Post-traumatic Stress Disorder

79
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,...

Area of Science:

  • Neurology
  • Psychiatry
  • Systematic Review

Background:

  • Post-traumatic stress disorder (PTSD) is a common and debilitating consequence following neurological events like subarachnoid hemorrhage (SAH).
  • Understanding the prevalence, severity, and progression of PTSD after SAH is crucial for patient care.

Approach:

  • A systematic review critically appraised literature from PubMed, EMBASE, PsycINFO, and Ovid Nursing.
  • Included 17 English-language studies with 1,381 adult participants diagnosed with PTSD post-SAH.

Key Points:

  • PTSD prevalence ranged from 1% to 74%, with a weighted average of 36.6% across studies.
  • Risk factors include premorbid psychiatric disorders, neuroticism, maladaptive coping, comorbid depression/anxiety, and stress from post-ictal events.
  • Effective social support networks were associated with a lower risk of PTSD.

Conclusions:

  • PTSD is highly prevalent in SAH patients, negatively impacting their quality of life.
  • Further research is needed on the temporal progression, chronicity, and neurobiological correlates of post-SAH PTSD.
  • Call for more randomized controlled trials to investigate these aspects.
