Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

114
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Summary
This summary is machine-generated.

Younger Veterans and Service Members with traumatic brain injury (TBI) and a history of mental health issues face higher risks for suicide attempts (SA) and suicidal ideation (SI) post-injury. Regular screening for suicidality is crucial.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Public Health

Background:

  • Traumatic brain injury (TBI) is a significant concern among Veterans and Service Members (V/SMs).
  • Suicidality, including suicide attempts (SA) and suicidal ideation (SI), is a critical outcome following TBI.
  • Understanding predictors of long-term suicidality in this population is essential for effective intervention.

Purpose of the Study:

  • To identify demographic and injury-related factors predicting SA and SI in V/SMs with TBI.
  • To analyze suicidality rates up to 5 years post-TBI within the VA Polytrauma Rehabilitation Center (PRC) network.
  • To inform targeted screening and mental health referrals for at-risk individuals.

Main Methods:

  • A longitudinal observational cohort study involving 812 V/SMs with TBI.
  • Data collected from inpatient rehabilitation at VA PRCs.
  • SA and SI assessed at follow-up points up to 5 years post-injury.

Main Results:

  • SA prevalence ranged from 2.2% to 2.5% annually, with 4.8% reporting at least one SA.
  • SI rates were higher, ranging from 13.2% to 14.3% annually, with 21.7% reporting SI at least once.
  • Younger age (<30), pre-injury mental health treatment/hospitalization, and nonviolent TBI etiology were significant predictors of SA and SI.

Conclusions:

  • Post-TBI suicidality rates among V/SMs are substantial and potentially underestimated.
  • Regular screening for SA and SI is recommended for V/SMs with TBI, even years after injury.
  • Identifying and addressing risk factors can guide interventions to prevent, assess, and treat suicidality.
