What is Neuro-Behçet Disease?

Neuro-Behçet disease (NBD) is the central nervous system involvement of Behçet disease, an autoinflammatory vasculitis with worldwide distribution but the highest prevalence along the Silk Road including Turkey.

Two main forms are recognized — parenchymal NBD with brainstem, hemispheric, or spinal cord lesions; and non-parenchymal NBD with cerebral venous sinus thrombosis or large arterial involvement.

Diagnosis combines criteria for Behçet disease (oral ulcers, genital ulcers, skin lesions, ocular disease, pathergy) with characteristic MRI findings, cerebrospinal fluid analysis, and exclusion of mimics.

Symptoms

Brainstem syndromes with diplopia, dysarthria, ataxia, and cranial neuropathies
Hemispheric symptoms with hemiparesis, sensory loss, and cognitive change
Spinal cord involvement with paraparesis, sensory level, and bowel-bladder dysfunction
Headache, papilledema, and visual disturbance from cerebral venous sinus thrombosis
Recurrent oral and genital ulcers, skin lesions, and uveitis indicating Behçet disease
Behavioral and psychiatric changes in chronic progressive disease

Risk Factors

HLA-B51 positivity
Male sex (more severe phenotype)
Onset in the third or fourth decade
Family history of Behçet disease
Country of origin along the Silk Road

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • New brainstem or spinal cord syndrome in a patient with mucocutaneous ulcers
  • Severe headache or visual changes with known Behçet disease — investigate for cerebral venous sinus thrombosis
  • Recurrent oral and genital ulcers with neurological complaints
  • Suspected vasculitis-associated neurological event

Treatment Methods

01
Acute parenchymal NBD: high-dose intravenous corticosteroids followed by gradual oral tapering
02
Long-term immunosuppression with azathioprine, methotrexate, mycophenolate, or biologics (TNF inhibitors)
03
Cerebral venous sinus thrombosis: corticosteroids combined with anticoagulation
04
Avoidance of cyclosporine in NBD due to potential neurotoxicity
05
Multidisciplinary follow-up with rheumatology, neurology, and ophthalmology and rehabilitation in chronic deficits
