“Pseudo Seizures” AND Epilepsy – Yes, You CAN Have BOTH! | October 2, 2018

Some know it as non-epileptic seizures (NES), psychogenic non-epileptic seizures  (PNES), or “pseudo seizures”.

And then there’s epilepsy. Which is what?

What seizures all have in common is that they are usually sudden, short, and cause a change in the person’s awareness of where they are, what they are doing, what they are thinking or what they are feeling.

Some people have more than one type of seizure.

For example, around 15 in every 100 people with non-epileptic seizures (NES) also have epilepsy.

And the numbers are all over the charts in reference to research…

Because non-epileptic seizures often are mistaken for epileptic seizures.

While some patients who have both types can distinguish between the two, others find it difficult to distinguish when they are having non-epileptic seizures.

One study was done to evaluate the frequency of epilepsy in patients with psychogenic non-epileptic seizures (PNES).

The evaluation was carried out during intensive VEEG monitoring in a diagnostic center for epilepsy in a university hospital.

Ninety-eight patients underwent intensive and prolonged video-electroencephalographic (VEEG) monitoring — out of these, a total of 28 patients presented PNES during monitoring.

Researchers concluded that the frequency of epilepsy in patients with PNES is much higher than that of previous studies, and point out the need, at least in some cases, for prolonging the evaluation of patients with PNES who have clinical histories indicating epilepsy.

A Loyola University Medical Center neurologist reported surprising results of a study of patients who experience both epileptic and non-epileptic seizures.

Dr. Diane Thomas and colleagues reviewed 256 patients who had come to the hospital to have their seizures monitored.

Seventy of the patients had documented non-epileptic seizures. Of these, 11 patients (15.7%) also experienced epileptic seizures during their hospital stays.

In previous studies, the percentage of such patients experiencing both types of seizures was less than 10%.

Another study had 22 patients in their sample who were referred on these grounds and, nine (41%) patients showed behaviors associated epilepsy.

Although it’s an admittedly small study, it indicates that, even when the level of suspicion is high for PNES, coexistence of epilepsy may be a significant problem.

In this case, events initially diagnosed as non-epileptic actually prove to be epileptic.

Frontal lobe seizures in particular may not be associated with significant EEG changes and therefore may be misdiagnosed as NES.

That’s where the extended VEEG comes into play.

Unfortunately, since epileptic and non-epileptic seizures can be initially difficult to tell apart, people may at first become worried about the increase in their seizure frequency and this can cause the non-epileptic attacks to spiral more out of control.

So, it becomes a real catch 22.

All this being said, psychogenic symptoms are still not the subject of much clinical research.

Thus, there seems to be a severe disconnect between the frequency of the problem and the amount of attention devoted to it.

  1. Hi Phylis

    It is a catch 22, normally a TC would be caught on a video telemetry EEG but it’s the focal seizures that are difficult to catch, there is no way of definitively proving that a focal seizure is epilepsy or PNES, that’s my situation, annoying, 11 years now and they don’t know if my seizures is epilepsy or PNES or as you say both.
    Just because a seizure doesn’t show up on an EEG, doesn’t mean alot and I’m not surprised that there isn’t more people are misdiagnosed

      • Thanks for the link, all useful tools had most of those, still no diagnosis of the vocals especially when they are simple ones.

        They have started hone video telemetry EEG over here now in some hospitals, exactly the same as a hospital video telemetry EEG but it’s on a laptop that you can take home with you, maybe you have the same in the states ?

      • Yes, Mark. We finally have Ambulatory EEGs that can be done at home at a MUCH lower cost.

        Here’s what I found on the net (all of which I’m sure you’ve done) RE: Focal Seizures

        Depending on your symptoms and your medical history, your doctor may run any number of tests, such as brain imaging scans, blood tests, or a spinal tap to find out the cause of your seizures.

        More…

        Can other health conditions look like focal aware seizures?

        “Yes, some symptoms of focal onset aware (simple partial) seizures are similar to other health conditions.

        Health symptoms or problems, such as nausea or pain from stomach disorders or tingling and numbness from a pinched nerve, can be mistaken for focal seizures.

        Hallucinations (smells, tastes, sounds, visions) can accompany psychiatric illness or the use of certain drugs.

        Some symptoms (such as déja vu) are experienced by almost everyone at some time.

        Temporary numbness or weakness in a limb or the face sometimes occurs from a transient ischemic attack (TIA), which can be a serious warning sign for a future stroke.

        Migraines, with or without a significant headache, can produce visual, tingling, or other symptoms that can be confused with a seizure.

        Your health care provider can help determine whether your symptoms may be focal aware (simple partial) seizures or some other condition.” https://www.epilepsy.com/learn/types-seizures/focal-onset-aware-seizures-aka-simple-partial-seizures

        Sorry I couldn’t give you more helpful input. 😦

  3. Does it really matter what kind of seizures one has?
