Objectives: Crohn's Disease (CD) is a chronic systemic inflammatory disease associated with various extraintestinal manifestations, including seizure as a neurological finding. In this study, the prevalence of seizure and electroencephalographic abnormalities in patients with CD was investigated.
Materials and methods: This study involved 41 patients with CD (female/male: 25/16) and 39 subjects in the control group (female/male: 25/14). Patients in the CD group were diagnosed and monitored according to the European Crohn's and Colitis Organization diagnostic criteria. The control group was composed of healthy subjects with similar age and sex as the CD group. Seizures were classified according to the criteria of the International League Against Epilepsy. Electroencephalography (EEG) was performed for all patients with CD and for healthy subjects. Seizure prevalence and EEG findings were also compared.
Results: One patient in the CD group had history of seizures. EEG abnormality was significantly higher in the CD group (16/41, 39%) ( P = .001). The most common EEG abnormality was intermittent generalized slow wave abnormality in theta frequency.
Discussion: Our study indicated that CD was associated with EEG abnormalities rather than seizure. The results also indicated that EEG was a potential indicator for detecting subclinical neurological abnormalities in CD.
