We describe a patient who entered a stuporous state after receiving benzodiazepine treatment for generalized tonic-clonic status epilepticus. A diagnosis of generalized NCSE with tonic seizures was made on the basis of the clinical picture and response to barbiturate anaesthetic, although the EEG pattern was not typical of the changes previously described in tonic seizures-tonic status epilepticus. This report discusses the differential diagnosis of postictal stupor, nonconvulsive status epilepticus with tonic seizures and sedation caused by the emergency treatment of status epilepticus, and summarizes the literature on tonic seizures and tonic status epilepticus.

Heterozygous pathogenic variants in MBD5 (MIM*611472) and CCM2 (MIM*607929) cause autosomal dominant intellectual developmental disorder 1 (MIM#156200) and cerebral cavernous malformations-2 (MIM#603284), respectively. Both conditions may present with seizures, epilepsy, and status epilepticus. However, super-refractory status epilepticus, defined as seizures lasting more than 24 h, has not been described in either condition.

Objectives: Pediatric status epilepticus (SE) carries a high risk of morbidity and mortality and can result in neurologic injury. Establishing seizure activity on conventional EEG (cEEG) is essential but can delay treatment of seizures due to technician limitations. Rapid response EEG (rrEEG) device Ceribell and its Brain Stethoscope function can be used and interpreted rapidly by bedside providers with minimal training.

Contemporary studies report nonconvulsive status epilepticus (NCSE) in Creutzfeldt-Jakob disease (CJD), based on benzodiazepine (BZP)-responsive epileptiform discharges on the electroencephalogram (EEG), with the following false syllogism: (1) intravenous (IV) administration of BZPs usually suppress ictal activity in NCSE; (2) in CJD, periodic sharp wave complexes (PSWCs) are suppressed by IV BZPs; (3) therefore, these patients have NCSE. This is a simplistic and invalid conclusion, because authors of 20th-century science reports have clearly shown that IV BZPs, short-acting barbiturates, and drugs with no antiseizure effects, such as chloral hydrate and IV naloxone, suppress PSWCs, but patients fall asleep with no clinical improvement. In contrast, IV methylphenidate transiently improves both the EEG and clinical states.

Background: Ampicillin/sulbactam (ABPC/ SBT) is one of the most common β-lactam antibiotics for patients with status epilepticus complicated with aspiration pneumonia. It is known that β-lactam antibiotics such as penicillin aggravate epileptic seizures or status epilepticus. Here, we investigated whether ABPC/SBT aggravates seizures using electroencephalography (EEG) monitoring.

Purpose: Proton exchange rate (K) is a valuable biophysical metric. K MRI may augment conventional structural MRI by revealing brain impairments at the molecular level. This study aimed to investigate the feasibility of K MRI in evaluating brain injuries at multiple epilepsy stages.
