Tuberculosis of the Central Nervous System

Area of Science:

• Neurology
• Infectious Diseases
• Public Health

Background:

• Central nervous system tuberculosis (CNS TB) presents significant global morbidity and mortality, particularly in low- and middle-income countries.
• Diagnosis and treatment are complicated by multidrug-resistant strains, HIV/AIDS, and immune reconstitution inflammatory syndrome.

Purpose of the Study:

• To review the epidemiology, clinical features, diagnostic approaches (imaging, CSF testing), and treatment strategies for CNS TB.
• To illustrate key diagnostic and management principles through case presentations.

Main Methods:

• Review of current literature on CNS TB epidemiology, pathogenesis, diagnosis, and management.
• Analysis of recent advances in diagnostic assays and precision medicine.
• Case-based illustration of diagnostic and therapeutic challenges.

Main Results:

• Despite progress, CNS TB remains difficult to diagnose, necessitating a low threshold for empiric treatment.
• Newer diagnostic assays aim to expedite diagnosis and guide therapy selection.
• Genetic factors (e.g., LTA4H polymorphisms) are implicated in tuberculous meningitis inflammation.

Conclusions:

• CNS TB requires prompt recognition and management, with a high index of suspicion.
• Advances in diagnostics and understanding of host-pathogen interactions are improving patient outcomes.
• Effective management necessitates a combination of timely antitubercular and anti-inflammatory therapies.
