Longitudinal study of alexithymia and multiple sclerosis

Area of Science:

• Neurology
• Psychiatry
• Clinical Psychology

Background:

• Multiple sclerosis (MS) is a chronic neurological condition impacting cognitive and emotional well-being.
• Alexithymia, characterized by difficulty identifying and describing emotions, is frequently observed in MS patients.
• Understanding the longitudinal course of alexithymia and its relationship with comorbid anxiety and depression is crucial for patient management.

Purpose of the Study:

• To investigate the 5-year course of alexithymia in patients with multiple sclerosis.
• To examine the relationship between alexithymia, anxiety, and depression over time in this population.
• To identify specific components of alexithymia that may change or remain stable.

Main Methods:

• A cohort of 62 patients with multiple sclerosis was assessed over a 5-year period.
• Participants completed validated questionnaires measuring socio-demographic, medical, and psychological variables, including depression, anxiety, and alexithymia.
• Statistical analyses were performed to evaluate changes and correlations in emotional disorder symptoms.

Main Results:

• Emotional disorders, including alexithymia and anxiety, demonstrated stability over the 5-year study period in MS patients.
• A significant decrease in depression rates was observed, from 40% at baseline to 26% at follow-up.
• Difficulty identifying and describing feelings (two alexithymia dimensions) correlated with anxiety and depression; externally oriented thinking was independent and decreased over time.

Conclusions:

• Alexithymia is a persistent feature in multiple sclerosis patients, associated with heightened anxiety.
• The findings suggest that while depression may improve, alexithymia components and anxiety levels remain relatively stable.
• Externally oriented thinking, a facet of alexithymia, showed a notable reduction over 5 years, indicating potential for change in specific emotional processing styles.
