What Is Dissociation? Types, Causes, Symptoms & Treatment

Dissociation is a coping mechanism that some people use to deal with overwhelming or traumatic experiences. It involves a disconnection or detachment from one’s thoughts, emotions, sensations, or surroundings.

Dissociative experiences can range from mild (e.g., daydreaming) to severe (e.g., dissociative identity disorder). Some common symptoms of dissociation include feeling numb, spaced out, or disconnected from reality.

It’s important to seek professional help if dissociation is interfering with your daily life or causing distress.

Experiencing dissociation feels like observing oneself from a distant and disconnected perspective, as if the mind and body are operating separately.

What Does Dissociation Feel Like?

People who dissociate may feel detached from their bodies or feel as though the world around them is not real. Dissociation can happen for many people as a natural response to trauma that they cannot control.

Experiences of dissociation can last for a relatively short amount of time, as short as a few hours, or this feeling can last for much longer, as long as weeks or months.

Many people may experience dissociation during their lifetime, as it can be a way for the mind to cope with too much stress. If an individual dissociates for a long time, this may develop into a dissociative disorder.

Dissociation may become the main way someone copes with stressful experiences.

Dissociation can be detrimental as it can disrupt areas of functioning that usually work together automatically. These areas are consciousness, memory, identity, and awareness of the self and the environment.

People who experience dissociation may experience something called depersonalization. This is a feeling of being disconnected from the body, being outside of oneself, and observing your actions, thoughts, or feelings from a distance.

Also, people who disassociate may experience derealisation. This is where the world around the individual does not feel real, as if living in a movie.

The surroundings may appear distorted, two-dimensional, or artificial because of derealisation. Therefore, dissociation can range anywhere from a mild sense of detachment to a more severe disconnection from reality.

Below are some quotes taken from individuals who have experienced dissociation.

Types of Dissociation

Dissociative identity disorder

Dissociative identity disorder (DID), renamed from multiple personality disorder in 1994, is a disorder that is categorized by the presence of two or more identities or personalities that an individual has.

These identities recurrently take control of the individual’s behavior, as well as resulting in them forgetting important personal information.

An individual with DID may ‘switch’ to the alternating identities and may feel the presence of two or more people talking inside their head.

The other personalities may have their own names, personal histories, characteristics, style of voice, and mannerisms.

Depersonalization-derealisation disorder

This type of dissociative disorder is associated with the presence of persistent or recurrent experiences of depersonalization, derealization, or both.

People with this disorder may feel like a stranger to themselves and/or to their surroundings (their surroundings may feel unreal).

Individuals with this disorder may also have a distorted sense of time, altered bodily perceptions, and numb emotions and bodily senses.

Dissociative amnesia

Dissociative amnesia is thought to be the most common dissociative disorder, with different types of amnesia branching from this condition. The main symptom of this disorder is memory loss which is more severe than typical forgetfulness.

One type of dissociative amnesia is localized amnesia, which is the failure to recall events of a specific period of time. Selective amnesia is when some, but not all, events can be recalled during a period of time.

Generalized amnesia, which is the rarest type, is when an individual’s life history is completely forgotten, and they may forget their identity.

Other specified dissociative disorders

This category includes dissociative disorders that do not meet the full criteria for any specific dissociative disorder but still cause significant distress or impairment in functioning.

Examples of other specified dissociative disorders may include atypical dissociative disorder, which involves dissociative symptoms that do not fit the criteria for any specific dissociative disorder but still cause significant distress or impairment, or acute dissociative reactions, which are temporary episodes of dissociation that occur in response to a stressful or traumatic event.

Unspecified dissociative disorder

Unspecified dissociative disorder is applied to people whose symptoms are characteristic of a dissociative disorder but do not meet the full criteria for any of the specific disorders mentioned above.

This unspecified category is often used in situations where a doctor or clinician chooses not to specify which, if any, disorder an individual may have due to there being insufficient information to make an actual diagnosis.

Signs of Dissociative Disorders

Symptoms associated with dissociative disorders vary depending on the type of disorder being experienced. Please note that dissociation can manifest in different ways and with varying degrees of severity.

5 core components of dissociative disorders
5 core components of dissociative disorders

It is understood there are five core components of dissociative disorders. Each dissociative disorder could be described and understood using a combination of one of these five core symptoms:

  • Amnesia – memory loss of certain time periods, events, people, and personal information, which are recurrent.

    These gaps in memory can vary from several minutes to years and are inconsistent with typical forgetting.

  • Depersonalization – a sense of detachment or disconnection from oneself and their emotions. This can include feeling like a stranger to oneself, being on autopilot, or feeling like a part of their body does not belong to them.

    Often, individuals who experience depersonalization may induce injuries to themselves in order to feel ‘real.’

  • Derealization – the perception of the familiar people and surroundings around an individual as being distorted and unreal. For instance, close friends or relatives may not seem real to an individual experiencing derealization.

    The world around them may also appear distorted or blurred or artificial in general. Some episodes of derealization may happen during flashbacks, whereby an individual may feel much younger than they are and feel as if the present environment is unreal at that time.

  • Identity confusion – some people with dissociative disorders may have a blurred sense of their own identity. This may involve an inner struggle regarding an individual’s sense of self or identity, with feelings of conflict and uncertainty.

  • Identity alteration – this is a sense of acting like a different person some of the time and in different situations.

    Individuals who experienced this may use different names depending on the situation, realize they have items that they do not recognize, or may have learned a new skill that they have no recollection of learning.

Usually, if any of the core components of dissociation are being experienced, that are persistent, cause significant distress, disrupt important areas of functioning, and cannot be explained by other means (e.g., through alcohol or mind-altering drugs), this could be an indication that an individual may be experiencing a dissociative disorder.

Although, keep in mind that only a professional should diagnose a dissociative disorder, and advice should be sought if someone believes they may be experiencing the above signs.

Why Do I Dissociate?

Dissociation is a psychological experience that can occur in response to various factors, including trauma, stress, or other types of overwhelming experiences. Below are some potential causes of dissociation.

Note that these causes may only contribute to fleeting dissociative feelings. If the symptoms of dissociation persist and they meet the diagnostic criteria, this could result in a dissociative disorder.

Trauma

Trauma is a significant cause of dissociation. This is when an individual has experienced a traumatic event and/or abuse, particularly during early childhood.

This dissociation can be a possible way of helping a person distance themselves or cope with a traumatic situation.

A possible cause may stem from repeated emotional and/or physical abuse in childhood. Similarly, disrupted attachment between the child and their parent/primary caregiver, such as being neglected or failing to respond to the child, can cause dissociation.

Other factors include a child witnessing domestic abuse or witnessing the death of a relative or close friend. Also, if a parent/caregiver has a mental health condition that is very debilitating, affecting their parenting, this may also trigger dissociation in the child.

Particularly, if trauma has been experienced before the age of 5, this makes it more likely that the child will dissociate. The average age of onset of dissociative disorders is 16, and 95% of people typically experience symptoms before the age of 25.

Early childhood trauma can prevent a child from forming a unified sense of self or personality during their earliest years. Instead, the trauma may cause different ‘behavioral states’ to become more dissociated, resulting in multiple identities being developed.

Stress

High levels of stress can trigger dissociation. Stressful life events, such as divorce, job loss, or the death of a loved one, can also lead to dissociation.

Stress can cause dissociation as a coping mechanism to deal with overwhelming emotions or sensations. When a person experiences stress, their body’s natural response is to activate the “fight or flight” response, which prepares the body to deal with a perceived threat.

However, if the stressor is ongoing or the person is unable to escape the stressor, the body may enter a state of freeze or shutdown (dissociation).

For example, if a person experiences a traumatic event such as a car accident, their body and mind may become overwhelmed by the intensity of the experience.

To cope, the person may dissociate, feeling detached from their surroundings, emotions, or even their own body. This can help the person to distance themselves from the traumatic event, at least temporarily, and avoid the intense emotions associated with it.

Substance use

Another known cause for dissociative disorders may be substance use. The use of some recreational drugs, such as ecstasy and Ketamine, can cause some feelings of dissociation whilst taking them.

This dissociation would only be considered a disorder if the signs of dissociation continued after stopping using the drugs.

Anxiety and depression

Anxiety and depression may cause dissociation as a way to cope with overwhelming emotions or thoughts.

For anxiety, the associated fear and worry can become so intense that the person may dissociate to protect themselves from the emotional pain.

Similarly, depression can also lead to dissociation as a way to cope with overwhelming feelings of sadness or hopelessness.

In both cases, dissociation can provide a temporary escape from the intensity of the emotions or thoughts associated with anxiety or depression.

Sleep deprivation

Sleep deprivation can cause dissociation as a result of the brain’s inability to process information and regulate emotions and behavior effectively.

During sleep, the brain undergoes critical processes for consolidating memories, processing emotions, and restoring energy levels. When a person is sleep-deprived, these processes are disrupted, leading to a range of cognitive and emotional impairments, which may trigger dissociation.

A sleep-deprived person may experience difficulties with focusing, making decisions, or processing sensory information. They may also have trouble distinguishing between reality and imagination or experience depersonalization.

How Can Dissociative Disorders be Managed?

The treatment for dissociation depends on the underlying cause and severity of the symptoms.

Self-care

For individuals who experience mild dissociative symptoms, self-care techniques such as stress reduction and relaxation exercises can be helpful. These techniques can include deep breathing, meditation, yoga, or other mindfulness practices.

Mindfulness helps individuals to focus on the present moment, paying attention to what is happening inside them. This can help people with dissociative disorders to pay attention to their thoughts, feelings, and sensations, as well as focus on what is happening around them (such as what they can see, hear, smell, and touch).

Ensuring that good sleep hygiene is prioritized, as well as refraining from abusing substances, can also help to manage dissociative symptoms.

Psychotherapy

For individuals with more severe dissociative symptoms or a dissociative disorder, professional treatment such as psychotherapy may be necessary.

Psychotherapies are a collection of talking therapies that usually involve discussing the symptoms and techniques to help cope, working with the other identities (for DID), and helping the individual to understand their condition, including what may be the underlying cause.

Cognitive behavioral therapy (CBT) is a type of psychotherapy that helps people identify and modify thought patterns that may be disturbing and negatively influence behavior and emotions.

CBT involves working together with the therapist to practice new thinking skills, set goals, and problem-solve. It also involves completing CBT tasks between therapy sessions, so these skills are thoroughly practiced, becoming a habit.

CBT has shown effectiveness for many people, with a study reporting that those who completed CBT had significant reductions in their levels of dissociation and depersonalization, with 29% no longer meeting the criteria for dissociative disorders after treatment (Hunter et al., 2005).

Dialectical behavior therapy (DBT) is another type of CBT. Its main goal is to help individuals develop healthy ways to cope with stress, regulate their emotions, and improve relationships with others. DBT has a big focus on mindfulness skills.

Eye Movement Desensitization and Reprocessing (EMDR) is a type of therapy that can be effective in treating trauma-related dissociation. It involves guided eye movements that help the individual process traumatic memories and reduces the associated distress.

Likewise, creative therapies such as art therapy, music therapy, and other creative therapies can be helpful in treating dissociation by providing an outlet for self-expression and a way to process traumatic experiences.

Medication

Currently, there are no medications that are specifically targeted to treat dissociative disorders themselves. However, people with these conditions may take medication for some symptoms or other conditions they may have alongside dissociation.

For instance, if someone is experiencing dissociation, they may also have a depressive or anxiety disorder. Some medications, such as antidepressants, can be used for depressive and anxious symptoms. Similarly, benzodiazepines, a type of sedative medication, can also be used for anxiety.

Overall, the treatment for dissociation is typically a combination of therapy, medication, and self-care techniques. It’s important to work with a mental health professional to develop an individualized treatment plan that addresses the specific needs of each person.
