Prevalence of Seizures in Children Diagnosed With Neurodevelopmental Disorders.

Abstract

Introduction Neurodevelopmental disorders (NDDs) typically emerge in early childhood and have a profound impact on the development of the nervous system, leading to various neurological challenges in cognition, communication, social interaction, motor skills, and behavior. These disorders arise from disruptions in brain development mechanisms. NDDs include conditions such as cerebral palsy (CP), global developmental delay (GDD), intellectual disability (ID), attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorder (ASD), with ADHD and ASD being the most prevalent. However, there is a lack of comprehensive research on the causes of NDDs in children receiving care at tertiary hospitals in Saudi Arabia. Therefore, in this study, we aimto investigate the characteristics of patients with NDDs and explore the association between NDDs and seizures. It also focuses on identifying specific risk factors that may influence the relationship between NDDs and seizures. Methods We conducted a retrospective cross-sectional study at the pediatric neurology and developmental assessment clinic of King Abdulaziz University Hospital in Jeddah, Saudi Arabia. The study involved a review of electronic medical records from January 2021 to May 2023 for 200 pediatric patients who attended the clinic for NDD and seizures. Descriptive statistics summarized the data, using frequencies and percentages for categorical variables, and mean ± standard deviation for quantitative variables. The chi-square test identified differences between qualitative variables, with a significance threshold of p < 0.05. Results The study sample comprised 200 children ranging in age from one month to 14 years, with the majority of patients being from Jeddah city. Participants were categorized into four age groups: 17.0% (n=34) were aged between one month and three years, 18.5% (n=37) were aged between three and six years, 55.0% (n=110) were aged between six and 12 years old, and 9.5% (n=19) were aged between 12 and 14 years. The NDD subtypes identified were ASD 9.5%, ADHD 16.0%, CP 8.5%, GDD 30.5%, ID 5.5%, and 30% had multiple types of NDD. Generalized tonic-clonic seizures were the most common type observed. Conclusion Children with NDDs exhibit a high prevalence of seizures, with the age of the patient and consanguinity emerging as significant influencing factors in this correlation. Among the key findings is an emphasis on the importance of early detection and intervention for children with NDDs at higher risk of developing seizures. Overall, the study sheds light on the characteristics of NDD patients and their association with seizures, contributing to a better understanding of the complex relationship between NDDs and seizure occurrence. It also emphasizes the need for comprehensive assessment and management strategies that consider seizures in children with NDDs.
