Diseases

Meniningoenphalitis

Back

Inflammation of the membranes of the brain and the adjoining cerebral tissue.

SYMPTOMS

Early meningitis symptoms may mimic the flu (influenza). Symptoms may develop over several hours or over a few days.
Possible signs and symptoms in anyone older than the age of 2 include:

Sudden high fever
Stiff neck
Severe headache that seems different than normal
Headache with nausea or vomiting
Confusion or difficulty concentrating
Seizures
Sleepiness or difficulty waking
Sensitivity to light
No appetite or thirst
Skin rash (sometimes, such as in meningococcal meningitis)

CAUSES

Viral infections are the most common cause of meningitis, followed by bacterial infections and, rarely, fungal infections. Because bacterial infections can be life-threatening, identifying the cause is essential.
