Predictive Value of the Third Ventricle Width for Neurological Status in Multiple Sclerosis

Area of Science:

• Neurology
• Neuroimaging
• Cognitive Neuroscience

Background:

• Third ventricle width (3VW) is a simple metric for assessing brain atrophy.
• Multiple Sclerosis (MS) is associated with cognitive impairment and physical disability.
• Understanding predictors of neurological decline in MS is crucial for patient management.

Purpose of the Study:

• To investigate the relationship between 3VW and cognitive function in MS patients.
• To assess the association of 3VW with disability, using the Expanded Disability Status Scale (EDSS).
• To identify predictors of cognitive impairment and disability in MS, adjusting for confounders.

Main Methods:

• Quantitative analysis of 3VW from 3D FLAIR MRI scans in 93 MS patients.
• Neuropsychological testing including Symbol Digit Modalities Test and memory assessments.
• Clinical and patient-reported outcome measures: EDSS, Hospital Anxiety and Depression Scale, Modified Fatigue Impact Scale (MFIS).

Main Results:

• Cognitive impairment was observed in 25% of MS patients.
• Both cognitive impairment and EDSS were significantly associated with increased 3VW.
• Age and 3VW were identified as the strongest predictors of cognitive impairment.
• 3VW, age, and disease duration predicted EDSS scores.

Conclusions:

• 3VW is a valuable predictor of neurological status in MS patients.
• 3VW effectively predicts cognitive impairment in MS, even after accounting for demographic and clinical factors.
• The findings highlight the utility of 3VW in assessing disease progression and cognitive decline in multiple sclerosis.
