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...
Dark Triad and Person Perception01:29

Dark Triad and Person Perception

Person perception is influenced by both external behaviors and the observer’s internal characteristics, including personality traits. Individuals with dark personality traits, comprising psychopathy, Machiavellianism, and narcissism — collectively known as the dark triad – exhibit manipulative and exploitative tendencies in social contexts. These traits affect how they perceive others and how they are perceived.The Role of Dark Personality Traits in Person PerceptionBlack et al. (2014) explored...

Summary

Healthy individuals with high psychotic traits show altered brain white matter connectivity, particularly in the left arcuate fasciculus. Lower psychotic traits correlate with different connectivity patterns, suggesting brain asymmetry is linked to these traits.

Area of Science:

  • Neuroscience
  • Psychology
  • Brain Imaging

Background:

  • Psychotic personality traits are observed in healthy individuals.
  • Understanding the neurobiological underpinnings of these traits is crucial.
  • Previous studies suggest links between brain structure and psychotic disorders.

Purpose of the Study:

  • To investigate the relationship between white matter brain connectivity and psychotic personality traits in healthy subjects.
  • To identify specific white matter tracts associated with varying levels of psychotic traits.

Main Methods:

  • Utilized Diffusion Tensor Imaging (DTI) to assess fractional anisotropy (FA) in healthy controls.
  • Administered the MMPI-2 to assess and dichotomize participants into high- and low-psychotic trait groups.
  • Employed a voxelwise approach to compare FA values between the two groups.

Main Results:

  • The high-psychotic group exhibited higher FA in the left arcuate fasciculus.
  • The low-psychotic group showed significantly higher FA in the corpus callosum, right arcuate fasciculus, and fronto-parietal fibers.
  • These findings indicate distinct patterns of white matter connectivity related to psychotic traits.

Conclusions:

  • Psychotic personality traits are associated with altered regional brain white matter connectivity.
  • Results suggest a potential role for brain asymmetry in the manifestation of psychotic traits.
  • Findings align with neuroimaging studies of schizophrenia spectrum disorders.
