Abdominal Epilepsy in Children and Adults

Font Size

Abdominal epilepsy is an exceptionally rare syndrome of epilepsy that's more likely to occur in children. With abdominal epilepsy, seizure activity causes abdominal symptoms. For example, it may cause pain and nausea. Anticonvulsant medications can improve the symptoms.

Abdominal epilepsy is so uncommon that some experts question whether it exists. Abdominal pain is common in people with epilepsy as well as without. So it could be that the abdominal pain is only coincidental, not caused by seizures.

What Are the Symptoms of Abdominal Epilepsy?

Little is known about abdominal epilepsy. There have only been 36 cases reported in medical journals in the last forty years.

With abdominal epilepsy, it's thought that seizures occur that primarily affect the digestive system. Gastrointestinal symptoms are the result. Those symptoms include:

  • abdominal pain, usually sharp or cramping and lasting seconds to minutes
  • nausea and/or vomiting
  • fatigue, lethargy, or sleep following seizures
  • altered level of consciousness, such as confusion or unresponsiveness
  • convulsive seizures known as generalized tonic-clonic seizures

People with reported abdominal epilepsy have different patterns of symptoms. Further, symptoms may vary in the same person from one time to the next. For example, a person might have convulsive seizures and abdominal pain during one episode. Then the person may only have abdominal pain during another seizure.

What Causes Abdominal Epilepsy?

No one knows what causes abdominal epilepsy. Because the condition is so rare, no high-quality studies exist. There have been too few reported cases to identify risk factors, genetic factors, or other potential causes.

How Is Abdominal Epilepsy Diagnosed?

Diagnosing abdominal epilepsy can involve a chicken-or-the-egg debate. Seizures in epilepsy are sometimes preceded by patterns of symptoms. These patterns of symptoms are called auras. Just before a seizure, some people with epilepsy might smell something that's not there. Others might see flashing lights.

Auras with abdominal symptoms are common in epilepsy. You can call it a gut feeling. Nausea, pain, flatulence, or hunger can herald a seizure. But are the abdominal symptoms ever evidence of seizures in their own right?

Some experts think the diagnosis of abdominal epilepsy should be made when abdominal symptoms are the main manifestation of seizure activity.
