Association between coeliac disease, epilepsy and brain atrophy.
Patients with epilepsy and posterior cerebral calcifications have an increased risk of coeliac disease (CD). The occurrence of this syndrome and the overall risk of CD and epilepsy remain still poorly understood. This study presents the prevalence of CD, brain atrophy, and cerebral calcifications in patients with epilepsy of unknown aetiology. The medical records of 900 consecutive adult patients with epilepsy diagnosis were reviewed. The occurrence of CD in living patients with epilepsy of unknown aetiology (n = 199) was investigated; all patients without previously known CD were asked for serological screening for the disease and the diagnosis was verified with small bowel biopsy. The presence of occipital calcifications and brain atrophy in all available CT scans (n = 130) was evaluated. Five of 199 cases had prior history of CD. The prevalence of definite CD in the patients was 2.5% (5/199), which is significantly higher that the current prevalence of CD in our area (0.27%). Antibody testing and small bowel biopsy in positive cases failed to increase prevalence of CD. Eleven (8.5%) patients had intracerebral calcifications and 3 of them posterior calcifications; all 11 had negative screening results for CD. Four (80%) patients with definite CD had supratentorial brain atrophy compared with 33 (26%) of 125 patients without CD. Prevalence of CD was increased among patients with epilepsy of unknown aetiology, but the combination of CD, epilepsy and intracranial posterior calcifications was rare in Finnish adult epilepsy population.
