Psychological injuries may occur as the result of severe stress, trauma, or serious physical injury to oneself or others. They can be a consequence of actual, threatened, or witnessed events. For injuries to be considered psychological in nature, they must involve damage or dysfunction to a person’s thinking, feeling and behaviour that impair both daily functioning and sense of emotional well-being. Common psychological injuries include traumatic stress and PTSD, depression, and other anxiety disorders. Persistent chronic pain and traumatic brain injuries resulting from accidents and other events may also be considered psychological injuries.
