Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders01:27

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

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 the...
Dissociative Disorders01:27

Dissociative Disorders

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.

Positive Symptoms Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

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 loosely...
Psychological and Sociocultural Causes of Schizophrenia01:29

Psychological and Sociocultural Causes of Schizophrenia

Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
Psychodynamic Therapy01:29

Psychodynamic Therapy

Psychodynamic therapies emphasize the exploration of unconscious processes and early childhood experiences as fundamental contributors to psychological difficulties. These therapies, deeply rooted in Freud's psychoanalytic theory, aim to uncover and resolve unconscious conflicts, granting individuals insights that promote emotional and behavioral healing. Contemporary psychodynamic approaches have evolved, integrating a broader range of influences and methodologies while still valuing the...

Area of Science:

  • Psychiatry
  • Phenomenology
  • Neuroscience

Background:

  • Mental disorders alter lived time and space experiences.
  • Schizophrenia spectrum disorders (SSD) feature microstructural disturbances in temporal synthesis and self/world disintegration.
  • Mood disorders (MOD) and SSD share macro-level shifts like altered time passage and social spatial difficulties.

Purpose of the Study:

  • To investigate the similarities and distinctions in time and space experiences between SSD and MOD.
  • To understand how shared experiences arise despite differing core disturbances.
  • To identify specific phenomenological markers differentiating these disorders.

Main Methods:

  • Phenomenological interviews using the Scale for Time and Space Experience in Psychosis (STEP) were conducted with 26 SSD and 26 MOD patients.
  • Group comparisons were made on total STEP scores, time and space subscales, and individual items.
  • The SSD group was further analyzed by subdividing into high and low temporospatial disturbance levels.

Main Results:

  • SSD is characterized by fragmented temporal experience, diminished synthesis, and altered anisotropy, alongside world, self, and body disintegration.
  • Shared experiences between MOD and SSD include altered time velocity, a shift from future to past/present orientation, and spatial issues related to distance and social interaction.
  • Analysis revealed commonalities across disorders and disturbances more specific to SSD.

Conclusions:

  • The study identified both shared and distinct alterations in time and space perception between SSD and MOD.
  • Findings underscore the unique microstructural temporal fragmentation in SSD.
  • Phenomenological assessment provides valuable insights into the subjective experience of these disorders.
