Baló's concentric sclerosis is a disease in which the white matter of the brain appears damaged in concentric layers, leaving the axis cylinder intact. [1] It was described by József Mátyás Baló who initially named it "leuko-encephalitis periaxialis concentrica" from the previous definition, [2] and it is currently considered one of the borderline forms of multiple sclerosis.
By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...

The name "multiple sclerosis" is short for multiple cerebro-spinal sclerosis, which refers to the numerous glial scars (or sclerae – essentially plaques or lesions) that develop on the white matter of the brain and spinal cord.
Unusual types of MS have been described; these include Devic's disease, Balo concentric sclerosis, Schilder's diffuse sclerosis, and Marburg multiple sclerosis. There is debate on whether they are MS variants or different diseases. [31] Multiple sclerosis behaves differently in children, taking more time to reach the progressive stage. [5]
Hence the name "tumefactive multiple sclerosis". When the demyelinating lesion appears alone it has been termed solitary sclerosis. [4] [5] [6] These cases belong to a multiple sclerosis borderline and there is currently no universal agreement on how they should be considered. Tumefactive multiple sclerosis is a demyelinating and inflammatory ...
This is a list of notable people with multiple sclerosis, a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. [1] This damage disrupts the ability of parts of the nervous system to transmit signals , resulting in a range of signs and symptoms , including physical, mental , and ...
The scleral ring or sclerotic ring is a hardened ring of plates, often derived from bone, that is found in the eyes of many animals in several groups of vertebrates. Some species of mammals, amphibians, and crocodilians lack scleral rings. [1] The ring is in the fibrous outer layer of the eye, called the sclera.
