Background: Celiac disease is an immune-mediated disorder known to manifest not only with gastrointestinal symptoms but also with a wide range of extraintestinal features, including neuropsychiatric conditions.
Case presentation: We describe the case of a 4-year-old girl who presented with isolated stuttering. Serologic tests revealed elevated anti-tissue transglutaminase antibodies, and a diagnosis of celiac disease was confirmed by duodenal biopsy. A strict gluten-free diet was initiated. The patient's speech disorder began to improve by the sixth month of treatment and resolved completely by the twelfth month of dietary adherence.
Conclusion: This case highlights the importance of considering celiac disease in the differential diagnosis of speech disorders in pediatric patients, especially when no other underlying cause is identified.
