This book covers topics related to viral and fungal infections of the central nervous system (CNS), with a multidisciplinary reach, discussing associated immunology, microbiological aspects, pathologies, timely management, and prevention. The book is structured into five broad sections. The first section provides the reader with valuable insights into the aetiologies and underlying pathophysiological mechanisms of neurological diseases, including host responses. It mentions all bacterial, fungal, parasitic, and viral causes of neuro-infections, along with rarer neuropathogenesis such as prions and mycoplasmas. The chapter also presents detailed epidemiology and prevalence of different CNS infections worldwide. It also reviews various infectious diseases that target the nervous system, such as focal lesions, meningitis, and neurological complications of venous sinus thrombosis. The next two sections delve deep into pathogen-specific diseases of the CNS, namely the viruses and fungi associated with neuro-infections. It mentions detailed excerpts on encephalitic viruses, long-term consequences of neurotropic viruses, mycological neuroinfectious, and even the emerging, less talked of viruses and fungi causing neurological disease. Topics such as principles of vigorous antifungal therapy and surgeries are also discussed in the chapter. The fourth section gives an insight on prospects for efficiently diagnosing and managing viral and fungal CNS infections, to tackle associated morbidities. Features that are often less documented, yet of considerable interest in current times, such as the role of immunosuppression in neurological infections and newer microbiological diagnostic strategies are covered. The last section uniquely provides clinicians with relatable case scenarios. Real case descriptions are included, such as cases of fungal meningitis and other difficult-to-diagnose infections produced by viruses. This book serves as a guide for neurologists, medical microbiologists, and clinical practitioners who deal with patients suspected of neurological infection.
