NCLEX Review Guide: Dissociative Disorders in Mental Health

Definition and Overview

• Dissociative disorders involve disruption in consciousness, memory, identity, or perception of the environment, typically resulting from psychological trauma or severe stress.
• These disorders serve as a protective mechanism where the mind separates or disconnects from thoughts, feelings, memories, or sense of identity to cope with overwhelming experiences.
• Most commonly develops in childhood as a response to abuse, neglect, or severe trauma, though symptoms may not appear until adulthood.

Major Classifications

• Dissociative Identity Disorder (DID): Presence of two or more distinct personality states with recurrent gaps in memory for everyday events, personal information, or traumatic events.
• Dissociative Amnesia: Inability to recall important personal information, usually of a traumatic or stressful nature, that is inconsistent with ordinary forgetting.
• Depersonalization/Derealization Disorder: Persistent experiences of feeling detached from oneself (depersonalization) or surroundings feeling unreal (derealization).

Signs and Symptoms

• Memory disturbances: Gaps in memory, inability to recall personal information, or finding evidence of activities they don't remember doing.
• Identity confusion: Uncertainty about who they are, feeling like different people at different times, or hearing voices inside their head.
• Depersonalization symptoms: Feeling detached from body, observing themselves from outside, or feeling like they're in a dream or movie.
• Associated symptoms: Depression, anxiety, substance abuse, self-harm behaviors, and suicidal ideation are common comorbidities.

Priority Nursing Actions

1. Ensure safety first - Assess for suicidal ideation, self-harm behaviors, and ability to care for self safely.
2. Establish therapeutic relationship - Use calm, non-judgmental approach and avoid challenging the client's reality during acute episodes.
3. Orient to reality gently - Provide orientation to person, place, and time without being confrontational about memory gaps.
4. Document thoroughly - Record all behaviors, memory gaps, and personality changes objectively for treatment planning.
5. Collaborate with treatment team - Work closely with psychiatrist, psychologist, and social worker for comprehensive care.

Evidence-Based Interventions

• Psychotherapy is the primary treatment, focusing on integration of memories and identity rather than elimination of alternate personalities.
• Trauma-focused therapy: Helps clients process traumatic experiences safely and develop healthy coping mechanisms.
• Medication management: No specific medications for dissociative disorders, but antidepressants and anxiolytics may treat comorbid conditions.
• Grounding techniques: Teaching clients to use sensory experiences (5-4-3-2-1 technique) to stay connected to present reality.
