Biological Causes of Schizophrenia01:29

Biological Causes of Schizophrenia

375
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: Pathophysiology of Schizophrenia and Other Psychotic Disorders

1.7K
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...

Negative and Cognitive Symptoms of Schizophrenia

311
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Psychological and Sociocultural Causes of Schizophrenia

373
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

602
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...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

136
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Area of Science:

  • Neuroscience
  • Genetics
  • Systems Biology

Background:

  • Cognitive impairments are a key feature of schizophrenia.
  • A genetic overlap exists between schizophrenia and cognitive functioning in healthy individuals.
  • Identifying shared biological pathways is challenging due to complex genetic architectures.

Purpose of the Study:

  • To characterize the biological relatedness between schizophrenia and cognitive functioning using network medicine.
  • To identify overlapping biological pathways through protein-protein interactions of risk genes.
  • To pinpoint specific schizophrenia risk genes associated with cognitive performance for potential therapeutic targets.

Main Methods:

  • Utilized network-based methods and protein-protein interaction networks (interactome).
  • Applied network separation to assess the overlap between schizophrenia risk genes and cognition-associated genes.
  • Employed network propagation to identify schizophrenia risk genes proximal to cognition-associated genes.

Main Results:

  • Demonstrated a significant overlap in the protein interactome between schizophrenia risk genes and cognition-associated genes.
  • Identified 140 schizophrenia risk genes close to cognition-associated genes, with 54 in direct genetic overlap.
  • Found enrichment for pathways like long-term potentiation and Alzheimer's disease, involving neurotransmitter systems (glutamate, dopamine).

Conclusions:

  • Schizophrenia risk genes are biologically linked to cognitive functioning in the general population.
  • Specific schizophrenia risk genes near cognition-associated genes are promising targets for cognitive enhancement therapies.
  • Identified druggable genes with potential for developing novel treatments for cognitive deficits in schizophrenia.
