-
- Balo disease is a degenerative condition of the brain characterized by
- progressive spastic paralysis, and various other neurological symptoms
- depending on which parts of the brain are affected. The disease affects
- children of both sexes; it may progress rapidly over several weeks, or two to
- three years. The cause is unknown.
-
- Symptoms
-
- Balo disease appears in childhood. The child gradually becomes spastic and
- paralyzed. Other symptoms are also neurological, and depend on the areas of
- the brain involved. Intellectual functions, coordination, and regulation of
- certain physiologic functions may be impaired.
-
- The areas of degeneration can be localized in any part of the brain
- (e.g., the cerebral hemispheres, the cerebellum, and the brainstem). They
- consist of irregular patches in concentric circles, and are characterized by
- the destruction of myelin, an "insulating" material which surrounds the axons
- (nerve fibers) of the individual neurons.
-
- Causes
-
- The cause of Balo disease is unknown. It may be an unusual form of
- Schilder's disease, a more severe form of brain demyelinization. (The causes
- of this condition are not known, either.) Autoimmunity may be involved, or a
- virus infection with a very long latent period ("slow virus") may be
- responsible.
-
- Affected Population
-
- Balo disease affects children of both sexes.
-
- Related Disorders
-
- Balo disease may be an unusual form of Schilder's disease, characterized by
- demyelinization (destruction of the insulating myelin sheath surrounding
- nerve cells) of large areas of the brain. Schilder's Disease differs in the
- way the demyelinization progresses and is more severe than Balo disease.
-
- Therapies: Standard
-
- There is no known treatment for Balo disease at present. Care is supportive
- and symptomatic.
-
- Therapies: Investigational
