Summary
Post-traumatic stress disorder (PTSD) affects over a third of patients after subarachnoid hemorrhage (SAH). This condition significantly impacts quality of life and is linked to various risk factors.
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.
