Impact of Post-Stroke Post-Traumatic Stress Disorder.

Introduction: Post-Traumatic Stress Disorder (PTSD) is associated with exposure to traumatic events, especially in the military setting. However, patients who experience stroke may develop anxiety about their stroke event and may re-experience transient neurological symptoms as a result. A significant portion develop the persistent and disabling symptoms of PTSD.

Methods: At the University of South Florida, we conducted a single-center, IRB-approved, observational pilot study of 20 adult patients who were diagnosed with stroke or transient ischemic attack (TIA) in the previous 31 days to 1 year. Patients completed the post-traumatic stress disorder checklist-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), Stroke specific Quality of Life Scale (SS-QOL-12), Modified Rankin Scale of disability (mRS), and National Institutes of Health Stroke Scale (NIHSS) and provided blood and saliva samples.

Results: All 20 subjects completed the PCL-5 and 19 subjects completed the follow up scales. Seven patients (35%) were found to have Post-Stroke Post-Traumatic Stress Disorder (PS-PTSD). Higher PCL-5 scores were significantly correlated with lower SS-QOL scores indicating worse quality of life (r = -0.709, P = .001) and higher PHQ-9 scores representing symptoms of depression (r = 0.727, P < 0.001).

Conclusion: Post-Stroke Post-Traumatic Stress Disorder (PS-PTSD) is prevalent after stroke and TIA with patients experiencing concurrent depressive symptoms, correlating with a worsened quality of life.
