Dissociative disorders are psychological conditions where an individual's conscious awareness becomes dissociated or separated from their previous memories, thoughts, and feelings.

In rare cases, dissociative disorders can cause people to enter a dissociative fugue state, where they suddenly lose memory or completely change their identity without recalling their past, usually in response to overwhelming stress.

Individuals with dissociative disorders may struggle to integrate various aspects of consciousness, causing experiences to feel disconnected or as if they are happening to someone else.

Dissociative disorders are closely associated with trauma and stress. Individuals with post-traumatic stress disorder or PTSD often exhibit symptoms of dissociation.

Psychologists view dissociation as a coping mechanism for managing intense stress and overwhelming trauma, allowing individuals to distance themselves from pain mentally.

Studies link these disorders to lower hippocampus and amygdala volumes. The hippocampus consolidates memories and creates a coherent understanding of life experiences, while the amygdala processes traumatic emotions, contributing to fragmented and dysregulated emotional experiences.
