A severe and sometimes deadly inflammation of the brain that can be caused by a number of different viruses.

An acute inflammatory process affecting the brain parenchyma.

An inflammatory process affecting the brain parenchyma. Causes include viral infections and less frequently bacterial infections, toxins, and immune-mediated processes.

Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever. Severe cases need immediate treatment. Symptoms of severe cases include Severe headache; Sudden fever; Drowsiness; Vomiting; Confusion; Seizures. In babies, additional symptoms may include constant crying, poor feeding, body stiffness, and bulging in the soft spots of the skull. Severe cases may require a stay in the hospital. Treatments include oral and intravenous (IV) medicines to reduce inflammation and treat infection. Patients with breathing difficulties may need artificial respiration. Some people may need physical, speech, and occupational therapy once the illness is under control. NIH: National Institute of Neurological Disorders and Stroke

Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections are a relatively frequent cause of this condition.

Encephalitis is inflammation of the parenchyma of the brain, resulting from direct viral invasion. Acute disseminated encephalomyelitis is brain and spinal cord inflammation caused by a hypersensitivity reaction to a virus or another foreign protein. Both disorders are usually triggered by viruses. Symptoms include fever, headache, and...

Encephalitis, an inflammation of the brain parenchyma, presents as diffuse and/or focal neuropsychological dysfunction. Although it primarily involves the brain, the meninges are frequently involved (meningoencephalitis).

Encephalitis (en-sef-uh-LIE-tis) is inflammation of the brain. There are several causes, but the most common is a viral infection.

Encephalitis is defined as inflammation of the brain parenchyma associated with neurologic dysfunction such as altered state of consciousness, seizures, personality changes, cranial nerve palsies, speech problems, and motor and sensory deficits. It is the result of direct inflammation of the brain tissue, as opposed to the inflammation...

Encephalitis, from Greek enkephalos ("brain") and itis ("inflammation"), inflammation of the brain. Inflammation affecting the brain may also involve adjoining structures; encephalomyelitis is inflammation of the brain and spinal cord, and meningoencephalitis is inflammation of the brain and...
