Objective: To study serum levels of melatonin in children with epilepsy or febrile seizures in order to provide a basis for the treatment of epilepsy or febrile seizures with melatonin.
Methods: Serum melatonin levels were measured using ELISA in 15 children with simple febrile seizure (SFS), in 15 children with complex febrile seizure (CFS), in 15 children with epilepsy, and in 15 children with upper respiratory infections (control group).
Results: Serum melatonin levels in children with epilepsy (8.66+/-1.38 ng/L) or CFS (14.91+/-2.61 ng/L) were significant lower than those in the control group (23.93+/-2.01 ng/L) (P<0.01). The SFS group showed lower serum melatonin levels (20.72+/-2.54 ng/L) compared with the control group, but there were no statistical differences between the two groups. Serum melatonin levels in the epilepsy group were significantly lower than those in the CFS (P<0.05) and the SFS groups (P<0.01).
Conclusions: Serum melatonin levels decreased in children with epilepsy or CFS. Supplement of exogenous melatonin might be a promising treatment for epilepsy and febrile seizures in children.

Epilepsy is the most common chronic neurological condition in children. Many barriers exist in early recognition which cause delay in care and impact quality of life. Some of these children require advanced treatments which are underutilized due to lack of education, awareness and referrals.

-related disorder (SRD) is a developmental and epileptic encephalopathy caused by a disruption of the gene. At the beginning of 2024, it is one of many rare monogenic brain disorders without disease-modifying treatments, but that is changing. This article chronicles the last 5 years, beginning when treatments for SRD were not publicly in development, to the start of 2024 when many SRD-specific treatments are advancing.

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type.

Introduction: The megalencephaly capillary malformation polymicrogyria (MCAP syndrome) results from mosaic gain-of-function variants. The main clinical features are macrocephaly, somatic overgrowth, neurodevelopmental delay and brain anomalies. Alpelisib (Vijoice) is a recently FDA-approved PI3Kα-specific inhibitor for patients with PIK3CA-related overgrowth spectrum (PROS).

Excitation-inhibition (E/I) imbalance is theorized as a key mechanism in the pathophysiology of epilepsy, with ample research focusing on elucidating its cellular manifestations. However, few studies investigate E/I imbalance at the macroscale, whole-brain level, and its microcircuit-level mechanisms and clinical significance remain incompletely understood. Here, the Hurst exponent, an index of the E/I ratio, is computed from resting-state fMRI time series, and microcircuit parameters are simulated using biophysical models.
