COMMENTARY

The next time one of psychiatry’s detractors tells you that psychiatrists do not treat real diseases because we have not identified the precise pathophysiology of schizophrenia, bipolar disorder, or other psychiatric illnesses, try this: Ask the skeptic to explain the precise pathophysiology of migraine or cluster headaches. Follow up by asking what laboratory test or neuroimaging study neurologists use to diagnose these devastating conditions. At that point, the critic should be either blushing or blanching.

For the coup de grace, ask them why the late Thomas Szasz, MD—who insisted that real diseases always entail the identification of specific morphological or physiological abnormalities—did not write a book titled The Myth of Migraine as a sequel to his famous (or infamous) 1961 work The Myth of Mental Illness. (Disclosure: Szasz was one of my teachers during residency and an intellectual fencing partner—our mutually agreed-upon term—for decades afterward).1,2

Of course, most Psychiatric TimesTM readers will know that the precise pathophysiology of migraine and cluster headaches is not known, despite notable advances in our understanding; and that there is no laboratory test or neuroimaging study that reliably or usefully identifies these conditions.3,4 Both diagnoses are made largely on the basis of the patient’s subjective report and the exclusion of other neurological causes. (Cluster headaches are often, but not always, associated with ipsilateral cranial autonomic signs, such as eyelid edema or facial flushing).3,4 As for Szasz and migraines, to the best of my knowledge, he never disputed the reality of this affliction, even though its precise pathophysiology remains incompletely understood.

Pain as Sharp as a TAC

Let us take note of the excellent piece by journalist and headache sufferer Tom Zeller Jr, who recently described his own struggles with cluster headaches.5 Technically, these are a subset of a group of conditions known as the trigeminal autonomic cephalalgias (TACs). Although this hifalutin name may suggest that scientists have pinned down the etiology and pathophysiology of TACs, this is simply not the case.

To be sure, plausible theories abound, including, most recently, linking TACs to “dysfunction in the trigeminal and cranial autonomic systems and their connections, modulated by the hypothalamus.”4 Yet, as headache specialist Stephanie J. Nahas, MD, has acknowledged, “The pathophysiology of TACs is complex and incompletely understood.”4 And, as a rule, morphological and anatomical abnormalities in the brain are lacking in TACs; for example, investigation rarely yields abnormalities on magnetic resonance imaging or computed tomography imaging. (However, vascular loop compression and pituitary abnormalities are sometimes found in patients with short-lasting, unilateral neuralgiform headache attacks or SUNHA.4) Furthermore, to my knowledge, TACs are never noted on autopsy reports, contrary to Szasz’s erroneous claim that “Every ‘ordinary’ illness that persons have, cadavers also have.”6

TACs are Disease States

And yet, the term disease may reasonably be applied to the TACs, which Nahas has called, “a distinct set of headache diseases.”4 This is so, even though, as Zeller rightly noted, “any neurologist working today will readily admit that we remain the in the Stone Age with regard to many aspects of these most common disorders.”5

Similarly, the term disease may reasonably be applied to schizophrenia, bipolar disorder (BD), and other incapacitating psychiatric afflictions, even though the etiology and pathophysiology of these heterogeneous conditions are not yet well understood. There are, however, hundreds of studies showing a variety of morphological and physiological abnormalities in both schizophrenia and bipolar disorder.7,8

Disease and Clinical Medicine

By and large, physicians are a practical lot, anxious about evaluating everybody sitting in their overcrowded waiting rooms. Most physicians do not scratch their heads, pondering the question, “Will my next patient have a disease, a disorder, a malady, an illness, a morbus, an affliction, or a syndrome?” The subtle differences among these terms are of far less clinical importance than the presence of substantial and/or enduring suffering and incapacity in the patient—arguably, the hallmarks of disease (dis-ease) as commonly understood throughout the long history of clinical medicine.1,2,9,10 (I am well aware that not all states of suffering and incapacity are ordinarily viewed as disease, including instances of torture, physical or psychological abuse, and the like).

Cluster headaches and related diseases certainly fit the criteria of substantial and/or enduring suffering and incapacity; indeed, cluster headaches are ominously known as suicide headaches.4 It hardly needs mentioning that serious psychiatric disease states like schizophrenia, BD, and various psychoses also produce substantial and/or enduring suffering and incapacity—and all too often lead to suicide.11

Citing the work of sociologist Joanna Kempner, PhD, Zeller noted that migraine headaches, in particular, “have been given inadequate consideration by the medical and scientific establishments,”5 which Kempner attributed partly to the disproportionate number of women afflicted by migraines. Ironically, Zeller noted, their physical pain “was often ascribed a psychological or emotional origin.”5

Like the TACs described by Zeller, psychiatric disease is too often dismissed or disparaged, and psychiatric patients are often inadequately assessed in some medical settings.12 Sadly, this is due in part to the influence of Szasz and others who have relegated psychiatric diseases to the status of myths, problems in living, or—as Szasz once argued—forms of lying.13

Despite Szasz’s widespread influence, his ideas have come in for heavy criticism. For instance, psychiatrist Tony Benning, MBChB, MSC, MRCPsych, FRCPC, PhD, summarized the views of another psychiatrist, R.E. Kendell, MD14:

As Kendell pointed out in his rebuttal of Szasz’s claim that mental illnesses fail to conform to the definition of disease, Szasz’s notion of disease, influenced by [Rudolph] Virchow, was overly narrow, for it placed excessive importance on the criterion of ‘cellular pathology.’ Kendell also claimed that Szasz’s argument understated the extent to which ‘suffering and incapacity are fundamental attributes of disease’. He brought attention to the fact that in medicine generally there is no universally agreed upon definition of disease, and if Szasz’s criterion were to be widely adopted, several diseases widely recognized in medicine, such as migraine and torticollis (neither of which [is] associated with lesions or cellular pathology) would fail to qualify.

Concluding Thoughts

The term disease is defined in many different ways, depending on the needs, training, and expertise of the observer. For the pathologist, the term generally means something quite different than what it represents for the primary care physician, the epidemiologist, or the forensic psychiatrist. Yet one thing is clear: Physicians in general view disease in pragmatic and humanistic terms, applying the term to a very broad spectrum of human suffering and incapacity. One remarkably sweeping definition was provided in no less a source than the 8th edition of Harrison’s Principles of Internal Medicine15 (italics added for emphasis): “The clinical method has as its object the collection of accurate data concerning all the diseases to which human beings are subject; namely, all conditions that limit life in its powers, enjoyment, and duration.”

Just as we recognize trigeminal autonomic cephalalgias as instantiations of disease, so too must we recognize the most serious psychiatric conditions as disease states. And just as patients with TACs must be taken seriously, so too must those afflicted by psychiatric disease.
