Typically, the infection is derived from elsewhere in the body – especially viral /bacterial infection that first starts in the sinuses, ears, and upper respiratory tract. In less common cases, other causes include autoimmune disorders, certain medications, and fungal infection.
Studies have shown that meningitis is relatively more common in the elderly (over age 55), young adults (especially those at the age between 15 and 25), and children (age 5 or younger). And it’s also thought that the effect of meningitis is more serious in people with autoimmune disease, chronic disease, or damaged spleen.
Cerebritis
It is inflammation of the brain. It can be triggered by inflammation or infection elsewhere in the body such as in the sinuses.
Brain absences
The sinus infection that spread to the brain may cause an abscess. This can be a consequence of when the infection causes swelling and inflammation in the brain.
The infected brain cells, dead bacteria, or white blood cells are accumulated in an area of the brain. Then this area is surrounded by tissues that create a mass (abscess).
