Nonepileptic Seizures


What is a nonepileptic seizure (NES)?

A NES is a short period of symptoms that change how you move, think, or feel. A NES looks like an epileptic seizure, but there are no electrical changes in the brain. A NES is caused by the body's reaction to severe mental stress. Common triggers are depression, hallucinations, mild head injuries, and sexual or physical abuse. A NES is a serious condition. Early diagnosis and treatment are needed to prevent further problems.

What are the signs and symptoms of a NES?

  • Twitching in your arms or legs that lasts more than 2 minutes
  • Crying, screaming, or weeping
  • Head, neck, and spine bent backwards
  • Side to side head movements
  • Strong or powerful pushing of the hips
  • Thrashing or violent movements, such as striking at walls or breaking pieces of furniture
  • Tongue biting

How is a NES diagnosed?

  • Blood tests may show the cause of your NES.
  • A CT or MRI may show the cause of your NES. You may be given contrast liquid to help your brain, blood vessels, and skull show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
  • An EEG , or electroencephalogram, may show brain function. Small pads or metal discs are put on your head. Each has a wire that is hooked to a machine. This machine prints a paper tracing of brain wave activity from different parts of your brain. A video-electroencephalogram records behavior and the EEG at the same time. Changes in behavior are related to changes in the EEG.

How is a NES treated?

  • Anxiety medicine helps keep you calm and relaxed.
  • Antidepressants help decrease the symptoms of depression.
  • Cognitive behavioral therapy helps you learn to face a feared object or situation slowly and carefully. You will also learn to control the mental and physical reactions of fear.
  • Psychotherapy is therapy that includes your family or people who are close to you.
