Pure tone audiometry was performed for all participants using the Inventis piano dual-channel audiometer. The total scores were compared with the normative data, and those who passed the test were only considered for the study. Each correct response was given one point, and the incorrect response received a zero mark. The participants had to copy the shapes on an A4 size paper. In this test, all participants were presented with different geometrical shapes, with the complexity of the shapes progressing from easy to difficult. The intelligence was screened using the extension and validated version of the Gesell drawing test (a screening IQ test). Intelligence tests and hearing assessments were performed before the memory tests. Age- and gender-matched typically developing children (TDC) without any otological or neurological illnesses were recruited from the pediatric OPD as controls. However, MRI was not done for the participants. All the participants had undergone sleep and awake EEGs. Children with clinical characteristics of attention deficit hyperactivity disorder, autism, etc., were excluded from the study. From the eligible cohort, we included children with typical clinical history and EEG findings of SECTS syndrome. After the ethics committee approval, the participants were screened and recruited from the epilepsy clinic, Neurology Department, using a consecutive sampling technique. Therefore, the present study aimed to measure the working memory abilities in children with SECTS. The studies documenting the memory abilities in children with SECTS are inconclusive and vary from no memory deficit to severe impairment. Most studies recommended using working memory tests when evaluating the individual's listening abilities. Working memory capacity is strongly linked to the auditory perception when the signal is distorted and contributes less when the acoustic signal is not distorted. The perception of spoken language requires a listener to extract, store, and integrate rapidly varying auditory stimuli. Working memory deals with the processing and storage when performing a task. Over the last decades, more attention has been given to studying the influence of working memory in processing verbal messages, especially in adverse listening situations. Recent studies reported that children with SECTS often exhibit difficulty processing verbal messages even though their peripheral hearing sensitivity was normal. Despite the improvements in the frequency of seizures and the remission of seizures before puberty, many children with SECTS present with disturbances in neuropsychological evaluations. The typical electroencephalography (EEG) findings include high voltage sharp centrotemporal spikes preceded by slow waves triggered by sleep and show a tendency to extend or change from one side to the other. It usually begins at the age of 3 to 13 years and disappears after puberty. Self-limited epilepsy with centrotemporal spikes (SECTS) is a common focal epilepsy syndrome in childhood. ![]() Self-limited epilepsy with centrotemporal spikes. The association between poor working memory and reported speech recognition impairment in children with SECTS needs to be studied. Factors such as the age of onset of seizures, duration of seizures, frequency of seizures and spike load did not influence the working memory.Ĭonclusion The children with SECTS demonstrated impairment in working memory abilities compared with normal children. Statistical Analysis and Results The working memory of children with SECTS, measured with backward digit span, was significantly poor compared with the TDC ( p < 0.001). The Digit span backward test was used for measuring working memory abilities. Materials and Methods Twenty-two children with SECTS and 22 typically developing children participated in the study. This study aimed to measure the working memory and its associated factors in children with self-limited epilepsy with centrotemporal spikes (SECTS) and compare it with the typically developing children (TDC) without epilepsy. Objectives Working memory abilities are essential in the perception of acoustic signals, especially in the presence of noise.
