Nightmares linked to suicide
Even if nightmares aren’t real, the can cause serious damage. A new study is the first to report that the relationship between nightmares and suicidal behaviors.
Results show that suicidal thoughts, plans or attempts were present in 62 percent of participants who experienced nightmares and only 20 percent of those without nightmares. Multiple analyses suggest that nightmares may act as a stressor in people with post-traumatic stress disorder (PTSD). The nightmares may trigger specific types of negative cognitive thoughts — such as defeat, entrapment and hopelessness — which reinforce suicidal thoughts and behaviors. The pathways between nightmares and suicidal behaviors appear to operate independent of comorbid insomnia and depression.
“PTSD increases the risk of suicidal thoughts and behavior, and our study shows that nightmares, a hallmark symptom of PTSD, may be an important treatment target to reduce suicide risk,” said principal investigator Donna L. Littlewood, PhD researcher in medical and human sciences at The University of Manchester. “This study emphasizes the importance of specifically assessing and targeting nightmares within those individuals experiencing PTSD. In addition, monitoring and targeting levels of negative cognitive appraisals such as defeat, entrapment, and hopelessness, may reduce suicidal thoughts and behaviors.”
Study results are published in the March 15, 2016 issue of the Journal of Clinical Sleep Medicine.
Data for this study was collected from 91 participants who had experienced traumatic events, 51 of whom met criteria for PTSD currently, and an additional 24 of whom reported a prior diagnosis of PTSD. Nightmares were measured by summing the frequency and intensity ratings of relevant items on the clinician-administered PTSD scale. Participants also completed questionnaire measures of suicidal behavior, hopelessness, defeat, and entrapment. Given the interactions between insomnia, PTSD, and suicide, a measure of insomnia was included as a covariate. Analysis was also conducted with and without those participants who had comorbid depression.
