A retrospective diagnosis of epilepsy in three historical figures: St Paul, Joan of Arc and Socrates

What caused Joan of Arc's neuropsychiatric symptoms? Medical hypotheses from 1882 to 2016

Between 1882 and 2016, the medical literature offered a variety of etiologic hypotheses to explain Joan of Arc's voices, visions, and unwavering belief that she was the instrument of God. Although Joan lived from 1412 to 1431, there is extensive primary documentation of her life, including transcripts of her testimony during the Trial of Condemnation. Once this source material was compiled and made available, physician-authors began to theorize about Joan's neuropsychiatric symptoms in the context of her remarkable achievements. This article summarizes all papers written by physician-authors about Joan of Arc. The historical flow of diagnostic speculation in the medical literature reflects the cultural context in which it was produced as well as the emergence of novel ideas and new technologies in psychiatry, neurology, and neuropsychiatry. The early literature offered psychological theories and addressed the question of whether Joan was sane. The later literature focused on the possibility that Joan might have had epilepsy, with discussions of seizure etiology and possible cerebral focus, and also reflections on the purview of science as well as spirituality and the brain. This article offers the first comprehensive review of the medical literature about Joan of Arc, making this scholarship more accessible.

Joan of Arc: Sanctity, witchcraft or epilepsy?

OBJECTIVE

The objective of this article is to describe whether Joan of Arc had epilepsy and how that may have influenced her sense of mission and ability to encourage thousands of people to help her to chase the English out of France.

METHODS

Documentation of her Trial of Condemnation in 1431 provides a description of her episodes of experienced voices and visions.

RESULTS

From the age of thirteen, Joan of Arc experienced frequent episodes of auditory hallucinations associated with elementary or complex visual hallucinations (e.g., a great light or human faces). These had sudden onset, lasting seconds or minutes at most, and occurred when awake or during sleep, arousing her. Some could be triggered by an auditory stimulus. She had no disorganized thought between the episodes.

CONCLUSIONS

The semiology of the episodes is very suggestive of epileptic seizures, which have been considered as ecstatic by some authors or as partial epilepsy with auditory features by others, which seems more concordant with the ictal symptoms. The auditory and visual hallucinations could have had a religious content because during her childhood and adolescence, she was brought up in a religious environment, insomuch as this content first undefined only appeared after a few seizures. We can suppose that such hallucinations, without the knowledge of their medical origin, gave her a sense of divine mission, hence, a real strength to try to accomplish the orders she heard during the episodes. Her role during the Hundred Years' War and her narration of her strange episodes led her to be burned for heresy at the age of nineteen, yet rehabilitated 25 years later and to be canonized for her achievements in 1920.

His majesty's psychosis: the case of emperor Joshua Norton

Case studies are a cornerstone of medical education and have been shown to be effective teaching tools. When teaching is entertaining, learning is enhanced and, therefore, strange and unusual cases present the opportunity to illustrate issues of disorder and illness in an engaging manner. The author illustrates this concept by presenting the life and character of Joshua Norton, who declared himself Emperor of the USA in 1859 and "reigned" until his death in 1880. Although grandiose claims are not rare among patients, Norton is unlike most self-proclaimed royalty in that his community embraced him and joined in with his fantasy. No psychiatrist or psychologist has ever opined on the matter of whether or not Norton's claims stemmed from mental disorder, and the author therefore presents Emperor Norton as a unique case in psychiatric history to explore first what diagnosis best explains his story and, second, whether he merits a diagnosis at all.
