Study Notes
Neurological Infections
- Infections of the central nervous system (CNS) are medical emergencies that can be life-threatening and have severe sequelae, such as coma, decreased mental capacity, seizure, and persistent neurological deficit.
Anatomy of Neurological System
- The central nervous system (CNS) consists of the brain and spinal cord.
- The peripheral nervous system (PNS) includes peripheral nerves.
- The meninges, brain parenchyma, and subarachnoid space are also part of the CNS.
Types of CNS Infections
