Thesis title: Inventing the post-viral: the long-term consequences of viral illness in British medicine and psychiatry, c.1900-c.1975




Thesis abstract:

In 1918, a Professor of Medicine at the University of Sheffield named Arthur Hall was among the first in Britain to identify and describe an epidemic disease named Encephalitis Lethargica. Over the next three decades, this disease category would evolve in a multitude of ways, shifting from a primarily 'acute', 'physical' disease to one which was recognised to cause serious and chronic 'mental after-effects'.

Focusing on cases experiencing such changes in behaviour, this project uses Encephalitis Lethargica as a lens through which to contextualise the changing medical, psychiatric and psychological conceptions of antisocial behaviour in Britain from 1918 to 1959.

Building upon historical analyses which have hitherto explored this process through paying attention to the links between moral defect and psychopathy, this project offers an alternative chronology through focusing the emergence of behaviours associated with Encephalitis Lethargica which were antisocial but not necessarily illegal or criminal.

In the era of COVID-19, moreover, this project hopes to shed light on the ways in which epidemic diseases evolve in relation to particular medical, political and economic factors and concerns, and more importantly, the long-term implications of these relationships.
