Balo Disease is a rare and progressive variant of multiple sclerosis. It usually first appears in adulthood, but childhood cases have also been reported. While multiple sclerosis typically is a disease that waxes and wanes, Balo Disease is different in that it tends to be rapidly progressive. Symptoms may include headache, seizures, gradual paralysis, involuntary muscle spasms, and cognitive loss. The alternative names for Balo Disease, concentric sclerosis or Balo concentric sclerosis, refer to the fact that Balo Disease is characterized by bands of intact myelin (the sheath of fatty substances surrounding nerve fibers), alternating with rings of loss of myelin (demyelination), in various parts of the brain and brain stem. The symptoms of Balo Disease vary, according to the areas of the brain that are affected. Symptoms may progress rapidly over several weeks or more slowly over two to three years.
