Primary Headache in Behçet's and Neuro-Behçet's Disease

Area of Science:

• Rheumatology
• Neurology
• Vasculitis Research

Background:

• Behçet's disease (BD) is a multisystem vasculitis affecting various organs.
• Neurological involvement (neuro-Behçet's disease, NBD) occurs in approximately 5% of BD patients.
• Headache is a common symptom in patients with Behçet's disease.

Purpose of the Study:

• To compare primary headache onset and types in BD patients with and without neurological involvement.
• To investigate differences in headache presentation between neuro-Behçet's disease (NBD) and BD without neurological involvement (BWoNI).

Main Methods:

• A comparative study evaluating 136 consecutive Behçet's disease patients.
• Patients were categorized into two groups: BWoNI (n=98) and NBD (n=38).
• Analysis focused on the timing (before/after BD onset) and characteristics of primary headaches.

Main Results:

• Primary headaches occurred more frequently after BD onset than before in both BWoNI (48.1% vs. 27.6%) and NBD (34.2% vs. 10.5%) groups.
• The pattern of headache onset (more frequent after BD onset) was consistent across both groups and overall.
• The types of primary headaches were comparable between BWoNI and NBD patients.

Conclusions:

• Primary headaches in Behçet's disease patients predominantly manifest after the disease onset.
• Headache characteristics do not significantly differ between BD patients with and without neurological involvement.
• Findings suggest headache is a common feature of BD, irrespective of neurological complications.
