Introduction: Chikungunya virus (CHIKV) and dengue fever have been reported for recent epidemics worldwide, with varied clinical involvement. Chikungunya was first reported to affect the nervous system in the 1960s. The clinical profile of dengue with multi-organ involvement is varied with reported involvement of the central nervous system in some.
Aim: The aim of this study was to study the frequency and pattern of neurological involvement in patients admitted with dengue and chikungunya in a tertiary care hospital.
Materials And Methods: Patients admitted with confirmed chikungunya and dengue were evaluated clinically and investigations were enrolled in the study. Patients with preexisting neurological issues, obvious metabolic, vascular, or septic causes for neurological involvement were excluded from the study.
Results: A total of 309 patients with chikungunya were included in the study. Out of these, 11 (3.56%) patients were found to have neurological involvement. The most common presentations were altered sensorium (100%) followed by headache (81.81%). The relative risk of mortality in patients with neurological involvement due to chikungunya was 7.96. A total of 443 patients with dengue fever were enrolled in the study. Out of these, 5 (1.10%) patients were found to have neurological involvement. The most common presentations were altered sensorium and headache (100%), followed by vomiting (80%). The relative risk of mortality in patients with neurological involvement due to dengue was 5.15.
Conclusion: The recent epidemic of chikungunya and dengue virus infections was associated with various neurological complications. Neurological involvement of chikungunya and dengue was identified to be a bad prognostic factor with significantly higher mortality.
Limitations: This is a single center study, involving only the patients admitted to the hospital. Furthermore, being an observational study, follow-up could not be done to look for neurological sequelae.

Chikungunya virus (CHIKV) is an emerging, mosquito-borne arthritic alphavirus increasingly associated with severe neurological sequelae and long-term morbidity. However, there is limited understanding of the crucial host components involved in CHIKV replicase assembly complex formation, and thus virus replication and virulence-determining factors, within the central nervous system (CNS). Furthermore, the majority of CHIKV CNS studies focus on neuronal infection, even though astrocytes represent the main cerebral target.

The COVID-19 outbreak, caused by the SARS-CoV-2 virus, was linked to significant neurological and psychiatric manifestations. This review examines the physiopathological mechanisms underlying these neuropsychiatric outcomes and discusses current management strategies. Primarily a respiratory disease, COVID-19 frequently leads to neurological issues, including cephalalgia and migraines, loss of sensory perception, cerebrovascular accidents, and neurological impairment such as encephalopathy.

Multidrug-resistant tuberculosis (MDR-TB) poses a significant global health threat, especially when it involves the central nervous system (CNS). Tuberculous meningitis (TBM), a severe manifestation of TB, is linked to high mortality rates and long-term neurological complications, further exacerbated by drug resistance and immune evasion mechanisms employed by Mycobacterium tuberculosis (Mtb). Although pulmonary TB remains the primary focus of research, MDR-TBM introduces unique challenges in diagnosis, treatment, and patient outcomes.

Methanol is a widely used industrial and household alcohol that poses significant health risks upon exposure. Despite its extensive use, methanol poisoning remains a critical public health concern globally, often resulting from accidental or intentional ingestion and outbreaks linked to contaminated beverages. Methanol toxicity stems from its metabolic conversion to formaldehyde and formic acid, leading to severe metabolic acidosis and multiorgan damage, including profound CNS effects and visual impairments.
