Vasculitis is a complication of several infectious diseases affecting the central nervous system, which may result in ischemic and/or hemorrhagic stroke, transient ischemic attack, and aneurysm formation. Infectious agents may directly infect the endothelium causing vasculitis or indirectly affect the vessel wall through an immunological cascade. Clinical manifestations usually overlap with those of noninfectious vascular diseases, making diagnosis challenging. Neuroimaging enables the identification of inflammatory changes in intracranial vasculitis. In this article, we review the imaging features of infectious vasculitis of bacterial, viral, fungal and parasitic causes.

Background: People living with HIV (PLWH), especially immunological non-responders (INRs), may experience adverse neurologic events. However, the extent of neurological impairment in INRs remains uncertain. This study evaluates brain structure and function, immune dysregulation, and peripheral immunomarkers in INRs and immunological responders (IRs) among PLWH, classified according to immunological response criteria, within a clinical research setting.

Neurosyphilis-induced dementia represents a severe manifestation of tertiary syphilis, characterized by cognitive and neuropsychiatric impairments. This condition arises from the progression of syphilis to the central nervous system, where the spirochete causes damage through invasion, chronic inflammation, and neurodegeneration. The pathophysiology involves chronic inflammatory responses, direct bacterial damage, and proteinopathies.

Background And Objectives: This study aims to report the clinical, biological, and imaging features of cross-sectional study of neurosyphilis patients with leptomeningeal enhancement of spinal cord. Here, 51 neurosyphilis patients with leptomeningeal enhancement of spinal cord positivity are described, offering a promise in terms of early diagnosis, thereby enabling timely detection and treatment.
Methods: We retrospectively included all neurosyphilis patients enrolled in this study from December 2019 to January 2024.

Persistent cognitive fatigue (CF) is the most reported symptom in Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), but little is known about its underlying neural basis. This pilot study examined fMRI brain activation patterns during a fatiguing task in those with and without PASC. We hypothesized that individuals with PASC would show changes in CF-related brain activation within fatigue network.
