Summary
Central Nervous System Tuberculosis (CNS-TB) research is growing, particularly in India and China. International collaborations boost research impact, but many low-income countries need more focus on CNS-TB.
Area of Science:
- Bibliometrics
- Public Health
- Infectious Diseases
Background:
- Central Nervous System Tuberculosis (CNS-TB) presents a significant global health challenge.
- Existing research on CNS-TB lacks a comprehensive overview and mapping.
- High morbidity and mortality rates underscore the urgency of CNS-TB research.
Purpose of the Study:
- To provide a current and comprehensive overview of the CNS-TB research landscape.
- To analyze the intellectual and social structure of CNS-TB publications.
- To identify geographical disparities in CNS-TB scientific production and research focus.
Main Methods:
- Bibliometric analysis of 2130 CNS-TB articles from Web of Science (2000-2022).
- Descriptive statistics and data visualization using R, R-bibliometrix, and VOSViewer.
- Evaluation of publication trends, international collaborations, and geographical distribution.
Main Results:
- Annual publication output increased by 6.88%, led by India and China.
- International collaborations accounted for 16.44% of publications and 11 of the top 15 cited papers.
- Significant discrepancies exist between CNS-TB research output and TB incidence in many low- and middle-income countries.
Conclusions:
- CNS-TB research is expanding, driven by economic growth and funding in countries like China and India.
- International collaborations enhance the impact and accessibility of CNS-TB research.
- Disparities in research necessitate increased focus on CNS-TB in underrepresented, high-burden regions.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
