What are CNS Infections?

The Central Nervous System (CNS) comprises of the brain, spinal cord and related membranes. Usually, CNS is well-secured against infections by tough, protective membranes. But under some circumstances, bacteria gain access to areas of the CNS and results in abscesses as well as empyemas (accumulation of pus). This exerts pressure on the brain or spinal cord and can even damage the nervous system tissue, possibly permanently. It is important to treat CNS infections as otherwise they can prove to be fatal.
