Dissociation is a type of mental illness which impacts how you perceive yourself and the world around you. Many people will experience dissociation at some point in their lives.
Lots of different things can cause you to dissociate. For example, you might dissociate when you are very stressed or after something traumatic has happened to you.
You might also have symptoms of dissociation as part of another mental illness. Like an anxiety disorder.What are the symptoms of dissociation?
Some of the symptoms of dissociation include the following.- You may forget about certain time periods, events and personal information.
- Feeling disconnected from your own body.
- Feeling disconnected from the world around you.
- You might not have a sense of who you are.
- You may have multiple identities.
- You may feel little or no physical pain.
You might have these symptoms for as long as the event that triggered them or for a short time afterwards. This is called an episode.
For some people these symptoms can last for much longer.
If you have a dissociative disorder, you might experience these symptoms for long episodes or even constantly.
-
There are different types of dissociative disorder. There is more information on each of these below.
- It is important to remember that you could have the symptoms of dissociation without having a dissociative disorder.
- There can be disagreement among professionals about dissociative disorders.
What is dissociative amnesia?
If you have dissociative amnesia, you might not remember things that have happened to you. This may relate to a stressful or traumatic event but does not have to.
In severe cases you might find it difficult to remember:
- who you are,
- what happened to you, or
- how you felt at the time of the trauma.
This is not the same as simply forgetting something. It is a memory ‘lapse’. A memory lapse is when you forget something that you usually remember. Like a name or where you put your keys.
It's like a brief ‘blank spot’ in your memory.You might remember the forgotten memory later. You might also still remember other things and live a normal life.
But you might also have flashbacks, unpleasant thoughts or nightmares about the things you found it hard to remember.
What is dissociative amnesia with dissociative fugue?
You may have dissociative amnesia with dissociative fugue.This is where you go somewhere else without remembering. You may not be aware you have gone somewhere in a dissociative fugue. You may or may not have travelled on purpose.
What is dissociative identity disorder (DID)?
If you have DID you might seem to have 2 or more different identities called ‘alternate identities.’
These identities might take control at different times. People used to call DID ‘multiple personality disorder’. But this is an outdated term.
What might happen when identities switch?
You might find that your behaviour changes depending on which identity has control. You might also have some difficulty remembering things that have happened as you switch between identities.Do researchers agree about DID?
There is some disagreement between researchers over the notion of DID.- Some researchers think people with DID have different identities.
- But other researchers think that that these are different parts of one identity which are not working properly together.
- These researchers suggest that DID is caused by experiencing severe trauma over a long time in childhood.
- By experiencing trauma in childhood, you take on different identities and behaviours to protect yourself.
- As you grow up these behaviours become more fully formed until it looks like you have different identities. Some researchers think the different parts of your single identity do not work properly together.
What is partial dissociative identity disorder?
This diagnosis is used when:
- You have 2 or more alternate identities, just as with DID.
- Your personality changes happen internally and are not obvious to other people. This is different to DID, where changes can be seen by other people.
- You do not experience amnesia during episodes of dissociation. This is different to DID, which has amnesia as a primary symptom.
What is other specified dissociative disorder?
This diagnosis is used when:
- Your symptoms are like those of another dissociative disorder.
- But you do not meet all the symptoms of that dissociative disorder.
- And your symptoms are not due to any substance or medication, or due to any other mental or physical health condition.
What is unspecified dissociative disorder?
This diagnosis is used when:
- You dissociate but do not fit into a specific dissociative disorder.
- Your psychiatrist chooses not to specify the reasons why you do not fit into a specific disorder.
What is depersonalisation or derealisation disorder (DPDR)?
The feelings of depersonalisation and derealisation can be a symptom of other conditions. It has also been found among people with frontal lobe epilepsy and migraines.
But it can also be a disorder by itself. This means it is a ‘primary disorder.’
There is some disagreement among professionals whether DPDR should be listed with other dissociative disorders at all.
How is DPDR different to other dissociative disorders?
DPDR has some differences to other dissociative disorders.In DPDR as a primary disorder you do not question your identity or have different identities at all. You may still be able to tell the difference between things around you. Though you might have feelings of a split self. That is where one self is observing and the other is doing an activity. Like an out-of-body experience.
There may be no symptoms of amnesia. Instead with DPDR you might feel emotionally numb and question what it feels like to live. We have explained this in more detail below.
You might have these feelings constantly rather than in episodes. It might not be caused by a traumatic or stressful event.
Many people think that this disorder might be more common than previously thought. This might be because of:
- a lack of information about it,
- patients who do not report their symptoms, and
- doctors who do not know enough about it, meaning they under-report the condition.
With DPDR you might have symptoms of depersonalisation or derealisation or both.
Depersonalisation
With depersonalisation you might feel ‘cut off’ from yourself and your body or like you are living in a dream. You may feel emotionally numb to memories and the things happening around you.
It may feel like you are watching yourself live. The experience of depersonalisation can be very difficult to put into words. You might say things like, ‘I feel like I do not exist anymore’ or ‘It is as if I am watching my life from behind glass’.Derealisation
If you have derealisation, you might feel cut off from the world around you. You might feel that things around you do not feel real. Or they might seem foggy or lifeless.To read more about the lived experiences of those living with DPDR, you can visit the Unreal website. Their details are in the Useful Contacts at the bottom of this page. They have blogs written by people who experience DPDR and their carers which you can read here.
What is dissociative neurological symptom disorder?
This diagnosis is used when:
- You have physical symptoms of dissociation, such as seizures, dizziness, or loss of speech, sight, or loss of hearing. You may experience numbness, burning, or tingling, or have balance problems.
- You do not have psychological symptoms of dissociation.
- Your symptoms are not due to any other physical or mental health condition.
What is trance disorder?
This diagnosis is used when:
- You experience episodes of dissociative trances where you lose awareness of yourself and your surroundings.
- During these episodes your identity is not ‘replaced’ with another identity, as in DID.
- During these episodes you may repeat certain movements or behaviours.
What is possession trance disorder?
This diagnosis is used when:
- You experience episodes of dissociative trances where you feel you are possessed by an external identity.
- The identity that possesses you is not a part of yourself, as in DID.
- You may feel this identity is spiritual or religious in nature.
-
There are different things that can cause you to dissociate. For example:
- traumatic events,
- seizure disorders, like epilepsy, and
- the use of drugs, like ketamine or cannabis.
-
If you think you have a dissociative disorder you can:
- See your GP
- Contact the NHS on 111 or go to their website.
If you need urgent help, see What if I need urgent help? below.
What should I take to my GP appointment?
Dissociative disorders are not as well-known as some other mental health conditions, like depression. This means that your GP might have limited knowledge about them.
You could take this information to your GP appointment. You can show it to your GP if you think it is necessary.
It might also help if you write down your symptoms before the appointment.
See our webpage on GPs and your mental health for more information.
What if I need urgent help?

Dissociation can be treated in lots of different ways. The type of treatment you get depends on which type of dissociative disorder you have.
What psychosocial treatments can help?
You will usually be offered talking therapies before you are offered medication. There are lots of different types of talking therapy.
The type of talking therapy you will be offered will depend on your symptoms or diagnosis.
How is psychotherapy used?
If you experience dissociation or a dissociative disorders (DID) then your doctors may think about long-term relationally based psychotherapy. This is a type of therapy where you talk about your relationships and thoughts.You might talk about your past. Your therapist can link the ways you think and act with things that have happened to you.
For DID, psychotherapy might be needed for a long time, with at least 1 session every week. How many sessions you have will depend on your situation and current wellbeing.
What is eye movement desensitisation and reprocessing (EMDR)?
You might benefit from a psychological therapy called eye-movement desensitisation and reprocessing (EMDR).EMDR can help you if who have memories of trauma that affect you.
During EMDR, you:
- make side-to-side eye movements, or tapping sounds, while thinking about the trauma, and
- you will process the memory, which happens on its own.
Before you start the therapy, the therapist will talk to you. They will plan how to support you through any hard parts of remembering the trauma.
Important warning: Before you have EMDR, ask the therapist to confirm that the EMDR has been specially adjusted for the treatment of dissociative disorders. This is because standard EMDR treatment is not suitable for the treatment of dissociative disorders and could make you worse.
You can watch this short video from the EMDR Association UK to learn more about the treatment.
What is cognitive behavioural therapy (CBT)?
Cognitive behavioural therapy (CBT) is another type of talking therapy.You will talk about the way your thoughts and feelings affect you. And how your behaviours may make this worse. You focus less on the past and try to change the way you think and behave.
Parts of CBT are recommended to treat DID, by helping you to change your thoughts and behaviours that come from trauma. A CBT approach has also been suggested for long-lasting depersonalisation and derealisation disorder (DPDR).
If you live with DPDR you might often worry about your symptoms. And think you have a serious mental illness or that something is wrong with your brain. CBT may help to change this way of thinking. It can reduce anxiety and depression that comes with this worrying. So, it may also reduce symptoms of DPDR.
See our webpage on Talking therapies for more information.
Can medications help?
Currently, there are no medications for dissociative disorders themselves. But you may take medication for some of your symptoms.
If you have episodes of dissociation, you might also experience depression or anxiety.
Some medications could help with this. For example, antidepressants could be used for depression, anxiety, and panic attacks.
See our webpage on Antidepressants for more information.
-
In the UK, the National Institute of Health and Care Excellence (NICE) publish guidelines on health conditions. These guidelines are a standard for NHS treatment.
At the time of writing, there are no NICE guidelines on dissociation or dissociative disorders. But this does not mean you should not be offered treatment.
If you think you are experiencing symptoms of a dissociative disorder, then explain this to your GP. They may refer you to a psychiatrist.
See our webpage on GPs and your mental health for more information.
-
If you are not happy with your treatment, you can:
- talk to your doctor about your care and treatment options,
- ask for a second opinion,
- get an advocate to help you speak to your doctor,
- contact your local Patient Advice and Liaison Service (PALS) here, or
- make a complaint.

You can learn to try and manage your symptoms by looking after yourself. It can help to learn how to notice when you are becoming unwell and know what your triggers are.
Not all techniques will work for everyone. It is important to find something that works for you. It also important to talk to your GP or person responsible for your care to discuss first.
Will keeping a diary help?
You might find it helpful to keep a diary. You could write about:
- how you felt over the day, or
- your goals that you want to achieve.
You could use it as part of cognitive behavioural therapy (CBT).
Diary-keeping can help people who live with depersonalisation or derealisation (DPDR). It can help to figure out what makes symptoms better or worse. This is to eventually gain control over your symptoms.
What are grounding techniques?
These techniques can be helpful for people who have been through trauma or who regularly dissociate.
They can help to ‘ground’ you in the here and now. This may help when experiencing flashbacks. Grounding works best when it is practiced regularly.
Different techniques may be helpful to different people. Some examples are:
- Focus on 3 things you can see, 3 things you can hear, and 3 things you can touch.
- Using your surroundings. Focus on all the details of everything that is around you. Try describing this to yourself either out loud or silently in your head. Use all your senses.
- Using words. You could try positive words or phrases about yourself.
- Using images. Try thinking of a place that you feel peaceful and safe without any traumatic memories.
- Using movement. For example, stand up, walk around or clap your hands, and breathe mindfully.
- Using objects. You should try and pick something personal that only has positive memories attached to it. Carry it around with you. Use it to remind yourself of who and where you are.
The following Rethink Mental Illness video might help. Scroll down to the ‘5-4-3-2-1 ground exercise video.
Also, the Survivors Trust have produced this guide on ‘Grounding techniques: Coping with flashbacks and distress’.
What about relaxation?
There are lots of different ways to relax. The important thing is to find something you enjoy doing. For example, cooking, reading or gardening. You might find that mindfulness helps.
You can get more information on mindfulness here.
How might exercise and diet help?
Exercise usually has a positive impact on our mental health. You can try jogging, swimming or walking more.
Eating more fresh fruits and vegetables can help. So can reducing the amount of fat, salt and sugar you eat. And reducing the amount of caffeine you drink can be helpful too.
You can find more information on our Physical activity and mental health webpage.
You can find more information about healthy foods and a balanced diet from the NHS here.
What about sleep?
If you sleep well, it can benefit your mental health.
See our webpage on on How can I improve my sleep?
See our webpage on Complementary and alternative treatments for mental health for more information.
Also, see our webpage on Worried about your mental health - How to get treatment and support for more information.

Some people with a dissociative disorder may also experience another mental health condition, such as anxiety or depression.
In some cases, this can make your dissociative disorder harder in day-to-day life. However, all these conditions are manageable and treatable.
For more information see our webpages on the following:
What are dissociative seizures?
Some people who live with dissociative disorders may also experience physical symptoms, such as seizures. These are called dissociative seizures. They are also commonly referred to as:
- non-epileptic attack disorder (NEAD), or
- non-epileptic seizures (NES).
Dissociative seizures can be hard to get diagnosed. They are sometimes wrongly diagnosed as epilepsy. It can sometimes be hard to tell the difference between a dissociative and epileptic seizure.
Some tests can be done to diagnose epileptic seizures, by using an electroencephalogram, better known as an EEG. An EEG is a test that detects electrical activity in your brain. It uses small, metal discs attached to your scalp. An EEG cannot diagnose dissociative seizures.
Dissociative seizures happen because of how you feel or what you are going through emotionally. Not because there is something wrong with your body or brain physically. If you experience dissociative seizures, you may be referred to an NHS mental health team.
-
What support can I get?
If you are a carer, friend or relative of someone living with a dissociative disorder, you can get support.
You can get peer support through carer support groups. You can search for local groups in your area on the following websites:
If you need more practical support, you can ask your local authority for a carer’s assessment. You might be able to get support from your local authority.
As a carer you should be involved in decisions about your relative’s care planning. But you can only be involved if your relative agrees to this. If they do not agree, their healthcare professionals cannot usually share information about them with you.
For more information see our webpages on the following:
- Carer’s assessments – Under the Care Act 2014
- Confidentiality, information and your loved one – For loved ones of people living with mental illness
You can find more information about What benefits are available for mental health carers? here.
How can I support the person I care for?
You might find it helpful to learn about their symptoms, treatments and self-care options. You can use this to support and encourage them to get help and stay well.
You should also be aware of what you can do if you are worried about their mental state. Keep the details of their mental health team or GP handy and discuss a crisis plan with them.
