Prevalence and correlates of post-traumatic stress disorder after ischaemic stroke

Although most often considered a consequence of traumatic event, post-traumatic stress disorder (PTSD) also occurs after illness. The aim of this study was to establish prevalence of PTSD in patients with ischaemic stroke (IS) and its correlation to lesion location, degree of disability, age, gender and marital status. The study included 85 patients with IS. PTSD was diagnosed using a modifed version of the PTSD Checklist Specifc for a stressor (PCL-S). Depression and anxiety were assessed using Hospital Anxiety and Depression Scale (HADS). We defned stroke localisation as right cerebral hemisphere, left cerebral hemisphere, brainstem and cerebellum. Stroke severity was measured using the modifed Rankin scale (mRS). Demographic information including age, gender and marital status was collected from medical history. Of the 85 patients with IS, 11 (12.9%) fulflled PCL-S criteria for PTSD. We found a positive correlation between PTSD and higher degree of disability, P<0.001. Patients with PTSD had lesions more frequently localised in the right cerebral hemisphere and the brainstem. We found no statistically signifcant correlation of PTSD with age, gender and marital status. Our results show that a signifcant number of IS patients develop PTSD after IS. Determining correlates of post- stroke PTSD can help to identify those at higher risk for its development. If proven by additional large sample studies, more patients can beneft from screening for the PTSD symptoms.
