PTSD is an anxiety disorder caused by very stressful, frightening or distressing events, which are often relived through flashbacks and nightmares. The condition, formerly known as “shellshock”, first came to prominence when men returned from the trenches of World War One having witnessed unimaginable horrors. More than 100 years after the guns of that conflict fell silent, PTSD is still predominantly associated with war and as something largely experienced by men.
