Abstract WP61: Impact Of Post-stroke Post Traumatic Stress Disorder On Quality Of Life

Introduction: After an ischemic stroke or transient ischemic attack (TIA), patients may have post-event anxiety and re-experience transient neurological symptoms. However, some stroke patients develop persistent and disabling symptoms of post-traumatic stress disorder (PTSD). Data on post-stroke post-traumatic stress disorder (PS-PTSD) is sparse. Methods: We conducted a single-center observational pilot study of 20 adult patients diagnosed with stroke or TIA in the previous 31 days to 1 year. Patients completed the PTSD Check List-5 (PCL-5), Patient Health Questionnaire-9 (PHQ-9), stroke specific Quality of Life Scale-12 (SS-QOL-12), modified Rankin Scale of disability, and the National Institutes of Health Stroke Scale. The PCL-5 is a 20 item self-report score assessing symptoms of re-experiencing (Criterion B), avoidance (Criterion C), negative alterations in cognition or mood (Criterion D), and hyperarousal (Criterion E). Subjects were classified as having PS-PTSD with PCL-5 score ≥33 or endorsement of moderate symptoms in at least one B item, one C item, two D items, and two E items. Results: Twenty patients completed the PCL-5 and 19 completed the follow up scales. Seven patients (35%) were found to have PS-PTSD. Higher PCL-5 scores were significantly correlated with lower SS-QOL12 scores indicating worsened quality of life (r= -0.709, P=.001) and higher PHQ9 scores representing more depressive symptoms (r= 0.727, P<0.001). The effect was most prominent in the SS-QOL-12 domains of mood, language, upper extremity function, and family roles (Table 1). Conclusion: PS-PTSD was found to be prevalent after stroke and TIA with 35% of patients having significant PTSD symptomology. These patients were also more likely to have concurrent depressive symptoms and worsened quality of life.
