This case describes a 76-year-old male with initial clinical concern for a high-grade glioma, who was ultimately diagnosed with cerebral amyloid angiopathy-related inflammation The patient's presentation included a tonic-clonic seizure followed by aphasia and right-sided hemiparesis. Magnetic resonance brain imaging demonstrated a large left frontal lesion with parenchymal contrast enhancement. Magnetic resonance spectroscopy indicated elevated choline to creatine and choline to N-acetyl aspartate ratios, further suggestive of high-grade glioma.

We show that in the CDW phase, the Fermi arcs reconnect into either closed Fermi loops or Frieze patterns traversing the reconstructed surface mini Brillouin zone. For the closed reconnection topology, application of an out of plane magnetic field leads to a cyclotron motion of the surface electrons.

- Hidden data recovery is important in fields like neurophysiology due to issues with incomplete or corrupted experimental data.
- This study examines the use of reservoir computing (RC) for recovering hidden data from both model systems and real EEG signals, finding that RC is more effective than linear regression (LR) in these cases.
- The research suggests that RC can enhance data recovery processes, leading to improved accuracy and reliability in neurophysiological studies, which is critical for scientific analysis.
Background: It is unknown whether hypertensive microangiopathy or cerebral amyloid angiopathy (CAA) predisposes more to anticoagulant-associated intracerebral hemorrhage (AA-ICH). The purpose of our study was to determine whether AA-ICH is associated with lobar location and probable CAA.
Methods: This was a cross-sectional analysis of patients with first-ever spontaneous ICH admitted to a tertiary hospital in Boston, between 2008 and 2023.
Background And Objectives: The dura mater is a barrier between the brain and the surrounding environment. Injuries to the dura can lead to serious complications, therefore, ensuring a hermetic closure of the dura is a primary task for a neurosurgeon. The aim of the study is to compare the effectiveness of applying the newly developed ViscollDURA collagen membrane (VDCM), with the commercially available Durepair (xenogeneic collagen) in animal model.
