We investigated the role of aquaporin-4 in the development of cerebral edema following kainic acid-induced status epilepticus (SE) using specific gravimetry and T2 MRI techniques at 6 h, 1 day, 4 days and 7 days after SE. Our results indicate significantly greater tissue edema and T2 MRI changes in AQP4(-/-) compared to AQP4(+/+) mice that peaks at about 1 day after SE (greater in hippocampus relative to cortex). These results have implications for the mechanisms of edema formation and clearance following intense seizure activity.

Febrile infection-related epilepsy syndrome (FIRES) is a rare clinical presentation of refractory status epilepticus following a febrile infection. This study analyzes data from the NORSE/FIRES Family Registry, an international web-based registry available in six languages with data entered by patients, families, and clinicians to explore clinical presentations, survivorship, and long-term outcomes in adult and pediatric FIRES patients. We characterize and examine differences in demographics, prodromal symptoms, seizure frequency, anti-seizure medications (ASMs), quality of life, cognition, mood, and anxiety in adults vs pediatric populations with FIRES.

Super-refractory status epilepticus (SRSE) is defined as status epilepticus that persists or recurs after treatment with anesthetic agents for more than 24 hours, including cases with recurrent seizures on reduction or withdrawal of anesthetic drugs. Super-refractory status epilepticus presents a significant challenge for neurologists, particularly when standard treatments fail to achieve seizure control. Lacosamide, which has a unique mechanism involving modulating voltage-gated sodium channels by enhancing their slow inactivation, has emerged as a potential option for managing SRSE.

New Onset Refractory Status Epilepticus (NORSE) is a rare and severe condition characterized by refractory seizures in individuals without a prior history of epilepsy. This case report describes a 37-year-old woman diagnosed with anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-positive encephalitis-related NORSE. Her seizures were refractory to multiple interventions, including anti-seizure medications, anesthetics, immunotherapies, a ketogenic diet, and electroconvulsive therapy.

Increasing evidence from fluid biopsies suggests activation and injury of glial cells in epilepsy. The prevalence of clinical and subclinical seizures in neurodegenerative conditions such as Alzheimer's disease, frontotemporal dementia, and others merits review and comparison of the effects of seizures on glial markers in epilepsy and neurodegenerative diseases with concomitant seizures. Herein, we revisit preclinical and clinical reports of alterations in glial proteins in cerebrospinal fluid and blood associated with various types of epilepsy.

Background: Status epilepticus (SE) is a life-threatening state that needs rapid and adequate treatment. Benzodiazepines (BZD) are used as a first-line treatment for SE, and if the desired effect is not achieved, second-line antiseizure medications are used.
Objective: To investigate whether the treatment with BZDs is performed adequately in patients with different subtypes of SE requiring second-line ASM treatment and, if not, to identify the factors influencing the suboptimal treatment.
