Status epilepticus may cause long-term functional and structural consequences possibly resulting in brain dysfunctions such as chronic epilepsy. In epileptogenesis, the dentate gyrus plays a key role in regulating the excitability of highly vulnerable and potentially epileptogenic downstream structures in the hippocampus proper. One, four and eight weeks after electrically induced status epilepticus, excitability and neuronal degeneration in the rat dentate gyrus were examined with intracerebral electrodes and Fluoro Jade (FJ) staining, respectively. Half of the animals had developed chronic epilepsy by 8 weeks after status epilepticus. Sham-operated controls did not exhibit seizures, and the excitatory parameters remained unchanged. Compared to controls, 8 weeks after status epilepticus the population spike latency in the dentate gyrus was significantly reduced (p<0.05) and substantial neuronal degeneration was seen (p<0.05). In summary, status epilepticus results in functional and morphological alterations in the dentate gyrus likely contributing to epileptogenesis.

Nonconvulsive status epilepticus (NCSE) was initially described in patients with typical and atypical absence status epilepticus (ASE) characterized by states of confusion varying in severity and in focal epilepsies with or without alteration of consciousness. Continuous EEG monitoring of critically ill patients has further refined the classification of NCSE into two main categories: with coma and without coma. Hypnotic, soporific or somniferous epileptic seizures do not exist.

Status epilepticus (SE) is a neurological emergency with significant morbidity and mortality. The role of sex as a factor influencing the characteristics, treatment, and outcomes of SE has been scarcely addressed. This study investigates this variable regarding the clinical management and outcome among adult patients with SE.

Background: Epileptiform activity, including status epilepticus (SE), occurs in up to one-third of comatose survivors of cardiac arrest and may predict poor outcome. The relationship between SE and hypoxic-ischemic brain injury (HIBI) is not established.
Methods: This is a single-center retrospective study on consecutive patients with post-anoxic super-refractory SE.

Purpose: Epilepsia partialis continua (EPC) is form of focal motor status epilepticus, with limited guidelines regarding effective pharmacological management. This systematic review aimed to describe previously utilized pharmacological management strategies for EPC, with a focus on patient outcomes.
Methods: A systematic review of the databases PubMed, EMBASE, and SCOPUS was performed from inception to May 2024.
