Headache in the course of multiple sclerosis: a prospective study

Area of Science:

• Neurology
• Immunology

Background:

• Multiple sclerosis (MS) is a leading immune-mediated inflammatory disease of the central nervous system (CNS).
• Early diagnosis and treatment are crucial for managing MS disability.
• Headache is often overlooked as an early MS symptom, frequently misdiagnosed as migraine.

Purpose of the Study:

• To investigate the prevalence and characteristics of headache in MS patients.
• To explore the relationship between headache and disease progression in MS.
• To highlight headache as a potential early indicator for MS diagnosis.

Main Methods:

• A prospective, multicenter study involving 150 patients with manifest MS (50 newly diagnosed, 100 long-term).
• Data collection via semi-structured interviews, medical history, neurological exams, and quality-of-life questionnaires.
• Assessment of headache occurrence in the past four weeks.

Main Results:

• Overall headache prevalence in MS patients was 67%.
• Prevalence reached 78% in patients at the time of initial MS symptom manifestation, particularly in clinically isolated syndrome (CIS).
• Headache sufferers were generally younger, had shorter disease duration, and less physical impairment; migraine-like headaches were common.

Conclusions:

• Headache is a significant early symptom of MS, especially in CIS patients.
• Young individuals experiencing frequent headaches should consider MRI for potential MS diagnosis.
• Prompt diagnosis and treatment initiated by recognizing headache as an early MS symptom can mitigate disease progression.
