Central nervous system (CNS) viral infections are critical causes of morbidity and mortality in children; however, comprehensive data on etiology is lacking in developing countries such as Indonesia. To study the etiology of CNS infections in a pediatric population, 50 children admitted to two hospitals in Bandung, West Java, during 2017-2018 were enrolled in a CNS infection study. Cerebrospinal fluid and serum specimens were tested using molecular, serological, and virus isolation platforms for a number of viral and bacteriological agents. Causal pathogens were identified in 10 out of 50 (20%) and included cytomegalovirus (n = 4), Streptococcus pneumoniae (n = 2), tuberculosis (n = 2), Salmonella serotype Typhi (n = 1) and dengue virus (n = 1). Our study highlights the importance of using a wide range of molecular and serological detection methods to identify CNS pathogens, as well as the challenges of establishing the etiology of CNS infections in pediatric populations of countries with limited laboratory capacity.

Cognitive impairment and dementia, including Alzheimer's disease (AD), pose a global health crisis, necessitating non-invasive biomarkers for early detection. This review highlights the retina, an accessible extension of the central nervous system (CNS), as a window to cerebral pathology through structural, functional, and molecular alterations. By synthesizing interdisciplinary evidence, we identify retinal biomarkers as promising tools for early diagnosis and risk stratification.

Introduction: Primary central nervous system vasculitis (primary CNS vasculitis) is a rare inflammatory disorder that affects small-to-medium-sized cerebral vessels, often leading to recurrent strokes. Diagnosis is vague due to non-specific neurological symptoms. Imaging findings, cerebrospinal fluid (CSF) analysis and exclusion of systemic vasculitis are essential for diagnosis.

Background: Invasive central nervous system (CNS) aspergillosis is rare among human immunodeficiency virus (HIV)-positive patients due to preserved neutrophil function, despite significant CD4+ T-cell depletion. Diagnosis typically requires histopathologic confirmation, but polymerase chain reaction (PCR) testing has introduced new challenges due to its high sensitivity but limited specificity.
Case Presentation: We describe a newly diagnosed 43-year-old HIV-positive male with concurrent Hodgkin lymphoma who presented with progressive neurological decline and a ring-enhancing brain lesion.

Acute vestibular syndrome (AVS) is characterized by the sudden onset of dizziness or vertigo, accompanied by nausea, vomiting, gait instability, and nystagmus, lasting for more than 24 hours and often persisting for several days to weeks. Central AVS primarily involves central vestibular structures, such as the brainstem and cerebellum, and is most commonly caused by ischemic stroke in the posterior circulation. When acute posterior circulation infarction presents solely with isolated dizziness or vertigo, without other symptoms of central nervous system damage, it is often misdiagnosed as a peripheral vestibular disorder, this can lead to serious consequences.

Gliomas are the most common primary malignant tumors of the central nervous system (CNS), and despite progress in molecular diagnostics and targeted therapies, their prognosis remains poor. In recent years, immunotherapy has emerged as a promising treatment modality in cancer therapy. However, the inevitable immune evasion by tumor cells is a key barrier affecting therapeutic efficacy.
