The relationship between future self-continuity and suicide risk in military veterans with traumatic brain injury

Veterans with Traumatic Brain Injury (TBI) have an increased risk for suicide. A lack of Future-Self Continuity (FSC), which refers to the sense of “psychological connectedness” that a person has between their present and future selves, has also been associated with suicide risk. For this study, 308 U.S. military veterans, 39 of whom self-reported a […]

Exploration of race and ethnicity, sex, sport-related concussion, depression history, and suicide attempts in US youth

Importance  Racial, ethnic, and sex disparities for concussion incidence and suicide attempts in youth have been reported, but data on the interaction of these variables in a large national data set are lacking. Understanding how race and ethnicity interact with sex and concussion to influence suicide attempts could yield critical information on the sociocultural impact of […]

Association between concussions and suicidality in high school students in the United States

Objective: To examine whether sustaining a concussion remained a significant predictor of suicidality after controlling for relevant covariates (e.g., sexual abuse/assault, bullying, substance use, depression), hypothesizing that the relationship between concussion and suicidality would become non-significant after controlling for these variables. Design: This study involved secondary data analysis of the 2019 Youth Risk Behavior Surveillance (YRBS) System, […]

Role of inflammation in suicide: From mechanisms to treatment

Suicidal behavior is complex and manifests because of a confluence of diverse factors. One such factor involves dysregulation of the immune system, which has been linked to the pathophysiology of suicidal behavior. This review will provide a brief description of suicidality and discuss the contribution of upstream and downstream factors in the etiology of suicidal […]

The role of inflammation in suicidal behaviour

Objective Over the past decade, clinical data have accumulated showing that inflammation might contribute to the pathophysiology of suicide. To evaluate the associations and to identify the support for pathways linking inflammatory processes with suicidal behaviour, a comprehensive review of the literature was undertaken. Method The search terms ‘cytokine’, ‘risk factors’, ‘kynurenine’, ‘asthma’, ‘allergy’, ‘autoimmunity’, […]

Suicide attempts in US veterans with chronic headache disorders: A 10-year retrospective cohort study

Objectives: A large-scale retrospective analysis of veterans with chronic pain was conducted to examine (1) the annual incidence of suicide attempts (SA) in veterans with chronic headache and other chronic pain conditions, and (2) the risk of SA in men and women with chronic headache and chronic headache concurrent with traumatic brain injury (TBI) as compared […]

Reported history of traumatic brain injury among suicide decedents: National Violent Death Reporting System, 2003-2017

Introduction Traumatic brain injury is a major cause of death and disability in the U.S., and research shows that individuals who suffer traumatic brain injury have an increased risk for suicide. This study examines the characteristics of suicide decedents with a documented traumatic brain injury history using a database containing circumstantial data on suicides and […]

Prevalence and severity of psychiatric disorders and suicidal behavior in service members and veterans with and without traumatic brain injury: Systematic review

Objectives: Assess prevalence and severity of posttraumatic stress disorder, suicidal behavior, and depressive, substance use, and anxiety disorders in US service members or Veterans with and without a deployment-related mild traumatic brain injury (TBI) (mTBI). Design: Systematic review using multiple databases (January 2000 to October 2017). We included national or geographically diverse samples. Main Measure: Prevalence and […]

The relationship between suicidal responses and traumatic brain injury and severe insomnia in active duty, veteran, and civilian populations

This study examined how a positive traumatic brain injury (TBI) screening and insomnia severity relate to suicidal outcomes across active duty, veteran, and civilian samples. Data were used from 3,993 participants from 19 studies. We conducted a series of analyses by group to identify which significantly differed on the variables of interest. TBI and insomnia […]

Traumatic brain injury and suicide

There is a need for more resources that are specifically targeted toward TBI survivors who may be considering suicide. Based upon this need, researchers at the VA VISN 19 Mental Illness Research, Education, and Clinical Center (MIRECC) produced this information and resources guide. The target audience is clinicians and care providers working with TBI survivors. […]
