Celiac disease and epilepsy in pediatric patients

Among 783 patients referred to our institute with different types of seizures as presenting symptom, systematic evaluation of antigliadin and antiendomysial antibodies in the serum has identified nine in whom jejunal biopsy has subsequently confirmed the diagnosis of celiac disease (CD). In three of them brain imaging showed the presence of calcified areas in the occipital region. They had complex partial seizures (CPS), associated in two with transient episodes of blindness. In another patient with CPS and generalized tonic-clonic seizures (GTCS) progressive multifocal cerebral calcifications were noted. In the other six patients with CPS and/or GTCS cerebral calcifications were absent. Symptoms of CD in all these cases were either not previously taken into account, or they were very mild or completely absent. In a group of 36 patients with clinically manifest CD, regular follow-up, and good compliance with the dietary regimen, no clinical seizures were reported. The pathogenetic mechanism and the relationship between epilepsy and an early diagnosis and treatment of celiac disease are discussed.
