Mass violence and mental health--recent epidemiological findings

There is growing awareness of the mental health impact of all types of mass violence. The exposure of large population groups, mostly having no mental health problems prior to the exposure, and the subsequent development, in a significant proportion of the population, of a variety of psychiatric symptoms and disorders represent both a challenge and an opportunity for psychiatrists. There is sufficient evidence from the variety of mass violence/conflict situations, that a significant proportion of the exposed population develop different mental disorders. There are vulnerable groups like women, children, widows, orphans, elderly, disabled, those exposed to severe pain and loss of body parts. There is also a consistent finding of the dose-response to the amount of trauma and the prevalence of mental disorders. There is growing recognition that there is need to consider a variety of syndromes, in addition to post-traumatic stress disorder (PTSD) like acute stress disorder (ASD), depression, complicated bereavement reactions, substance use disorders, poor physical health, fear, anxiety, physiological arousal, somatisation, anger control, functional disability and arrest or regression of childhood developmental progression. The challenge is to reach all of the ill persons and provide mental health services. The opportunity provided by this field is to develop a better understanding of issues of resilience, recovery and effectiveness of public health approaches to mental health care.
