Purpose: Sevoflurane-induced seizures are most often described during mask induction of anesthesia when high concentrations of the volatile agent are administered concomitant with alveolar hyperventilation. The occurrence of seizure-like activity during emergence from sevoflurane anesthesia has been rarely reported.
Clinical Features: We describe a patient who developed several episodes of generalized tonic-clonic seizure-like activity during and immediately after emergence from sevoflurane anesthesia and discuss the potential factors that contributed to this unusual complication. The patient was treated with intravenous propofol, midazolam, and phenytoin and required intensive care management before his neurologic status stabilized.
Conclusion: The report emphasizes that sevoflurane is capable of producing excitatory central nervous system (CNS) phenomena in spite of causing primarily CNS depressant effects.

: Ongoing challenges in epilepsy therapy warrant research on alternative treatments that offer improved efficacy and reduced side effects. Designed to enhance mitochondrial targeting and increase bioavailability, mitocurcumin (MitoCur) was evaluated for the first time as an antiepileptic agent, with curcumin (Cur) and sodium valproate (VPA), a standard antiepileptic drug, included for comparison. This study investigated the effects on seizure onset, severity, and progression in a zebrafish model of pentylenetetrazole (PTZ)-induced seizures and measured the concentrations of the compounds in brain tissue.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.

Introduction: Propofol is an anesthetic agent commonly used in emergency department (ED) procedural sedation. It is often preferred in orthopedic procedures because of its muscle-relaxing properties. Rarely, however, it can induce agitation and muscle hypertonicity.

Complex genetic architecture is the major cause of heterogeneity in epilepsy, which poses challenges for accurate diagnosis and precise treatment. A large number of epilepsy candidate genes have been identified from clinical studies, particularly with the widespread use of next-generation sequencing. Validating these candidate genes is emerging as a valuable yet challenging task.

Tumor associated epilepsy is a common and debilitating co-morbidity of brain tumors, for which inadequate treatments are available. Additionally, animal models suggest a potential link between seizures and tumor progression. Our group has previously described a mouse model of diffusely infiltrating glioma and associated chronic epilepsy.
