The Glasgow Coma Scale: 50-year anniversary.

In 1974, Sir Graham Teasdale and Bryan Jennett wrote the "Assessment of coma and impaired consciousness, A practical scale," which has become one of the most influential papers in the history of traumatic brain injury, with more than 10,000 citations as of January 2024. Today, it is one of the most widely used tools in emergency departments, providing a reliable general overview of the patient's consciousness status.

King Charles VIII of France's Death: From an Unsubstantiated Traumatic Brain Injury to More Realistic Hypotheses.

On April 7, 1498, Charles VIII, King of France, attended a game of palm in the ditches of the Château d'Amboise. The 27-year-old King suddenly collapsed and became comatose. He laid down, almost on his own, on a straw mat that was hastily arranged, and he died 9 hours later. His contemporaries perceived his death as a perfect reminder of fatality: a king could die alone in a miserable gallery. All who looked into this curious death had dwelled on the frontal blow to head that the king had sustained right before his demise and had not considered alternative scenarios. The present study, still with limited available evidence, aimed to reexamine the historical account of his death in light of modern medical knowledge. It is virtually impossible that a minor bump with low kinetic energy could kill a 27-year-old man. Many historical accounts of Charles VIII's life and death, including Italian ambassadors' letters, led us to reconsider the commonly held version and to propose an alternative hypothesis. We have concluded that Charles VIII had experienced an acute consciousness disorder with language impairment that could have been related to an epileptic condition secondary to neurosyphilis. We have discussed whether a more accurate diagnosis for the cause of death could be obtained by a pathological analysis of the King's remains.

Legacies of Neurosurgery and its Implications on Global Neurosurgery Today.

Trephination, the practice of boring a hole in the skull, is one of the oldest surgical procedures performed by and on humans. Fossil records show evidence of trephined skulls on separate continents throughout ancient history. Even more remarkably, fossils show that ancient humans actually survived the procedure, some more than once. Ancient mythologies and texts provide context to the fossil record, indicating that trephination was performed some of the time for medical indications, including traumatic head injury and intractable neurologic conditions. In the modern day, traumatic brain injury accounts for a significant percentage of the overall global burden of disease and its incidence is disproportionately increasing in low- and middle-income countries. In critical situations, neurosurgical intervention may be indicated. The burr hole procedure, or trephination, was identified as an essential surgical procedure that all first-level hospitals should be able to perform; however, there exists a dramatic lack of access to neurosurgical specialists and care globally, especially among low- and middle-income countries. Task-shifting/sharing is one paradigm that may be used effectively to broaden access to this life-saving procedure but it is at the moment a contested practice.

Considerations about the Neuropsychiatric Conditions of Quixote of La Mancha. / Consideraciones sobre las condiciones neuropsiquiátricas del Quijote de la Mancha.

Don Quixote of La Mancha, the picturesque character created by Miguel de Cervantes Saavedra in his immortal book The Ingenious Nobleman Sir Quixote of La Mancha, presents several neuropsychiatric conditions, including tremor, sleep disturbances, neuropsychiatric symptoms, syncope, perception disorders and traumatic brain injury. Throughout the masterpiece, there are episodes where the aforementioned disorders are evident. This paper makes a list of them and analyses them in the light of the current knowledge of those conditions.

"The books and the night", neurological perspective on Jorge Luis Borges' blindness

The works of Argentinian scholar Jorge Luis Borges (1899-1986) have captivated physicians. An assiduous reader, he was given, with magnificent irony, "books and the night". Borges suffered from chronic and irreversible blindness, which influenced much of his work and has been the subject of different literary and diagnostic analyses from the ophthalmological point of view. However, the characteristics of his visual impairment have escaped the neurological approach, which is why we reviewed his work looking for data suggesting a concomitant brain injury. On his autobiography, he recounts how, during an episode of septicemia, he suffered hallucinations and loss of speech; in addition, in some poems and essays he describes data that suggest "phantom chromatopsia", a lesion of cortical origin. After that accident, Borges survived with a radical change in literary style. Although a precise diagnosis is impossible, his literary work allows recognizing some elements in favor of concomitant brain involvement.

A different aspect of the unexpected death of Mozart at the age of 35 years.

The cause of the early death of Wolfgang Amadeus Mozart (1756-1791) at the age of 35 has been the source of much discussion in the medical community. Investigators attributed to Mozart nearly 150 different medical diagnoses. However, the neurosurgical aspect of the early death of Mozart has yet to be well-analyzed, and this subject was investigated herein. The key words "Mozart" and "Mozart's death" were searched in PubMed as well as the libraries of universities. The main source was the archive and website of Internationale Stiftung MOZARTEUM/Salzburg (www.mozarteum.at) and the cranium stored in the Internationale Stiftung Mozarteum in Salzburg/Austria. The linear fracture of the cranium is important, since it shows the neurosurgical aspect of the early death of Mozart. Mozart's disease was most likely a neurotraumatologic one. His fracture likely occurred several months before his death, as evidenced by signs of healing. Intense headaches and declining musical performance in his last year may have been influenced by intracranial hemorrhage induced by the linear fracture. His final disease therefore may have been chronic postconcussion syndrome depending on chronic calcified epidural hematoma.

Henrique Dumont: how a traumatic brain injury contributed to the development of the airplane.

The life and death of Henrique Dumont (1832-1892) is little known, being usually remembered as Alberto Santos-Dumont's father. This report describes the history of this Brazilian engineer, also known as the King of Coffee, who achieved enormous business success and fortune in the late nineteenth century. In 1890, during the inspection of his farm, the world's largest coffee plantation at that time, he fell from a carriage, which left him a hemiplegic. This forced him to sell the farm and move to France for treatment. Before his death two years later, he gave his 18-year-old son bits of advice, and distributed his inheritance, which allowed Alberto to study in Paris and finance his experiments that would culminate in the development of the airplane. The diagnostic and therapeutic possibilities are also discussed.

RESUMO A vida e especialmente a morte do brasileiro Henrique Dumont (1832-1892) são pouco conhecidas, sendo geralmente lembrado como pai de Alberto Santos Dumont. Relatamos a história deste engenheiro que obteve enorme sucesso empresarial no final do século XIX, sendo denominado Rei do Café. Em 1890, durante a inspeção da sua fazenda, maior cafeicultura do mundo na época, caiu da charrete e ficou hemiplégico. Isso o fez vender a fazenda e buscar tratamento na França, trazendo o primeiro automóvel do Brasil ao retornar. Antes de morrer dois anos após o acidente, deu valorosos conselhos e distribuiu sua herança ao filho Alberto, então com dezoito anos de idade, que pôde assim estudar em Paris e financiar seus experimentos que culminariam no desenvolvimento do avião. São discutidas e contemporizadas as possibilidades diagnósticas e terapêuticas relacionadas ao déficit neurológico.

One hundred years (and counting) of blast-associated traumatic brain injury.

Blast-associated traumatic brain injury (TBI) has become one of the signature issues of modern warfare and is increasingly a concern in the civilian population due to a rise in terrorist attacks. Despite being a recognised feature of combat since the introduction of high explosives in conventional warfare over a century ago, only recently has there been interest in understanding the biology and pathology of blast TBI and the potential long-term consequences. Progress made has been slow and there remain remarkably few robust human neuropathology studies in this field. This article provides a broad overview of the history of blast TBI and reviews the pathology described in the limitedscientific studies found in the literature.

Similar cranial trauma prevalence among Neanderthals and Upper Palaeolithic modern humans.

Neanderthals are commonly depicted as leading dangerous lives and permanently struggling for survival. This view largely relies on the high incidences of trauma that have been reported1,2 and have variously been attributed to violent social behaviour3,4, highly mobile hunter-gatherer lifestyles2 or attacks by carnivores5. The described Neanderthal pattern of predominantly cranial injuries is further thought to reflect violent encounters with large prey mammals, resulting from the use of close-range hunting weapons1. These interpretations directly shape our understanding of Neanderthal lifestyles, health and hunting abilities, yet mainly rest on descriptive, case-based evidence. Quantitative, population-level studies of traumatic injuries are rare. Here we reassess the hypothesis of higher cranial trauma prevalence among Neanderthals using a population-level approach-accounting for preservation bias and other contextual data-and an exhaustive fossil database. We show that Neanderthals and early Upper Palaeolithic anatomically modern humans exhibit similar overall incidences of cranial trauma, which are higher for males in both taxa, consistent with patterns shown by later populations of modern humans. Beyond these similarities, we observed species-specific, age-related variation in trauma prevalence, suggesting that there were differences in the timing of injuries during life or that there was a differential mortality risk of trauma survivors in the two groups. Finally, our results highlight the importance of preservation bias in studies of trauma prevalence.

The Neuropsychology of Traumatic Brain Injury: Looking Back, Peering Ahead.

The past 50 years have been a period of exciting progress in neuropsychological research on traumatic brain injury (TBI). Neuropsychologists and neuropsychological testing have played a critical role in these advances. This study looks back at three major scientific advances in research on TBI that have been critical in pushing the field forward over the past several decades: The advent of modern neuroimaging; the recognition of the importance of non-injury factors in determining recovery from TBI; and the growth of cognitive rehabilitation. Thanks to these advances, we now have a better understanding of the pathophysiology of TBI and how recovery from the injury is also shaped by pre-injury, comorbid, and contextual factors, and we also have increasing evidence that active interventions, including cognitive rehabilitation, can help to promote better outcomes. The study also peers ahead to discern two important directions that seem destined to influence research on TBI over the next 50 years: the development of large, multi-site observational studies and randomized controlled trials, bolstered by international research consortia and the adoption of common data elements; and attempts to translate research into health care and health policy by the application of rigorous methods drawn from implementation science. Future research shaped by these trends should provide critical evidence regarding the outcomes of TBI and its treatment, and should help to disseminate and implement the knowledge gained from research to the betterment of the quality of life of persons with TBI.

Henry II of France (1519-1559) and His Death From Meningoencephalitis Following Cranial Trauma.

This historical review summarizes the most significant theories regarding the cause of death of King Henry II of France (1519-1559) and the circumstances under which it occurred. Although the historical testimonies are inconclusive and vague, postmortem analysis has shown that the King died of meningoencephalitis, caused by hematoma of a cerebral contusion, with effusion in the cerebral laminae and its surrounding tissue initiated by a periorbital fracture.

A Cranial Trauma was the Cause of Death of Charles VIII of France (1470-1498).

This article summarizes the reign, life and death, of Charles VIII of France. Also we intend to investigate current views on his cause of death, contradictions and opinions of his biographers. Poisoning, disease, and injury are the possible causes of his death but, according to the literature, cranial trauma was the most probable cause of death of the King Charles VIII of France.

The face of war: Trauma analysis of a mass grave from the Battle of Lützen (1632).

Contemporary accounts of battles are often incomplete or even erroneous because they reflect the-often biased-viewpoints of the authors. Battlefield archaeology faces the task of compiling an historical analysis of a battle and of gathering all the available facts. Besides cultural historical evidence and artefacts, the human remains of those who have fallen in battle also provide invaluable information. In studying mass graves from a military context, the injury types and patterns are significant. They allow us to reconstruct the circumstances surrounding the soldiers' deaths and provide information on the hostilities that occurred on the battlefield. One such mass grave was discovered in 2011 at Lützen, Saxony-Anhalt (Germany). Based on its geographical location and on the results obtained from archaeological examinations carried out in the area, the grave could be dated to the Thirty Years War (1618-1648). Further archaeological research confirmed that the dead had been soldiers from the Battle of Lützen (1632). The mass grave was block-lifted and then comprehensively examined at the State Museum of Prehistory in Halle (Saale). As well as osteological examinations to determine age, sex, height, state of health, i.e. diseases or injuries, imaging methods were also employed and histological and isotopic analyses carried out. The focus of this study was on the injuries sustained by the soldiers both prior to and during the battle. The results revealed that the 47 deceased had been between the ages of 15 and 50 when they died. Numerous healed injuries showed that the men had often been involved in violent encounters. Approximately three in every four soldiers had injuries that could have been fatal. Wounds inflicted by handguns, particularly to the skull, were predominant. The integrative analysis of the archaeological and anthropological data allowed us to conclude that the majority had been killed during a cavalry attack.

Chen Jingrun, China's famous mathematician: devastated by brain injuries on the doorstep to solving a fundamental mathematical puzzle.

Chen Jingrun (1933-1996), perhaps the most prodigious mathematician of his time, focused on the field of analytical number theory. His work on Waring's problem, Legendre's conjecture, and Goldbach's conjecture led to progress in analytical number theory in the form of "Chen's Theorem," which he published in 1966 and 1973. His early life was ravaged by the Second Sino-Japanese War and the Chinese Cultural Revolution. On the verge of solving Goldbach's conjecture in 1984, Chen was struck by a bicyclist while also bicycling and suffered severe brain trauma. During his hospitalization, he was also found to have Parkinson's disease. Chen suffered another serious brain concussion after a fall only a few months after recovering from the bicycle crash. With significant deficits, he remained hospitalized for several years without making progress while receiving modern Western medical therapies. In 1988 traditional Chinese medicine experts were called in to assist with his treatment. After a year of acupuncture and oxygen therapy, Chen could control his basic bowel and bladder functions, he could walk slowly, and his swallowing and speech improved. When Chen was unable to produce complex work or finish his final work on Goldbach's conjecture, his mathematical pursuits were taken up vigorously by his dedicated students. He was able to publish Youth Math, a mathematics book that became an inspiration in Chinese education. Although he died in 1996 at the age of 63 after surviving brutal political repression, being deprived of neurological function at the very peak of his genius, and having to be supported by his wife, Chen ironically became a symbol of dedication, perseverance, and motivation to his students and associates, to Chinese youth, to a nation, and to mathematicians and scientists worldwide.
