  Evidences are escalating on the diverse neurological disorders associated with COVID-19 pandemic. The theoretical discovery of Sanal flow choking is a paradigm shift in the diagnostic science of asymptomatic stroke causing neurological disorders in earth and at the microgravity condition (human spaceflight). A critical review has been carried out herein for correlating the phenomenon of Sanal flow choking (PMCID: PMC7267099) and hemorrhagic stroke. Herein, we show that when systolic to diastolic blood pressure ratio (BPR) reaches the lower critical hemorrhage index (LCHI) the internal flow choking and shock wave generation occurs in the downstream region of the vessels, with sudden expansion, divergence, bifurcation, stenosis and/or occlusion, leading to pressure overshoot causing brain hemorrhage and/or neurological disorders. The critical BPR for internal flow choking is uniq.. Read More»
