Aggressive Traits in People with Multiple Sclerosis-A Case-Control Study

Area of Science:

• Neuroimmunology
• Psychopathology
• Clinical Psychology

Background:

• Multiple sclerosis (MS) is a chronic neuroimmunological disease impacting young adults, often associated with psychiatric conditions like depression and anxiety.
• While psychosocial aspects of MS are studied, aggression in MS patients remains under-researched.
• Previous reports suggest significant aggression in up to 25% of MS patients.

Purpose of the Study:

• To assess aggressiveness in patients with multiple sclerosis (MS).
• To compare the levels of aggression in MS patients with matched healthy control subjects.

Main Methods:

• A cohort of 24 MS patients and 24 gender-, age-, and socioeconomic-matched healthy controls participated.
• Patients with moderate to severe disability, anxiety, or depression were excluded from the study.
• Aggressive trait was evaluated using a validated assessment tool.

Main Results:

• The study revealed a very low level of aggressive tendency in multiple sclerosis (MS) patients.
• Aggressiveness in MS patients was found to be significantly lower when compared to the control group.

Conclusions:

• The findings do not corroborate previous research indicating high aggression levels in MS patients.
• The exclusion criteria, particularly for patients with moderate/severe disability or psychiatric comorbidities, might have influenced the observed results.
