Jason A Hannah Professor of the History of Medicine, Professor of Psychiatry, University of Toronto

I have worked In the history of psychiatry for many years. I have also made contributions to the clinical discipline, in the form of proposing changes in the system of diagnosis. My recent book, co-authored with Dr Max Fink, The Madness of Fear: A History of Catatonia (Oxford UP) is an excellent example of this. Some of my books have achieved wide readership, such as my History of Psychiatry (Wiley), which has been translated into a number of languages. My interest in the Havana Syndrome arises from my research into differentiating psychogenic from somatogenic complaints. I have written extensively about the psychogenic variety (From Paralysis to Fatigue [Free Press]), but I think that the diplomats caught up in the Havana Syndrome has a real organic (somatogenic) complaint.
I have been a professor at the University of Toronto since 1967, first in the Department of History and, since 1991, in the Faculty of Medicine.
