Effects of a Gluten-Free Diet on Brain Bioelectrical Activity and Neurological Symptoms in Children with Celiac Disease: A Study Using EEG Assessment.

Celiac disease (CeD), also known as gluten enteropathy, is an immune-mediated inflammatory enteropathy triggered by intolerance to gluten. It presents with a spectrum of symptoms, including both gastrointestinal and extraintestinal manifestations, as well as neurological symptoms. A review of the literature indicates that 10-22% of patients with CeD present with neurological symptoms. The objective of this study is to assess the influence of a gluten-free diet (GFD) on brain bioelectrical activity and neurological symptoms in children with CeD. The study was conducted using a multidisciplinary approach, encompassing a comprehensive array of clinical data gathered alongside laboratory test results, questionnaires, and electroencephalogram (EEG) assessments. The study population included 85 children: 18 newly diagnosed cases of CeD patients (NDC), subsequently reassessed after 6 months on a GFD as a celiac disease on diet (CDD); 27 CeD patients on a GFD for over 12 months (CDD2); and 40 healthy individuals in the comparison group (CG). It was observed that over half of the NDC group exhibited neurological symptoms, particularly headaches. Following a six-month period on a GFD, there was a notable reduction in symptom severity. In comparison to the CG, the NDC patient group exhibited a higher prevalence of abnormalities in EEG recordings ( = 0.032), including focal sharp waves or slow waves. The results demonstrate that a GFD has a positive impact on the neurological condition of children with CeD. The clinical improvements correspond with EEG normalization, which supports the hypothesis that dietary intervention plays a role in mitigating CeD-associated neurological dysfunction.
