Cognitive, but not mood dysfunction develops in multiple sclerosis during 7 years of follow-up

Area of Science:

• Neurology
• Neuropsychology
• Psychiatry

Background:

• Multiple Sclerosis (MS) is a chronic neurological disease affecting the central nervous system.
• Psychological deficits, including depression and cognitive impairment, are common in MS patients.
• Understanding the long-term trajectory of these deficits in early, disability-free MS is crucial for patient management.

Purpose of the Study:

• To evaluate the long-term development of psychological deficits in disability-free, early multiple sclerosis (MS) patients.
• To compare the progression of physical and cognitive parameters, as well as depression scores, with healthy controls over seven years.

Main Methods:

• A longitudinal study design was employed.
• Twenty-seven female patients diagnosed with early-stage, disability-free MS were followed for seven years.
• Physical function, cognitive abilities, and depression scores were assessed and compared to a control group of healthy individuals.

Main Results:

• Significant deterioration in physical and cognitive parameters was observed in MS patients over the seven-year period.
• Depression scores did not show a significant increase or difference compared to controls.
• Self-assessed somatic complaints remained dissimilar between MS patients and the control group throughout the study.

Conclusions:

• While physical and cognitive functions decline in early MS, depression may not be directly linked to physical disease progression.
• Cognitive deficits appear to be more closely related to physical disease progression than depression in early MS.
• Further research is needed to understand the complex interplay between physical progression and psychological well-being in multiple sclerosis.
