Dissociative Disorders

What Are Dissociative Disorders?

Dissociative disorders are mental health conditions that involve a disconnection between thoughts, memories, emotions, identity, behaviour, and surroundings. These disruptions can affect a person’s sense of self, awareness, and ability to function in daily life. Dissociation is often understood as the mind’s way of coping with overwhelming stress or trauma, particularly experiences that occur during childhood. Symptoms may be temporary or long-lasting and can range from feeling detached from reality to experiencing significant memory gaps or shifts in identity.

What Does It Feel Like?

Living with a dissociative disorder means experiencing disruptions in the normal connections between thoughts, memories, feelings, actions, and identity that most people take for granted.

Types of Dissociative Disorders

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) recognises several distinct dissociative disorders.

Depersonalisation/Derealisation Disorder

This disorder involves persistent or recurrent experiences of depersonalisation, derealisation, or both.

Depersonalisation

• Feeling detached from oneself, as if observing from outside
• Feeling like an automaton or living in a dream
• Emotional or physical numbing
• Feeling like thoughts, feelings, or actions are not one's own

Derealisation

• Feeling that surroundings are unreal, dreamlike, or distorted
• Feeling emotionally disconnected from familiar people
• Experiencing the environment as artificial or lacking in depth
• Feeling like familiar places are strange or unrecognisable

Key Features

• Reality testing remains intact (person knows the feelings are not real)
• Symptoms cause significant distress or impairment
• Symptoms are not due to substance use or medical conditions
• May be triggered by stress, fatigue, or sensory deprivation

Dissociative Amnesia

This disorder involves inability to recall important personal information, usually of a traumatic or stressful nature.

Types of Memory Loss

• Localised amnesia: Cannot remember events during a specific time period
• Selective amnesia: Can remember some but not all events during a time period
• Generalised amnesia: Cannot remember anything about their life and identity
• Continuous amnesia: Cannot remember events from a specific time up to the present
• Systematised amnesia: Loss of memory for specific categories of information

Dissociative Fugue Specifier

• Sudden, unexpected travel away from home or work
• Inability to recall one's past
• Confusion about personal identity or assumption of new identity
• Significant distress or impairment in functioning

Dissociative Identity Disorder (DID)

Formerly known as Multiple Personality Disorder, DID is characterised by the presence of two or more distinct identity states.

Core Features

• Identity disruption: Two or more distinct personality states or identities
• Amnesia: Gaps in recall of everyday events, personal information, or traumatic events
• Distress or impairment: Symptoms cause significant problems in functioning
• Cultural considerations: Not a normal part of accepted cultural or religious practice

Identity States Characteristics

• Each may have its own name, age, gender, and personal history
• Different identities may have distinct voices, mannerisms, and preferences
• May have different memories, skills, and knowledge
• Switching between identities may be sudden or gradual
• Some identities may be aware of others, while some may not

Other Specified Dissociative Disorder (OSDD)

This category includes dissociative symptoms that don't fully meet criteria for other disorders.

OSDD-1 (Partial DID)

• Type 1a: Identity states without amnesia
• Type 1b: Amnesia without distinct identity states

Other presentations

• Chronic and recurrent mixed dissociative symptoms
• Identity disturbance due to prolonged coercive persuasion
• Acute dissociative reactions to stressful events
• Dissociative trance not part of cultural or religious practice

Unspecified Dissociative Disorder

Used when dissociative symptoms cause distress or impairment but don't meet full criteria for any specific dissociative disorder, and the clinician chooses not to specify the reason.

Causes and Risk Factors

Dissociative disorders typically develop as a response to trauma, particularly during childhood when the personality is still developing.

Primary Risk Factors

Childhood Trauma

• Physical abuse: Severe or repeated physical violence
• Sexual abuse: Any form of sexual exploitation or assault
• Emotional abuse: Persistent emotional cruelty, humiliation, or rejection
• Neglect: Failure to provide basic physical or emotional needs
• Witnessing violence: Exposure to domestic violence or community violence

Trauma Characteristics

• Early onset: Trauma occurring before age 6-9 is particularly significant
• Chronic nature: Repeated or ongoing traumatic experiences
• Severity: More severe trauma increases risk
• Perpetrator relationship: Trauma by caregivers or trusted figures
• Lack of support: Absence of protective or supportive relationships

Biological Factors

• Genetic predisposition: Family history of dissociative or trauma-related disorders
• Neurobiological factors: Differences in brain structure and function
• Temperament: High sensitivity or emotional reactivity
• Developmental factors: Disruptions during critical developmental periods

Environmental Factors

• Family dysfunction: Chaotic, unpredictable, or invalidating family environments
• Social isolation: Lack of social support or protective relationships
• Cultural factors: Cultural attitudes toward trauma and mental health
• Socioeconomic stress: Poverty, discrimination, or social instability

Protective Factors

• Secure attachment: Stable, nurturing early relationships
• Social support: Strong support networks and protective relationships
• Resilience factors: Personal strengths and coping abilities
• Early intervention: Recognition and treatment of trauma symptoms
• Stable environment: Consistent, safe living situations

Developmental Considerations

• Critical periods: Certain developmental stages are more vulnerable
• Attachment formation: Disruptions in early attachment relationships
• Identity development: Interference with normal identity formation
• Coping mechanisms: Development of dissociation as a survival strategy
