Abstract

During the past decade (and beyond), neurologists have become aware of the emergence, persistence, and consequences of some familiar and new infections affecting the nervous system. Even among the familiar CNS infections, such as herpes virus, polyoma virus/JC, influenza, arbovirus, and hepatitis, challenges remain in developing effective antiviral treatments and treatments of postinfection sequelae. With the changing environment and increased global travel, arthropod vectors that mediate zoonotic disease transmission have spread unfamiliar viruses such as West Nile virus, dengue, chikungunya, equine encephalitis, and Zika, among others. Although the global health impact of these diseases has not risen to that of COVID-19 and HIV, it is likely to dramatically increase with continued spread of transmission vectors and the emergence of new zoonotic animal-to-human diseases mediated by those transmission vectors. Furthermore, specific virus-targeting treatments or effective vaccines for arboviral infections are not yet available, and this represents a major challenge in limiting the morbidity of these infections. By contrast, HIV-1, a disease that originated by direct transmission from nonhuman primates to humans (as early as the 1930s), after many years of intense study, is now targeted by highly specific and effective antiviral drugs that can limit the spread of infection and extend human life and health in all populations. Even with these dramatic therapeutic effects of suppressing HIV replication, neurologic dysfunction (primarily cognitive impairment) affects significant numbers of persons living with HIV. This emphasizes not only the importance of treating the underlying infection but also developing treatments for legacy effects of the initial infection even after antiviral therapy. Notably, the rapid emergence of SARS-CoV-2 infection was met with rapid implementation of highly effective and specific antiviral therapies. This resulted in early and dramatic lowering of the morbidity and mortality of SARS-CoV-2 infection. Nonetheless, the postinfectious complications of SARS-CoV-2 infection (long COVID) are now among the more costly consequences of emerging zoonotic infections worldwide. Developing new antiviral therapies that can penetrate the CNS, vaccines, and therapies that target host immune responses and metabolic dysfunction will be necessary for management of infectious and postinfectious complications of established and emerging infections.

期刊介绍: Neurology Neuroimmunology & Neuroinflammation is an official journal of the American Academy of Neurology. Neurology: Neuroimmunology & Neuroinflammation will be the premier peer-reviewed journal in neuroimmunology and neuroinflammation. This journal publishes rigorously peer-reviewed open-access reports of original research and in-depth reviews of topics in neuroimmunology & neuroinflammation, affecting the full range of neurologic diseases including (but not limited to) Alzheimer's disease, Parkinson's disease, ALS, tauopathy, and stroke; multiple sclerosis and NMO; inflammatory peripheral nerve and muscle disease, Guillain-Barré and myasthenia gravis; nervous system infection; paraneoplastic syndromes, noninfectious encephalitides and other antibody-mediated disorders; and psychiatric and neurodevelopmental disorders. Clinical trials, instructive case reports, and small case series will also be featured.
