Antonio Moniz: The Man Behind Psychosurgery by https://padlet.com/gray1501/3lo5t845c78ev4qx en-us 2023-02-22 21:10:49 UTC 2023-02-22 22:31:23 UTC hello@padlet.com Trepanation as the start of it all gray1501 https://padlet.com/gray1501/3lo5t845c78ev4qx/wish/2491737814 As discussed in class, trepanation was the first invasive surgery used to alleviate symptoms of the mind. This later was extended to individuals who suffered mental symptoms, including hysteria. This procedure dates all the way back to the Neolithic age, the B.C. era1. Doctors used this treatment to alter human behavior1. At this time, evil spirits were a popular reason why trepanation was used as individuals believed these spirits could be relieved by making a hole in the skull that allowed them to escape. Epilepsy, headaches, and other abnormal behavior patterns were also some other reasons why trepanation was used1. Despite the fact that many physicians and philosophers believed the soul lay in the heart, this procedure was one of the first methods to support that the behavior might be a result of what is going on in the mind, which rested in the head, even though this ideology was not accepted until later. There was an unconscious agreement that by trying this procedure, there could be a possibility that the soul and mind connected. Unfortunately, there are very few records on the improvement or decline of the symptoms experienced by patients, but nonetheless, the procedure was tried1.

In the late 5th century of the B.C. era, after trepanation was used, Hippocrates came along to describe what would be called the humoral theory1. Hippocrates was one of the first physicians to acknowledge the fact that maybe there was a physical explanation for something not so tangible: the mind and behavior. He established four humors: black bile, yellow bile, blood, and phlegm1. Each of these was connected to the four elements of the earth and the four seasons of the year1. Furthermore, these humors were used to describe the imbalances occurring within the body and mind as they would result in abnormal behaviors or emotions. For example, one common belief for extreme sadness was having too much black bile within the body1. To be fully emotionally well, there had to be a balance between all humors. In addition to the humoral theory, Hippocrates believed there was a connection between the body and mind and thought certain body parts played a role in mental illness1. This theory was accepted and used until the 19th century when more modern medicine and treatment proved otherwise1.

While mental disorders and abnormal behavior were treated with this method, there was a branching out of what this procedure was used for, and became increasingly more popular and accepted. Many acknowledged a more scientific approach to imbalances as opposed to evil spirits and spiritual abnormalities that were reflected in behaviors1. During this time, the procedure itself remained the same, but technology allowed for more advanced tools and equipment to be used as well as techniques in the operating room1. This allowed for a more precise procedure as well as better outcomes of the surgery. At this time, because there were so many advancements in the medical realm, many described the post-op look of the surgery on the patient as a work of art1.

He was a skilled artist and allowed his talent to show through his depictions of the body. At this time, there was no publishing that truly showed the magnitude of the body. His book allowed physicians and other individuals to understand more in-depth what the body looked like and how that could change procedures, including the craniotomy, moving forward. Insights into structures and more functions of the brain allowed even more advancements in the brain. This included shutting down previous ideologies made by previous individuals, including Galen1. There was more of a clear and precise direction in what procedures should look like and how to go about them. His anatomical contributions revolutionized modern medicine, including neurology.

At this time, some mental institutions were established and allowed patients who were considered mentally ill to be admitted and cared for. Only after a little bit of time did it come out that these patients were being treated terribly and unethically. Physical abuse, isolation, and many other conditions were put on these patients to cure what mental illnesses they were experiencing1. Prior to the opening of mental institutions, there was hesitance among the community as to whether or not these establishments were moral in the first place and the harsh treatment patients endured caused distress and frustration1. There soon emerged advocates for these types of institutions and eventually they all were shut down and patients were able to see what other treatments best fit them. Unfortunately, this left many patients on their own with nowhere to go1.

The rod did end up leaving his skull, but it left a hole both in his cheek and skull1. To everyone’s surprise, Gage did end up surviving and none of his cognitive skills were compromised; he was able to walk and talk normally. Afterward, he was able to recall details of the event and describe accurately the amount of time that had passed since the accident when he woke from a semi-coma1. Despite the fact that there were no physical changes after his injury, his behavior took a drastic change. Once described as a pleasant and hard-working man, he soon turned into a heavy drinker and was unable to hold a job for very long1. After studying the extent of the brain damage in the late 1900s, it was noted that his areas of decision-making and emotional processing were damaged, which was reflected in his behaviors1. It was this accident that proved life with excessive brain damage was possible, but that there was a connection between brain damage and behavior, mainly in the frontal cortex, which allowed more investigation in the future on how neural networks and structures contribute to behaviors.

After becoming a physician, he decided to focus on conditions relating to the nervous system and later on schizophrenia where he published multiple reviews on current research on psychiatry within the illness1. Throughout his career, he collected all information he could to create his own encyclopedia version of the nervous system. In his book, “The Physiological Diagnosis of Nervous System Diseases,” he defined more anatomically and physiologically the nervous system and gave a basis as to what the nervous system was1. After being the supervisor at a hospital, he decided to experiment on several schizophrenia patients where he performed topectomies, the removal of frontal cortex parts1. Only two of his patients died and unfortunately, his other patients experienced aphasia and seizures afterward1. Despite the controversy after presenting his results as well as the aftermath of the procedure, he was one of the first to perform psychosurgery and made way for what would become the lobotomy. His failures allowed for improvement in the field of psychosurgery in the future.

He was in the midst of his career when he received a letter from his mom on the state of his sister: her seizures and headaches were increasing as they had for the past decade at this point2. He then decided to operate on her in late 1928 where he discovered a very solid tumor at the bottom of her skull2. What was believed to be the end of a successful procedure, Penfield found himself staring at a piece of the tumor that attached itself at the bottom of her skull, making it impossible to remove the entirety of her tumor2. Despite buying her some time to spend with her husband and kids, he was unable to relieve her entirely of her tumor. After only several months, her seizures and headaches resumed1. Because of his guilt for not recognizing his sister's symptoms earlier, he dedicated himself to neurology research. He opened his own institution and while trying to find the origin of seizures, he ended up creating a precise map of sensory and motor functions in the brain, allowing future physicians and researchers to know more specifics about the brain that could guide them in their future advancements of localization1. This enabled them to more precisely investigate what brain regions could be connected to psychoses and where those connections lay in the brain.

Through his work and research, he hypothesized that the mentally ill suffered from abnormal neural networks within the brain that reflected in behaviors and thoughts1. He also worked on the frontal lobe as previous work established there was a connection between behavior and the frontal cortex. His decision to perform his first psychosurgery in 1935 would later become an incredible landmark in the field of psychosurgery. His 63-year-old patient, who suffered from depression, anxiety, hallucinations, and more, underwent a cutting of the white fibers in her frontal lobe and after two months, her psychiatrist noted her anxiety and depression decided rapidly1. This was one of the first successful leucotomies and was possible through trial and error as well as extensive work done by previous physicians. His more defined technique allowed the reduction of mental illness symptoms but kept cognitive functions intact.

These results were also more thoroughly discussed at the 1935 Neurological Congress where Walter Freeman, a neurologist in the U.S., took Moniz’s accomplishments and worked on his own advancements in the procedure1. In 1936, he and James Watt performed the first lobotomy in the U.S.1. Using a similar method, Freeman drilled two holes in the skull but excised more white matter than Moniz1. He later advanced his own procedure to be more transorbital, being described as an ice pick method for its precise access1. He did so well advancing his own procedure that his method was described as so simple and easy to the point surgeons could learn the technique within half a day of training1. If it weren't for the start of Moniz’s procedure and the sharing of his results, the advancements made around the world could not have been possible. It is when physicians and those in the medical field come together that they are able to advance the field for everyone’s benefit and good. This domino effect all started with Antonio Egas Moniz.

After some training, he went back to Portugal in 1911 as the head of neurology at the University of Lisbon1. At first, his research consisted of precisely mapping tumors in the brain with radiographic material but soon saw his attempt fail with the death of one of his patients1. He later had more success with being the first to map out peripheral structures using this kind of material in the human brain1. As he continued on, his curiosity about blood vessels being more visible by using opaque materials to radiographic substances lead him to be the first to discover arteriography in the brain1. This lead him to further investigate the white matter in the frontal cortex after observing many psychoses in patients. When he used previous methods, such as using radiographic material, losing several of his patients showed his ways of treatment to be inconsistent, but still used that thinking and decided there was only one option left: the leucotomy. This technique would later win him a Nobel Prize for establishing a connection between neural networks and psychosis.

Research has evolved in finding more ways neural networks and their abnormalities contribute to abnormal behavior and psychoses. One of these methods is electroconvulsive therapy. Instead of being cut open, this is a noninvasive way for patients who suffer severely from mental illnesses, including depression. While this is an underused treatment, it is a way for patients to have their whole brain electrically stimulated to create a small and well-controlled seizure that alters brain chemistry to improve symptoms1. TMS, or transcranial magnetic stimulation, is another stimulant method used in the brain that uses magnetic fields to stimulate nerve cells in areas that control mood1 . This also stimulates this area of the brain to improve mental illness symptoms. Without the establishment of neural connections in the brain related to psychosis, these more used and invasive treatments would not be in place today. These modern treatments allow for quicker recovery and more frequency in treatment administration and would not have been possible without the first step in psychosurgery.
