Background: Temporal lobe epilepsy (TLE) is the most common form of drug-resistant epilepsy, often associated with hippocampal sclerosis (HS), which involves selective neuronal loss in the Cornu Ammonis subregion 1 CA1 and CA4 regions of the hippocampus. Granule cells show migration and mossy fiber sprouting, though the mechanisms remain unclear. Microglia play a role in neurogenesis and synaptic modulation, suggesting they may contribute to epilepsy.

We investigated whether virtual reality (VR) training can significantly reduce some of these fears and improve surgical education for medical students.
Methods: We randomly divided a group of 24 medical students and investigated the effects of a VR application (digitally recreated operating theatre tour) and compared it with currently-in-use written instructions for operational tasks in the operating theatre.

Background: COVID-19 has attracted global attention primarily because of the severe acute respiratory symptoms associated with it. However, nearly one third of the patients also present with neurologic symptoms. This report describes a case of a previously healthy woman with acute COVID-19 infection, who developed acute facial nerve palsy and rapid progression to coma due to otogenic brain abscess.

It can contribute not only to physical rehabilitation but also to psychological well-being. This study aims to evaluate the rate of return to work following elective lumbar spine surgery and identify predictors that predict failure of return to work.

Objective: To assess the effect of seizure frequency, the extent of resection, and cognitive function on the psychobehavioral outcome of patients after temporal lobe surgery for pharmacoresistant epilepsy.
The COVID-19 (coronavirus disease) pandemic had a severe impact on public health worldwide. A rare but serious complication after administration of adenoviral vaccines against SARS-CoV-2 (AstraZeneca-Oxford and Johnson & Johnson) is vaccine-induced immune thrombotic thrombocytopenia and thrombosis (VITT), which can lead to serious complications such as cerebral venous sinus thrombosis (CVST). CVST itself can cause subarachnoid hemorrhage (SAH) and/or intracerebral hemorrhage (ICH), leading to high mortality due to herniation of brain parenchyma.

Dual blockade led to HIF1α upregulation and CalR translocation, accompanied by massive impairment of mitochondrial function. Basal oxygen consumption rate, ATP synthesis, and maximal mitochondrial respiration decreased, confirming disrupted endoplasmic reticulum-mitochondrial homeostasis.

While in high-grade glioma, a surgical resection of the tumor mass is a fundamental part of current standard regimens, in brain metastasis, the burden of the primary tumor must be considered. However, without a cancer history, the differentiation remains challenging in the imaging.

FPP is characterized by symmetric perforations on either side of the skull, which are caused by insufficient ossification during embryogenesis. These openings are typically abnormally large and can range from a few millimeters to several centimeters in diameter.

However, there is no universal definition of swelling and/or infarct volume(s) available to support a decision for surgery.
Objective: To evaluate functional outcomes in surgically compared with conservatively managed patients with cerebellar infarcts.
Background incidence of pyogenic spinal infections has increased in recent years. In addition to treating the spinal infection, optimal care also includes identifying the source of the pyogenic spinal infection and the presence of other infections. The aim of this study is to elucidate the prevalence of oral cavity infection (OCI) within this patient cohort.

The aim of this study was to verify the efficacy and safety of this minimal invasive procedure.
Methods: This retrospective study comprises 1000 patients who were treated with TDT under local anesthesia at bedside due to chronic subdural hematoma (cSDH), intracerebral hemorrhage (ICH), and hydrocephalus (HYD) as a result of subarachnoid hemorrhage or non-hemorrhagic causes, increased intracranial pressure (IIP) in traumatic brain injury or non-traumatic brain edema, and other pathologies (OP) requiring drainage.
Purpose: Chat generative pre-trained transformer (GPT) is a novel large pre-trained natural language processing software that can enable scientific writing amongst a litany of other features. Given this, there is a growing interest in exploring the use of ChatGPT models as a modality to facilitate/assist in the provision of clinical care.
Methods: We investigated the time taken for the composition of neurosurgical discharge summaries and operative reports at a major University hospital.
Background: Temporal muscle thickness (TMT) on cranial CT scans has recently been identified as a prognostic imaging parameter for assessing a patient's baseline frailty. Here, we analyzed whether TMT correlates with Traumatic brain injury (TBI) severity and whether it can be used to predict outcome(s) after TBI.
Methods: We analyzed the radiological and clinical data sets of 193 patients with TBI who were admitted to our institution and correlated the radiological data with clinical outcomes after stratification for TMT.
Objective: To assess transcranial sonography (TCS) as stand-alone tool and in combination with microelectrode recordings (MER) as a method for the postoperative localization of deep brain stimulation (DBS) electrodes in the subthalamic nucleus (STN).
Methods: Individual dorsal and ventral boundaries of STN (n = 12) were determined on intraoperative MER. Postoperatively, a standardized TCS protocol was applied to measure medio-lateral, anterior-posterior and rostro-caudal electrode position using visualized reference structures (midline, substantia nigra).
Glioblastoma is the most common primary brain cancer in adults and represents one of the worst cancer diagnoses for patients. Suffering from a poor prognosis and limited treatment options, tumor recurrences are virtually inevitable. Additionally, treatment resistance is very common for this disease and worsens the prognosis.

Furthermore, low temporal muscle thickness (TMT) has recently been identified as a prognostic imaging parameter to assess patient frailty and outcome. We analyzed radiological and clinical data sets of 282 patients with cerebellar ischemic stroke.

Therefore, we aimed to evaluate whether invasive subdural electroencephalogram recording leads to earlier seizure detection and treatment initiation in patients with aSDH.
Design: Prospective, single-center, cohort trial.
Purpose: The most frequent therapy of hydrocephalus is implantation of ventriculoperitoneal shunts for diverting cerebrospinal into the peritoneal cavity. We compared two adjustable valves, proGAV and proGAV 2.0, for complications resulting in revision surgery.

Sodium channel blockers are effective for seizure control in common forms of epilepsy, but loss of sodium channel function underlies some genetic forms of epilepsy. Approaches that provide bidirectional control of sodium channel expression are needed.

However, we experienced reproducible falsely high ICP measurements when the ICP probe was inserted into the intracerebral hematoma cavity. Thus, the aim of the experimental and translational study was to analyze the influence of ICP probe placement with regard to measured ICP values.
