After the First World War

Following the war, treatment options for affected veterans improved. Particularly in Britain, long-term asylum care became widely available, due in part to a better understanding of the condition. Additionally, military officials were later embarrassed because during the war some shell shocked soldiers, of many nationalities, had been executed for what had then been considered cowardice.

Veterans in Southwestern Ontario could receive treatment at the Ontario Hospital, London, or at Westminster Hospital, London. Established in 1918, Westminster began as a military hospital. After the First World War, it was used as a hospital for mentally ill veterans.

The inter-war years saw developments in civilian psychiatry that would benefit military psychiatry during the Second World War. Especially among the Allied nations, there came to be a greater deal of compassion and humanization in available treatments. Soldiers in the Second World War tended to receive care that included rest and relaxation, or simple talk and drug therapies.
