Orbitofrontal sulcal patterns in catatonia

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Neuroscience

Background:

• Catatonia is a psychomotor syndrome linked to neurodevelopmental disorders, particularly schizophrenia.
• The orbitofrontal cortex (OFC) is implicated in catatonia, showing morphological variations like H-shaped sulcal patterns (Types I, II, III).
• OFC sulcal patterns Types II and III are risk factors for schizophrenia; however, their role in catatonia remains unstudied.

Purpose of the Study:

• To investigate the association between orbitofrontal cortex (OFC) sulcal patterns and catatonia.
• To explore the neurodevelopmental underpinnings of catatonia by examining OFC morphology.

Main Methods:

• Retrospective analysis of OFC sulcal patterns.
• Comparison of schizophrenia patients with catatonia (N=58), schizophrenia patients without catatonia (N=65), and healthy controls (N=82).

Main Results:

• Significant group differences in OFC sulcal patterns were observed in both left and right hemispheres.
• Catatonia patients showed a higher prevalence of Type III and lower prevalence of Type I patterns compared to healthy controls.
• Catatonia patients had more Type III patterns in the left hemisphere compared to schizophrenia patients without catatonia.

Conclusions:

• OFC sulcal patterns are indirect markers of early brain development.
• Findings support a neurodevelopmental origin for catatonia.
• The study may illuminate the pathophysiology of catatonia.
