PathogenesisBacteria log nervous as follows (Hockenberry, & Wilson 2009: 998).1. Infection via the bloodstream.(hematogenous spread) with the source of infection in another part of the body, such as respiratory infections in the bloodstream and bacteria through logging nerve.2. From spreading from adjacent organs, such as with chronic inflammation of middle ear with inflammation of the bone มาสตอยด์ (mastoiditis). Or an infection of the big vein in the dura from infection in the face, nose, or caused by the rupture of Meningocele.3. Infected directly from contamination (direct contamination) from a serious accident caused broken skulls Or fractured bones at the base of the skull, causing the aperture with the cerebrospinal fluid flow out through the nose or ears. Or by the hand of the careless caused contamination such asLumbar puncture surgery.When the bacteria into the channel under the subarachnoid space is an inflammation the skin outer rim. Not if the infection may spread quickly. Since the system against pathogens in the channel under the arachnoid is low, make the skin area of brain inflammation swelling. Then a vasculitis Cerebral vasculitis lead to blockage of blood vessels and the lack of blood ไปเลี้ย brain, brain dead. Infraction also inflammation that occurs can also spread to the spinal cord to fester. The accumulation of pus resulted in blocking the passage of the cerebrospinal fluid. The high intracranial pressure. The occurrence of edema and intracranial Hypopituitary gland increased secretion of antidiuretic hormone promoting brain swelling. And death.A case of infection of tuberculosis. Which is often spread from pulmonary infection will build a tubercle (Tubercle) in brain tissue, and then tubercle in the wrong of the brain will break out. The tuberculosis infection into the spinal fluid. Part of the infection may enter the cerebrospinal fluid from inflammation. I choroid plexus or into the membrane directly on the brain blood stream. Tuberculosis infection in the cerebrospinal fluid is gradually causing inflammation.
