Dissociative seizures

Is this page for me?

You may find this information useful if you:

  • Have just been diagnosed with dissociative seizures
  • Have been told for years you have epilepsy and you’re now being told the diagnosis was wrong. And that you have dissociative seizures instead
  • Have been told that you have both epilepsy and dissociative seizures
  • Are waiting for a diagnosis and wondering whether you may have dissociative seizures
  • Are wanting to understand and support someone who has been diagnosed with dissociative seizures

Other names for dissociative seizures

Many different names are used for dissociative seizures. We have chosen the name used in the International Classification of Diseases. Other commonly used names are non-epileptic attack disorder or non-epileptic seizures. However some people are unhappy to have a diagnosis that is ‘not’ something. Other names that are used for the same condition are:

  • Psychogenic non-epileptic seizures
  • Psychogenic seizures
  • Functional seizures

In the past dissociative seizures were also often called “pseudoseizures”. This term is now discouraged because it wrongly implies that these seizures are consciously produced to look like epileptic seizures.

Whichever name you have come across, this information is for you.

Getting a diagnosis for dissociative seizures

Dissociative seizures are often mistaken for epilepsy. They can be difficult to diagnose. In fact, it can take several years after someone starts having seizures for them to get an accurate diagnosis of dissociative seizures. Even experienced doctors can find diagnosing dissociative seizures a challenge.

It’s very important to get the right diagnosis. This is because if you’re wrongly diagnosed with epilepsy instead of dissociative seizures, the doctor will probably prescribe you epilepsy medicines. These can have side-effects and will not control your dissociative seizures. Being on these medicines also means that the true cause of your seizures may never be investigated or treated.

If you have been prescribed epilepsy medicine and you don’t have good seizure control you could ask to be referred to a specialist epilepsy centre for assessment. You would need to ask either your neurologist or your family doctor. You could have a type of epilepsy that doesn’t respond well to epilepsy medicines. This is sometimes called intractable or refractory epilepsy. Or you could have dissociative seizures and that’s the reason why you aren’t responding to epilepsy medicines.

Some people have both epilepsy and dissociative seizures. Mostly dissociative seizures start a while after the epileptic ones (and possibly once the epileptic ones have stopped). Occasionally people can have both types of seizures at the same time. If you think you may have both types of seizures you could talk to your consultant.

How can you tell the difference between epilepsy and dissociative seizures?

It can sometimes be difficult to tell the difference between an epileptic seizure and a dissociative seizure. If you are not an expert in this field you may not be able to tell by looking whether someone is having an epileptic or a dissociative seizure.

One of the ways in which a professional will tell the difference between dissociative seizures and epilepsy, is from an electroencephalogram (EEG). This picks up and records the electrical activity in the brain. If someone is having an epileptic seizure, an EEG will usually show abnormal electrical activity. If someone is having a dissociative seizure, an EEG will not show abnormal electrical activity.

The doctor may also suggest using video-telemetry. This involves you wearing EEG equipment for a few days, and being observed by a video camera linked to the EEG machine. This makes it possible for any seizures you have to be recorded on video and EEG at the same time.

Epilepsy Action has more information about video-telemetry

What makes dissociative seizures happen?

Dissociative seizures happen for psychological reasons rather than physical ones. Often dissociative seizures are how the brain reacts to thoughts or feelings related to present and past experiences. This is different from epilepsy. Epileptic seizures happen because of abnormal electrical activity in the brain.

I have just been told I have dissociative seizures. What do I do now?

It can be really tough to be told you have dissociative seizures. This is especially true if you’ve spent years thinking you have epilepsy, and you’ve been trying to adapt to that. It’s quite usual for it to take time to understand the new diagnosis. Also, if the diagnosis of dissociative seizures is not explained well, it can sound like the doctor is saying you don’t have a real health condition, or that you are ‘putting it on.’ This is not true. Dissociative seizures are a real medical condition. And the dissociative seizures you experience can be just as disruptive and unsettling as epileptic seizures. You’ll need the support of friends, family and medical people during this time of adjustment. If you have been diagnosed with dissociative seizures you could ask the consultant for a referral to a talking therapy. In some parts of the country this could be a psychologist.

What is the treatment for dissociative seizures?

If you have dissociative seizures, epilepsy medicine won’t work for you. But don’t stop taking the medicine suddenly because this may be dangerous for you. Your doctor will tell you the right speed to do this at. Often just getting a correct diagnosis and understanding a bit more about your seizures can mean that they start to happen less often.

It is important to remember:
“You didn’t bring the attacks on, but you can help yourself to get better.”

If seizures don’t stop once you have your diagnosis, a number of more specialist treatments may be offered to you:

  • Cognitive behaviour therapy (CBT)
  • Counselling
  • Psychotherapy
  • Anti-depressants

The aim of CBT is to help you explore and change how you think about your life, and free yourself from unhelpful patterns of behaviour. You set goals with your therapist and may carry out tasks between sessions. A course usually involves around 12 to 20 sessions.

The NHS website has information on counselling, CBT and psychotherapy

You may feel you’ve been dismissed with no offer of treatment. But something you could do without the help of a doctor is look at the NHS website. It describes the various types of therapies you may want to think about. And the IAPT service (Improving Access to Psychological Therapies) links you to the resources in your area. There are likely to be waiting lists for any of these services, so the sooner you make contact with them the better.

Whichever therapy you choose it will ideally be with someone who also understands about dissociative seizures. Your neurologist or epilepsy nurse may be able to recommend someone. If this all feels a bit overwhelming your GP may be able to help.

Some common causes of dissociative seizures are stress, anxiety and post-traumatic stress disorder (PTSD). Anything that helps with an understanding of how these affect the body may help with managing your seizures. There are many ways to help manage your stress and anxiety levels. These include activities such as mindfulness and yoga.

The NHS website has information on stress.

Dealing with stress levels and trying to get the right amount of sleep are 2 particularly important things to consider when managing your seizures

For more tips on how to manage your dissociative seizures see links to the websites at the bottom of the page.

Evelina Children’s Hospital has made a film about dissociative seizures (they call it NEAD in the film). The film talks about the service at Evelina. Services at other hospitals may be different.

What first aid do I need?

This is what someone needs to do if they see you having a seizure.

Do

  • Cushion your head
  • Move any harmful objects away from you
  • Be calm and reassuring
  • Call an ambulance if they don’t know if you have epilepsy or dissociative seizures. (This may not be necessary if they have experience of looking after you during your seizures)

Don’t

  • Call an ambulance unless you are injured or they don’t know about your condition
  • Restrain you in any way
  • Try to give you any medicine

 Dissociative seizures are not dangerous and do not cause damage to the brain. The only reason someone would need to call an ambulance is if you injured yourself. Dissociative seizures often go on longer than epileptic seizures.

Sorry I will try to be brief as possible. I wonder if I have epilepsy or its mimic dissociative condition? Please advise!
My GP hasnt told me I suffer from epilepsy, its my query, and I just read on your website about the mental dissociative state that mimics epilepsy.
Episodes occur pretty precisely typically last week of each month for 2 or 3 days, from 3 to 10 times per day. I dont fall over or lose consciousness, but cant speak to any companions and feel as if dreaming - as if i've returned to . . . previous episode.?
Its hugely scary and unpleasant, Usually close my eyes. Then after one or two minutes the feeling recedes. I open eyes to find Im breathing very hard and heart racing. I recover equilibrium within minutes and that's it until the next time. These episodes have been occurring since summer 2015 so began months after an aortic valve replacement in August 2014. The op. was declared a success but I never recovered previous fitness and strength, with shaky left hand (right hand seems ok)
I am 79 but two years ago used to garden, paint, sculpt, cook, shop etc. - now all too hard. The dream-seizures are a wretched addition, but my GP thinks - "well, she is old. . . "
Yet the century is bedizened with active creative 80 year olds. Please advise me what to do or try?!

Hi Maril

That must be disturbing to have these episodes affect your life so consistently. You don’t mention whether you have seen a neurologist. If you haven’t you might want to ask your GP to refer you to one. Then you should get proper tests to check out what is happening for you. The specific description of these episodes would be really useful for the consultant.

I hope you get some answers soon.

My daughter was diagnosed with epilepsy aged 9. She is 30 now . They have always said there was no eeg readings but came to the conclusion through video that it was a rare form of epilepsy .
3 years ago she had tests to see if surgery was an option and had the radio active dye inserted while having seizure then straight into scanner ... and nothing showed !
We have been reading up on nead and wonder if this could be the reason no electrical brain activity has ever been recorded .
Would really appreciate an opinion on this .
Thank you

Hi Christina

It is quite usual for someone with epilepsy to have a normal EEG and MRI. This is partly because an EEG will usually only show epileptic activity if someone is having a seizure during the scan: https://www.epilepsy.org.uk/info/diagnosis/eeg-electroencephalogram

Did the incident you are talking about involve an MRI or an EEG?

If it was an EEG then there is every possibility it was a dissociative seizure: https://www.epilepsy.org.uk/info/diagnosis/dissociative-seizures-non-epileptic-attack-disorder-nead

But I’m also wondering what happened as a result of the surgery investigative tests. And what has happened in the 3 years since then? Is your daughter still being treated for epilepsy?

Sorry to be asking more questions, but I am hoping I can be of a little more help if I’m clearer about your daughter’s situation.

If you would prefer you could contact us again by email or the Epilepsy Helpline freephone 0808 800 5050.

About two years ago I began to have episodes where I would fall to the floor and fit. It would look like a tonic-clonic seizure, only I would be conscious the entire time. I have talked and answered questions during these episodes before, although my eyes are closed and I have no other control over my body. They usually last bewteen 2-6 minutes and leave me feeling extremily tired. All doctors are quick to tell me is that it's not epilepsy, because I am conscious. I feel like most doctors assume I am making it all up, however I have now had my 25th attack and I just want some advice so I can stop feeling so helpless about the situation. I wonder if others have had similar issues to me? I'm not looking into NEAD but I'm really feeling alone aabout this.

Hi Lindsay, I'm terribly sorry to hear you don't have a diagnosis, I can understand the frustration and sadness that it brings. Your symptoms sound exactly like mine, I have been taking Lamictal for around 15 years, it has been very successful, but I am now dealing with liver damage (which must be from the medication) as I might have 1 alcoholic drink per 6 months. With the same symptoms as you I was diagnosed with temporal lobe epilepsy. Hopefully you can find a doctor that can help, don't give up. Hugs.

Hi, I will be 53 years old in March this year and in March 2018 I started with small seizures during my sleep and first thing in the morning. But in November I started having seizures through the day. I have had an EEG and mri. The consultant has diagnosed Non Epeleptic Seizures and has referred me to see a phsycholist. I am at my wits end as I am having Seizures anything from 2 to 6 a day every day lasts anything from 40 mins to 2 hours with a short break and at the moment I can not be left on my own. I feel like my life has been taken up with these. I would appreciate it if you have any advice.
Regards, kay

Hi Kay

It can be really difficult to come to terms with a diagnosis of non-epileptic seizures. Sometimes it does start to feel a little easier when you have a clear diagnosis.

Often these seizures are triggered by a level of stress. So you might find our range of information on wellbeing useful. It’s great that you are being referred to a psychologist. But it might also be worth asking your family doctor if there is anything they could suggest to help you with stress management, especially while you’re waiting for the referral to come through.

I hope this information is useful and that things improve for you soon.
