Purpose: To present a retrospective study of 13 children with benign epilepsy with centrotemporal spikes (BECTS), also known as benign rolandic epilepsy (BRE), associated with generalized spikes and waves as the only EEG manifestation at onset.
Method: Charts of children with typical clinical criteria of BRE electroclinically followed-up between February 2000 and February 2015 were reviewed.
Results: Among 309 patients who met the electroclinical criteria of BRE, we identified 13 children who presented with the typical clinical manifestations but who, on the EEG, only had generalized paroxysms at onset that continued along the course of the syndrome. Generalized spike-and-wave discharges were observed in all patients when awake and during sleep (100%). During the evolution no particular electroclinical pattern was observed. The patients responded well to antiepileptic drugs, such as valproic acid and levetiracetam. Outcome was good in all patients.
Conclusions: We found evidence that patients with BRE may have generalized EEG discharges at onset as the sole manifestation lasting throughout the course of the syndrome. In some, focal paroxysms developed later. The course was benign. In our group of patients, clinical features and evolution were similar to those of typical cases of BRE. Response to valproic acid and levetiracetam was found to be particularly good.

Objective: This study aims to explore differences in the static and dynamic amplitude of low-frequency fluctuations (sALFF and dALFF) in resting-state functional MRI (rs-fMRI) data between patients with Benign childhood epilepsy with centrotemporal spikes (SeLECTS) and healthy controls (HCs).
Materials And Methods: We recruited 45 patient with SeLECTS and 55 HCs, employing rs-fMRI to assess brain activity. The analysis utilized a two-sample t-test for primary comparisons, supplemented by stratification and matching based on clinical and demographic characteristics to ensure comparability between groups.

Article Synopsis
- BECTS is a type of epilepsy in children that can harm thinking skills, especially when it's worsened by another condition called ESES.
- The study looked at brain activity in kids with BECTS-ESES and compared it to healthy kids to see how their brains connect and if it was related to their learning problems.
- Researchers found that kids with BECTS-ESES had different brain connections that could explain why they struggle with things like memory and attention, highlighting the importance of the Salience Network in understanding their cognitive issues.
Structure-function interrelationships and associated neurotransmitter profiles in drug-naïve benign childhood epilepsy with central-temporal spikes patients.

Department of Radiology, The Affiliated Hospital of Zunyi Medical University, Zunyi, China.
Objectives: To explore the interrelationships between structural and functional changes as well as the potential neurotransmitter profile alterations in drug-naïve benign childhood epilepsy with central-temporal spikes (BECTS) patients.
Methods: Structural magnetic resonance imaging (sMRI) and resting-state functional MRI data from 20 drug-naïve BECTS patients and 33 healthy controls (HCs) were acquired. Parallel independent component analysis (P-ICA) was used to identify covarying components among gray matter volume (GMV) maps and fractional amplitude of low-frequency fluctuations (fALFF) maps.

Objective: The study aimed to determine the prevalence of attention deficit hyperactivity disorder (ADHD) in patients with self-limiting epilepsy with centrotemporal spike wave (SeLECTS), as well as the electroclinical features associated with this comorbid condition and the neurocognitive effects using psychometric tests. Additionally, we analysed the electrophysiological findings and neurocognitive status of patients with ADHD to estimate the prevalence of epilepsy and neurocognitive effects in the ADHD population and evaluate their clinical features.
Method: The study included patients diagnosed with SeLECTS and ADHD who were matched for age and gender.

Article Synopsis
- This study looked at how benign childhood epilepsy with centrotemporal spikes (BECTS) affects brain connections and thinking skills in kids.
- Researchers compared brain networks of 50 kids with BECTS to 69 healthy kids to understand differences in how their brains work.
- They found that kids with BECTS had changes in their brain connections that were linked to lower thinking skills, especially in areas that also affected verbal intelligence.
