<h3>Background and Objectives</h3> Declines in stroke admission, IV thrombolysis (IVT), mechanical thrombectomy volumes were reported during the first wave of COVID-19 pandemic. There is a paucity data on longer-term effect pandemic over course year through second We sought to measure admissions, intracranial hemorrhage (ICH), IVT, 1-year period at onset (March 1, 2020, February 28, 2021) compared with immediately preceding 2019, 29, 2020). <h3>Methods</h3> conducted longitudinal...

Summary Important brainstem regions are involved in the regulation of rapid eye movement sleep. We hypothesized that stroke is associated with dysregulated sleep and related muscle activity. compared quantitative/qualitative polysomnography features activity (any, phasic, tonic) between 15 patients ( N = 46 periods), 16 lacunar/non‐brainstem 40 healthy controls 62 Parkinson's disease polysomnography‐confirmed behaviour disorder. Further, group, we performed a magnetic resonance imaging‐based...

Background: We developed an automated smart phone application for detection of acute stroke using machine learning (ML) algorithms recognition facial asymmetry, arm weakness, and speech changes. Methods: analysed prospectively collected data from patients admitted to 4 major metropolitan centers with confirmed diagnosis stroke. Speech were captured via video recording was device sensors. A. Face. This module extracts 68 landmark points that are passed through a dimensionality reduction step...
