Investigating Mood and Cognition in People with Multiple Sclerosis: A Prospective Study Protocol

Area of Science:

• Neurology
• Neuroimmunology
• Psychiatry

Background:

• Multiple sclerosis (MS) is a prevalent neurological disorder affecting one million Americans.
• Depression impacts up to 50% of individuals with MS, but its underlying mechanisms are poorly understood.
• Previous research on depression and white matter variability often excludes patients with medical comorbidities like MS.

Purpose of the Study:

• To investigate the relationship between brain network disruption and depression in patients with MS.
• To explore white matter lesions as a potential predictor of depressive symptoms in MS.
• To utilize MS as a model to understand depression in the context of intracranial disease.

Main Methods:

• Recruit 250 participants diagnosed with multiple sclerosis.
• Conduct comprehensive structured clinical and cognitive assessments.
• Prospectively evaluate the burden of white matter lesions as a predictor of depressive symptoms.

Main Results:

• Analysis of clinical and cognitive data in relation to white matter lesion burden is ongoing.
• The study aims to identify specific patterns of white matter disruption associated with depression in MS.
• Results will quantify the impact of MS pathology on depressive symptoms.

Conclusions:

• Findings are expected to elucidate the neurobiological underpinnings of depression in MS.
• This research may inform the development of targeted interventions for depression in MS patients.
• The study will contribute novel insights into the complex interplay between neurological disease and mental health.
