Abstract Introduction Obstructive sleep apnea (OSA) is a risk factor for stroke recurrence and is present in up to 70% of ischemic stroke (IS) survivors. Available data suggest that OSA is not as common in intracerebral hemorrhage (ICH). OSA has been more extensively studied in IS compared to ICH despite higher risk of uncontrolled hypertension, stroke recurrence and stroke mortality in the latter. Furthermore, screening for sleep apnea is suggested after IS or transient ischemic attack (TIA), but not for ICH. We sought to determine whether patients with ICH were as likely to have OSA as compared to IS patients, and to identify differences between indices of OSA between these two groups. Furthermore, we sought to determine whether hospital variables predicted OSA. Methods We identified patients with IS, TIA or ICH referred for polysomnography (PSG) from 01/2013 - 07/2017. Demographic and clinical data were abstracted from medical records. We used t-test, chi squared and Fisher’s exact test as appropriate for univariate analysis and multiple logistic regression for multivariate analysis. Results We identified 82 patients (68% IS, 21% ICH, 11% TIA), of whom 58 (71%) had OSA. Median time from stroke to sleep study was 119 days (IQR 62–244). There was no significant difference between IS/TIA and ICH in OSA prevalence. Only higher Body Mass Index (BMI) was associated with presence of OSA (p
