Dissociative Disorders01:27

Dissociative Disorders

830
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

1.6K
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Dissociative Amnesia

896
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Psychosurgery

2.2K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.4K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

980
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Summary

Pathological dissociation is linked to swift cognitive switching, a trait potentially explained by childhood trauma. This suggests swift switching may be a cognitive marker for dissociation.

Area of Science:

  • Cognitive Psychology
  • Psychiatry
  • Neuroscience

Background:

  • Non-clinical dissociators exhibit rapid cognitive switching, alongside atypical updating and inhibition.
  • The role of swift switching as a cognitive endophenotype, particularly its link to trauma and pathological dissociation, remains unclear.

Purpose of the Study:

  • To investigate the hypothesis that pathological dissociation is associated with swift switching.
  • To determine if traumatization mediates the relationship between pathological dissociation and swift switching.

Main Methods:

  • Recruited unspecified acute psychiatric patients.
  • Administered behavioral measures of intellectual function and executive functions (updating, switching, inhibition).
  • Utilized standardized scales for pathological dissociation and traumatization assessment.

Main Results:

  • Inpatients with higher pathological dissociation scores showed superior switching and updating abilities.
  • Switching, not updating, remained a significant predictor of pathological dissociation when controlling for other executive functions and demographics.
  • The association between pathological dissociation and switching disappeared when childhood trauma effects were accounted for.

Conclusions:

  • Swift switching may serve as a cognitive endophenotype for pathological dissociation.
  • Childhood traumatization appears to be a key factor explaining the link between pathological dissociation and swift switching.
  • Findings support a trauma-related switching hypothesis in the context of pathological dissociation.
