Psychosurgery was developed early in human prehistory (trephination) as a need perhaps to alter aberrant behavior and treat mental illness. The “American Crowbar Case” provided an impetus to study the brain and human behavior. The frontal lobe syndrome was avidly studied. Frontal lobotomy was developed in the 1930s for the treatment of mental illness and to solve the pressing problem of overcrowding in mental institutions in an era when no other forms of effective treatment were available. Lobotomy popularized by Dr. Walter Freeman reached a zenith in the 1940s, only to come into disrepute in the late 1950s. Other forms of therapy were needed and psychosurgery evolved into stereotactic functional neurosurgery. A history of these developments up to the 21st century will be related in this three-part essay-editorial, exclusively researched and written for the readers of Surgical Neurology International (SNI).

TREPHINATION, SHAMANS, AND MENTAL ILLNESS
Trephination (or trepanation) of the human skull is the oldest documented surgical procedure performed by man. Trephined skulls have been found from the Old World of Europe and Asia to the New World, particularly Peru in South America, from the Neolithic age to the very dawn of history.[
Surely we can surmise that intractable headaches, epilepsy, animistic possession by evil spirits, or mental illness, expressed by errant or abnormal behavior could have been indications for surgical intervention prescribed by the shaman of the late Stone or early Bronze Age. Dr. William Osler asserted, “[Trephination] was done for epilepsy, infantile convulsions, headache and various cerebral diseases believed to be caused by confined demons to whom the hole gave a ready method of escape.”[
In ancient Greece and Rome, many medical instruments were designed to penetrate the skull. The Roman surgeons developed the terebra serrata, which was used to perforate the cranium by rolling the instrument between the surgeon's hands [
During the Middle Ages and the Renaissance, trepanation was performed not only for skull fractures but also for madness and epilepsy. There are telltale works of art from this period that bridge the gap between descriptive art and fanciful surgery. For example, we find the famous oil painting by Hieronymus Bosch (c. 1488-1516) that depicts “The Extraction of the Stone of Madness” [
For most of man's recorded history, the mentally ill have been treated as pariahs, ostracized by society and placed in crowded hospitals, or committed to insane asylums.[
THE “AMERICAN CROWBAR CASE”
The early concept of cerebral localization (i.e., aphasia, hemiplegia, etc.) was derived first from the study of brain pathology, particularly cerebral tumors and operations for their removal;[
In 1848, Phineas P. Gage, a construction foreman at the Rutland and Burlington Railroad, was severely injured while helping construct a railway line near the town of Cavendish, Vermont. The premature explosion propelled a tamping iron — a long bar measuring 3 feet 7 inches in length and 1.25 inch in diameter – through Gage's head. The 13.25 pound rod penetrated his left cheek, traversed the midline, the left frontal lobe, and exited the cranium just right of the midline near the intersection of the sagittal and coronal sutures [
The 25-year-old Gage survived, but the mental and behavioral changes noted by his doctor, friends, and co-workers were significant. From being a motivated, energetic, capable, friendly, and conscientious worker, Gage changed dramatically into an obstinate, irreverent, irresponsible, socially uninhibited individual. These changes in personality would later be recognized as the frontal lobe syndrome. In the case of Gage, these changes were noted almost immediately after the injury. Close attention was paid to the case by Gage's physician, Dr. John M. Harlow, not necessarily because of the personality changes but because the patient had survived such an extensive and serious injury and surgical ordeal.
The case received notoriety in the medical community when it was thoroughly described by Dr. Harlow 20 years later in an otherwise obscure medical journal. The doctor wrote: “Previous to his injury, although untrained in the schools, he possessed a well-balanced mind, and was looked upon by those who knew him as a shrewd, smart businessman, very energetic and persistent in executing all his plans of operation. In this regard his mind was radically changed, so decidedly that his friends and acquaintances said he was ‘no longer Gage.’”[
Dr. Harlow followed his patient's travels across North and South America, and when Gage died in status epilepticus in 1860 near San Francisco, the doctor was able to retrieve the exhumed skull and tamping iron. Gage had continued to carry the rod wherever he went, his “constant companion” [
THE FRONTAL LOBE SYNDROME AND THE DEVELOPMENT OF LOBOTOMY (C. 1935)
The historic operation that we can arguably describe as the first psychosurgery procedure was performed by psychiatrist Dr. Gottlieb Burckhardt (1836-1907) in Switzerland in 1888. Burckhardt removed an area of cerebral cortex that he believed was responsible for his patient's abnormal behavior. He followed this by performing selective resections mostly in the temporal and parietal lobes on six patients, areas in the lobes that Burckhardt considered responsible for his patients’ aggressive behavior and psychiatric disorder. His report was not well received by his colleagues and met with disapproval by the medical community. Subsequently, Burckhardt ceased work in this area.[
The Second International Neurologic Congress held in London in 1935 was a landmark plenary session for psychosurgery. American physiologist Dr. John F. Fulton (1899-1960) presented a momentous experiment in which two chimpanzees had bilateral resections of the prefrontal cortex. These operations were pioneering experiments in the field because the animals became “devoid of emotional expression” and were no longer capable of arousal of the “frustrational behavior” usually seen in these animals. The behavioral change was noted but the full implications were not. These findings would become very important decades later when social scientists in the 1970s noted that aggressive behavior and rage reaction were associated with low tolerance for frustration in individuals with sociopathic tendencies.[
This Congress was historic also because it was attended by personages who would leave marks in the history of psychosurgery, the neurosurgical treatment of mental disorders. Among the participants were two Portuguese neuroscientists: Dr. Antonio Egas Moniz (1874-1955), Professor of Neurology at the University of Lisbon, and his collaborator, the neurosurgeon Dr. Almeida Lima (1903-1985). They worked together in performing frontal leucotomies for psychiatric illnesses in the 1930s. In fact, Dr. Moniz's efforts supported the work of physiologist John Fulton that frontal lobe ablation subdued the behavior of aggressive chimpanzees. Also attending this Congress was American neurologist Dr. Walter Freeman (1895-1972), who would soon leave a big imprint in the march of psychosurgery in the form of the frontal lobotomies.[
But there was more. Dr. R. M. Brickner described a patient with bilateral frontal lobectomies for excision of tumor. Postoperatively his patient showed a lack or restraint and social disinhibition, providing further evidence of the frontal lobe syndrome.[
Frontal lobotomy, the sectioning of the prefrontal cortex, and leucotomy, the severing of the underlying white matter, for the treatment of mental disorders, reached a peak of popularity after World War II. But, as we have seen, development of this surgery began in the 1930s with the work of the celebrated Egas Moniz, who also made his mark in neuroradiology as the father of cerebral angiography [
It was at this time that a constellation of symptoms finally became associated with frontal lobe damage and removal – for example, distractibility, euphoria, apathy, lack of initiative, lack of restraint, and social disinhibition. Some of these symptoms were reminiscent of the personality changes noted by Dr. John M. Harlow in Phineas Gage nearly three quarters of a century earlier.
THE PROBLEM OF MENTAL ILLNESS IN THE EARLY 20TH CENTURY
It must be remembered that this movement toward surgical intervention did not occur in a vacuum. It was engendered at a time when drug therapy was not available, and it involved mostly severely incapacitated patients for whom psychotherapy was ineffective or unavailable. Physicians, particularly psychiatrists and neurologists, those directly taking care of these unfortunate patients, were pushed against the wall to come up with effective therapy to modify abnormal psychiatric behavior and ameliorate mental suffering.
The problem of the increasing number of mentally ill patients for which no effective treatment was available, except for long-term hospitalization and confinement, had been noted since the 19th century, and by the early 20th century the problem had reached gigantic proportions. Psychotropic drugs were not available until the 1950s, and in their absence, the only treatment options used in conjunction with long-term hospitalization were physical restraint with the feared strait jackets, isolation in padded cells, etc., – i.e., conditions almost reminiscent of the notorious Bedlam Hospital of 19th century London.
Recently, Dr. R. A. Robison and colleagues summarized the socioeconomic context in which psychosurgery was advanced in the late 1930s by citing a 1937 report on the extent of institutionalization of the mentally ill in the United States: “There were more than 450,000 patients institutionalized in 477 asylums, with nearly one half of them hospitalized for five years or longer.” The cost in today's dollars is estimated to have exceeded $24 billion.[
Psychotherapy, not to mention psychoanalysis, as proposed by Sigmund Freud (1856-1939), Carl Jung (1875-1961), and other prominent psychiatrists, was beyond the reach of most patients afflicted with psychiatric disorders until much later in the century. Advances in medicine and psychiatry in the latter part of the century would bring relief to untold millions but many problems even then would still persist.[
The leading lights of psychiatry at the turn of the century, Austrian psychoanalyst Sigmund Freud and German psychiatrist Emil Kraepelin (1856-1926) had conflicting approaches to mental illness. Freud recommended psychotherapy, often ineffective, almost always unfeasible in severely mentally ill patients, in which diseases ranged from tertiary syphilis and severe anxiety-neuroses to agitated depression and schizophrenia. Kraepelin, in contrast, preferred more aggressive intervention with electroconvulsive therapy (ECT) and insulin shock therapy [
SURGERY OF THE FRONTAL LOBES – LEUCOTOMY AND LOBOTOMY (c . 1935-1955)
So it was in the mid 1930s under the circumstances of ineffectual treatments and hospital overcrowding that Moniz and Lima began to collaborate and carry out their work in Lisbon, Portugal. They developed the frontal leucotomy (or leukotomy), sectioning the white matter connections between the prefrontal cortex and the thalamus. First, they used alcohol injections; subsequently they introduced the leucotome and termed the procedure frontal leucotomy. They reported that their patients were more calm and manageable but their affect more blunted after the operations.
In the United States, Dr. James W. Watts (1904-1994), a neurosurgeon at George Washington University, was invited to collaborate with American neurologist and neuropathologist Dr. Walter Freeman (1895-1972) in developing the transorbital lobotomy in the early 1940s [
They performed the first frontal lobotomy in the U.S. in 1936 the same year Moniz presented his series of 20 patients from Portugal. With his knowledge of neuropathology, Freeman was able to visualize and analyze retrograde degeneration in postmortem examination of patients who had undergone the procedure and died later. He modified Moniz's leucotome for better precision in targeting specific frontal lobe-thalamic tracts. Patients with affective disorders had their leucotomy more anterior, whereas in those afflicted with more severe schizophrenic symptoms the lobotomy was more posterior.
In 1942, Freeman and Watts published the first edition of their classic monograph Psychosurgery and reported on 200 patients: 63% were improved; 23% had no improvement: and 14% were worsened or succumbed to their surgery.[
Freeman had used alcohol injections initially in some of his lobotomies, but he subsequently modified his procedure of transorbital leucotomy by using a modified ice-pick instrument to traverse the roof of the orbit and enter the base of the skull. This was frequently done with local anesthesia or with sedation following ECT. The orbitoclast was then inserted to a depth of 7 cm at the base of the frontal lobes and swept 15° laterally.[
Nevertheless, Freeman and Watts parted and went separate ways. Freeman became a relentless crusader and performed over 4000 lobotomies. Robison et al. thus summarized the situation in a recent review article: “Despite resistance and reservations in the broader medical community, many psychiatrists and nonsurgical practitioners seized on the procedure as a new last resort for patients who lacked any effective alternate treatments.” Frontal lobotomy became a widely used procedure in the U.S., and an estimated 60,000 procedures were performed in the U.S. and in Europe between 1936 and 1956.[
By 1952, one of the pioneers of psychosurgery, the famed American physiologist John Fulton, was announcing the end of lobotomy and ushering in the beginning of stereotactic and functional neurosurgery because of improved precision and less cerebral tissue ablated. Chlorpromazine, which had been introduced in Europe in 1953, became available in the U.S. in 1955; haloperidol followed in 1967, and the drug therapy revolution was now also underway.[
SOCIOECONOMIC ASPECTS OF MENTAL ILLNESS AND INSTITUTIONALIZATION
The need to modify abnormal behavior and ameliorate mental suffering persists in our time. It has been estimated that 5 out of 10 cases of disability worldwide are attributable to mental disorders. And major depression heads the list of these psychiatric or psychological disorders with an incidence of 12-18% projected for the lifetime of the individual of the 21st century.[
Despite psychotropic drugs, ECT, lobotomy, and psychosurgery, the societal problems posed by the prevalence of mental illness persist to this day. The steady institutionalization of the 1930s was followed by rapid deinstitutionalization in the 1970s. In 1963, U.S. President John F. Kennedy proposed a program for dealing with the persistent, unresolved problems of the mentally ill and the growing socioeconomic concerns of their long-term institutionalization. Kennedy called for the formation of community mental health centers (CMHCs) funded by the federal government. Outpatient clinics replaced state hospitals and long-term institutionalization. Over the next 17 years, the federal government funded 789 CMHCs, spending $20.3 billion in today's dollars. “During those same years, the number of patients in state mental hospitals fell by three quarters – to 132,164 from 504,604,” laments Dr. E. Fuller Torrey, a noted psychiatrist and schizophrenia researcher. And he adds: “Those beds were closed down.”[
In the ensuing half century, these patients were discharged onto the streets of America, without family support and suffering from severe mental illness — including schizophrenia, bipolar and personality disorders, and criminal insanity. Half of them fare poorly.[
And so the problem of mental illness persists, influenced more by politics than mental health data and sound criminologic and sociologic scholarship.[
The social sciences in general and psychiatry in particular, despite the continued technological advances of our computer age, have not been able to keep up with the mounting psychological problems associated with this societal progress. Violent and criminal behavior, particularly when associated with repetitive, unprovoked aggression and low threshold rage reactions, also appear to be pernicious and recalcitrant elements of modern society, elements that have been difficult to explain and solve by our social scientists. Part 2 discusses new forms and methods of psychosurgery via stereotactic functional neurosurgery and advances in neuroscience. Part 3 will conclude the essays.
