title: Complicated grief in those bereaved by violent death: the effects of post-traumatic stress disorder on complicated grief.
abstract: Violent death, such as homicide, accident, and suicide, is sudden, unexpected, and caused by intentional power, The prevalence of complicated grief among those bereaved by violent death is 12.5% to 78.0%. The factors affecting this prevalence rate are considered to be comorbid mental disorders, lack of readiness for the death, difficulty in making sense of the death, high level of negative appraisal about the self and others, and various social stressors. Post-traumatic stress disorder is, in particular, considered to contribute to the development of complicated grief by suppressing function of the medial prefrontal cortex and the anterior cingulate cortex, which works at facilitating the normal mourning process. An understanding of the mechanism and biological basis of complicated grief by violent death will be helpful in developing effective preventive intervention and treatment.
