Learn the main types of dissociative disorders, symptoms, causes, and treatment options. Understand dissociation and how therapy can help recovery.
Dissociation is a mental process where a person feels disconnected from their thoughts, memory, emotions, or sense of reality. This experience can make daily life confusing and stressful. People may feel detached from their body, forget important events, or feel like the world around them is not real. These symptoms are part of a group of mental health conditions called dissociative disorders.
Dissociation is often linked to childhood trauma, abuse, severe stress, or overwhelming experiences. According to the American Psychiatric Association, dissociation is described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a disruption in consciousness, identity, memory, or perception.

Understanding the types of dissociative disorders is an important step toward healing.
Dissociation is a coping response the brain may use when someone experiences intense trauma or danger. It is like the mind temporarily disconnects to protect itself.
When dissociation happens, people may notice changes in:
For some people, dissociation happens occasionally during stressful situations. But for others, it becomes a serious mental health disorder that requires treatment.
Dissociation often develops as a response to traumatic events such as:
The brain may create distance from painful experiences to help the patient cope. While this response may help during trauma, it can later create serious problems with identity, memory, and everyday functioning.
The Diagnostic and Statistical Manual of Mental Disorders identifies several main types of dissociative disorders. Each disorder affects memory, identity, and awareness in different ways.
Dissociative Identity Disorder (DID) is one of the most well-known dissociative disorders. In this condition, a person has two or more distinct identities or personality states.
Each identity may have its own:
People with DID may experience gaps in memory or episodes of amnesia where they cannot remember events, conversations, or personal information.
DID is strongly linked to severe childhood trauma, especially:
The mind may create separate identity states as a coping method to manage overwhelming experiences.
Common symptoms include:
Some people with DID also experience other mental health conditions like bipolar disorder, borderline personality disorder, or substance abuse.
Dissociative amnesia occurs when a person cannot remember important personal information, often related to trauma or stress.
This type of amnesia is different from dementia or medical memory problems because the brain structure is usually normal.
There are several patterns of memory loss.
Localized Amnesia
A person cannot remember events from a specific period of time, often during or after trauma.
Selective Amnesia
Only certain parts of a traumatic event are forgotten.
Generalized Amnesia
The person forgets large portions of their life, including identity and personal history.
Continuous Amnesia
The person keeps forgetting new information after a certain point.
A rare form of dissociative amnesia is called dissociative fugue.
During a fugue state, a person may:
When the fugue ends, the person may feel confused or distressed about what happened.
Another major type of dissociative disorder is Depersonalization/Derealization Disorder.
This condition causes persistent feelings of detachment from the body or surroundings.
Depersonalization occurs when a person feels disconnected from their own body or thoughts.
They may feel like they are:
Derealization happens when the world feels unreal or dreamlike.
People may feel that:
Although perception changes, people with this disorder usually know the feeling is not real.
Dissociative disorders often appear with other mental health conditions. This can make diagnosis and treatment more complex.
Many people with dissociation experience high levels of anxiety and fear. The body may stay in a constant state of stress, which can worsen symptoms.
PTSD often overlaps with dissociative symptoms because both are connected to trauma and emotional distress.
Some individuals may also experience borderline personality disorder or other personality disorder conditions that affect relationships and emotional stability.
Dissociation may appear alongside mood disorders such as:
Some individuals use substances to cope with emotional pain.
This can lead to:
Several factors can increase the risk of developing a dissociative disorder.
Repeated trauma in early life is one of the strongest risk factors.
This may include:
Long-term stress from life events such as violence, disasters, or loss can contribute to dissociation.
People with other mental health conditions may be more vulnerable to dissociation.
Drug or alcohol misuse can increase dissociation symptoms and affect brain function.
Diagnosis usually begins with a detailed evaluation by a mental health professional trained in psychiatry or psychology.
During an assessment, a clinician may review:
The clinician may compare symptoms to the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders.
Sometimes doctors check for other medical causes of memory problems, such as:
In some situations, patients first seek help in an emergency department due to confusion or severe distress.
Treatment often focuses on improving stability, emotional safety, and long-term recovery.
Therapy is the main treatment for dissociative disorders. It helps people understand trauma, manage symptoms, and build healthy coping skills.
Common therapy approaches include:
These treatments help patients improve emotional regulation and reconnect with memories safely.
There is no specific medicine that cures dissociative disorders. However, doctors may prescribe medication to treat related symptoms such as:
Many therapy programs teach practical coping strategies such as:
These tools help people stay connected to the present moment.
Recovery from dissociative disorders takes time, patience, and professional support.
With treatment, many people can:
Support from a trained mental health professional can make a major difference in recovery.
If someone experiences severe distress, thoughts of self-harm, or crisis, immediate help is available through the Suicide and Crisis Lifeline (988).
It may be time to seek professional help if someone experiences:
Early treatment can improve long-term outcomes and help prevent worsening symptoms.
The three primary types are dissociative identity disorder, dissociative amnesia, and depersonalization/derealization disorder. Each affects memory, identity, and perception differently.
Most dissociative disorders develop after severe trauma, especially childhood trauma, abuse, neglect, or overwhelming stress.
Yes. Treatment often includes therapy, coping skills, and sometimes medication to manage related symptoms such as anxiety or depression.
Dissociative disorders are considered relatively rare but may be underdiagnosed because symptoms can overlap with other mental health conditions.
A person should seek help if dissociation affects memory, daily functioning, relationships, or emotional well-being.
