indicate what the whole is.


He suggests that public policy should restrict research for enhancement.

...and as a consequence risk falling behind those that do.


For 2 reasons, the distinction between therapy and enhancement is less useful than one might hope. First, notions of disease often lack clear boundaries. For example, if individuals of short stature can be “treated” with growth hormone [15], does it matter whether they are short because of a growth hormone deficiency or because of other reasons [13]?

I agree, in most cases no- it would not matter.


Second, promoting research for therapy and restricting it for enhancement ignores the simple fact that research in one often applies to the other. The therapy versus enhancement distinction also obscures what for physicians may be the critical question:

What is the purpose of medicine? The strength of allopathic medicine has been its scrutiny of disease mechanisms. Understanding the biology of malfunction provides insight into how to fix that malfunction. Despite its undoubted successes, this approach has limits. Most notably, the quality of patients' lives does not always correspond well to biomarkers and symptoms of disease. The symptoms of Parkinson's disease that are most responsive to dopamine agonists are not those that bother patients most [16]. Measures of disease activity may not be the best indicator of the impact of multiple sclerosis on patients [17]. Recognizing the limits of clinical and pathological indices, assessing patients' quality of life is now a routine practice in therapeutic trials. Such assessments seem eminently reasonable. After all, the point of treating a disease is to improve patients' quality of life. However, if a purpose of medicine is to improve quality of life

for people who happen to be sick, then why not apply medical knowledge to improve the quality of life of those who happen to be healthy?


Inevitability

Cosmetic neurology raises several serious ethical concerns. These interventions challenge fundamental notions of character and individuality; it is likely that they will be used coercively, and cosmetic neurology will not lessen the burden of distributive justice in a country in which the quality of health care is polarized by economic class. It is improbable, however, that cosmetic neurology will be restrained significantly by journalistic consternation, religious admonition, and government regulation. More likely, such restraints will be overwhelmed by free markets and military innovations.

Excellent paragraph, issues of coercion and distributive justice must be addressed but are not grounds for restricting the investigation into the field. I think what has come from

the field of reproductive endocrinology can inform how we implement advances in this field.


The market.

Pharmaceutical companies stand to make substantial profits and will probably support social pressures that encourage wide use of cosmetic neurology. According to Carl Elliott, in 2001 GlaxoSmithKline spent $91 million dollars in direct advertising to consumers for its medication Paxil [8], more than Nike spends on its top shoes. Advertisements for better brains would undoubtedly prey on an insecure public. Gingko Biloba, despite underwhelming effects on cognition [18], is a billion dollar industry. Pharmaceutical companies are not oblivious to the marketing possibilities of new “interventions” that could apply to the entire population [19, 20]. Sadly, the academy is unlikely to restrain Industry.

But I don't think this is the academy's role.

Scientific leaders who discover new therapeutic possibilities are quick to stake biotech claims [20]. Joint ventures between universities and pharmaceutical companies are increasingly common.


The military. Imagine a soldier who is stronger, faster, more enduring, learns more quickly, needs less sleep, and is not hampered by disturbing combat memories. The military's deep interests in cognitive enhancements date back to “go-pills” (amphetamines) for World War II soldiers [20], and continue to the present [20, 21]. For example, military investigators found that modafinil [a wakefulness-promoting agent] has its greatest effects in helicopter simulation performances at the combined nadir of sleep deprivation and circadian troughs [22]. Relevant findings from military research are likely to trickle down to civilians. Over-fed Hummer vehicles maneuver through the cobbled streets of Philadelphia. Perhaps Hummer brains are around the corner.


Seems a bit glib, lots of great technologies had their roots in the military, the internet -for one. Hummers were originally popularized by a movie actor and civilian, Arnold Schwarzenegger, and this was long before the masses used these vehicles as a proxy for their manhood.


The Role of Physicians

Americans believe that the pursuit of happiness is an inalienable right. This pursuit assumes we know what constitutes happiness [23]. Fame and fortune have been standard proxies for happiness in American culture. Better brains may very well join the list, either as a means to fame and fortune or as a direct source of happiness [24]. Scientific, economic, marketing, and regulatory forces are likely to shape the role physicians will play. The details are difficult to predict, but what is certain is that physicians will engage in cosmetic neurology.

Again, I take issue with calling this practice "cosmetic neurology", these issues are much deeper than that!


This practice will be complicated by the fact that physicians will not be able to rely on the conventions of traditional practice. Neurologists may have special understanding of the potential risks and benefits of quality of life interventions that work through the nervous system, but they have no special insight into the underpinnings of happiness. One plausible scenario is that physicians will become quality-of-life consultants.

But I would posit that the physician as quality of life consultant is already the case in many specialties. In past eras physicians once even had moral authority to say what is right and wrong. For these reasons I do not believe that we will be able to rely on conventions of practice.


Physicians might offer a menu of options, with the likely outcomes and the incumbent risks stated in generalities. The role would be to provide information while abrogating final responsibility for decisions to patients.

This reminds me of a lecture during 2nd year of medical school discussing the new paradigm in American healthcare writ large. The demise of paternalistic medicine gave rise to the autonomous patient and the "provider" (read technician, not physician) role being as stated above. The meat of Dr. Chatterjee's statement I believe is the physician abrogation of final responsibility. This is akin to "buck passing" and its a phenomenon in the new era of medicine that I believe is creating major identity problems for physicians. When I was and when I will again be the patient, I want a physician who takes final responsibility for my health, it is the physician opinion that I want. So when a patient asks, "do you think i should take this pill to make me smarter?", in addition to informing risks/benefits I would take a stance, "I think you should/should not... because...xyz, and that is my medical opinion."


Abrogation of such responsibility is promoted by current practice norms. Financial incentives in medicine are now driven by paper trails and diagnostic studies, rather than by personal engagement with patients.

Sad but true and hopefully unsustainable in the long run.


A comfortable stance would be to let people decide for themselves. After all, isn't autonomy what patients want? It turns out that the degree of autonomy patients want is not so clear, especially when they are sick (as reviewed in [25]). Furthermore, the bewildering array of choices available to American consumers in almost every domain of life is a source of considerable anxiety [26 ]. A practice of medicine that encourages patients to be consumers is in danger of compounding these anxieties. I am not advocating that physicians become disengaged purveyors of quality-of-life elixirs. I am suggesting that this role is a distinct possibility given current trajectories of medical practice. In a litigious society, many physicians would gladly shed the irksome traditional mantle of beneficence.


Where do you stand?

Since 1997, the FDA has permitted direct marketing to consumers. Physicians can anticipate facing questions from “patients” and advocacy groups in which distilling principle from prejudice is not easy. To make these issues concrete, I invite readers to consider the following questions.


1. Would you take a medication with minimal side-effects half an hour before Italian lessons if it allowed you to learn the language more quickly?

Market cap $25billion.


2. Would you give your children a medication with minimal side-effects half an hour before piano lessons if it allowed them to learn better?

Not until long term data came out about safety and adverse events with respect to their growth and development. e.g. - stimulants used as treatment for ADHD were found to make kids physically smaller (height and weight) at 10/20 yr follow up. Second, the child can decide for themselves when they are no longer a minor. It could be argued that having a beer or beta blocker before recital may make them perform better, but no one is credibly supporting that idea in a child either.


3. Would you pay more for flights whose pilots were taking a medication that made them react better in emergencies?

I would be happy to if it was shown to reduce the risk of death.


4. Would you want residents to take medications after call nights that would make them less likely to make mistakes in caring for patients because of sleep-deprivation?

Planning on at least trying this, but I believe (anecdotally) that one will eventually need to pay the sleep debt. I think that would be a great investigation, whether or not these medications reduce errors resulting from sleep deprivation. But I think another question in this debate is whether we should treat sleep deprivation, or prevent it!


5. Would you take a medicine that selectively dampened disturbing memories?

Great question!! Maybe...


This article has put forward legitimate concerns regarding the ethical practice of medicine where it relates to improving the healthy. For me, there have yet to be any convincing arguments against

the use and development of enhancing agents save for adverse events. Maybe one question worth asking is, given that these agents are not good or bad except for how they are used, would it be

right to use them knowing that most use could be "bad"?


This is such an exciting topic,
