A note about terminology
This web site deals mainly with Psychogenic Nonepileptic Seizures, which is one of two main types of Nonepileptic Seizures. The term "Nonepileptic Seizures" describes the "condition" while the term used before it describes the "type" of Nonepileptic Seizure. The other type is referred to as Physiologic Nonepileptic Seizures.
Another name that has been used in the past for NES is Pseudoseizures, but this term is inaccurate and has generally been abandoned. It implies that the seizures are faked. Another term sometimes used is Non-epileptic Attack Disorder (NEAD).
For the purposes of this web site we will be using the term Nonepileptic Seizures (NES) in speaking about Psychogenic Nonepileptic Seizures (PNES). This is due to it being the most common term currently used.
What are Nonepileptic Seizures?
Nonepileptic Seizures are epileptic-like seizures that are involuntary and not under the control of the person having them. It is very important to understand that these seizures are not "faked" and you are not "crazy". They are different from epileptic seizures in that they do not result from abnormal electrical discharges in the brain. Nonepileptic Seizures, however, can be just as debilitating as epileptic seizures. Nonepileptic seizures (NES) can look like any type of epileptic seizure including generalized tonic-clonic seizures, absence seizure, complex partial seizures, etc. And it should be noted that true epileptic seizures sometimes occur in patients with Nonepileptic Seizures.
It has been estimated that anywhere from 150,000 to as many as half a million people have NES. This makes NES as common as multiple sclerosis. About 30% of patients seen at Epilepsy Centers are found to have NES.
What Causes Nonepileptic Seizures?
Nonepileptic seizures generally fall under two categories: psychogenic and physiologic. Physiologic NES can be caused by physical problems such as cardiac arrhythmias and hypoglycemia. Causes of Psychogenic Nonepileptic Seizures include events such as trauma experienced in childhood including sexual abuse, physical abuse, and emotional abuse. Even the stress caused by the death of a loved one and divorce can be causes. Some studies have shown that 75% or more of NES sufferers are women and many have a history of sexual, physical or emotional abuse in childhood. Often times patients with NES also have other psychological disorders like Post Traumatic Stress Disorder (PTSD), depression, anxiety, conversion disorder and dissociative disorders.
How are Nonepileptic Seizures diagnosed?
NES are very difficult to diagnose and patients are often misdiagnosed as having epilepsy. This causes many to go incorrectly diagnosed for an average of 7 to 9 years before the correct diagnosis is made. This causes many sufferers to take anti-epileptic drugs (AED's) that are often ineffective, unnecessary and costly. Correct diagnosis is important for these reasons. Diagnosis of NES is made using video-electroencephalography (VEEG) as well as careful examinations of the patient's history. The absence of EEG abnormalities while simultaneously observing the patients seizure is considered a key factor in a diagnosis of NES.
How are Nonepileptic Seizures treated?
Treatment of psychogenic NES is best received from someone experienced in psychological treatments such as a psychiatrist or psychologist. Because NES is not a physical illness it makes sense to seek treatment from a psychiatrist or psychologist. Again, this doesn't mean you are "crazy" and in our opinion this is a courageous decision and is a sign of your strength. With treatment patients can learn to eliminate the need for this once necessary defense mechanism. Often time's the treatment will include discontinuation of anti-epileptic drugs (AED's), which are usually not effective.
