Question: Does epilepsy affect neurocognitive functions in pediatric drug-resistant focal epilepsy?
Finding: Diffusion magnetic resonance imaging (MRI) connectome could identify new imaging markers for seizure-associated structural abnormalities. New markers reflect deviations of local efficiency in neurocognitive networks and provide outstanding discretionary capacity for neurocognitive impairments, achieving an accuracy range of 90%–98% in the independent test patients.
Meaning: Supplementary MRI-driven decisions could be performed for personalized interventions to mitigate long-term neurocognitive effects.

∙ Rotavirus infection-associated central nervous system (CNS) complications are fairly common in children.
∙ Common clinicoradiological features include benign convulsions with mild gastroenteritis, acute encephalopathies/encephalitis, cerebellitis, and neonatal rotavirus-associated leukoencephalopathy.
∙ Possible mechanisms for CNS complications include direct viral invasion into the brain via several potential routes such as the blood-brain barrier and vagus nerve, and entry of various brain-damaging mediators and activated immune cells into the brain.

-
∙ The main pathogen for benign convulsions with mild gastroenteritis (CwG) was previously rotavirus; however, cases associated with norovirus are increasing.
∙ CwG is characterized by clustered generalized seizures. Electroencephalography and magnetic resonance imaging show transiently abnormal findings in the acute phase that eventually normalize with progression. Its prognosis is good, and long-term treatment is unnecessary.
∙ There are many reports on the pathophysiological mechanism of CwG, which remains unclear.

· Neonatal seizures are often electrographic-only seizures without clinical signs; therefore, the identification of electrical seizure activity on electroencephalography is the gold standard for diagnosis.
· Clinical signs of neonatal seizures are divided into motor or nonmotor seizures, and motor seizures are mostly focal or multifocal.
· Most neonatal seizures are caused by acute symptomatic etiologies, but in cases of intractable seizures, structural, genetic, or metabolic etiologies should be investigated.
