Introduction: Stroke is a leading cause of disability worldwide with grave morbidity and mortality. Sleep and stroke have a definite intermingling neuropathological relationship, so along with expeditious acute management, efficient secondary prevention and consistent rehabilitation, sleep disorders' management has a hand in offering a medical service up to the mark. Objective: Screening of sleep disorders' prevalence in patients who survived a previous stroke by applying simple questionnaires and to determine the correlation between these disorders and stroke's demographic, clinical, and risk factor variables. Methods: Cross-sectional prospective study on 75 stroke patients from stroke outpatient clinic and all patients were subjected to answer a sheet of sleep questionnaire, Pittsburg Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Apnea/Hypopnea Index (AHI), Arabic versions. Results A total of 70.6 % were found to have sleep disorders, 61.6% had poor sleep quality, 20% had a severe degree of excessive day time sleepiness (EDS). Sleep disorders were more prevalent in the moderate severity of stroke by NIHSS and in the first 1-4 weeks. There was no correlation between the occurrence of sleep disorders and the site of the lesion. Conclusion: Sleep disorders are broadly prevalent after a stroke. Resulting damage impedes the functional outcome. Simple questionnaires are easy applicable methods for screening of such disorders in post-stroke patients. Guidelines needed regarding screening and management of sleep disorders after a stroke.

Background Coronavirus disease 2019 (COVID-19) is a pandemic disease which predominantly affects the respiratory system with high critical care mortality and morbidity, yet it also causes multiple organs dysfunction in affected patients. There is a strong evidence that it increases the susceptibility of cerebrovascular strokes in such patients. Besides this prothrombotic complication, arterial dissection can be one of its mechanisms increasing the risks of stroke. Case presentation Herein, we report a case of spontaneous isolated subclavian artery dissection in a COVID-19 patient. Sixty-one-year-old female presented with spontaneous isolated subclavian artery dissection without any traumatic events nor history of connective tissue disorders. She had left upper limb ischemia followed by cerebellar, thalamic and occipital infarctions. Whether this patient’s subclavian artery dissection was triggered by exaggerated inflammatory response or arteriopathy secondary to COVID-19 remains speculative. Conclusions Nonetheless, arterial dissection can be one of its complications, it is essential for treating physicians to be attentive for the diversity of COVID-19 clinical manifestations.
