Abdominal epilepsy.

Abdominal epilepsy is an uncommon syndrome in which gastrointestinal complaints, most commonly abdominal pain, result from seizure activity. It is characterized by (1) otherwise unexplained, paroxysmal gastrointestinal complaints, (2) symptoms of a central nervous system disturbance, (3) an abnormal electroencephalogram with findings specific for a seizure disorder, and (4) improvement with anticonvulsant medication. We review the history of the syndrome and analyze all 36 cases reported in the English literature from the last 34 years. The most common gastrointestinal symptoms include abdominal pain, nausea and vomiting, while the most common neurological symptoms include lethargy and confusion. After exclusion of more common etiologies for the presenting complaints, workup should proceed with an electroencephalogram. Where the diagnosis is seriously considered, neurological consultation should be considered. Treatment typically begins with anticonvulsant medication, and resolution of symptoms with therapy helps to confirm the diagnosis.
