Study Notes on Dissociative Disorders and Cognitive Mental Disorders

Everyday Dissociation

  • Normal Experience: Driving on autopilot; a brief mental state where one is disconnected from the immediate environment.
  • Implications: Usually brief; can be snapped out of by external stimuli.
  • Dissociation as a Disorder: For some, dissociation becomes pervasive and impacts daily life functioning, termed dissociative disorder.

Dissociative Disorders

  • Definition: A group of disorders characterized by impaired awareness of one's actions, thoughts, sensations, and identity.
  • Cause: Typically stems from trauma, such as early childhood abuse or neglect; serves as an adaptation mechanism to cope with negative feelings and experiences.
  • Types of Dissociative Disorders:
    • Depersonalization/Derealization Disorder (least severe): Detachment from self or the world.
    • Dissociative Amnesia (moderate severity): Inability to recall important personal information.
    • Dissociative Identity Disorder (most severe): Presence of two or more distinct identities or personality states.

Types of Dissociative Disorders

  • Depersonalization/Derealization Disorder:

    • Depersonalization: Feeling detached from oneself (e.g., as if watching oneself from outside).
    • Derealization: Feeling that the world around is not fully real.
    • Symptoms: Emotional/physical numbness, difficulty in relationships, deadpan manner.
    • Severe Cases: Difficulty recognizing familiar people or places, altered sense of time, brain fog, lightheadedness, anxiety.

  • Dissociative Amnesia:

    • Definition: Blockage or loss of personal information, often surrounding traumatic events.
    • Types:
    • Localised Amnesia: Inability to recall a specific traumatic event (e.g., forgetting a car accident).
    • Generalized Amnesia: Complete loss of memory about the past.
    • Systematised Amnesia: Loss of memory for certain categories of information tied to trauma (e.g., forgetting everything related to an abuser).
    • Continuous Amnesia: Inability to store new memories after an event; constant present-focused awareness.

  • Dissociative Identity Disorder (DID):

    • Definition: A condition where two or more distinct identities are present within a single individual.
    • Types:
    • Covert DID: Sudden shifts in perception, thought, or feeling, often hearing a distinct voice of another identity.
    • Overt DID: Multiple personalities that assume control over a person's identity.
    • Symptoms Include: Amnesia for personal history, discovering unexplained injuries or possessions, potential suicidal behavior, high prevalence of suicide attempts (around 75%).

Comparison and Diagnosis of Dissociative Disorders

  • Difficulty in Diagnosis: Symptoms can overlap with substance intoxication, brain trauma, psychiatric conditions such as anxiety, schizophrenia, and bipolar disorder.
  • Key Distinctions: Symptoms of dissociative disorders persist for years, while those of anxiety disorders last minutes to hours.

Treatment Options for Dissociative Disorders

  • Psychotherapy: Common treatment modality focusing on processing trauma.
  • Dissociative Identity Disorder Treatment Goals: Facilitate the merging of identities into a single, integrated system, improving functioning.

Summary of Dissociative Disorder Spectrum

  • Spectrum Severity:
    • Least Severe: Depersonalization/Derealization Disorder.
    • Moderate Severity: Dissociative Amnesia.
    • Most Severe: Dissociative Identity Disorder.

Definitions of Key Terms and Concepts

  • Dissociative Fugue: Temporary disorientation and wandering away from home; potential amnesia regarding personal history.
  • Cognitive Processes in Dissociation: Inability to process trauma can lead to repressed memories, impacting individual’s functioning due to fear of reliving traumatic past.

Specific Examples of Trauma-Induced Amnesia Types

  • Localized Amnesia: Example - a person in a severe car accident may recall only driving and waking up in a hospital.
  • Selective Amnesia: Example - remembering driving but forgetting the moments leading up to a traumatic event.
  • Generalized Amnesia: Example - complete disconnection from past identity, often referred to as John Doe/Jane Doe.
  • Continuous Amnesia: Example - character from 'Finding Nemo', person retains memories of present but forgets everything that occurred previously.
  • Systematised Amnesia: Example - a survivor of repeated abuse may forget interactions with the abuser yet feel discomfort on seeing them in social situations.

Dissociative Identity Disorder (DID) - Further Analysis

  • Variability in Experiences: Individuals with different identities may exhibit varied physiological responses based on personality traits; emotional responses can also vary greatly.
  • Therapeutic Approach: Focus on integrating identities while monitoring risk factors such as potential self-harm.

Cultural Impact on Understanding Dissociative Disorders

  • Historical Context: Media portrayals (e.g., Sybil) shaped public perception but often led to over-diagnosis and skepticism about the existence of DID, raising ethical concerns about the influence of therapy techniques.
  • Caution with Diagnosis: Vigilance is needed to differentiate between similar symptoms to avoid misdiagnoses such as depression masquerading as dementia.

Cognitive Mental Disorders

  • Delirium vs. Dementia:
    • Delirium: Acute and usually reversible due to identifiable causes (e.g., infections, medications); beginning symptoms may involve confusion, hallucinations, or delusions.
    • Dementia: A chronic, progressive disorder with slow cognitive decline over years, leading to loss of function and independence due to deteriorating neurological health.

Prevention and Management of Cognitive Disorders

  • Delirium Prevention Strategies: Ensure regular sleep, hydration, proper nutrition, minimal medication side effects through careful management, and assessment of risk factors leading to delirium.
  • Dementia Management: Psycho-social therapies, reliable medication regimens to slow progression, and adjustments in lifestyle (cognitive engagement, nutrition, exercise).

Conclusion

  • Understanding Dissociative Disorders: These conditions, often traumatological in nature, require careful diagnosis and a sensitive, evidence-based therapeutic approach to enable recovery and functioning improvement.
