Brain hemispheric organization, anxiety, and psychoses

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Psychology

Background:

• Abnormalities in brain hemispheric organization are observed in various psychiatric conditions.
• The precise role of these hemispheric abnormalities in the pathogenesis of psychiatric disorders remains debated.
• Existing theoretical models offer diverse explanations for these observed phenomena.

Purpose of the Study:

• To review current understanding of brain hemispheric functioning.
• To discuss the involvement of hemispheric organization abnormalities in schizophrenia and anxiety disorders (panic disorder, obsessive-compulsive disorder).
• To propose a developmental perspective explaining these abnormalities.

Main Methods:

• Literature review of current concepts in hemispheric functioning.
• Synthesis of data on brain hemispheric organization in schizophrenia and anxiety disorders.
• Developmental framework analysis.

Main Results:

• Hemispheric organization abnormalities are consistently reported in schizophrenia and certain anxiety disorders.
• The contribution of these abnormalities to the onset and progression of these disorders is complex and multifactorial.
• A developmental perspective provides a potential framework for understanding the origins of these abnormalities.

Conclusions:

• Brain hemispheric organization plays a significant role in the pathophysiology of schizophrenia and anxiety disorders.
• Further research integrating developmental trajectories is crucial for a comprehensive understanding.
• Understanding these developmental aspects may inform future therapeutic strategies.
