[Structural MRI investigation in schizophrenia with optimised voxel-based morphometry--a pilot study]

Area of Science:

• Neuroimaging
• Psychiatric Disorders
• Brain Anatomy

Context:

• Structural magnetic resonance imaging (MRI) methods are increasingly vital in understanding psychiatric disorders.
• Voxel-based morphometry (VBM) is a widely utilized quantitative MRI technique for detecting regional brain differences.

Purpose:

• To compare brain tissue differences in gray matter, white matter, and cerebrospinal fluid between patients with schizophrenia and healthy controls using optimized VBM.
• To identify specific anatomical regions affected by tissue density changes in schizophrenia.

Summary:

• The study compared eight patients with schizophrenia and eight age-matched healthy subjects.
• Schizophrenia patients displayed reduced gray matter density in bilateral frontotemporal and insular regions, left parietal operculum, and calcarina.
• White matter density was decreased bilaterally in frontotemporal and insular regions, with additional involvement of the left precuneus and lingual gyrus.
• Increased cerebrospinal fluid spaces were observed in frontal regions and ventricles.

Impact:

• Findings align with previous neuroimaging studies on schizophrenia.
• Results corroborate known frontotemporal deficits in schizophrenia observed through neuropsychological assessments.
• Highlights the utility of VBM in characterizing the neuroanatomical underpinnings of schizophrenia.
