Clinical and tomographic examinations of 40 patients with aphasia developed after an ischemic stroke were carried out. In more than half of them no correlation between the aphasia gravity and character on the one hand, and the size and localization of the ischemic focus (or foci) in the brain on the other was noted. With similar character and gravity of the speech disorder the size and localization of the ischemic foci may be different, ad vice versa. It has been shown that the interrelations between the focal pathology of the brain and the character and gravity of speech disorders are very complicated. One should take into consideration the possibility of individual organization of the speech functions, the degree of the speech activity automatism before the disease, and the state of the cerebrovascular system as a whole.

Background: Carotid webs are rare nonatherosclerotic disorders in the carotid artery and are increasingly recognized as factors of ischemic stroke in the young population. Asymptomatic webs can be treated with antithrombotic therapy, whereas symptomatic cases frequently require surgical interventions, including carotid endarterectomy (CEA). However, guidelines for the optimal timing of these treatments remain unestablished, especially compared to atherosclerotic stenotic lesions, due to the rarity of carotid webs.

Background: Total intravenous anesthesia (TIVA)-based and volatile-based general anesthesia have different effects on cerebral hemodynamics. The current work compares these 2 regimens in acute ischemic stroke patients undergoing endovascular therapy.
Methods: We conducted a systematic literature search across MEDLINE, Embase, Cochrane, CINAHL, Web of Science, and Scopus.

High concentrations of neutrophil degranulation products in the plasma and thrombi are poor prognostic indicators in patients with acute ischemic stroke (AIS). This study aimed to identify candidate effectors capable of mediating neutrophil degranulation post-AIS, and to reveal their underlying epigenetic mechanisms. Microarrays and ChIP-seq were applied to analyze the neutrophils of patients with AIS.

Stroke is a leading cause of death and disability worldwide. Most cases of stroke are ischemic and result from the occlusion of the middle cerebral artery (MCA). Current pharmacological approaches for the treatment of ischemic stroke are limited; therefore, novel therapies providing effective neuroprotection against ischemic injury following stroke are urgently needed.

Recent guidelines for acute ischemic stroke (AIS) indicate administration of intravenous thrombolysis (IVT) in patients receiving direct oral anticoagulants (DOAC) is not firmly established and may be harmful unless certain potential parameters are met. This systematic review and meta-analysis explores safety outcomes and other clinical parameters from the growing number of publications describing patients taking a DOAC who experience an AIS that is treated acutely with IVT alone. Embase, International Pharmaceutical Abstracts, and PubMed were searched up to January 9, 2024 for studies including adult patients taking a DOAC who experienced an AIS treated with IVT and did not undergo endovascular therapy (EVT), regardless of the use of an anticoagulation reversal agent.
