Complications from mild West Nile virus infection are extremely rare. Complications from severe West Nile virus infection include permanent brain damage or muscle weakness (sometimes similar to polio), and death.

The West Nile virus is an arbovirus (meaning it is spread by mosquitos, ticks, or other arthropods) that can cause infections in animals and humans; in some cases, the infections can lead to fatal meningitis or encephalitis, which are inflammation...

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.

Encephalitis is an inflammation (irritation and swelling) of the brain, usually caused by infections. See also meningitis.
|
|
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.
|
|
An inflammatory disease of the brain caused by a virus that either has invaded the brain, or a virus appearing elsewhere in the body that has caused a sensitivity reaction in the brain. Encephalitis infects the brain tissue itself and has serious consequences.

Meningitis is a bacterial or non-bacterial infection that causes inflammation of the membranes covering the brain and spinal cord.

The following Clinical Topic Tour provides an overview of meningitis and was adapted from materials published by the National Institute of Neurological Disorders and Stroke, the National Cancer Institute, and the Centers for Disease Control and Prevention (CDC).

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 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).
|
|
An inflammation of the meninges, most often caused by infection. Meningitis is a potentially fatal inflammation of the meninges, membranes which encase the brain and spinal cord.

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.

Meningitis is a potentially fatal inflammation of the meninges, the thin, membranous covering of the brain and the spinal cord. Meningitis is most commonly caused by infection (by bacteria, viruses, or fungi), although it can also be caused by bleeding into the meninges, cancer , diseases of the immune system, and an inflammatory response to certain types of chemotherapy or other chemical agents.

Encephalitis is an acute inflammatory process that affects brain tissue and is almost always accompanied by inflammation of the adjacent meninges (tissues lining the brain). There are many types of encephalitis, most of which are caused by viral infections.

Paralysis is defined as complete loss of strength in an affected limb or muscle group. The chain of nerve cells that runs from the brain through the spinal cord out to the muscle is called the motor pathway.
