Summary

This comprehensive lecture by Professor Zach Murphy covers CNS infections, focusing on meningitis, encephalitis, and brain abscesses. It begins with an overview of the routes of pathogen entry into the CNS, including hematogenous spread, contiguous spread from sinuses or ears, and retrograde axonal transport. The lecture then details the pathophysiology, clinical presentation, diagnostic approach, and treatment for each condition. Key topics include the interpretation of CSF findings, the importance of timely empiric antibiotics, the role of adjunctive dexamethasone, and the management of complications such as cerebral edema and herniation. The lecture emphasizes a systematic approach to localizing infections and narrowing differentials based on patient history and risk factors. It also highlights high-yield etiologies like HSV encephalitis and the need for prompt acyclovir initiation. The content is presented with clear illustrations and clinical pearls, making it valuable for medical students and practitioners.
