Focal-onset seizures account for approximately 40% of seizures in children. Focal seizures are most commonly associated with underlying brain pathology in extreme age groups. Clinical correlation and localizing the site of the lesion play an important role in the early diagnosis and proper management of focal seizures in children.

Abstract Recent work suggests an important role for cortical–subcortical networks in seizure-related loss of consciousness. Temporal lobe seizures disrupt subcortical arousal systems, which may lead to depressed cortical function and loss of consciousness. Extracellular recordings show ictal neocortical slow waves at about 1 Hz, but it is not known whether these simply represent seizure propagation or alternatively deep sleep-like activity, which should include cortical neuronal Up and Down states. In this study, using in vivo whole-cell recordings in a rat model of focal limbic seizures, we d

Background: Evaluating the differential impact of vagus nerve stimulation (VNS) therapy across various seizure types, our study explores its efficacy specifically in patients with categorized minor and major seizures. Methods: We conducted a retrospective cohort study involving 76 patients with pharmacoresistant epilepsy treated at the University Emergency Hospital of Bucharest between 2021 and 2024. Seizures were classified as ‘minor’ (including focal-aware and non-motor/absence seizures) and ‘major’ (including focal to bilateral tonic-clonic and generalized motor seizures), based on modified

Introduction: Evidence of focal electrocortical discharges, with or without evident partial seizures in patients with childhood absence epilepsies (CAE) is rare, but possible. The aim of this study was to establish the frequency of focal electroencephalographic discharges with or without clinical evidence in children with CAE and to explore the clinical course in patients with two types of epileptic seizures: simple absences and partial seizures. Patients and methods: During a 10-year period (1998-2008) we treated and followed-up 66 patients (35 girls and 31 boy), from 1.8 to 13 years of age (

Abstract:
Genetic epilepsy with febrile seizures plus (GEFS+) is characterized by a group of genetic epilepsies associated predominately with an autosomal dominant pattern, but also with de novo and autosomal-recessive inheritance, these last two found in a small number of cases. It was believed that GEFS+ is associated only with generalized seizures, but now the term “genetic epilepsy” is preferred because it has been demonstrated that GEFS+ is associated with both generalized and focal seizures. The “GEFS+ family” was defined as a family with more than two individuals with GEFS+ phenotypes, including

Abstract:
Since the formal characterization of sleep stages, there have been reports that seizures may preferentially occur in certain phases of sleep. Through ascending cholinergic connections from the brainstem, rapid eye movement (REM) sleep is physiologically characterized by low voltage fast activity on the electroencephalogram, REMs, and muscle atonia. Multiple independent studies confirm that, in REM sleep, there is a strikingly low proportion of seizures (~1% or less). We review a total of 42 distinct conventional and intracranial studies in the literature which comprised a net of 1458 patients.

However, it is unclear whether seizures following the same pathway will have the same duration or if these features can vary independently.
