Despite the high incidence of epilepsy in very young children, the availability of approved antiepileptic drugs for this population is limited. This study assessed the efficacy and tolerability of levetiracetam in children younger than 2 years of age with various types of epilepsy. A single-center, retrospective chart review of 28 patients ranging in age from 2 weeks to 22 months treated with levetiracetam over a 2.5-year period was conducted. The mean dosage of levetiracetam was 39 mg/kg per day, and the mean duration of treatment was 6.3 months. The majority of patients (54%) were also taking 1 or 2 other antiepileptic drugs. A reduction in seizure frequency was found in 54%, with 14% achieving seizure freedom. Eight patients showed no response to levetiracetam treatment. Efficacy was highest among patients with generalized epilepsy. Adverse effects occurred in 2 patients and were behavioral in nature. Levetiracetam treatment was safe and effective in this group of very young patients with various types of epilepsy.

Abdominal pain as a novel manifestation in children with PCDH19-related epilepsy: A case report.
Medicine (Baltimore)
January 2025
Department of Neonatal, Children's Hospital Affiliated to Shandong University/Jinan Children's Hospital, Jinan, Shandong, China.
Rationale: PCDH19-related epilepsy manifested various clinical features, including febrile epilepsy, with or without intellectual disability, and psych-behavioral disorders. However, there are few studies demonstrating abdominal pain as the first symptom.
Patient Concerns: A 3-year-old Chinese girl presented with clustered seizures of fever sensitivity accompanied by abdominal pain.
A Longitudinal Exploration of -Related Hemiplegic Migraine in Children Using Electronic Medical Records.

February 2025
Division of Neurology, Children's Hospital of Philadelphia, PA.
Background And Objectives: Since the initial description of related hemiplegic migraine (HM), the phenotypic spectrum has expanded from mild episodes in neurotypical individuals to potentially life-threatening events frequently seen in individuals with developmental and epileptic encephalopathies. However, the overall longitudinal course throughout childhood remains unknown.
Methods: We analyzed HM and seizure history from electronic medical records in individuals with -related HM, delineating frequency and severity of events in monthly increments through a standardized approach.

Neurophysiopathology Unit, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy.
Introduction: Biallelic variants in QARS1, a house-keeping gene involved in protein synthesis, cause a rare encephalopathy classically characterized by severe developmental delay, drug-resistant neonatal-onset epilepsy, microcephaly, and brain atrophy. We aim to raise awareness on mild QARS1-related phenotypes describing a 6-year-old patient.
Case Description: Epilepsy onset occurred at 3.

Generalized Convulsive status epilepticus (SE) is a neurological emergency because prolonged convulsions can cause respiratory compromise and neuronal injury. Compromised GABA-mediated inhibition is a defining feature of SE, and many current therapies are benzodiazepines, which are allosteric modulators of GABA-A receptors. Many patients with medically refractory epilepsy are at risk for SE.

Objective: The aim of the study was to evaluate the effects of commonly used medications for epilepsy on thyroid function tests in children.
Methods: Epileptic children treated with valproic acid, levetiracetam, carbamazepine, and oxcarbazepine were retrospectively examined along with a healthy control group. Levels of free thyroxine 4 and thyroid-stimulating hormone were compared.
