In this episode, our panel look at traumatic events and how the effects may not just be localised to where the attacks take place. They look at some interesting evidence in the context of 9/11 which suggests that the psychological effects can travel thousands of miles.

This is part two of the first in our series of podcasts with the British Journal of Psychiatry. It discusses a recent research paper entitled "Increased incidence rate of trauma- and stressor-related disorders in Denmark after the September 11, 2001, terrorist attacks in the United States", which was published in the American Journal of Epidemiology and highlighted in the Kaleidoscope section of the British Journal of Psychiatry. The panel for this discussion featured:

- Josefien Breedvelt, Research Manager at the Mental Health Foundation

- Derek Tracy, Consultant Psychiatrist at Oxleas NHS Foundation Trust

- Chris White, who works for the Mental Health Foundation and has his own experience of mental health problems

- Mark Brown, mental health campaigner well-known as @MarkOneInFour on Twitter and also with his own lived experience of mental ill health.
