Behçet's syndrome and the nervous system

Area of Science:

• Neurology
• Immunology
• Vascular Medicine

Background:

• Behçet's syndrome (BS) is a rare, multi-system inflammatory disorder of unknown origin.
• Neurological involvement occurs in a subset of patients, often presenting with acute neurological deficits.
• BS is a differential diagnosis for conditions like multiple sclerosis and stroke in young adults.

Purpose of the Study:

• To review the spectrum of neurological involvement in Behçet's syndrome.
• To highlight recent clinical concepts and ethiopathogenetic findings related to neuro-Behçet's disease.

Main Methods:

• This is a review article, synthesizing existing clinical and imaging evidence.
• No new experimental data were generated.

Main Results:

• Neurological involvement in BS is heterogeneous, with two main forms identified: vascular-inflammatory CNS disease and cerebral venous sinus thrombosis with intracranial hypertension.
• The vascular-inflammatory form often presents with focal or multifocal parenchymal lesions.
• Isolated cerebral venous sinus thrombosis typically has fewer symptoms and a better prognosis.

Conclusions:

• The nervous system involvement in BS is diverse, encompassing vascular, inflammatory, and thrombotic processes.
• The precise factors driving neurological involvement remain unclear.
• Further understanding of the neurological spectrum of BS is crucial for improved patient management.
