Background And Objectives: Tumor-related epilepsy is a well-known symptom of glioblastoma. However, the particular characteristics of epileptic seizures related to glioblastoma, ()-wild-type is almost unexplored longitudinally during the whole course of the disease. We assessed tumor-related epilepsy and seizure control during tumor evolution and the prognostic significance of tumor-related epilepsy.

Background: Electroencephalography (EEG) microstates translate resting-state temporal dynamics of neuronal networks throughout the brain and could constitute possible markers of psychiatric disorders. We tested the hypothesis of an increased imbalance between a predominant self-referential mode (microstate C) and a decreased attentional mode (microstate D) in psychosis, mood, and autism spectrum disorders.

Methods: We retrospectively included 135 subjects from an early psychosis outpatient unit, with available eyes-closed resting-state 19 electrodes EEG.

Article Synopsis
  • Scientists looked at brain activity in patients with severe brain injuries to see if they could predict if these patients would wake up.
  • They used special equipment to analyze brain signals and found a new way to measure brain connections that might help doctors make better decisions.
  • The study showed that this new method is linked to patients waking up and recovering, but it still needs to be tested more before being used widely.

Background And Objectives: The association between levetiracetam and survival with isocitrate dehydrogenase () wild-type glioblastomas is controversial. We investigated whether the duration of levetiracetam use during the standard chemoradiation protocol affects overall survival (OS) of patients with wild-type glioblastoma.

Methods: In this observational single-institution cohort study (2010-2018), inclusion criteria were (1) age ≥18 years; (2) newly diagnosed supratentorial tumor; (3) histomolecular diagnosis of wild-type glioblastoma; and (4) standard chemoradiation protocol.

Epilepsies are characterized by recurrent seizures, which disrupt normal brain function. Alterations in neuronal excitability and excitation-inhibition balance have been shown to promote seizure generation, yet molecular determinants of such alterations remain to be identified. Pannexin channels are nonselective, large-pore channels mediating extracellular exchange of neuroactive molecules.
