The clinical picture of encephalitis

Depending on the etiology and characteristics of pathogenesis there is a great variety of symptoms and types of flow encephalitis.
Encephalitides process can be one of the manifestations of almost any infectious diseases (secondary encephalitis). Clinical symptoms of encephalitis nosological forms (primary encephalitis), as a rule, are not limited encephalitides syndrome and may include symptoms of the meninges (meningoencephalitis), spinal cord (encephalomyelitis), roots (meningoencephalopolyradiculoneuritis) and visceral organs, such as upper respiratory tract (gruppoide form of encephalitis).
Downstream there are acute and chronic encephalitis. However, for some forms of encephalitis one or another type of flow characterizes only the phase of the disease. So, when the epidemic and less with tick-borne encephalitis possible transition from the acute phase of the disease in chronic. In other cases, encephalitis can occur by type subclinical infection without acute phase with further progressive chronic course.
For viral encephalitis (both primary and secondary) is characterized by acute. Chronic stage or primary chronic course with certainty established only if the epidemic and tick-borne encephalitis.
Infectious-allergic encephalitis secondary when the kollagenozov characterized by chronic course, but with occasional relapses.
In recent years it has attracted the attention of a kind of chronic and subacute encephalitis the progressing described under different names: inclusiony encephalitis Dawson, panencephalitis Pete-Doering, subacute sclerosing leukoencephalitis van Bogart, hyperkinetic subacute progressive encephalitis (, Uzunov, S. Bojinov, I. Georgiev) and other Etiology of these diseases is unknown, hence, their nosology still cannot be determined.

Primary encephalitis

Allergic encephalitis

The range of diseases that are included in this group are not precisely defined. Undoubtedly, this can include postvaccinal encephalitis, encephalitis after the introduction of serum drugs - the so-called sanogenetic encephalitides (Pete), as well as close to them in the pathogenesis encephalitides reactions in anaphylaxis (idiosyncrasies) to various food and other substances of protein and non-protein nature. On the mechanism of development of this group could include the so-called infectious-allergic encephalitis occurring at the background of the General absence of organism with focal infections, in particular rheumatic encephalitides.

Secondary encephalitis
