Complications from mild West Nile virus infection are extremely rare.Complications from severe West Nile virus infection include:.Permanent brain damage Permanent muscle weakness(sometimes similar to polio) Death.

|
The prognosis for persons with West Nile virus infection is quite favorable in patients that are young and in otherwise good health. Older persons and patients with health complications can have a poorer prognosis.

Encephalitis is irritation and swelling(inflammation) of the brain, usually due to infections.Encephalitis is most often caused by a viral infection. Many types of viruses may cause it.
|
|
Although the word meningitis suggests an inflammation of the meninges only, there is always some involvement of the most superficial parts of the brain that are contiguous to the meninges. Often there are also alterations in the flow of cerebrospinal fluid (CSF).

|
Encephalitis is an inflammation of the brain, usually caused by a direct viral infection or a hypersensitivity reaction to a virus or foreign protein. Brain inflammation caused by a bacterial infection is sometimes called cerebritis.

Encephalitis infects the brain tissue itself and has serious consequences.Among the many forms of encephalitis are those that occur seasonally, those that affect animals, and a form that is carried by a mosquito. Viruses that have been directly im...

Meningitis is swelling and irritation(inflammation) of the membranes covering the brain and spinal cord. This inflammation causes changes in the cerebrospinal fluid(CSF) that surrounds the brain and spinal cord.The most common causes of meningitis...

Meningitis is a serious inflammation of the meninges, the membranes(lining) that surround the brain and spinal cord. It can be of bacterial, viral, or fungal origin.Meningitis is usually the result of a viral or bacterial infection.
|
|
Meningitis is the most common serious manifestation of infection of the central nervous system (CNS). Inflammatory involvement of the subarachnoid space with meningeal irritation leads to the classic triad of headache, fever and meningism, and to a pleocytosis in the cerebrospinal fluid (CSF).

Bacterial meningitis Epidemiology and microbiology: the overall annual incidence of bacterial meningitis is about 2?3/100,000, with peaks of incidence in infants and adolescents. Integration of vaccines into the UK vaccination programme against Haemophilus influenzae type b (Hib) and more recently against group C meningococccus has led to a marked decline in cases of Hib and Group C meningococcal meningitis and has significantly reduced the overall incidence of bacterial meningitis.

General paresis is an impairment of mental function caused by damage to the brain from untreated syphilis.General paresis is one form of neurosyphilis. Today it is very rare.The syphilis infection damages the nerves of the brain.

Traumatic brain injury(TBI) is the result of physical trauma to the head causing damage to the brain. This damage can be focal, or restricted to a single area of the brain, or diffuse, affecting more than one region of the brain.
