The increasing prevalence of pathological cerebrovascular conditions, including stroke, hypertensive encephalopathy, and chronic disorders, underscores the importance anesthetic considerations for affected patients. Preserving cerebral oxygenation blood flow during anesthesia is paramount to prevent neurological deterioration. Furthermore, protecting vulnerable neurons from damage crucial optimal outcomes. Recent research suggests that agents may provide a potentially therapeutic approach managing conditions. Anesthetics target neural mechanisms underlying dysfunction, thereby modulating neuroinflammation, against ischemic injury, improving hemodynamics.

Abstract Background Migraine with aura (MA) is a hallmark feature of CADASIL, hereditary small-vessel disease caused by NOTCH3 mutations. While MA prevalent in its underlying mechanisms remain unclear, and the links observed can be questioned or debated. This study examined prevalence, clinical characteristics, pathophysiology patients CADASIL. Methods Clinical experimental data were reviewed to assess sex differences, pathophysiological insights from CADASIL models confirm indisputable between migraine this unique genetic model cerebral small vessel disease. Results was 10–20 times more than general population, frequent atypical prolonged auras. The altered distribution delayed onset suggest disease-specific mechanisms. Experimental also revealed heightened susceptibility cortical spreading depression (CSD) preclinical models, linked greater fragility maintaining ionic homeostasis. Conclusion high prevalence distinct features, as well obtained at level, strongly support causal relationship mediated neurovascular dysfunction Accumulating condition sheds new light on much-debated cerebrovascular diseases.

Abstract Traumatic brain injury (TBI) has emerged as a significant risk factor for Alzheimer’s disease (AD), complex and devastating neurodegenerative disorder characterized by progressive cognitive decline memory loss. Both conditions share common feature: blood‒brain barrier (BBB) dysfunction, which is believed to play pivotal role in linking TBI the development of AD. This review delves into intricate relationship between AD, with focus on BBB dysfunction its critical mechanisms therapeutic development. We first present recent evidence from epidemiological studies highlighting increased incidence AD among individuals history TBI, well pathological animal model that demonstrate how can accelerate AD-like pathology. Next, we explore may mediate TBI-induced Finally, investigate shared molecular pathways associated both discuss latest findings targeting these employing regenerative approaches, such stem cell therapy pharmacological interventions, enhance function mitigate neurodegeneration.

Abstract In recent years, increasing evidence has suggested that meningeal lymphatic drainage plays a significant role in central nervous system (CNS) diseases. Studies have indicated CNS diseases and conditions associated with dysfunction include neurodegenerative diseases, stroke, infections, traumatic brain injury, tumors, functional cranial disorders, hydrocephalus. However, the understanding of regulatory damage mechanisms lymphatics under physiological pathological is currently limited. Given importance profound interplay between this review covers seven key aspects: development structure vessels, methods for observing lymphatics, function molecular relationships vessels potential conclusions outstanding questions. We will explore relationship development, structure, current both animal models humans, identify unresolved points research. The aim to provide new directions future research therapeutic strategies targeting by critically analyzing advancements field, identifying gaps knowledge, proposing innovative approaches address these gaps.

Abstract Spreading depolarization (SD) temporarily shuts down neural processing in nervous systems with effective blood brain barriers. In mammals this is usually pathological response to energetic stress. insects a very similar process induced by abiotic environmental stressors and can be beneficial conserving energy. Age critical factor for predicting the consequences of SD humans. We investigated effect aging on an insect model explored contribution oxidative Aging slowed recovery intact locusts from asphyxia water submersion. semi-intact preparations we monitored recording DC potential across barrier bath application Na + /K -ATPase inhibitor, ouabain.

Abstract Traumatic brain injury (TBI) is a major global health concern, affecting more than 40 million people annually. While most cases are mild and present with light symptoms, repeated injuries can result in delayed pathologies, including cognitive decline, neuropsychiatric complications, post-traumatic epilepsy (PTE). PTE refers to recurring, unprovoked seizures occurring at least one week after TBI. the link between moderate severe TBI well established, epileptogenesis repetitive (rmTBI) seldom studied. Currently, there no biomarkers identify those risk of developing PTE, its diagnosis challenging. Here, we used rat model study following rmTBI assessed human EEG data potential for PTE. We employed closed head induce rmTBI, recorded activity using electrocorticography (ECoG) 2- 6-months post-injury. Behavioral assessments post-mortem analysis were also conducted. In humans, analyzed recordings from Temple University database investigate EEG-derived features diagnosing At 6 months post injury, 70% animals developed compared 22% control group (P=0.01). neurological did not predict paroxysmal slow wave events (PSWEs) found be reliable biomarker prediction. percentage time PSWEs was significantly elevated patients epileptiform activity. conclusion, suggest as non-invasive, cost-effective rodents patients.
