 Criteria for diagnosis of abdominal epilepsy includes frequent periodic abdominal symptoms, an abnormal electroencephalogram (EEG) and significant improvement of gastrointestinal symptoms after taking anti-seizure medication.Medical testing for diagnosis can be completed using MRI scans of the brain, CT scans and ultrasounds of the abdomen, endoscopy of the gastrointestinal tract, and blood tests.Like other forms of epilepsy, abdominal epilepsy is treated with anticonvulsant drugs, such as phenytoin.
