Using a pediatric-focused lens, this review article briefly summarizes the presentation of several demyelinating and neuroinflammatory diseases using conventional magnetic resonance imaging (MRI) sequences, such as T1-weighted with and without an exogenous gadolinium-based contrast agent, T2-weighted, and fluid-attenuated inversion recovery (FLAIR). These conventional sequences exploit the intrinsic properties of tissue to provide a distinct signal contrast that is useful for evaluating disease features and monitoring treatment responses in patients by characterizing lesion involvement in the central nervous system and tracking temporal features with blood-brain barrier disruption. Illustrative examples are presented for pediatric-onset multiple sclerosis and neuroinflammatory diseases.

Acute encephalitis syndrome (AES) presents with the onset of fever, altered sensorium and/or seizures, known to be caused by various infectious and non-infectious aetiological agents, among which viruses are the commonest. The severity of AES prompts rapid diagnosis, which is not met by time-consuming conventional diagnostic techniques. In this study, archived cerebrospinal fluid samples of laboratory-confirmed viral AES, an acute infectious condition and Guillain-Barré Syndrome (GBS), a post-infectious, autoimmune condition was assessed for soluble membrane attack complex (sMAC) using ELISA.

Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Cuprizone-induced demyelination, wherein mice are fed a diet containing the copper chelator cuprizone, is a well-established model that replicates key features of demyelination and remyelination. However, the dose-response relationship of cuprizone is complex; high concentrations can induce toxicity, whereas low doses may fail to produce reliable demyelination across subjects.

Background And Objectives: Pediatric patients with acute disseminated encephalomyelitis (ADEM) are at risk of impaired brain growth, with long-term neuropsychiatric consequences. We previously reported transient expansions of cerebral ventricle volume (VV) in experimental autoimmune encephalomyelitis, which subsequently normalized. In this study, we investigated changes in VV in ADEM in relation to other brain structures and clinical outcomes.

Background: There are currently seven coronaviruses that can infect humans and the latest addition to these viruses is the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Infection by SARS-CoV-2 is known commonly as coronavirus disease 2019 (COVID-19). Aside from common manifestations of cough and fever, neurologic symptoms such as headache, disturbed consciousness, paresthesia, and seizures have also been seen.
