# Risk factors of electrical status epilepticus during sleep in children with benign childhood epilepsy with centro-temporal spikes

## TL;DR

The study identifies risk factors for electrical status epilepticus during sleep in children with a specific type of childhood epilepsy.

## Contribution

The study identifies specific risk factors for ESES occurrence in BECT children through clinical comparison and statistical analysis.

## Key findings

- Younger age of first seizure is a risk factor for ESES in BECT children.
- Higher seizure frequency before treatment is associated with ESES occurrence.
- Seizures occurring after treatment are linked to ESES development.

## Abstract

To explore risk factors of electrical status epilepticus during sleep in children with benign childhood epilepsy with centro-temporal spikes (BECT).

This is a clinical comparative study. The subjects of study were 67 children with BECT from the Outpatient Department of Pediatric Neurology in Xingtai People’s Hospital from January 2019 to January 2022. According to the occurrence of ESES, the enrolled children were divided into control group which included BECT children without ESES and the observation group which included BECT children with ESES. Compared differences of the two groups in the age of first seizure, the frequency of seizures before treatment, the classification of treatment drugs, cranial MRI, and discharge side of electroencephalogram (EEG).

There was no statistical difference between the two groups in the frequency of seizures before treatment, the classification of treatment drugs, cranial MRI, and the distribution of EEG discharges in the left and right cerebral areas(P>0.05). Statistical differences were observed in the age of the first seizure, whether the seizures occurred after treatment, and EEG discharges in unilateral/bilateral cerebral areas (P<0.05). Furthermore, the collinearity test and Logistic regression analysis showed that the age of the first seizure, the frequency of seizures before treatment, and whether the seizures occurred after treatment were independent risk factors for the occurrence of ESES in BECT (P<0.05).

Clinically, the occurrence of ESES in children with BECT may be related to the younger age of the first seizure, higher frequency of seizures before treatment, and the occurrence of seizures after treatment.
