Viruses, bacteria, fungi, and parasites lead to neuroinfectious disorders, which pose a serious global health risk because they are extremely morbid and fatal in addition to having long-term neurological consequences. These viruses exploit the innate vulnerabilities of the central nervous system (CNS), including immunological privilege or the blood-brain barrier, to infect patients through hematogenous spread, neuronal pathways, or direct invasion. Microorganisms induce neuroinflammation, demyelination, neurotransmission changes, and neuronal death to cause both acute diseases, such as meningitis and encephalitis, and chronic neurodegenerative outcomes after entry into the brain. Its spectrum of these clinical manifestations is acute, dangerous infections, post-infectious autoimmune diseases, and persistent intellectual disability. Innovation in neuroimaging, cerebrospinal fluid, molecular diagnostics, and biosensor technologies has enhanced detection, and treatment involves antibiotic medication, immunomodulation, and supportive care. The preventive strategies, like vaccination and infection control, are also essential. The ongoing studies on the new treatment and regeneration strategies are encouraging in that they can be used in the removal of the burden of neuroinfectious diseases across the world.
