Definitions

Any encephalitis that is restricted to the gray matter.

Examples

“First of all, in order⟳ to distinguish this from two other lesions which have⟳ been termed polioencephalitis inferior (progressive bulbar paralysis) and polioencephalitis superior (nuclear ophthalmoplegia), let⟳ us speak⟳ of this as polioencephalitis corticalis. What proof have⟳ we that there is such a condition? Anatomical proof, none; we are willing to concede, however, that some of the many cases of atrophy and sclerosis may have⟳ been due to this polioencephalitis, but it is unfortunate for Strümpell's theory that all of the autopsies made soon after the onset of the disease have⟳ shown other conditions, and not a polioencephalitis.”

“Before dismissing the subject of acute polioencephalitis it is necessary to devote a few paragraphs to the mention⟳ of a similar inflammatory process⟳ in other parts of the central nervous system.”

“The restriction of the inflammatory process⟳ to the gray matter⟳ in the polioencephalitis group was explained by the presumption that viruses are present⟳ mainly in the cell bodies of neurons, as they have⟳ an affinity for the nerve cells themselves: gangliocytotropism or neurocytotropism (Környey 1933)”

“Encephalitic processes are further subdivided into three main types: □ Polioencephalitis (Greek: polios, grey) is grey-matter predominant. □ Leukoencephalitis (Greek: leukos, white) is white-matter predominant. □ Panencephalitis (Greek: pan-, all) affects both grey and white matter⟳.”
