Posttraumatic stress disorder at the end of life: Extant research and proposed psychosocial treatment approach

According to some estimates, 84% of people experience a traumatic event during their lives (Vrana & Lauterbach, 1994), and 15% to 24% then develop posttraumatic stress disorder (PTSD). Many carry with them lasting effects of trauma as they age and enter the last phase of life. PTSD manifests in unique ways at the end of life, possibly disrupting factors associated with a positive dying process, including social support, medical communication, life review, and acceptance of death. Terminally ill people with PTSD may suffer more emotional distress, lower quality of life, and poorer medical prognosis than those without PTSD. Unfortunately, healthcare providers may not be trained to address this issue. This article reviews the literature concerning how PTSD may affect the end of life and proposes an intervention model based on a palliative care philosophy.
