Communicating hydrocephalus following stereotactic radiosurgery for periventricular meningiomas: illustrative cases.

Background: Stereotactic radiosurgery (SRS) is a well-established option for the management of intracranial tumors, including meningiomas. Although valued for its low invasiveness and precision, it still carries a risk of complications. Communicating hydrocephalus is a serious, albeit rarely reported, complication of SRS.

The Impact of Electrophysiological Diversity on Pattern Completion in Lithium Nonresponsive Bipolar Disorder: A Computational Modeling Approach.

Introduction: Patients with bipolar disorder (BD) demonstrate episodic memory deficits, which may be hippocampal-dependent and may be attenuated in lithium responders. Induced pluripotent stem cell-derived CA3 pyramidal cell-like neurons show significant hyperexcitability in lithium-responsive BD patients, while lithium nonresponders show marked variance in hyperexcitability. We hypothesize that this variable excitability will impair episodic memory recall, as assessed by cued retrieval (pattern completion) within a computational model of the hippocampal CA3.

Nimodipine ameliorates subarachnoid hemorrhage-induced neuroinflammation and injury by protecting mitochondrial function and regulating autophagy.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke, and the neuroprotective effects of nimodipine following SAH have been well-documented. Sirtuin 3 (SIRT3), a mitochondrial nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, plays a significant role in mitigating oxidative stress in various neurodegenerative conditions. However, the role of SIRT3 in the neuroprotective mechanisms of nimodipine after SAH remains unclear.

Increased serum NfL and GFAP levels indicate different subtypes of neurologic immune-related adverse events during treatment with immune checkpoint inhibitors.

Neurologic immune-related adverse events (nirAEs) represent rare, yet severe side effects associated with immune checkpoint inhibitor (ICI) therapy. Given the absence of established diagnostic biomarkers for nirAEs, we aimed to evaluate the diagnostic utility of serum Neurofilament Light Chain (NfL) and Glial Fibrillary Acidic Protein (GFAP). Fifty-three patients were included at three comprehensive cancer centers, of these 20 patients with manifest nirAEs and 11 patients with irHypophysitis.

Pallidal Spike-Train Variability and Randomness Are the Most Important Signatures to Classify Parkinson's Disease and Cervical Dystonia.

Movement disorders such as Parkinson's disease (PD) and cervical dystonia (CD) are associated with abnormal neuronal activity in the globus pallidus internus (GPi). Reduced firing rate and presence of spiking bursts are typical for CD, whereas PD is characterized by high frequency tonic activity. This research aims to identify the most important pallidal spiking parameters to classify these conditions.

Takotsubo Cardiomyopathy After Subarachnoid Hemorrhage: Who Is At Risk?

Introduction: Takotsubo Cardiomyopathy (TCM) is a rare but well recognized complication of subarachnoid hemorrhage associated with increased morbidity and poor clinical outcomes. There is a scarcity of literature describing the prevalence and risk factors associated with this complication. The aim of this study was to identify patients who are at risk of developing TCM in non-traumatic subarachnoid hemorrhage.

Individualized autoregulation-guided arterial blood pressure management in neurocritical care.

Cerebral autoregulation (CA) is the physiological process by which cerebral blood flow is maintained during fluctuations in arterial blood pressure (ABP). There are various validated methods to measure CA, either invasively, with intracranial pressure or brain tissue oxygenation monitors, or noninvasively, with transcranial Doppler ultrasound or near-infrared spectroscopy. Utilizing these monitors, researchers have been able to discern CA patterns in several pathological states, such as but not limited to acute ischemic stroke, spontaneous intracranial hemorrhage, aneurysmal subarachnoid hemorrhage, sepsis, and post-cardiac arrest, and they have found CA to be altered in these patients.

Aeromedical evacuation of acutely unwell neurosurgical patients from remote, isolated or poorly equipped locations can be considered. This article aims to provide a framework of logistical factors which deserve special consideration in the preparation of these patients for transfer.

Intestine-specific disruption of mitochondrial superoxide dismutase extends longevity.

Reactive oxygen species (ROS) are highly reactive oxygen containing molecules that are generated by normal metabolism. While ROS can cause damage to the building blocks that make up cells, these molecules can also act as intracellular signals that promote longevity. The levels of ROS within the cell can be regulated by antioxidant enzymes, such as superoxide dismutase (SOD), which converts superoxide to hydrogen peroxide.

Puerarin mitigates cognitive decline and white matter injury via CD36-Mediated microglial phagocytosis in chronic cerebral hypoperfusion.

Background: Chronic cerebral hypoperfusion (CCH) contributes significantly to white matter injury (WMI) and cognitive impairment, often leading to vascular dementia (VaD). Inefficient clearance of myelin debris by microglia impedes white matter repair, making microglia-mediated myelin clearance a promising therapeutic strategy for WMI. Puerarin (Pu), an isoflavonoid monomer from Pueraria lobata, is known for its neuroprotective, anti-inflammatory, and immunoregulatory properties.

Knowledge, attitude and perception of epilepsy patients toward epilepsy surgery at Jordan University hospital.

Introduction: Epilepsy is a condition associated with stigma and considerable morbidity, placing a significant burden on patients and their families. It is fundamental to be mindful of the fact that a substantial number of patients remain unaware of the effective surgical procedures that have shown great success in many cases, drawing upon the global underutilization of epilepsy surgery (ES). In this study, we explore the knowledge and attitudes of epilepsy patients towards ES at Jordan University Hospital (JUH).

A multicenter Phase II randomized, placebo-controlled single-blind trial with the SV2A ligand seletracetam in photosensitive epilepsy patients.

The objective of this study was to evaluate the effect of seletracetam (SEL), a potent modulator of synaptic vesicle glycoprotein 2A (SV2A), in patients with photoparoxysmal EEG response (PPR) to intermittent photic stimulation (IPS) as proof-of-principle of efficacy in patients with epilepsy. In this multicenter, single-blind Phase II study, adults with photosensitive epilepsy, with/without concomitant antiseizure medication therapy, underwent IPS under 3 eye conditions (at eye closure, eyes closed and eyes open) after a single oral dose of placebo (day - 1) or SEL (day 1; 0.5, 1, 2, 4, 10, or 20 mg).
