    This study found that manics had greater overall brain density in upper sections compared to schizophrenics. However, both groups showed similar patterns of interhemispheric density differences, suggesting distinct regional brain density variations.

    Area of Science:

    • Neuroimaging
    • Psychiatry
    • Radiology

    Background:

    • Schizophrenia and mania are distinct psychiatric disorders with complex neurobiological underpinnings.
    • Previous research suggests structural brain abnormalities in various psychiatric conditions, but direct comparisons of regional brain density between schizophrenia and mania are limited.

    Purpose of the Study:

    • To investigate regional brain density differences between young male patients diagnosed with schizophrenia and mania.
    • To determine if X-ray computed tomography (CT) can differentiate between these two patient groups based on brain density.

    Main Methods:

    • Regional brain density was measured using X-ray computed tomography (CT) in cohorts of young males diagnosed with schizophrenia and mania.
    • Analysis focused on interhemispheric density differences and overall density in specific upper brain sections.

    Main Results:

    • Both schizophrenic and manic groups exhibited similar patterns of interhemispheric brain density differences.
    • Manic patients demonstrated significantly greater overall brain density in the uppermost brain sections studied (16-24 mm above the lateral ventricles).

    Conclusions:

    • Regional brain density, particularly in upper brain sections, may offer a distinguishing biomarker between schizophrenia and mania.
    • These findings contribute to understanding the neuroanatomical variations associated with these distinct psychiatric disorders.
