Non-Epileptic Seizures

Seizures are when a person temporarily loses control of their body. They can be divided into two types based on their cause. Epileptic seizures are caused by abnormal brain activity. Non-epileptic seizures are caused by a problem other than abnormal brain activity.

Symptoms

The symptoms for non-epileptic and epileptic seizures are similar. These include:

  • Falling to the ground
  • Shaking or jerking movements
  • Rhythmic twitching
  • Repetitive movements
  • Losing consciousness
  • Feeling confused or mixed up once the seizure is over
  • Stiffening of the entire body or different parts of the body
  • Uncontrolled shouting out or making other sounds
  • Biting the tongue
  • Uncontrolled emptying of the bladder or bowels
  • Staring
  • Feeling that the senses have stopped working properly
  • Tingling sensations
  • Dizziness
  • Changing emotions

Causes

Non-epileptic seizures are divided into two types based on their cause:

  • Those with a physical cause
  • Those with a psychological cause

Some physical causes of non-epileptic seizures include:

  • Some heart problems
  • A problem with blood sugars such as diabetes
  • Narcolepsy (a sleep problem where a person suddenly falls asleep during the day)
  • Tourette’s syndrome (a condition where a person has uncontrollable tics)
  • High fever
  • Severe infection
  • Electrolyte imbalance
  • Withdrawal from drugs or alcohol

Some psychological causes of non-epileptic seizures include:

  • A major or life-threatening accident (for example, a road traffic accident)
  • Physical, mental, or sexual abuse
  • Severe mental or emotional pain (such as the death of a loved one)
  • Being bullied
  • Seeing or experiencing a traumatic event (such as during war)

Risk Factors

Non-epileptic seizures can happen to anyone at any age. However, they are more common in:

  • Females
  • Young adults
  • People who have other mental illness such as anxiety or depression
  • People who have experienced traumatic events

Diagnosis

The gold standard for diagnosis is called an electroencephalogram (EEG). This is a test where electrodes are stuck to the patient’s scalp and then connected to a device. The device records the patient’s brain activity. When the person has a seizure, the device shows if there is abnormal brain activity. An EEG is only done by a specialist.

Sometimes, the EEG alone is not enough to make the diagnosis. The doctor may then ask friends or family to take a video of the patient’s seizures.

In hard to diagnose cases, the doctor may ask the patient to stay overnight at a special seizure unit. These are usually in a hospital. The stay may last up to two weeks. During this time, the patient will be monitored by EEG and by video. This helps the doctor confirm the diagnosis.

Once non-epileptic seizures are diagnosed, the doctor will request other tests to find the cause. They may request:

  • Blood tests
  • ECG – a heart tracing
  • Echocardiogram – a heart test which watches the heart as it works
  • Imaging of the brain with a CT scan or MRI
  • Specialized psychological testing

Complications

The most common complication is physical injury during the seizure itself. However, seizures can affect all aspects of a person’s life. By law, uncontrolled seizures can restrict a person’s ability to drive, operate heavy machinery, or do certain jobs.

Treatment

Treatment for non-epileptic seizures depends on the cause. The patient will be referred to appropriate specialists as needed. This can include a qualified mental health professional if the cause is thought to be psychological.

Traditional anti-epileptic medications do not work for non-epileptic seizures. However, medications for depression or anxiety can be helpful for some people.
