    Levels of Melatonin in Continuous Spikes and Waves During Sleep
    (SAGE Publications Inc., 2019) Ayça S.; Aksoy H.U.; Taştan İ.; Polat M.
    Levels of melatonin have been reported before in children with epilepsy, but such has not been reported to date in those with continuous spikes and waves during sleep. The aim of the present study was to assess serum melatonin levels and melatonin circadian rhythm in patients with continuous spikes and waves during sleep and epilepsy. Serum melatonin was measured in 39 children stratified into 3 groups. Group 1 included 15 patients with continuous spikes and waves during sleep, group 2 included 12 epilepsy patients, and group 3 included 12 controls, respectively. Blood samples were taken from all participants at 1:00 am and 9:00 am and melatonin levels were measured using a quantitative enzyme-linked immunosorbent assay test. The 9:00 am melatonin levels of group 1 were significantly decreased and pair groups were compared. The P a value (representing a comparison between groups 1 and 2) was.002, the P b value (representing a comparison between groups 1 and 3) was.001, and the P c value (representing a comparison between groups 2 and 3) was.86. These findings suggest that the 9:00 am melatonin levels were significantly decreased in the comparison of groups 2 and 3. Further detailed research is necessary to determine the factors leading to the rapid decline of morning melatonin levels of children with continuous spikes and waves during sleep. © The Author(s) 2019.

    Neurocognitive effects and electrophysiological findings in ADHD and self-limiting centrotemporal spike wave epilepsy (SeLECTS) − A prospective tertiary care study
    (Academic Press Inc., 2024) Orak S.A.; Bilaç Ö.; Polat M.; Sobay N.S.; Yalçin A.H.; Korkmaz R.; Kubur Ç.Ç.; Atasever A.K.; Yilmaz C.; Özyurt B.C.
    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 SeLECT and ADHD who were matched for age and gender. Electrophysiological tests, psychometric tests, demographic and clinical characteristics of SeLECTS patients aged 7–13 years and ADHD patients of similar age were analysed. The study examined electrophysiological and psychometric tests, as well as demographic and clinical characteristics. Both groups underwent testing using the Wechsler Intelligence Scale for Children (WISC-R), Stroop Colour and Word Test (SCWT), and EEG (Electroencephalogram). The SeLECT group also underwent the Bender Visual-Motor Gestalt Test. Rsults: No significant relationship was found between the SeLECT and ADHD groups in terms of age and gender. The rate of epileptiform discharge in EEG findings without a diagnosis of epilepsy was 5.6 % (n = 2) in the ADHD group. The rate of ADHD in the SeLECTS group was 28 % (n = 11). Although all subsections of the WISCR test were higher in the ADHD patient group than in the SeLECTS patient group, only verbal IQ and total IQ showed a significant difference. No significant differences were found between the completion times, error rates, and correction averages of the SCWT sections in both groups. There was no significant correlation found between the performance IQ, verbal IQ, and total intelligence scores in either the isolated SeLECTS patient group or the SeLECTS + ADHD patient group (p > 0.05). However, it is worth noting that verbal IQ was below normal in both groups and slightly lower in the SeLECT + ADHD group. Additionally, the mean SeWT completion time was significantly longer in the SeLECT + ADHD group than in the isolated SeLECT group. However, no significant difference was found in the Bender Gestalt Visual Motor Perception Test. In the psychometric analyses comparing the isolated SeLECTS, SeLECT + ADHD, and ADHD patient groups, the SCWT completion times were significantly longer in the SeLECT + ADHD group than in the other two groups. The verbal IQ score was significantly higher in the ADHD group than in the other two groups. Conclusion: In conclusion, although SeLECTS is commonly considered a benign form of epilepsy, our study found a high rate of comorbidity with ADHD. This condition has a negative impact on verbal intelligence and sustained attention, highlighting the importance of a complete neuropsychological evaluation at the stage of epilepsy diagnosis. It is crucial not to overlook the possibility of an ADHD diagnosis. © 2024
