Three Dimensional Brain Parameters of Multiple Sclerosis (MS) Patients

Area of Science:

• Neuroimaging
• Neurology
• Radiology

Background:

• Multiple sclerosis (MS) is a demyelinating disease affecting central nervous system gray and white matter.
• MS leads to axonal damage via inflammation and degeneration, with higher prevalence in females aged 20-40.
• Quantitative assessment of brain atrophy in MS patients is crucial for understanding disease progression.

Purpose of the Study:

• To quantitatively measure brain atrophy in multiple sclerosis (MS) patients.
• To compare brain parameters between MS patients and healthy controls across genders.
• To correlate observed brain changes with clinical disability in MS.

Main Methods:

• T2-weighted MRI scans were utilized for 40 MS patients (25 female, 15 male) with relapsing-remitting MS.
• Brain imaging data from MS patients were compared to sex-matched healthy controls.
• Poser criteria were used for clinical diagnosis of definite relapsing-remitting MS.

Main Results:

• MS patients exhibited significantly increased lateral and third ventricle width and cerebral sulci volume compared to controls.
• A considerable decrease in brain width, corpus callosum area, and total brain/cerebellum + brain stem volumes was observed in MS patients.
• Gender-specific differences in atrophy were not explicitly detailed but comparisons were sex-matched.

Conclusions:

• MS results in parenchymal destruction in the cortex and white matter, characterized by axonal degeneration and myelin loss.
• The measured brain atrophy in MS patients correlates with worsening disability.
• Quantitative MRI findings provide insights into the structural impact of MS on the brain.
