Reconstructing a doctrine: Galen on apoplexy

Historic review: select chapters of a history of stroke

BACKGROUND

There is no shortage of books, chapters and papers on the history of stroke focusing predominantly on the last 150 years and enumerating endless "milestones". Instead of adding another article to this body of knowledge, this essay aims at ensuring awareness for the "big picture", the "grandes routes", and the "striking breakes" without overloading the reader with too much detail.

RESULTS

From a medical point of view, the history of stroke consists of two periods: the early era from the beginnings to 1812, and the following period from 1812 up to the present. It is argued that both periods require different methodical approaches, including disparate historiographical perspectives and varying forms of interpretation. In order to fully understand medical writings of the Greco-Roman era (Hippocratic writings, Galenic corpus) on "apoplexy", a solid knowledge of ancient doctrines concerning health and disease is indispensable. During the Middle Ages, the spiritual perspective can be highlighted by focusing on miracle healing and patron saints. While stroke basically remained a conundrum for many doctors and patients in early modern times (ca. 1500-1800; Platter, Wepfer), the revolutionary perception and definition of the disease as a result of a lesion in the 1810s (Rochoux, Rostan) opened the door to a productive relationship of the upcoming discipline "neurology" with the natural sciences during the nineteenth century and beyond (Virchow et al.). The mostly unwritten history of stroke in the twentieth century should not only include the medical, but also the patient's and the societal perspective.

CONCLUSION

A deeper insight into the recent and distant past will produce better educated strokologists - physicians who are able to put their own work into perspective.

Galen's place in Avicenna's The Canon of Medicine: Respect, confirmation and criticism

Galen (129-199 A.D.), an ancient Greek scholar, is one of the most influential and recognized physicians and surgeons in the history of medicine. He is one of the most influential Greek scholar in Persian medicine, who has been repeatedly cited by Iranian scholars. The purpose of this article is to describe the exact position of Galen in Avicenna's The Canon of Medicine, the most important work of Persian medicine. In The Canon of Medicine, Galen is cited about 300 times, and Avicenna always admired and praised Galen repeatedly. Galen's ideas were important to Avicenna, but there are also many elements of Galen's views that Avicenna challenged or criticized. For example, Avicenna diverged from Galen's philosophical view in medicine and rejected some of Galen's pharmaceutical opinions and Galen's views on the physiology of pain, the physiology of pulse, the same nature of the tendons and nerves and separation of the mind and body. Although the views of Greek scholars, especially Galen, in The Canon of Medicine have been quoted abundantly, Avicenna revised the knowledge of the ancient scholars through critical thinking and relying on observation and testing, systematized the science of medicine and introduced many ideas and innovations. As such, Europeans considered Avicenna as the most prominent physician of the Islamic Golden Age.

Understanding the cultural meanings of stroke in the Ghanaian setting: A qualitative study exploring the perspectives of local community residents

Background: Stroke has undergone different medical constructions over the years. While the medical profession posits that disease is a biological condition, universal and unchanging, social constructionists perceive illness as the social meaning of the biological condition. Even though the medical notion of stroke is monolithic and sometimes contradicts the representations by local community residents, little attention has been paid to understanding the cultural meanings of stroke. This study explores the cultural meanings of stroke in five different cultural settings across Ghana. Methods: 30 focus group discussions (FGDs) were conducted with local community members in five communities (Ga Mashie, Tafo, Gyegyeano, Chanshegu and Agorve) located in five regions in Ghana. The FGDs were conducted in Ga, Twi, Fante, Ewe and Dagbani, and were transcribed verbatim into English. The transcripts were analysed thematically. Results: The local words used for stroke in all the five cultural settings focused on physical disability associated with stroke after its onset, and this formed the dominant source of fear about the condition. Participants mentioned that spiritual and left-side stroke have the most debilitating impact on the sufferer. Although there was a general consensus that anyone can be at risk of stroke, there was a gender dynamics in the explanation of risk relativity. Participants believed that stroke can be cured through early detection and treatment, use of herbal medicines, and availability of financial resources. Compared to other disabling conditions, the community residents perceived stroke to be more severe due to the multifaceted disabilities associated with the condition. Conclusions: This study showed that the social meanings of stroke in the five communities are multifaceted, and reflected co-existence of biomedical and cultural frameworks.  The findings showed the need to pay good attention to the sociocultural context when developing interventions strategies on stroke prevention and control in Ghana.

Chapter 27: a history of cerebrovascular disease

Stroke is central to the history of cerebrovascular disease. References to this condition already appear in the Hippocratic corpus, referred to as apoplexy, which was defined by the clinical presentation: a sudden collapse, a loss of consciousness, a lack of movement, and included a variety of pathologies. A humoral imbalance was seen as the causation. In the 17th century, Johannes Wepfer, a Swiss physician, first demonstrated that apoplexy was caused by an intracranial hemorrhage; Thomas Willis, an English anatomist, explored the role of the cerebral arteries. Stroke became a cerebrovascular disease. By the 19th century, based on extensive clinico-pathological correlates initiated at the Paris Medical School, a vascular basis was firmly established and a range of pathologies determined. Apoplexy was considered too imprecise, and the term abandoned in favor of the term "cerebro-vascular accident" and latterly stroke. Although physicians of the 19th century utilized a wide variety of therapies in the treatment of stroke, with particular emphasis on blood letting, therapeutic nihilism dominated stroke management well into the 20th century. Following the mid 20th century work by C. Miller Fisher, with the recognition of the importance and the therapeutic implication of the carotid artery in stroke, the specialty of stroke medicine came into being. Therapeutic nihilism was replaced by an increasing armamentarium of therapeutic interventions.

A diary of epilepsy in the early 1800s

This article describes the diary of a man from 19th-century England (1829-1834) that documents the onset and course of his wife's epilepsy after a stroke. Her stroke produced aphasia and right hemiparesis, but her epilepsy was the diary's focus and caused the greatest concern. The diary documents the history of her epilepsy in detail. In addition to tonic-clonic seizures, she experienced frequent bouts of status epilepticus and complex partial seizures. The diary contains some of the earliest recorded descriptions of status epilepticus and its aftermath of delirium, mood disorder, and hysteria. It also offers some of the earliest and most detailed accounts of complex partial seizures. Bleeding by cupping was the only symptomatic or prophylactic treatment recorded. These aspects of the diary are presented, as are the historical perspectives on epilepsy, including early beliefs and stigmas, therapeutic remedies, and early European views of epilepsy.

Seventeenth century concepts of "apoplexy" as reflected in Bonet's "Sepulchretum"

The term "apoplexy," which has been in use since antiquity, referred to a catastrophic illness with an abrupt loss of consciousness and a frequently fatal outcome. During the sixteenth and seventeenth centuries scholastic approaches that relied on authorities were merging with an observational approach to medicine and Galen's speculation that apoplexy was due to an accumulation of phlegm or black bile in the cerebral ventricles began to be seriously challenged. The most extensive collection of case reports with autopsies published in the seventeenth century was Theophile Bonet's Sepulchretum sive Anatomia Practica. Section 2 of Book I of the Sepulchretum contains 70 case reports of patients that died with the diagnosis of apoplexy. The scholia in this section provide an idea for the modern reader of the notions physicians had of apoplexy in the seventeenth century. The Sepulchretum was an important book for physicians of the late seventeenth and eighteenth centuries. It played an important role in the development of modern medicine and it was an important foundation for Morgagni's De Sedibus et Causis Morborum. This essay reviews the pathological findings reported in victims of apoplexy and examines the views concerning the symptomatology, pathogenesis, etiology, and treatment of this condition that were prevalent at that time.

Roman emperors suffering from apoplexy: the medical and historical significance of classical literary sources

According to various Greek and Latin texts, several Roman emperors died of "apoplexy". This paper presents a systematic collection and evaluation of these sources. The contents of the texts are compared with contemporary knowledge as well as present-day perspectives. In retrospect, few of the "royal cases" can be classified as cerebrovascular disorders.

Galen and the ventricular system

This paper examines the anatomy and physiology, together with the pathophysiology, of the ventricular system of the brain, as it was understood by arguably its greatest exponent in Western Antiquity, Galen. According to him, the purpose of the ventricles was to elaborate, store and distribute psychic pneuma, the motive force of Galenic neurology, throughout the nervous system. However, impressive as the delineation of the ventricular system is, the details of this distribution are not forthcoming from Galen. Finally, I discuss the ventricles as the site of intellect, a notion only tentatively advanced by Galen, but cast into dogma by his successors. For all the mistakes Galen made in anatomy and physiology, the study of the ventricular system reveals a mind not dissimilar to our own.

What did the Greeks mean?

By tracing in the work of medical authorities, some of whom are not widely quoted, the changing meaning of three neurological terms used in ancient Greece - poplexia, epilepsia and cephalalgia - the development of Greek ideas about neurological science may be appreciated. It may be concluded that the achievement of the schools of Greek medicine was in keeping with the level attained by the ancient Greeks in philosophy and other aspects of civilization.
