The cause is often not clear. It may be due to a virus, but it can also arise from bacterial infection, head injury, extreme stress, an allergy, or as a reaction to medication. 30% of affected people had a common cold prior to developing the disease. [1] Either bacterial or viral labyrinthitis can cause a permanent hearing loss in rare cases. [7]
Dizziness is a common medical complaint, affecting 20–30% of persons. [4] Dizziness is broken down into four main subtypes: vertigo (~25–50%), disequilibrium (less than ~15%), presyncope (less than ~15%), and nonspecific dizziness (~10%). [5] Vertigo is the sensation of spinning or having one's surroundings spin about them. Many people find ...
If the ataxia is due to bleeding, surgery may be needed. For a stroke, medication to thin the blood can be given. Infections may need to be treated with antibiotics. Steroids may be needed for swelling (inflammation) of the cerebellum (such as from multiple sclerosis). Cerebellar ataxia caused by a recent viral infection may not need treatment.
Viruses that cause viral encephalitis first infect the body and replicate outside of the central nervous system (CNS). Thereafter, most reach the spinal cord and brain via the circulatory system. Exceptions to this include herpesviruses and the rabies virus, which travel from nerve endings to the CNS.
Central vertigo is less common and is caused by a problem in the brain. It might be in the brain stem. It might be in the brain stem. It could also be in the back part of the brain, called the ...
The majority of cases of limbic encephalitis are associated with a tumor (diagnosed or undiagnosed). In cases caused by tumor, recovery can only occur following complete removal of the tumor, which is not always possible. Limbic encephalitis is classified according to the auto-antibody that causes the disease. The most common types are:
The data seems to point to Staphylococci as the leading bacterial cause of infection leading to ventriculitis being present in about 90% of cases, [6] but generally, what is of more concern is the way the infection entered the ventricles. The brain in its natural state is very protected from infection. The blood–brain barrier serves to keep ...
Cerebritis is the inflammation of the cerebrum, which performs a number of important functions, such as memory and speech.It is also defined as a purulent nonencapsulated parenchymal infection of the brain which is characterized by nonspecific features on CT scans (ill-defined low density area with peripheral enhancement) and cannot reliably be distinguished from neoplasms.
