Dissociative disorders are a range of conditions that can cause physical and psychological problems.
Some dissociative disorders are very short-lived, perhaps following a traumatic life event, and resolve on their own over a matter of weeks or months. Others can last much longer.
Symptoms of a dissociative disorder
Symptoms of dissociative disorder can vary but may include:
- feeling disconnected from yourself and the world around you
- forgetting about certain time periods, events and personal information
- feeling uncertain about who you are
- having multiple distinct identities
- feeling little or no physical pain
Some people with dissociative disorders have seizures. These can vary from fainting to something more like an epileptic seizure.
Dissociation is a way the mind copes with too much stress.
Periods of dissociation can last for a relatively short time (hours or days) or for much longer (weeks or months).
Many people with a dissociative disorder have had a traumatic event during childhood. Dissociation can happen as a way of coping with it.
Types of dissociative disorder
There are several different types of dissociative disorder.
The 3 main types are:
- depersonalisation-derealisation disorder
- dissociative amnesia
- dissociative identity disorder
Depersonalisation-derealisation disorder
Depersonalisation is where you have the feeling of being outside yourself and observing your actions, feelings or thoughts from a distance.
Derealisation is where you feel the world is unreal. People and things around you may seem "lifeless" or "foggy".
You can have depersonalisation or derealisation, or both together. It may last only a few moments or come and go over many years.
Dissociative amnesia
Someone with dissociative amnesia will have periods where they cannot remember information about themselves or events in their past life.
They may also forget a learned talent or skill.
These gaps in memory are much more severe than normal forgetfulness and are not the result of another medical condition.
Some people with dissociative amnesia find themselves in a strange place without knowing how they got there.
They may have travelled there on purpose, or wandered in a confused state.
These blank episodes may last minutes, hours or days. In rare cases, they can last months or years.
Dissociative identity disorder
Dissociative identity disorder (DID) used to be called multiple personality disorder.
Someone diagnosed with DID may feel uncertain about their identity and who they are.
They may feel the presence of other identities, each with their own names, voices, personal histories and mannerisms.
The main symptoms of DID are:
- memory gaps about everyday events and personal information
- having several distinct identities
Associated conditions
Someone withadissociative disorder may also have other mental health conditions, such as:
- medically unexplained symptoms
- post-traumatic stress disorder (PTSD)
- depression
- mood swings
- anxietyandpanic attacks
- suicidal tendenciesorself-harm
- an eating disorder
- obsessive compulsive disorder (OCD)
They may also have problems sleeping (insomnia).
Causes of dissociative disorder
There are many possible causes of dissociative disorders, including previous traumatic experience.
Someone with a dissociative disorder may have experienced physical, sexual or emotional abuseduring childhood.
Some people dissociate after experiencing war, kidnapping or even an invasive medical procedure.
Switching off from reality is a normal defence mechanism that helps the person cope during a traumatic time.
It's a form of denial, as if "this is not happening to me".
It becomes a problem when the environment is no longer traumatic but the person still acts and lives as if it is, and has not dealt with or processed the event.
Diagnosing dissociative disorders
A GP may examine you and do some tests to check if another illness might be the cause of your symptoms.
They may also refer you to a mental health specialist for a full assessment.
Assessment
The specialist who carries out your assessment should have a good understanding of dissociative disorders.
The assessment may include questions about your thoughts, feelings, behaviour and your symptoms.
It's important to be honest about your symptoms and not to feel ashamed or embarrassed, so you can receive the help and support you need.
Treatments for dissociative disorders
Many people with a dissociative disorder make a full recovery with treatment and support.
Talking therapies
Talking therapies are often recommended for dissociative disorders.
The aim of talking therapies such ascounsellingor psychotherapy is to help you cope with the underlying cause of your symptoms, and to learn and practise techniques to manage the periods of feeling disconnected.

What to do if you're worried about someone
If you're worried that someone you know may be considering suicide, try to encourage them to talk about how they're feeling.
Listening is the best way to help. Try to avoid offering solutions and try not to judge.
If they have previously been diagnosed with a mental health condition, such as depression, you can speak to a member of their care team. They will offer help and advice but cannot share information about the person without consent.

Talking to your partner, family and friends about your experience of dissociative disorder can help them understand how you feel.
