Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

401
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

54
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...

Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

36
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...

Psychosis and Antipsychotic Drugs: Overview

171
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Psychological and Sociocultural Causes of Schizophrenia

49
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...

Schizophrenia

59
Schizophrenia, a term introduced by Swiss psychiatrist Eugen Bleuler in 1911, describes a severe psychological disorder marked by profound disruptions in attention, thought processes, language, emotion, and interpersonal relationships. The core feature of schizophrenia is psychosis — a state characterized by a fundamental detachment from reality. This disconnection manifests through distorted logic, impaired perception, and atypical behavior, severely affecting the lives of those...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Complexity Science

Background:

  • Psychotic disorders present diagnostic challenges.
  • Resting-state fMRI spatiotemporal complexity aids in identifying brain activity irregularities.
  • Traditional correlation analyses have limitations in capturing global brain connectivity.

Purpose of the Study:

  • To explore higher-order interactions and multiscale intrinsic connectivity networks (ICNs) in the psychotic brain.
  • To investigate disruptions in brain network connectivity using information-theoretic metrics.
  • To assess the integration and segregation of topological information in psychosis.

Main Methods:

  • Utilized information-theoretic metrics to analyze global brain connectivity.
  • Estimated brain network connectivity using redundancy and synergy measures.
  • Explored higher-order topological functional connectivity in resting-state fMRI data.

Main Results:

  • The psychotic brain exhibits spatial and temporal randomness.
  • A disruption in the balance of redundant and synergistic information, termed 'brainquake,' was observed.
  • Profound disruptions in brain information integration were identified across cortical and subcortical ICNs.

Conclusions:

  • Psychosis significantly alters brain complexity and organizational states.
  • Aberrant information interactions impact sensorimotor, visual, temporal, default mode, and fronto-parietal networks.
  • The findings highlight severe impacts on critical brain networks in psychotic states.
