Career
Yealland qualified from the University of Western Ontario in 1912. Yealland came to Britain during World War I and worked in London at the National Hospital for the paralyzed and epileptic, there he mainly dealt with cases of hysteria. Yealland did not consider shell shock an illness, and believed men showing such symptoms displayed a lack of discipline or sense of duty.
He practiced a form of therapy based on punishment.
He was an exponent of auto-suggestion. Most of his patients recovered through suggestion and persuasion however in a few cases of severe symptoms he performed therapy with electric shock treatment.
He gained a reputation for curing and sending his patients back to the trenches quickly. Yealland published his wartime findings in Hysterical Disorders of Warfare in 1918.
Allegedly, Yealland claimed a success rate of 100 per cent, and while his methods of treatment were regarded as particularly unethical by the academic discourse of the 1980s, more recent research suggests that his ill-reputation might have come about due to an over-representation of successful cases in Yealland"s own works.
Lewis Yealland appears in Pat Barker"s Regeneration, where he is portrayed unsympathetically, treating a shell-shocked man suffering from hysterical mutism using electric shock treatment and showing no compassion for his patient.
