Encephalitis is an inflammation of the brain parenchyma, which can result from various etiologies including viral infections, bacterial infections, autoimmune processes, or underlying metabolic disorders. The condition manifests due to damage to the neural tissue, affecting cognitive function, motor skills, and behavior. Diagnosis typically involves clinical assessment, cerebrospinal fluid analysis, and imaging studies to determine the underlying cause and severity. Management strategies are multidisciplinary, focusing on identifying the causative agent, providing supportive care for symptoms, and administering targeted treatments to reduce inflammation and mitigate neurological damage.
