ABSTRACT
OBJECTIVES: To investigate the effects of traditional antiepileptic drugs (AEDs) versus newer AEDs on the thyroid hormone profile of children with epilepsy. MATERIALS & METHODS: A total of 80 children with epilepsy were included in this study and were divided into two groups. Group 1 included 40 children with epilepsy on traditional AEDs, and group 2 included 40 children with epilepsy on newer AEDs. Forty healthy children were also included as the control group (group 3). We analyzed the serum levels of free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH). RESULTS: In epileptic children treated with traditional drugs, there was a significant reduction in the serum level of FT4 and a significant increase in TSH concentration, compared to the control group (P<0.001). Conversely, epileptic children treated with newer AEDs showed no significant changes in the serum concentrations of FT3, FT4, and TSH, compared to the control group. CONCLUSION: Traditional AEDs have more significant effects on thyroid hormone profile, compared to newer AEDs.
ABSTRACT
BACKGROUND: The role of nutrients and dietary factors in attention-deficit hyperactivity disorder (ADHD) remains unclear. OBJECTIVES: The primary objective was to evaluate the serum vitamin D level in children with a diagnosis of ADHD. The secondary objective was to detect the effect of vitamin D supplementation on cognitive function in those with vitamin D deficiency. METHODS: A total of 50 children with ADHD and 40 healthy controls were included in the study. We measured the serum level of vitamin D. Patients with vitamin D deficiency were subdivided into 2 groups: one with vitamin D supplementation and the other without vitamin D supplementation. Further assessment and follow-up of children with ADHD was done. The Wisconsin Card Sorting Test, Conners' Parent Rating Scale, and Wechsler Intelligence Scale for Children were performed at baseline and follow-up in all cohorts with an ADHD diagnosis. RESULTS: The diagnosis of vitamin D deficiency was significantly greater in children with ADHD compared with the control group ( P < 0.05). Children with ADHD had significantly ( P = 0.0009) lower values of serum vitamin D (17.23 ± 8.98) than the control group(31.47 ± 14.42). The group receiving vitamin D supplementation demonstrated improvement in cognitive function in the conceptual level, inattention, opposition, hyperactivity, and impulsivity domains. CONCLUSION: Vitamin D supplementation in children with ADHD may improve cognitive function.
