ABSTRACT
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. 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 SeLECTS group also underwent the Bender Visual-Motor Gestalt Test.RESULTS:
No significant relationship was found between the SeLECTS 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 SCWT completion time was significantly longer in the SeLECT + ADHD group than in the isolated SeLECTS 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.Palavras-chave
