Neurobrucellosis: Brief Review

Area of Science:

• Infectious Diseases
• Neurology
• Bacteriology

Background:

• Brucella are Gram-negative bacteria, with five species pathogenic to humans.
• Transmission occurs through direct contact with infected animals.
• Older individuals face a higher risk of neurological complications from brucellosis.

Purpose of the Study:

• To review the epidemiology, clinical manifestations, diagnosis, imaging, and treatment of neurobrucellosis.
• To inform neurologists about this global health concern.

Main Methods:

• Review of existing literature on neurobrucellosis.
• Analysis of diagnostic criteria including CSF analysis and neuroimaging.
• Evaluation of treatment strategies and prognostic factors.

Main Results:

• Neurobrucellosis can cause central nervous system damage through direct invasion or immune responses.
• Diagnostic criteria include suggestive symptoms, positive Brucella spp. in CSF, specific CSF analysis (high protein, low glucose, lymphocytosis), and characteristic imaging findings.
• Combined and multi-route therapies are more effective than monotherapy for Brucella eradication.

Conclusions:

• Neurobrucellosis is a global disease, prevalent in endemic regions.
• Neurologists must be knowledgeable about neurobrucellosis presentation, diagnosis, and management.
• Prognosis varies, with meningitis having a good outlook, while diffuse CNS involvement may lead to long-term issues.
